Description

Description 

The binary alloy composed of silicon and calcium belongs to the category of ferroalloy. Its main components are silicon and calcium. It also contains different amounts of impurities such as iron, aluminum, carbon, sulfur and phosphorus. Iron and steel industry is used as calcium additive, deoxidizer, desulfurizer and denaturant of non-metallic inclusions. Cast iron industry is used as inoculant and denaturant.

Effect of silica barium calcium inoculant:

  1. Strongly increase the graphitization core, refine the graphite, promote the gray cast iron to get A-type graphite, improve the strength, for nodular cast iron can make the graphite in nodular iron small, round, improve the spheroidization level.

  2. It can effectively reduce the undercooling degree of molten iron, promote the precipitation of graphite, significantly reduce the tendency of white mouth, reduce the relative hardness, and improve the cutting performance of casting.
