Shaped refractory bricks are a type of refractory bricks with complex shapes. The customization of special-shaped refractory bricks must first communicate with the refractory brick manufacturer to determine the material, size, shape and kiln location of the required special-shaped brick. Common special-shaped refractory bricks include knife-shaped bricks, axe bricks, burner bricks and so on.
The models of knife-edge bricks are T-38 and T-39; that is, commonly known as large-knife bricks and small-knife bricks, their sizes are 230×114×65/55mm; 230×114×65/45mm, respectively. There are many textures of knife edge bricks, the common ones are high alumina and clay.
For special-shaped refractory bricks with sticky quality and high aluminum, the ratio of the external dimensions is within 1:5; the thickness dimension is 4}-95mm; the well has not many 2 concave corners (including arc-shaped concave corners) , Or have a 5. , A 75' acute angle, or with no more than 4 grooves; its mass is 2-15kg shadow bricks and 2-18kg high-alumina refractory bricks. For siliceous special-shaped refractory bricks, the ratio of the external dimensions is within the range of 1:5; the thickness dimension is 45-95mm; it has not many} = 1 four corners, or has an acute angle of 5D"-750, or No more than 2 grooves. For magnesia or magnesia-aluminum shaped refractory bricks, those that are not listed as ordinary magnesia or magnesia-aluminum refractory bricks are classified as special-shaped refractory bricks.
Refractory brick is referred to as fire brick. Refractory made of fire-resistant clay or other refractory materials. It is mainly used for building smelting furnace, and can withstand high temperature of 1580℃-1770℃. Also called firebrick. A refractory material with a certain shape and size. According to the preparation process, it can be divided into fired bricks, non-fired bricks, fused bricks (fused cast bricks), refractory and heat insulation bricks; according to the shape and size, it can be divided into standard bricks, ordinary bricks, special-shaped bricks, etc. It can be used as high-temperature building materials and structural materials for building kilns and various thermal equipment, and can withstand various physical and chemical changes and mechanical effects at high temperatures. For example, refractory clay bricks, high alumina bricks, silica bricks, magnesia bricks, etc.
Universal refractory bricks have the following characteristics:
1. Easy to work. The standardization of refractory bricks, that is, the use of general refractory bricks, brings great convenience to the design, manufacturing, supply, budget, and construction links.
2. Strong adaptability. General refractory bricks standardize refractory bricks and have strong adaptability. For example, T-3 bricks can be used in almost all kilns.
3. Can be used in conjunction with each other. Since general refractory bricks are standardized bricks, some of them can be used in conjunction with each other.
