Calcium Metal Granules
, Production method: mixing method, layered charging method, silica heat method
,
Product Description
The main elements of calcium metal granules are calcium and silicon, with a calcium content of about 24-31% and a silicon content of about 55-65%. Its smelting method is mainly to reduce silica and calcium oxide with carbonaceous reducing agent. Adding calcium metal granules in the steel will produce a strong exothermic effect, and calcium will have a strong affinity with oxygen, nitrogen, hydrogen, sulfur and carbon. It facilitates the production of clean and high quality steel.

How to use calcium silicate alloy
Determining the amount of calcium silicate alloy to be added
The amount of calcium silicate alloy to be added is determined according to the quality of molten steel and the required chemical composition. Generally speaking, the amount of calcium silicate alloy added is 0.02% to 0.06% of the weight of molten steel.
Determine the addition time of calcium silicate alloy
The addition time of calcium silicate alloy is determined according to the molten steel temperature and chemical composition. Generally speaking, the addition time of calcium silicate alloy should be 5 to 10 minutes before pouring. If the addition time is too late, it will affect the deoxidation and alloying effect of the alloy.
Determine the addition method of calcium silicate alloy
The addition method of calcium silicate alloy can be divided into manual addition and mechanical addition. Manual joining mainly involves gradually spreading calcium silicate alloy on the surface of molten steel and letting it slowly sink to the bottom. Mechanical addition involves adding calcium silicate alloy lumps or powder to the molten steel through an automatic addition system.
Precautions
1. Calcium silicate blocks should be stored in a dry environment to avoid moisture or deterioration which may affect the adding effect.
2. Calcium silicate blocks should be stored separately, avoiding contact with acid, alkali and other substances.
3. The operator should reasonably control the adding amount and time of calcium silicate block, according to the actual situation, flexible control.
