Specail Shape of High Alumina Brick

$High Quality Best Price High Alumina Insulated Refractory Fire Bricks$

Q: What are the reasons for the spalling of refractory bricks in the production of lime kiln?: In the course of the production of lime kiln, the local block of refractory brick is a very dangerous signal. It is suggested that you stop the kiln to prevent the collapse of a large area. Lime kiln is the main equipment for the production of limestone kiln and rotary kiln is two, with the growth of calcium carbide lime kiln industry, iron and steel industry, the construction industry to the amount of limestone has become the main production equipment, and refractory bricks became the heart of lime kiln.

Q: Introduction of high alumina brick: Made from alumina or other raw materials of high alumina content; formed and calcined. High thermal stability, fire resistance above 1770. Slag resistance is good, used for masonry steel smelting furnace, glass furnace, cement rotary furnace lining.

Q: What are the common thermal insulation materials for thermal conductivity?: The single organic insulation material should be the best polyurethane in the field. In accordance with the production process can be divided into on-site foam polyurethane and factory prefabricated rigid foam polyurethane board. The scene is polyurethane foam isocyanate and polyol to cool (polyether or polyester) two components as the main raw materials with additives, the on-site spraying construction with thermal insulation and waterproof function of the rigid foam material.

Q: What are the high temperature refractory mortars made of?: Siliceous mud, mineral composition and chemical composition is similar with silica, excellent corrosion resistance, water glass slurry, drying shrinkage, but also can be used for bonding fiber products, sealing furnace wall.

Q: What are ordinary bricks, refractory bricks, hollow bricks?: Light yellow or brownish. The utility model is mainly used for laying smelting furnaces, and can withstand high temperature between 1580 DEG C and 1770 DEG C. Also called brick. Refractory material of a certain shape and size. According to the preparation process can be divided into bricks, brick, electric melting brick (Rong Zhuzhuan), the refractory insulating bricks; according to the shape and size can be divided into standard brick, brick, brick and other specific type. It can be used as high temperature building materials and structural materials for construction kilns and various thermal equipments, and can undergo various physical, chemical and mechanical changes at high temperature. For example, refractory clay brick, high alumina brick, brick, brick etc..

Q: What are the requirements for refractory materials in heat treatment furnace?: The structural strength of high temperature is evaluated by loading softening point. Load softening point is that under certain pressure (2 kg/ cm 2 = 0.2MPa) under the condition of heating rate to heating, measured the sample deformation (deformation for the original sample 0.6%) temperature. This temperature is called the softening point of the refractory. Sample size is Phi 36 x 50mm.

Q: What is the difference between high alumina brick and clay brick?: There must be a difference. They vary in color from the amount of aluminum, the weight, the temperature, and the color. For example: 75 high aluminum and 43 clay bricks, 75 single weight 4.5kg or more. 43 3.65kg or so, the use of temperature 75, high aluminum in about 1520, 43 of brick 1430 or so, the color of 75 pan white, 43 of the Loess color. In short, the difference is great.

Q: Use of high alumina refractory bricks?: High alumina brick refractory than clay refractory bricks and brick refractory degree are higher, up to 1750~1790 DEG C, which belongs to high-grade refractory materials.

Q: Which thermal shock stability of clay brick and high alumina brick is good?: The product has the advantages of high temperature, little creep, strong corrosion resistance and good thermal shock resistance, and is suitable for large and medium-sized hot blast stoves.Thermal shock stability is much better than clay brick.

Q: What is the difference between fireclay bricks and high alumina refractory bricks?: First of all, there is a difference in the material, one is clay, and one is high aluminum.Also known as clay brick brick, is a man-made small bulk building, clay brick clay (including shale, coal gangue powder) as the main raw material, through mud processing, molding, drying and roasting, solid and hollow.
