Product Description:

refractory brick can be divided into three process: Raw material, molding, burning.Generally, refractory brick was molded by dry pressing. By means of mixing the material uniformity in proportion and aging mixture some time. Then, pour some powders into the module and dry pressing. After dry pressing, the adobe need to pushed in the drying kiln  to stoving or stay in the air  to drying. This progress will need about 3-5 days.  After this progress, then push the adobe into the tunnel furnace or shuttle  kiln to burning  around 1300C. This progress will be need about 5-7 days.

 After burning,  the brick will be packed in pallet and leave the factory.

Q:Why in the production of the brick to detect the volume density
Product quality control of silica brick.
Q:The production of brick, the ingredients of why join the waste brick?
The production of silicon material is added to the cause of waste brick:Preparation of silica brick pug, a certain amount of waste silica brick used to add ingredients, for the purpose of expansion and stress reduction products during firing
Q:The brick is mainly used in the place?
Also used for high temperature bearing part of hot blast stove and acid open hearth furnace.
Q:The United States of our brick anti-dumping duties?
At present of our brick anti-dumping rate is 73.10%
Q:The difference between clay refractory bricks and refractory brick in the application.
Brick bearing soft temperature and close to the melting point, high temperature strength, can be in high temperature (above 1400 degrees) under the condition of long-term use, but the anti alkali erosion ability, thermal shock stability is the worst, a scrap. The brick is generally used in the coke oven, glass kiln. Other industries basically do not use.
Q:What is the main material of silica brick
An acid refractory consisting mainly of quartz and square quartz and a small amount of residual quartz and glass.
Q:Semisilica brick, clay brick, high alumina brick and what is the difference?
The share of A12O3 and SiO2 is different
Q:The production of brick, the ingredients of why join the waste brick
Too much addition will reduce the refractory and mechanical strength, increase porosity, so the amount of waste brick should not be too much.
Q:Why will expand when heated brick
In the process of SiO2 drying, the four crystalline transformation points of 117, 163, 180~270 and 573 DEG C are found, among which the volume expansion caused by the 180~270 is the largest.
Q:Common bond brick
Lime should contain a lot of active CaO, I decompose CaCO3 and MgCO3 not more than 5%, Al2O3+Fe2O3+SiO2 no more than 5%. When the content of large particles, burned Ca-CO3 and over burned lime, the product produced caves, affecting the quality of products.
