Customized Size CaO Pre-melting Refining Slag for Chemical Industry 38-42% Al2O3

CaO Pre-melting refining slag

CaO Pre-melting refining slag is made of limestone (CaO),Magnesite (including MgO), dolomite (containing CaO · MgO), toxic heavy stone (including BaO) and fluorite (containing CaF2) in the cupola by sintering and melting.

Features & Advantages of  Pre-melting refining slag:

1, the chemical composition of uniform, low melting point, melting speed, can shorten the smelting time;

2, does not contain fluorine, does not erode the lining and ladle;

3, the structure of dense, non-absorbent, easy storage and storage; due to stable material, slag quickly, can reduce the dust pollution of steel plants, comprehensive and stable refining process;

4, does not contain hydrogen, nitrogen, carbon and other impurities, is conducive to improving the quality of steel.

Chemical & Physical Index:

Applications Pre-melting refining slag:
