46含量Chromite sand 铸造面砂铬矿砂AFS 40-45
46%铬含量的铬矿 AFS 40-45 不同于冶金级别的铬铁矿砂，它是按照消失模铸造、熔模铸造、覆膜砂铸造、自硬砂铸造等铸造工艺的要求来确定其粒度分布和细度的。美国铸造协会AFS( American Foundry Society）和中国行业标准都对铬矿砂的细度做了规定、/span>
The Chromite Sand AFS 40-45 with 46% chromium content is different from metallurgical grade chromium iron ore sand. It is determined based on the requirements of casting processes such as lost foam casting, investment casting, coated sand casting, and self hardening sand casting to determine its particle size distribution and fineness. The American Foundry Society (AFS) and Chinese industry standards both specify the fineness of chromite sand.
