Mysteel Foundry Enterprise! A better choice for scrap base.

Foundry enterprises need to purchase different types of scrap steel according to their own production products. Common types of casting scrap steel include Q235 scrap, punching beans, corner grooves, cold and hot rolled materials, cold rolled briquette, steel shavings, steel Scrap, pig iron filings, iron pin compacts, silicon steel sheets, etc. However, unlike steel mills, foundries have stricter requirements on the element content and “impurities” of scrap steel. First of all, the most common element content is the requirement for manganese. For example, foundries that produce high-manganese steel castings need to purchase high-manganese scrap, so as to maximize production cost savings. Another example is the foundry that produces high-grade gray cast iron, which also needs to purchase scrap steel with high manganese content. For ductile iron casting companies that produce ferrite as the matrix, scrap steel with low manganese and low chromium should be selected. In addition, some foundry companies that have requirements on the hardness of castings will specially purchase alloy scraps containing chromium, nickel, molybdenum and other elements. Secondly, casting enterprises have higher requirements for “impurities”. For scrap steel such as steel plate scraps, corner grooves, etc., foundry companies usually only choose “new materials” instead of purchasing “old materials” with more rust. In order to obtain high-quality molten iron, some foundry companies will also have a production link for rust removal. In addition, if the scrap steel purchased is extensively classified and contains a lot of impurities, some foundry enterprises also need to select and classify the alloy scrap with high chromium and molybdenum content, so as to avoid the hardness of the castings exceeding the standard and causing the castings to be scrapped. In terms of price, the purchase price of scrap steel by foundries is often higher than that of steel mills, but it is not absolute. The higher the size requirements, the higher the element content requirements, the higher the impurity content requirements, the higher the corresponding processing costs, the labor costs for sorting and sorting, etc., and the purchase price will naturally rise. That is, under normal circumstances, the scrap purchase price of ductile iron castings casting enterprises > the purchase price of scrap steel of gray iron castings casting enterprises > the purchase price of scrap steel of steel casting casting enterprises > the purchase price of scrap steel of steel mills. The material type and size of scrap purchased by some steel casting foundries are not much different from those of local steel mills, and the purchase price of scrap steel is basically the same as that of local steel mills.
