Technical Field
The invention relates to the technical field of steel making, and mainly relates to a silicon-manganese-carbon alloy ball and a preparation process thereof.
Background
During smelting medium and high carbon steel in a steel converter, the carburization and deoxidation alloying tasks are generally completed by adding alloy and recarburizing agent along with steel flow or at the bottom of a ladle in the tapping process. Firstly, because the recarburizer is granular, when the recarburizer is large in granularity, the recarburizer floats on the molten steel surface, the carbon recovery rate is low, generally 80-90%, when the recarburizer is small in granularity, the recarburizer is easy to oxidize and unstable, the addition amount is large, the cost is high, and the working conditions are deteriorated;
secondly, the granular recarburizer easily causes large heat loss due to violent boiling of molten steel in the ladle and is not beneficial to temperature control; in addition, the impurity content of the carburant is high, and the carburant is easy to absorb water, so that the cold drawing performance of steel is deteriorated, and the deep processing is difficult; furthermore, the carbon content in the steel is not uniform, resulting in carbon segregation.

Furthermore, the silicomanganese carbon alloy ball is correspondingly punched by a drilling machine before compression molding and demoulding, so that the silicomanganese carbon alloy ball is arranged in a honeycomb shape.
Further, in the step S2, the particle diameter of the ground silicon powder, manganese powder, carbon powder, graphite powder, phosphorus powder and sulfur powder is between 1mm and 3 mm.
