	CaO	Al2O3	SiO2	Fe2O3	TiO2	MgO
A	53-59	30-38	≤3.5	≤1.5	≤2.0	≤1.0
B	50-56	35-44	≤4.0	≤2.0	≤2.0	≤1.0
C	47-53	41-45	≤3.5	≤1.5	≤2.0	≤1.0
D	60-65	27-33	≤5.0	≤2.0	≤2.5	≤1.0
E	67-72	23-27	≤5.0	≤2.5	≤2.5	≤1.0

 

Sintered Calcium aluminate:

Specification	Chemical Composition(%)
	CaO	Al2O3	SiO2	Fe2O3	TiO2	MgO
A	≥40	50-55	≤5.0	≤2.5	≤2.5	/
B	53-59	30-38	≤5.0	≤2.5	≤2.5	/
C	50-56	35-44	≤5.0	≤2.5	≤2.5	/

 

 

 The size and specifications can be customer-made!

 

 

Calcium aluminate advantages:

 

1) Uniform chemical compositions, low melting point, high melting speed, and short smelting time;

 

2) It has no fluoride and doesn’t erode furnace lining and ladle, and it is compact, non-absorbent,

    and easy to storage as well;

 

3) Stable phase and fast dust-reducing speed, rapid desulfurization effect stabilized at 60%, and

   suppresses phosphorus into molten steel;

 

4) Improving the protective effect and reducing erosion to ladle lining.
