Today the company has imported a batch of raw materials, 
and our engineer is checking it. 
Come with me to see the scene and learn by the way.
Calcium silicon as our raw material. 
Mainly used as an inoculant for cast iron. 
Silicon calcium has strong reducing ability 
and is also used as a deoxidizer for high-quality steel. 
Since calcium is very active at the steelmaking temperature, 
the effect is not easy to stabilize, 
so it is advisable to add some kind of slowing agent.
At the same time, in the production of cast iron, 
calcium silicon can improve the performance of 
cast iron more effectively than ferrosilicon. 
Silicon-calcium alloy is not only an effective inoculant 
to promote the formation of spherical graphite, 
but also has the effect of deoxidation, desulfurization, 
denitrification and silicon addition.
Our calcium silicon is purchased from regular manufacturers 
such as Ningxia Yinchuan and Shaanxi Fugu. 
Generally, the silicon content is above 55%, 
and the calcium content is above 30%.
The spheroidizing agent products produced by Nanjing Dyfeng 
have optimized raw materials and quality assurance. 
They can also be customized according to 
the standards required by customers. 
Welcome to consult and place an order~
Follow me, the youngest girl in the factory, 
see you next time, bye~
