High Alumina Bricks manufacturing process is similar to much grog clay brick, the different is there are higher proportion of grog in ingredients that can reach 90~95%. Select and screening deironing before the grog crushed. Firing temperature is higher, as of Grade I &II high alumina bricks fired in the tunnel kiln is 1500~1600 ℃.Chinese production practice shows that select, grading and keep in storage high alumina grog before crushed. Adopt fine grinding methods calcined bauxite and mixed clay to improve product's quality.

Details:

1. Made by flint clay clinker and binder,through Crushing,Mixing,Shaping,Drying and high temperature Sintering.

2. Al2O3 content is 30%-48%,SiO2 content is 50%-65%,and a small number of alkali metals,alkaline earthmetal oxides TiO2,Fe2O3 etc.3.Working temperature:less than 1350°C.

Application:

It is widely used as a primary hot face refractory lining or as back-up insulation behind other refractory in furnace(such as carbon furnace, cracking furnace, heating furnace for oil refining, roller kiln, tunnel kiln.), flues, refining vessels, heaters, regenerators and similar high temperature industrial equipment.

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.
