Being as two layer refractory lining on valve plate and valve body,light mullite and phosphate corundum refractory castables are taken as heat isolation and heat resisting layers respectively.

Wear resistant castables for main and assistant furnaces of large gaseous suspension calciner were prepared by using fused brown corundum(5~8 mm,3~5 mm and ≤0.

Study on super-low cement refractory castables;

A laboratory study on refractory castables with lightweight, high-strength and insulation was done using light clay, shale ceramisite and light high-alumina as light aggregate, using fine fly-ash as fines and using the technology of composite admixture.

Effect of dosage and particle size distribution of SiC on performance of refractory castable

The measures of increasing the properties of corrosion-resistance and of improving manufacture process of high-strength aluminous refractory castables were taken.

Based on the results of three kinds of water reducer solely added in refractory castable,and orthogonal test was used to determine the optimal mix ratio.

Study on performance of abrasion-resistant castable with high strength;

Now, the castables were often used as outlet s liner refractories on the new dry cement kilns in our country, and the chief factors.
