refractory

Our company mainly produces refractory bricks, with advanced technology, strong technical force, detection equipment. Refractory brick production has five steps:

Borrow the earth. Soil baked bricks are used from ancient earth beneath the surface of the Earth to take two feet deep. The soil color layer is slightly deeper than the overburden, which formed between 80,000 and 80,000 years ago. At that time, the Earth's warm and humid climate, rich biological role in this period of the formation of soil soft and sticky, is a good refractory brick material.

2. Excavate the clay and let the sunshine, snow and rain freeze and erode in the open-air accumulation process for about half a year to decompose and loosen its interior, and then hand-crush and sieve, leaving only fine pure soil .

3. Add water to the soil, wet it, and then repeatedly refining, or use cattle power trample to make it mud, the human mud and refining through the need for five to six times, the process plays a vital quality The role of brick.

4. The soil into the wood block mode, after compaction, scraping the excess sludge with a wire to form a blank. Blocking, the need to sprinkle a layer of fine sand in the wood floor, in case of mud and ground adhesion.

5. After stripping the bricks, you need to dry the sun visor in the sun, so as not to be exposed to the bricks, cracks and deformation.
