Stove Al2O3 High Alumina Refractory Bricks Acid Resistant

Product descriptions:

The physicaland chemical index of white and red high alumina refractory brick

• The white and red high alumina refractory brick is an aluminum-silicon refractory product made of bauxite clinker with a certain amount of combined clay and having an Al2O3 content of more than 48%. The production process of high-aluminum bricks is basically the same as that of high-quality multi-cropped clay bricks. The difference is that there is a classification picking process and a post-screening iron removal process before the clinker is broken.

  On the basis of clay bricks, high alumina bricks change the Al2O3/SiO2 ratio and increase the Al2O3 content, so the refractoriness and high temperature mechanical strength are better than clay bricks. The chemical properties of high-aluminum bricks tend to be neutral, so acid-resistant and alkaline slags are more aggressive than clay bricks and silica bricks.
  Therefore, the parts of various thermal equipment that originally used silica brick or clay bricks can be replaced by high alumina bricks. Replacing clay bricks and silica bricks with high-aluminum bricks can increase the service life of thermal equipment.

Advantages of white and red high alumina refractory brick

1) High density and small thickness can increase the loading volume and promote the production capacity.

2) Low wear loss and long service life (it is 3-5 times compared with nature stone liner and 2-3times compared with rubber liner), which can reduce the installation times.

3) Main material is alumina which has no pollution to the grinding object.

4) Good thermal shock property

Quality Assurance
Annec Refractory is committed to high quality standards for all its products and services. With its thirst on State of the art technology at every level and a wide range of products, Annec Refractory can provide ideal solutions for the stringent requirement of the customer. Backed by decade of experience in different industries, and close association with customers, Annec Refractory will always bring new products which will give better life and value to the user.

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.

Packaging

Clay fire bricks will be packed by pallet , also with thermal shrinkage film, packing rope and edge protective paper, so that the brick will be sent to customer with no damage. We have special inspector to follow every order, records the producing and shipping detail, also take photoes before shipping your goods.
