Product Description
Cost-effectiveness over chrome magnesite bricks manufacturer in india
Magnesite Chrome Brick is made of some preliminary synthesis high purity raw materials. The high purity raw refractories should be high pressure formed, ultra high temperature fired and then go through some other post-treatment process and system, finally made the magnesite chrome brick. The magnesia chrome brick has high room temperature compressive strength, low porosity, strong erosion resistance and scouring resistance, etc.
ORDINARY MAGNESITE CHROME BRICK :
● Material and Technique : made from sintered magnesia and chrome ore and sintered at high temperature
● Property : having higher bulk density and stronger thermal resistance than the magnesite brick
● Application : used in cement rotary kilns, glass kiln regenerators, permanent lining of steel furnace permanent and refining ladle permanent lining of refining ladle.
DIRECT-BONDED MAGNESITE CHROME BRICK :
● Material and Technique : made of low impurity chrome ore and high purity magnesia and fired at high temperature over 1700?
● Property : strong slag resistance and good performance under high temperature
● Applied in cement rotary kilns, electric arc furnaces, and non-ferrous metal furnaces
REBONDED MAGNESITE-CHROME BRICK AND SEMI-REBONDED MAGNESITE-CHROME BRICK :
● Material and Technique : made with synthetic fused magnesia, shaped under high pressure and fired at ultra high temperature
● Property : Thanks to the high purity of the raw material, the product has good high temperature performance, high thermal resistance, low air-permeability, and strong slag resistance
● Application : used in tapping hole of AOD furnace, the lower vessel of vacuum chamber and snorkel of RH furnace, and the slag line of high temperature furnaces.

Magnesia chrome brick feature:
1.High temperature strength,
2.High refractoriness under load,
3.Low thermal conductivity,the small expansion,
4.Low porosity, high compressive strength,
5.Good thermal shock resistance and slag resistance,anti-spalling,
6.Strong corrosion resistance
7.Strong resistance against alkaline substances,the acid resistance better than the magnesia refractories.
Quality Assurance
Quality Assurance
The quality assurance system consists of the following steps:
a.Inspection and Control of incoming raw materials:According to the chemical content,raw materials are classified into different levels to ensure quality of brick first.
b.Inspection and control of the process:During the production,every brick will be weighed twice strictly to reduce the error of weight .
c.Inspection of product Standardization of quality of each product by process control and experimentation.
d.Taking corrective measures whenever deviations are noted.
e.Quality audit by quality management.Before delivery, the inspectors will inspect the size,appearance,physical and chemical properties of brick again in factory.
