company news about How to make magnesia calcium refractory brick?

In order to make full use of high calcium magnesite, can manufacturing magnesia calcium refractory brick.

The production process of the preparation of magnesia calcium brick and brick two processes for clinker system. Preparation of magnesium calcia clinker, ingredients should control the ratio of calcium and silicon (C/S) in 2.2 ~ 3, AL2O3 should be less than 2%, while adding 0.3% apatite as stabilizer, adding 0.5 ~ 0.7% iron ore concentrate powder as the mineralizer.

High calcium magnesite, apatite, iron concentrate according to the proportion in the cylinder mill grinding. Size requirements: fine powder >0.088 is greater than 90%. Powder by ball forming in rotary kiln burning.

With high calcium and magnesium sand as raw material, production technology for firing brick magnesite brick, at 1600 to 1680 DEG C firing, thereby preparing the HISTEP calcium magnesium brick - magnesia calcium refractory brick.
