1. Introduction of silicon manganese alloy
(1) Concept: silicon manganese alloy is an alloy composed of manganese, silicon, iron and a small amount of carbon and other elements. It is a kind of iron alloy with a wide range of uses and large yield. Silicon manganese alloy is a compound deoxidizer commonly used in steelmaking with remarkable deoxidization effect. It is also a reducing agent for metal manganese produced by low carbon iron and electrosilicon thermal method in production. The silicon manganese alloy can be smelted by continuous operation in large, medium and small sized ore furnace.
(2) Silica manganese is more abundant in southwest China, Yunnan, Guizhou, Guangxi and Hunan. The raw materials of producing silicon manganese alloy are manganese ore, manganese rich slag, silica, coke and so on.
(3) Common brand: FeMn68Si18 FeMn65Si17 FeMn60Si14
(4) Raw materials: manganese ore, manganese rich slag, coke, silica, lime, etc.
2. the purpose of silicon manganese alloy:
Silicon manganese alloy is mainly used as the intermediate material of deoxidizer and alloying agent in iron and steel production, but also the main raw material of middle and low carbon ferromanganese production
3. Production method of silicon manganese alloy:
Silico-manganese alloys are produced by reducing manganese oxide and silicon dioxide in manganese ore (including manganese-rich slag) and silica with carbon in ore furnace.
4, silicon manganese alloy properties:
Block, silver luster, specific gravity 6.0-6.4.
