[China Aluminum Network] I. Burns, burns Causes: Labor insurance products are not fully worn, violations of rules and regulations and accidents.

Precaution:

1. Carefully check the protective clothing (work clothes, safety helmets, protective masks, handkerchiefs, shawls, leg guards, protective footwear, etc.) before work. Unqualified labor protection is prohibited.

2. Strictly abide by the safety operation rules 3. Conscientiously do a good job in employee safety education, use typical accident cases as materials, strengthen the safety awareness of the workers 4. Regularly organize safety inspections, and conduct inspections on the safety equipment used.

5. Before the operation, check whether the tools and equipment are in good condition and meet the safety requirements. Unqualified tools and instruments are forbidden to use and dispose of:

1. When a burn or scald personal accident occurs, the on-site personnel shall promptly remove the burned and scalded personnel from the dangerous area, and 2. Burn or scald accidents occur.

When the 2.2 or less workers are generally burned and do not pose a threat to their lives, they immediately use the cold water to cool the injured on site to reduce the burn of the skin caused by high temperatures. At the same time, the staff of the medical office is notified to the scene to treat the wounded. Whether to send to the hospital for treatment 3. The personnel on site shall not forcibly remove the uniforms of the wounded, so as not to expand the injuries and burn the epidermis. 4. Those with serious injuries shall prohibit a lot of drinking water to prevent shock.

Second, the causes of furnace aluminum seepage:

1. Lax plugging, blocked sleeve failure 2. Oven brick cracked.

3. High temperature shock in the furnace.

Preventive measures: 1. Clean the hearth so that the oven eyes are clean and free of debris 2. Observe the operating instructions and carefully knock the eyes.

3. Special person to watch the furnace eye, carefully check after closing the furnace eye. .

Disposal measures:

1. Aluminizing the furnace eye, tapping the plug with a hammer and pressing the plug.

2. Use asbestos mud to stop bleeding.

3. Restart the caster and forcibly replace the plug.

4. Open the furnace door and add cold material (aluminum ingot) to the furnace eye to allow rapid cooling.

5. If the above measures still do not effectively stop the leakage, and the rescue time is too long, leakage of molten aluminum continues to be too large, there is no follow-up leakage measures, and then continue to rescue emergency situations that may cause casualties, they should immediately report the situation to the company's leadership, All personnel were ordered to evacuate from the scene of the accident 5. The reclamation team immediately organized personnel to clean the site of accumulated water to avoid the explosion of high-temperature aluminum liquid in water. III. Causes of aluminum liquid meeting water:

1. The factory is leaking rain. The rainwater encounters the high-temperature aluminum liquid in the chute or the high-temperature aluminum liquid in the slag box to cause an explosion. The aluminum liquid splashes the scald personnel.

2. Other water sources impinge on aluminum liquid and cause explosion of liquid aluminum. Preventive measures:

(1) Regularly carry out employee safety education and training to raise safety awareness. To enable employees to master the necessary safety technology, familiarize themselves with, understand and consciously implement safety procedures, and improve anti-accident capabilities.

(2) Strengthen safety supervision and management at the production site, ensure safety measures are implemented, and safety supervision is in place. In particular, the special personnel of the organization shall strengthen the regular maintenance and inspections at the top of the key parts of the mixing furnace to ensure that no leakage accidents occur. In the rain and snow days, it is necessary to strengthen the inspection of flood prevention work and close doors and windows in time.

(3) Pay attention to habitual violations. Strengthen the safety management of production sites, and conduct criticism, education, and evaluation on those who violate regulations and disciplines. Strengthen the investigation and handling of off-posts and sleeping positions, and strictly guard against lack of attention, lack of concentration, and lack of attention to work and inspections. Leakage caused.

(4) Pay close attention to weather changes especially during the flood season. Close all doors and windows of the workshop before heavy rains come and ensure that the ground is dry.

(5) In the event of roof leakage, personnel should be promptly organized to stop leaks, and at the same time, dispatch should be reported. When the accident is serious, preparations must be made before the series of blackouts. Once a dangerous situation occurs, report to the company immediately and notify the blackout.

(6) Do a good job of ventilation and cooling, and keep the ground clean and dry without water.

Disposal measures:

1. The furnace eye immediately plugs the furnace eyes, and at the same time opens the aluminum discharge hole for aluminum discharge so that the aluminum liquid in the chute flows into the accident residue tank. 2. The squad leader immediately ordered the production line to stop production, close the cooling water valve, fully organize the personnel to plug the leak, and timely inform the casting circulating water to stop the pump operation.

3. Oven workers should quickly prepare steel drills, plugs, and asbestos sleeves, pull out the original plug rods of the furnace eye, clean the slags of the furnace eyes with steel brazes, and quickly plug the furnace eyes with newly prepared plug rods and asbestos sleeves. Drop the ladle so that the liquid in the chute flows into the slag box;

4. Forehearth and Tianchang immediately promptly used leak-proof material to block the leakage point of the top of the mixing furnace roof to ensure that the roof is no longer leaking.

5. Inform site personnel and vehicles to leave the workshop.

6. Immediately set up the following on-site rescue teams and start their own rescue operations.

Fourth, the broken wire rope or trolley off causes: It is the furnace operator, transporter is not strong sense of responsibility.

(1) When the empty aluminum package is placed when the hook is not removed;

(2) Operation in violation of regulations, there is a sloping crane;

(3) The daily safety inspection is not careful, and there are phenomena such as wire rope slot and broken stock, which leads to accident prevention measures at the end.

(1) When the transporter feels abnormal sound behind the vehicle, he should immediately brake the vehicle.

(2) When the operator discovers that the aluminum hook has not been removed but the escalator has been started, he should immediately ring the warning sign to quickly operate the crane to move in the direction of the scooters, and at the same time reduce the tension on both sides to a small extent. If possible, raise the crane. The big hook will suspend the bag and will not cause serious consequences such as the falling of the crane and the breaking of the wire rope.

(3) Tianchang, transport workers, and aluminum exporters should strengthen the cooperation between the types of work and strictly abide by the safety operation regulations.

(4) Aluminium workers must strengthen their sense of responsibility and do a good job of monitoring. They must wait until the crane hook returns to a safe area before sending a signal to the transporter. The craft car driver is forbidden to start the vehicle without receiving an aluminum worker starting signal.

(5) When the transport worker receives a signal from the aluminum worker or the Tianchang worker, he must confirm once again whether the big hook has left the ring.

(6) Tianchanggong develops a good operating habit. After the big hook breaks from the ring, it should signal to the transporter.

Disposal measures:

(1) If the wire rope breaks up and drops from the ground, if there is spilled liquid of aluminum, the person should be evacuated as soon as possible. If possible, organize the personnel to use the leakage-proof material to intercept the aluminum liquid so that the liquid does not rush on the cable.

(2) If the aluminum trolley is removed, the site should be protected, and the injured should be rescued. Take appropriate measures to prevent further expansion of the situation. Reporting supervisors, on-duty dispatchers, and related leaders.

(3) If the molten aluminum strikes the cable, it may cause a short circuit or cause a short circuit, it should report the schedule, if necessary, after a series of power outages.

Fifth, can not put out the cause of aluminum liquid:

(1) The furnace temperature is low.

(2). There is too much slag at the mouth of the furnace.

(3) Too much cold material (cold aluminum) is accumulated.

Disposal measures:

(1) Using steel brazing, beat (2) with electric spark roasting.

(3) The refinement stops and the cold material and residue are removed.

6. Causes of blackout: external, internal fault or mechanical overload.

External treatment According to regulations, professional electricians should deal with electrical appliances.

Operator handling measures:

(1) The aluminum liquid in the sealing furnace and the bundling (2) discharge (medium, small, runner, degassing package).

(3) Sealing the furnace doors to prevent temperature drop, and the speed of processing aluminum billets online is faster.

FENCE SERIES

The Fence Series refers to a collection of different types of fences that are designed for various purposes. These fences are typically used for security, privacy, or aesthetic purposes. They come in different materials, styles, and sizes to suit specific needs.
Metal Mesh Fence: A metal mesh fence is a type of fencing made from metal wires woven together to create a mesh pattern. It is commonly used for various applications, including residential, commercial, and industrial purposes. Metal mesh fences are known for their durability, strength, and visibility.
Prison Security 358 Fence: The Prison Security 358 Fence, also known as a 358 mesh fence or anti-climb fence, is specifically designed to provide high-security protection. It is made of welded steel wire with closely spaced horizontal and vertical wires, forming a grid with 3-inch (approximately 76 mm) by 0.5-inch (approximately 12.7 mm) openings. The small mesh size makes it difficult for individuals to climb or cut through the fence, hence its common use in prisons, military installations, and high-security areas.
Hesco Barrier Military: Hesco barriers, also known as Hesco bastions or Hesco Concertainer units, are a type of temporary defensive barrier system used by the military and other organizations for protection against blast and ballistic threats. Hesco barriers consist of a collapsible WIRE MESH container lined with heavy-duty fabric and filled with soil, sand, or other locally available materials. They are commonly used to create fortifications, defensive walls, or flood barriers. The modular nature of Hesco barriers allows for easy transportation and rapid deployment in emergency situations.
These various types of fences and barriers serve different purposes, ranging from enhancing security to providing temporary protection in military or emergency situations. The specific choice of fence depends on the intended application and the level of security or functionality required.
