High Carbon Ferro Chrome Lump for Casting
Ferrochrome is a kind of ferroalloy which mainly composed by Iron and Chrome,It‘s one of the basic alloying constituent for steel industry.
Types of Ferrochromium
1. High-carbon ferrochrome
High-carbon ferrochrome is usually used as an alloying agent for
ball steel (0.5%~1.45%Cr), tool steel, die steel (5%~12%Cr), and
high-speed steel (3.8%~4.4%Cr), and can harden steel. Increase the
wear resistance and hardness of steel.
2. Medium and low-carbon ferrochrome
Medium and low-carbon ferrochrome is used in the production of
medium and low-carbon structural steel, carburizing steel, gears,
high-pressure blower blades, valve plates, etc.
3. Micro-carbon ferrochrome
Micro-carbon ferrochrome is mainly used to produce stainless steel,
wear-resistant steel, and heat-resistant steel.
Specification
Function
Ferro chromium has three functions in the steelmaking and casting
industry.
1. Ferro chromium alloys can remove oxygen from molten steel in the
steelmaking process, and other impurities such as sulfur and
nitrogen in steel can also be removed with other ferroalloys.
2. Alloy additives. According to the composition requirements of
the steel type, ferro chromium alloy elements are added to the
steel to improve its performance of the steel.
3. As inoculant, ferro chromium alloy is added to molten iron
before casting to improve the crystalline structure of cast iron.
