What is ferrochrome?
Ferrochromium is made using metallurgical grade chrome ore and can be divided into three categories, depending on the level of carbon in the alloy.
The three types of ferrochrome alloys are:
High-carbon (HC) ferrochrome (carbon content between 4% and 9%)
Low- and medium-carbon (LC & MC) ferrochrome (carbon content less than 0.5% for LC and between 0.5% and 4% for MC)
Ferrochrome-silico-chrome (FeSiCr)
Ferrochrome applications:
Production of steel, especially stainless steel with chromium content of 10 to 20%, is the largest consumer of high-carbon ferrochrome. Over 80% of the worldâ??s ferrochrome is used in the production of stainless steel.
The vast majority of ferrochrome produced is� charge chrome, which has a lower chrome content ratio. Used most commonly in stainless steel.
Low carbon� and� medium carbon� ferrochrome is used in the manufacture of special steels. Low carbon ferrochrome can be used to produce superalloys.
Ceramic Foundry Sand with the high quality bauxite as the raw material, blowing into the ball after remelting smelting, is a new type of steel casting foundry sand.Itâ??s characteristic as high temperature resistant,small amount of thermal expansion, easy collapse, good renewable performance,good casting properties, received the recognition from the cast made experts domestic and overseas. Widely used in all kinds of casting method,sand casting, special casting( casting, solid type, evaporative pattern casting, ladle flow guiding sand and so on ).Also used for shot peening, low expansion of high-temperature coated sand producing. 200mesh-270mesh used for evanescent mode coating producing. Adding 10-35% can effectively increase the air permeability, and suitable for using all kinds of casting binder.It has been used by numerous domestic and international cast iron and nonferrous metal casting production factories.
