High temperature endurable high alumina refractory brick/tile for tunnel kiln in Vietnam is made by clay clinker or light clinker and plastic clay as the main raw material, usually fuel production, but also can send or chemical foaming method porous structure. Common light chamotte bulk density of 0.75 ~ 1.2g / cm3. It refers to containing AL2O3 30% ~ 46% of lightweight refractory products, mainly for industrial kilns does not melt and no erosion of the contact action of gas insulation layer material, the using temperature is 1200 ~ 1400 ° C.

5. Lower heat storage than denser refractory.
6. Heats quickly and economically to operating temperature.

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.
