The dissolution point of high carbon ferrochrome powder is 1550℃. In order to make the slag and iron discharged successfully, the molten steel in the specific production and manufacturing should exceed the temperature of 100℃, so the dissolution point of slag should be 1650℃. If the slag dissolving point is slightly lower and the temperature in the furnace is low, then the slag can be discharged, but the molten steel is difficult to be discharged because of the small hydrogen pressure, and the situation of less iron and more slag is appeared. When the slag is discharged only, the iron can not be discharged, which leads to very large damage.
In the metallurgical industry chain, high carbon ferrochrome powder is mainly used in the production of carbon ferrochrome non-ferrous metals and metal materials low high carbon ferrochrome powder. Carbon ferrochrome nonferrous metals are used as additive materials for the production of a variety of special steels with high toughness, corrosion resistance, wear resistance, heat resistance and air oxidation resistance, such as heat resistant steels, rolling bearing steels, tool steels, alloy steels, etc. Metal material carbon ferrochrome is mainly used with cobalt, nickel, tungsten and other elements smelting special aluminum alloy.
Ferrochrome slag is a kind of high quality limestone - like building decoration material. Its production and processing with a variety of concrete, with other sand and stone materials do not have the advantage. Ferrochrome slag production and processing into sand gravel, with high compressive strength and surface especially not smooth characteristics. Ferrochrome slag sand gravel, in the hygroscopicity and porosity of the state of its compressive strength will exceed limestone, and similar to limestone.
