Introduction of high carbon ferromanganese particles

High carbon ferromanganese is to break the pieces of ferromanganese into small particles of various requirements. The common content in the factory is 65 high carbon ferromanganese and 75 medium carbon ferromanganese. Usually, various granules can be customized according to the requirements of customers.

Ferromanganese particles in steelmaking, used as deoxidizer and alloy additives, is a large amount of ferroalloy. The manganese ore used for smelting ferromanganese generally requires ferromanganese to contain 30~ 40% manganese, ferromanganese ratio is greater than 7, phosphorus and manganese ratio is less than 0.003.

Before smelting, the manganese carbonate ore must be roasted first, and the powder ore must be sintered to form blocks. The ore with high iron and phosphorus content can only be used in combination, or the manganese rich slag with low iron and phosphorus can be obtained through selective reduction.

Smelting with coke as reducing agent, some plants also with lean coal or anthracite. The auxiliary raw materials are mainly lime, and silica is generally added when smelting manganese silicon alloy.

Steel castings should be used after heat treatment, because there are holes, cracks, shrinkage cavity and porosity, coarse grain, uneven structure and residual internal stress in the cast steel castings, so that the strength of steel castings, especially the plasticity and toughness are greatly reduced.

Henan star high carbon ferromanganese particle manufacturers supply a large number of ferromanganese, steelmaking deoxidizing effect is good, used as deoxidizer and alloy additives in steelmaking, is the amount of more ferro-alloy, product size can be customized, welcome your purchase!
