Product Description

Description:
Luzhong Magnesia hercynite spinel bricks are new developed chrom free refractories for Cement Rotary Kiln. In order to serve under severe conditions,LZR magnesia-hercynite spinel bricks have excellent mechanical strength, good resistance to thermal shocking, and are highly resistant to chemical attack by vilatile alkaies and some slag. We manufacture and design MTL-III bricks to meet the requirements of a great variety of service conditions through quality control.with excellent performance,our products have been wide used in the domestic and overseas cement projects.

Characteristics:
Formation of uniform and stable coating
Thermal-shock resistance
Outstanding chemical attack resistance
Low thermal conductivity


Application: 
Sintering  zone of cement rotary kiln.
 
Specification of the bricks:
1.Top grade sintered magnesia;
2.High purity active spinel (hercynite)
