Fire Clay Insulation Refractory Bricks with SiO2 Content % International Standard

 Fire clay insulation refractory bricks used for coke oven 

Clay brick is the refractory brick with 30%- 48% alumina content. Clay brick is weak acid product. Because of its rich resources, simple production process, low cost, it is widely used.

characteristics of fire clay bricks:

1,high density

2,good thermal shock resistance

3,excellent volume stability at high temperatures

Lightweight clay refractory brick is with a light weight, small thermal conductivity and high refractoriness. Its drawback is high air permeability, loose structure, low mechanical strength, anti-slag and poor anti-harmful gas erosion ability, easily to be damaged in long-term use. Therefore, the density of 0.4-0.8g / cm3 fireclay products are generally used as high temperature insulation components, the density of 1.0-1.3g / cm3 fireclay product as an insulation wall between industrial boiler pipe.

2.Quality Assurance
1)Going out the furnace→checkout→packing→qualified product→putting in storage→sale,
2)The process from raw to product are strictly tested by equipment.
1.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.
2.Inspection and control of the process: during the production,every brick will be weighed twice strictly to reduce the error of weight .
3.Quality audit by quality management:  inspection of product standardization of quality of each product by process control and experimentation, taking corrective measures timely whenever deviations are noted.
4.Before delivery, the inspectors will inspect the size,appearance, physical and chemical properties of brick again in factory.
