What is the production method of low carbon ferrochrome furnace?
As a kind of ferrochrome with low carbon content, low-carbon ferrochrome is an important additive in steelmaking and casting. At ordinary times, our common stainless steel and high alloy ferritic steel are smelted by adding low-carbon ferrochrome in smelting. It can be said that low-carbon alloys are widely used.
What is low carbon ferrochrome?
Low carbon ferrochrome is a kind of ferrochrome with carbon content below 0.25. Its production raw materials are silicon chromium alloy, chromite and lime, which are smelted by various smelting methods. Low carbon alloy is used in many industries. In the steel-making industry, low-carbon ferrochrome is a necessary ferroalloy additive for the production of stainless steel and special steel.
Production method of low carbon ferrochromium
In general, ferrochrome will be produced by two production methods: high-carbon ferrochrome refining method and electro silicothermic method. Electro silicothermic method is to reduce chromium and iron oxides with silicon in silicon chromium alloy under the condition of making alkaline slag in the circuit, so as to produce medium and low-carbon ferrochrome.
High carbon ferrochrome refining method is to refine high-carbon ferrochrome with chrome ore. in addition, oxygen can be used to refine low-carbon ferrochrome. If low-carbon ferrochrome with chrome ore concentrate is used, the slag in the refining furnace has large viscosity and high melting point. In the smelting process, the temperature must be very high. Therefore, the power consumption is high, the life of furnace lining is short, and the carbon content is not easy to drop, If oxygen is used to convert low-carbon ferrochromium, it has great advantages and many benefits, such as high productivity, low production cost, high recovery rate and so on!
After reading it, you will find that low-carbon ferrochrome is not only widely used, but also exquisite in the process of producing low-carbon ferrochrome. People can't help but sigh that the production method of low-carbon ferrochrome is amazing!
