Refractory Brick--Tradematt Refractory Manufacturer

Refractory brick masonry should be staggered brick joints, brick need to use refractory mud (dry puzzle with dry refractory powder) to fill, masonry process until put into production, to prevent masonry damp. In order to compensate for the volume expansion of the masonry after heating, the masonry needs to be designed according to the design and specification requirements. Refractory brick masonry wall, bottom, roof, pipe lining, brick lattice, combined brick masonry and expansion joints set aside. Masonry wall in accordance with its form is divided into two types of straight wall and curved wall. Straight wall before the masonry, the furnace floor should be the lowest level of the base surface leveling, on the basis of the furnace or steel structure according to the construction line. Measuring the vertical and horizontal center line and other reference line, in ensuring the size of the various parts of the furnace under the principle of accurately find the wall size line.

High alumina bauxite clinker is calcined bauxite. Generally,before Alumina Bauxite in the production of high alumina refractory bricks are  the calcined, get clinker, that is, barren material. With this High alumina bauxite clinker as the aggregate in the ingredients, can guarantee the volume stability of the refractory bricks and the size of the accurate. China's bauxite is mostly D-K type, in the calcination process to be decomposed dehydration, secondary mullite and re-crystal sintering three stages. The calcined mineral composition forms corundum, mullite and glass phase according to the ratio of Al2O3 and SiO2 in the raw material. High bauxite clinker is gray, light yellow and dark gray. It is mainly used to produce high alumina refractory bricks, can also be used to make fused corundum. The two major causes of sintering of high alumina bauxite are secondary mullite and liquid phase effects. The former depends on the Al2O3 ratio, which hinders the sintering effect; t...
