Hc FeCr
High carbon ferrochromium is an important raw material for the production of stainless steel. It is mainly used in the production of stainless steel, ball bearing steel, tool steel, nitrided steel, heat-strength steel, quenched and tempered steel, carburizing steel and hydrogen-resistant steel. This is because chromium is used in the production of stainless steel. plays a decisive role in stainless steel. Generally speaking, the three main raw materials commonly used for smelting high-carbon ferrochrome are chromite, coke and silica.

Product Introduction
Ferrous Chrome Lump Factory
Ferro Chrome Lump Alloy
When high-carbon ferrochrome manufacturers smelt high-carbon ferrochrome, they have requirements for the dryness of the coke. The main reasons are as follows:
Current Ferro Chrome Lump Prices
When wet coke is loaded into a closed furnace, it is easy to block the material tube and produce suspended material. When the material collapses, air will be brought in, and the pressure in the furnace will increase rapidly, which may cause an explosion accident.

Coke has large porosity, so it has strong water absorption. The fluctuation of moisture in coke first affects the accuracy of the fixed carbon ratio in the charge, and secondly, the evaporation of moisture also consumes heat. Especially when the material collapses, the wet material directly enters the crucible area and absorbs a large amount of heat, which increases power consumption.
After the wet coke is crushed, the powder often blocks the sieve holes or makes the sieve holes smaller. As a result, the coke powder cannot be screened out and the powder in the coke increases.

Product Description And Application
Ferrochrome: According to the different carbon contents, ferrochrome can be divided into four types: high carbon, medium, low and extra low carbon ferrochromium. High carbon ferrochrome can be used as alloying agent for ball steel, tool steel and high speed steel with high carbon content. It can improve hardenability, wear resistance and hardness of steel. It can also be used as additive for cast iron to improve wear resistance and hardness of cast iron. At the same time, it can make cast iron have good heat resistance. Extra low carbon ferrochrome is suitable as alloying element additive in steelmaking.
