Light weigt bricks feactures:
1. It has advantages with small bulk density, high cold crushing strength, and high refractoriness under load, small dimension tolerance and good thermal shock resistance.
2. It has the lowest and most stable thermal conductivity in various insulating refractory bricks
3. It can reduce the total weight of furnace body and the thickness of furnace wall effectively, improve heat efficiency, lower energy consumption, improve work conditions and production efficiency, and considerable economic benefit can be obtained.
Application of light weight bricks:
It is not only widely used in insulating layers of various of thermal processing equipments, such as hot blast furnace, coke oven, glass kiln, etc, but also apply to linings in parts of furnace without strong high-temperature molten material erosive.

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.
