Products Description
In the 1990s, due to the slow development of the stainless steel industry and the limited increase in stainless steel production, the production capacity of ferrochrome was seriously oversupplied, and the price of ferrochrome hovered at a low level, which seriously affected the production of ferrochrome and technological progress.
In order to survive, some production plants reformed old equipment to reduce production costs, and carried out experimental research on some new processes. The fixed preheating device-shaft kiln replaced the original rotary kiln to make the preheated pellets or lump ore break and The amount of grinding is greatly reduced.
In addition, a steel strip sintering furnace with high thermal efficiency has been developed to replace the original double furnace. The Swedish Chrome Company adopts the plasma shaft furnace production process. The chrome powder ore, coal powder and silica are weighed and batched, and sent to the grinding and drying machine for grinding. , mixing and drying, the gas is transported to the charge distributor, and the mixture is sprayed into the shaft furnace filled with coke from each tuyere in the lower part, and reacts in the high temperature area generated by the plasma arc in front of the plasma generator, coke and limestone or a small amount of chromium After drying, the lump ore is put into the furnace from the top of the furnace to carry out smelting reduction reaction in the high temperature reaction zone, and produce ferrochromium.
This process is characterized by high ferrochromium quality, high chromium recovery rate, strong adaptability to chromium ore, coke saving and effective recovery of waste heat.

Replacing the original rotary kiln with a fixed preheating device-a shaft kiln makes the amount of preheating pellets or lumps broken and ground greatly reduced. In addition, a steel strip sintering furnace with high thermal efficiency has been developed to replace the original double furnace. On the one hand, our country has invested in South Africa, Zimbabwe, Kazakhstan, India and other countries rich in chromium resources to build new ferrochrome mines and ferrochrome plants, using advanced technology and equipment to produce ferrochrome; Make improvements, transform production equipment, build new ferrochrome electric furnaces, import chrome ore and develop domestic chrome ore to produce ferrochrome.
In short, the continuous development of the world's ferrochrome production technology, because the development of the stainless steel industry plays a guiding role in the development of ferrochrome, that is, the ferrochrome market formed by the law of supply and demand is closely related to the situation of the stainless steel industry. Furnace grade ferrochrome and high carbon Ferrochromium is currently the main source of chromium used in stainless steel production.
Due to the needs of product quality and production cost, ferrochromium manufacturers must produce efficiently and pursue the maximization of profits, which also promotes the optimization and development of those using cheap raw materials. A new technology that saves energy and labor, simple and reliable technology, stable and easy operation, and low investment
