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 reasons for the decline in the performance of high alumina bricks when we use high alumina refractory bricks?
The brick Pei boring and time. 6, Pei brick kiln installed between the brick and the brick Pei order, Pei and kiln top, kiln wall gap etc.. 7, high alumina brick kiln plan, and the lack of edges and corners of the scene should be avoided.
Q: What is the content of free silica in the refractory bricks of high alumina bricks?
In the meantime, the free silica content of silicon brick is as high as 90% above. Therefore, the most serious damage is silicon brick, followed by clay brick, high alumina brick, magnesia brick and so on.
Q: What are the characteristics of high alumina bricks?
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 high-temperature kilns and other energy consuming industries, such as chemical industry, electric power industry, etc.
Q: The difference between ordinary and diatomite brick refractory brick
To say the difference, the material is the biggest difference. There are diatomite brick density, compressive strength of small brick kiln belongs to the outer thermal insulation, and heavy refractory brick kilns for multi village in direct contact with the flame, high temperature resistance, good compressive strength, but no insulation. Hope to help you.
Q: How to distinguish the good or bad of the high aluminum brick?
The general high alumina bricks used in the steel, steelmaking, hot blast furnace, electric furnace, blast furnace, reverberatory furnace, rotary kiln lining of industrial furnace in China, mainly composed of a bauxite; sillimanite minerals (including kyanite, andalusite, sillimanite etc.); synthetic material, such as alumina synthesis of mullite, corundum, etc.. High aluminum brick has good quality, high refractoriness, long life and other characteristics, is the main use of refractory brick kiln products, commonly used units can not distinguish the quality and grade of high aluminum brick right in the procurement time, caused by the high prices to buy low grade products, thereby reducing the furnace life therefore, Zhengzhou's Sindh yuan refractory material factory in here is simple to introduce how to identify the quality when purchasing brick high alumina brick.Color: in the purchase of high alumina brick, first of all to see the color, high quality aluminum brick surface smooth, yellow color white, four sides smooth, no broken angle, no cracksWeight: the weight of a block of bricks to be called, according to the standard weight level, high aluminum brick weight of 4.5 kg. Two grade high alumina brick weighs 4.2 kg, three high aluminum brick weighs 3.9 kg, the same level, the same parameters can reach this standard can be regarded as high-quality high aluminum bricks, the opposite is not up to the weight that the quality is good, if there is a crack, four angle uneven, off angle phenomenon, then substandard products, some of the above points to help to the purchaser
Q: What does refractory consist of?
According to the chemical characteristics of refractory raw materials can be divided into acidic refractory materials, such as silica, zircon etc.; neutral refractory raw material, such as corundum, bauxite, mullite (acidic) (acidic), Ge (alkaline) iron and graphite; alkaline refractory materials, such as magnesite, dolomite, magnesium sand calcium sand.
Q: Is glass wool inorganic thermal insulation material?
The characteristics of glass wool, glass wool is the molten glass fibrosis, the formation of cotton like material, chemical composition of glass, is a kind of inorganic fibers. With good forming, small volume density, thermal conductivity, both thermal insulation, sound-absorbing performance, corrosion resistance, chemical stability.
Q: What is the difference between fireclay bricks and high alumina refractory bricks?
A neutral refractory with an alumina content of more than 48%. 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.
