Application of graphite powder in casting

Jan 15, 2021 / 133 views

Casting graphite powder has metallic luster, soft quality, stable chemical properties, not affected by strong acid and alkali. Less harmful impurities, iron, sulfur, phosphorus and nitrogen, molybdenum, low hydrogen content, high temperature resistance, heat transfer, conductive, lubrication, and plasticity, mainly lies in hebei, henan, hunan, shanxi, Inner Mongolia and other regions, casting graphite graphite, graphite powder, graphite, graphite sand, fixed carbon content how much divided into 25, 35, 45, 55, 65, 70, 75, 78, 80, 83, 85, 88, a total of 12 level. Specifications are :100 mesh, 200 mesh, 325 mesh, 800 mesh, 1200 mesh, 2000 mesh, 4000 mesh, 5000 mesh, 8000 mesh, 10000 mesh, 12000 mesh and other models.

Its common uses are :(1) graphite powder has a good lubrication effect, improve the compaction of sand fluidity, air permeability decline, sample ejection resistance to reduce, improve the performance of molding sand. (2) the foundry industry, the graphite coated on the surface of the solid, can form a smooth film adhesion strong, this is the appearance of graphite good coating performance, it is a good casting remover casting commonly used graphite powder have crystalline graphite powder (flake graphite powder) or aphanitic graphite powder (earthy graphite powder, also known as microcrystalline toner, black lead powder).

Since its establishment, Henan Star Metallurgy Group has been based on the production and research and development of new metallurgical materials . The graphite powder produced has complete specifications and stable price, which has been unanimously recognized by new and old users. We are looking forward to your purchase!
