How to correct the remelting of electroplating waste in zinc alloy die casting manufacturers?
The electroplating waste of zinc alloy die casting manufacturers should be smelted separately from the non electroplating waste, because the electroplating waste contains copper, nickel, chromium and other metals that are insoluble in zinc, and will remain in the zinc alloy as hard particles, causing difficulties in polishing and machining. When nickel exceeds 0.02% in zinc alloy, no matter where it is die-casting, polishing or electroplating, it will bubble.
The remelting operation procedure of electroplating waste in zinc alloy die casting factory is as follows:
(1) The crucible is filled with a certain amount of zinc alloy liquid, and then a layer of zinc alloy ash is sprinkled on the zinc alloy liquid. The purpose is to use the buoyancy of the ash to support the added electroplating waste, so that the electroplating waste cannot contact the zinc alloy liquid. When adding electroplating waste, pay attention to the amount.
(2) When the electroplating waste is decomposed by heat, the zinc alloy with low melting point melts and flows into the zinc liquid below the ash, while the electroplating waste with high melting point remains on the ash.
(3) When picking up the ash, be sure to pay attention to the operation. Use the slag raking raking raking raking raking to gently remove some ash, cut diagonally, and pick up the electroplating waste and ash from the bottom of the ash. During this process, there should be no agitation to prevent the electroplating waste from falling into the zinc alloy solution.
(4) Scrape the slag on the surface of zinc alloy liquid, and then see if it needs to be treated with refining agent.
The zinc alloy die casting manufacturer reminds that correct and standardized operation is a way to ensure the effectiveness of handling matters, and correct operation steps to avoid work-related injuries are also a way to ensure the safety of employees.
