  According to production process, fire clay brick is divided into machine made brick and handmade brick. According to structures, fire clay brick is divided into solid brick and hollow brick, and hollow brick can be divided into load-bearing brick and nonbearing brick. Fire clay brick is made at different shapes according to different using requirements. Advantages of fire clay brick： 1. Fire clay brick is environmentally friendly and belongs to resource recycling bricks, so we can rest assured use fire clay brick. Fire clay bricks won’t be harmful to our health. 2.Fire clay brick has advantages of fireproof and heat insulation. Used clay brick can be used as concrete so that to save a lot of resources. 3.The price of fire clay brick is not as expensive as that of other fire bricks. Light weight brick is more expensive than fire clay brick. Besides, fire clay brick is very cheap and very durable 4. Fire clay brick has good moisture-proof function, it also has th...

  Cold crushing strength Cold crushing strength is the ultimate load per unit area of dense shaped refractory products can withstand without damage at room temperature. The cold crushing strength of pressure-resistant refractory products has a great impact for the production, transportation and use performance, so higher cold crushing strength is better. The high crushing strength indicates that the processed quality is good, structure is uniform, and well sintered. High temperature crushing strength High-temperature crushing strength is the refractory products under the specified high temperature conditions, the unit area can withstand without damage. The high temperature crushing strength of refractory products determines the use scope, which is an important basis for the use of refractory materials . High temperature crushing strength indexes are also meaningful to unshaped refractories, especially refractory castables and fire-resistant plastic materials. So the hig...

Refractory brick is made of refractory clay or other refractory raw materials, it is in color light yellow or brown. Refractory brick is a kind of refractory materials with a certain shape and size. According to manufacture methods, it can be divided into sintering brick, non-sintering brick, fused cast brick, and refractory insulating brick; according to shape and size, it can be divided into standard brick, common brick, and special shape brick. Refractory firebricks can be used as furnace building material and structural material for building furnaces and various thermal equipments, and it can withstand various physical and chemical changes and mechanical effects at very high temperatures. For example, refractory clay brick, high alumina brick, alumina carbon brick, magnesia brick, etc. Refractory brick is one of the most widely used products in refractories, and do you know its characteristics? 1. Chemical composition: The main components determine refractory brick...
