Introduction of Common Refractory Brick Specifications

1. General purpose refractory brick

Refers to straight brick, side thick wedge brick, vertical thick wedge brick, vertical wide wedge brick and arch foot brick used for straight brick laying and radiant brick laying for refractory brick lining of thermal equipment such as industrial furnaces and kilns.

2. Straight bricklaying

Refers to straight wall with flat surface and flat bottom brickwork.

3. Radiant Bricklaying

Brickwork with radius, central angle and arc-shaped surface. Radial bricklaying according to the central angle is divided into thrust arch with central angle less than 120 °, semicircular arch with central angle equal to 180 ° and circular ring bricklaying with central angle of 360 °. According to the type of bricks used for matching masonry, it is divided into single wedge-shaped brick brick ring with one wedge-shaped brick masonry ring, mixed brick ring with wedge-shaped brick and straight brick masonry ring, and double wedge-shaped brick ring with two wedge-shaped brick masonry ring.

4. Flat build

The large face of the brick is placed on the horizontal bricklaying base surface bricklaying method.

5. Side building

Bricklaying method where the side of the brick is placed on the horizontal bricklaying base surface (or arch tire surface).

6. Vertical masonry

Bricklaying method (also known as vertical masonry) in which the end face of the brick is placed on the horizontal bricklaying base surface (or arch tire surface).

7. straight brick

Only because of the straight parallel six-sided brick body composed of three dimensions of length A, width B and thickness C, the pressure surface formed by length and width is called the large surface, the brick surface formed by length and thickness is called the side surface, and the brick surface formed by width and thickness is called the end surface. There are many kinds of general refractory brick specifications, 8. there is also a simple is according to the pore points, respectively, 13 holes, 20 holes, 4 holes, 6 holes, 8 holes, resulting in pores with the rate of heat flow out is not the same. Of course, this is also one of the cases, refractory bricks each time under the same temperature expansion and contraction of the situation must be the same.

There are many kinds of refractory brick raw materials, which are mainly divided into six categories: soil, stone, sand, ore, powder and others.

One of the raw materials, soil: bauxite, kaolin, clay, diatomite

The second raw material, stone: fluorite, kyanite, andalusite, forsterite, vermiculite, mullite, pyrophyllite, chlorite, dolomite, sillimanite, magnesium aluminum spinel, silica

The third raw material, sand: ceramic sand, zircon sand, quartz sand, magnesia

The fourth raw material, ore: chrome ore

Five raw materials, powder: metal aluminum powder, silicon powder, metal silicon powder

Refractory brick raw material six, other: asphalt, graphite, phenolic resin, perlite, floating beads, sialon, corundum, silicon sulfate, silicon carbide, water glass, silica sol, boron carbide, calcium aluminate cement, nitriding materials, shale ceramsite, alumina, alumina sol, zirconia, etc.
