Aluminum steel coil production process and production precautions
Aluminum steel coil production process
The primary aluminum ingots are put into the melting furnace, ignited and melted with natural gas, the slag is stripped and the waste is removed, equipped with aluminum alloy, the furnace is guided to the holding furnace, the aluminum water is poured, and it is hand-carved according to the engineering drawings, edge pressing, ribs, welding, polishing, painting, testing , Paste protective film, packaging air cushion cc film, packaging, loading arrangements for delivery.
Precautions for aluminum steel coil production
1. Air strips and slag inclusions
Causes: The production process is not strictly followed (the refining is not timely), the degassing outside the furnace is not in place (the dust collector is leaking), the aluminum sewage treatment is not timely, the excessive effect is not obvious, and the gas humidity is high.
Improvement measures: carry out one-time feeding, sprinkle covering agent according to the actual operation and processing technology, strengthen refinement, deal with the air leakage problem of dust collector, clean aluminum sewage treatment, improve the filtration system, and ensure the passage of aluminum water.
Two, long cracks
Cause: Rolling may cause damage or damage to the nozzle skin
Improvement measures: If the above-mentioned problems occur in the nozzle skin, the plate should be broken immediately to ensure that the nozzle skin is intact during the production process.
Three, black border
Causes: possible deficiencies in rolling: the processing technology is not timely, and the treatment of aluminum sewage is not very good.
Improvement measures: formulate production process and strengthen aluminum sewage treatment.
Fourth, scratches
Cause: The rolling may be caused by the friction of the surface of the aluminum alloy plate on the counter surface under the hydraulic shearing machine.
Improvement measures: rectify the lower counter of the hydraulic shearing machine.
