calcium silicon supplier

As one qualified calcium silicon supplier, must know well about the production, model number and application of the calcium silicon, Huatuo will share it as followings:

How to produce the calcium silicon?

Firstly to produce the calcium carbide in one electric furnace, then to compound the calcium silicon with the raw material of silica and carbonaceous reducing agent in the other electric furnace. This way is called Two-step way calcium silicon production by calcium silicon supplier.

There are some details need to pay more attention in the production of calcium silicon such as when smelt it, need to simmer, so needed carefully maintain the furnace condition and increase the permeability of material surface; the electrode need to insert into the charge deeply and stably then can prevent the collapse of the material and reduce the radiation of calcium and the loss of heat energy, what is more, when cast the alloy, the oxide is not sufficiently reduced, and the raw material will contains a certain amount of impurities, after 3~5 minutes of general sedation, the slag will slightly heavier density sinks into the bottom, and then slowly pour the tundish, requiring”slow down, fast back”. When found the surface of the alloy to be white and shiny, then stopped the casting immediately to avoid alloy slag inclusion.

What is the model types general used for the calcium silicon?

General provided Ca31Si60 and Ca28Si55 by the calcium silicon supplier, called CaSi6030 and CaSi5528, the content of calcium is not less than 30% and 25%, and content of silicon will be 55%~65%, of course, there are also other element like aluminum,sulfur,carbon and phosphorus etc, they always in the particle size of natural size and standard size, the standard size is general 10-60mm.

The important application in steelmaking and foundry.

Silicon and calcium have a great affinity for oxygen, calcium also has high affinity for sulfur, the deoxidation and desulfurization products are easy to float out, then can improve plasticity and impact toughness of steel, so will be used as deoxidizer and desulfurizer for steelmaking. As the calcium silicon supplier knows that in the foundry, the calcium silicon can also deoxidize, desulfurize ,denitrify and enhance silicon, what is more, it can be an effective inoculant, promote the formation of spheroidal graphite.

Anyang Huatuo Metallurgy Co.,Ltd as one professional calcium silicon supplier from China, which own the experience of ferroalloys for more than 10 years, what is more, they own advanced processing equipment, can provide you several different particle size, if you have any confused, welcome consult.
