In the stage of industrial development, the importance of casting is particularly prominent, and what is the main waste of casting? What are the main methods for handling casting waste? What equipment is required to handle casting waste?
What are the main components of casting slag?
Generally speaking, it is possible to treat the waste residue of casting factories mainly by analyzing and treating these solid and liquid waste residue resources. Different enterprises have different understandings of the waste residue produced by casting factories. Here, we mainly discuss the problem of treating solid waste in the waste residue of casting factories.
Casting slag generally contains pig iron, scrap steel, waste machine iron, spheroidizing agent, vermiculite, silicon iron, carburizing agent, sulfurizing agent, inoculant, chromium, manganese, molybdenum, copper, etc. Auxiliary materials include sand, powder coal, clay, Penglun earth, resin, etc. The types of slag produced by different foundries are different, so we need to provide detailed instructions on the treatment of casting slag based on different types of waste and impurities.
Casting waste disposal plan
Referring to the waste treatment methods of foreign foundry enterprises, there are several aspects to treating foundry waste residue:
(1) The disposal of waste slag and sand from casting factories can be processed by grinding machines to become renewable building engineering materials and composite materials in China. Landfilling is also a commonly used information processing method.
(2) After treatment, the wastewater from the foundry is precipitated, dried, and then ground into powder to produce concrete raw materials.
(3) The treatment of molten iron slag in casting waste is mainly through the deep processing of grinding machines, the treatment of road building materials or buried inert materials.
(4) The waste lining in the furnace and ladle used for processing foundry slag can be processed into fine powder with a size of 325 mesh or less using a grinding machine, which can be used as secondary raw materials for cement and brick factories.
(5) Of course, we can directly collect relatively fine dust from the casting equipment, and our teachers can choose to analyze the direct impact and apply it to materials such as recycling in melting furnaces, cement fillers, and concrete.
What equipment is required to handle casting waste?
In the process of recycling and treating casting waste in China, a common and commonly used method is to add a mill production line to treat solid waste. What kind of milling equipment should be used? How about the cost? I believe many companies are concerned about this issue.
