Silicon manganese alloy is a kind of iron alloy with a wide range of uses and a high yield. It is composed of silicon, manganese, iron, carbon and other small amount of elements. It is mainly used as a deoxidizer and alloy additive in steelmaking. If silicon and manganese are used alone for deoxidation under the same conditions, the burn rate will be much higher than that of silicon manganese alloy, because silicon manganese alloy is widely used, not only for deoxidation but also for the production of low carbon ferromanganese and reducing agents for the production of metal manganese by electrosilicothermal method
There are two kinds of silico-manganese alloy indexes: 6517 and 6014, but many customers want silico-manganese of 6818, which actually refers to 6517. The carbon content of these two indexes is no higher than 2.5, the phosphorus content is no higher than 0.3 and the sulfur content is no higher than 0.05
