White ash furnace refractory brick is a kind of refractory material commonly used in high-temperature industrial furnaces, and its use temperature range is wide, generally between 700-1800. When choosing refractory bricks for white ash furnace, we need to consider comprehensively according to the specific use temperature, kiln structure, fuel and other factors. This article will analyze the types, properties, and other aspects of refractory bricks for white ash furnaces to help you choose the most suitable product.
First of all, let's learn about the types of refractory bricks for white ash furnaces. Refractory bricks for white ash furnaces are mainly divided into clay bricks, high-alumina bricks, magnesia bricks, silica bricks, etc. Among them, clay bricks are the most common one, and its main component is kaolin, which has good thermal shock resistance and wear resistance, but has poor high temperature resistance, and is generally suitable for furnaces with lower temperatures. High-alumina bricks are made of alumina as the main raw material, which has excellent high temperature resistance and thermal shock resistance, and is suitable for high-temperature furnaces. Magnesia brick is made of magnesia as the main raw material, which has extremely high temperature resistance and thermal shock resistance, but is high, and is generally used in furnaces with special requirements. Silica brick is made of silica as the main raw material, which has good high temperature resistance and thermal shock resistance, but has poor acid resistance and is generally not suitable for acid furnaces.
Secondly, let's learn about the performance of refractory bricks in white ash furnaces. The performance of refractory bricks in white ash furnace mainly includes refractoriness, thermal shock resistance, wear resistance, slag erosion resistance, etc. Refractoriness refers to the ability of a refractory material to maintain its integrity at high temperatures, and generally speaking, the higher the refractoriness, the better the temperature resistance. Thermal shock resistance refers to the ability of a refractory material to resist cracking when the temperature changes dramatically, and generally speaking, the better the thermal shock resistance, the longer the service life. Wear resistance refers to the ability of refractory materials to resist frictional wear, and generally speaking, the better the wear resistance, the longer the service life. Slag erosion resistance refers to the ability of refractory materials to resist slag erosion, and generally speaking, the better the slag erosion resistance, the longer the service life.
Finally, let's take a look at the ** of refractory bricks for burning white ash furnaces. The refractory bricks of white ash furnace are affected by various factors such as their types, specifications, and production processes. Generally speaking, clay bricks are lower, high-alumina bricks are moderate, and magnesia bricks and silica bricks are higher. In addition, the same type of white ash furnace refractory bricks produced by different manufacturers may also have certain differences. Therefore, when choosing white ash furnace refractory bricks, we need to consider comprehensively according to our actual needs and budget.
To sum up, the use temperature range of white ash furnace refractory bricks is wide, and the choice of which type of product needs to be comprehensively considered according to the specific use temperature, furnace structure, fuel and other factors. When choosing refractory bricks for white ash furnaces, we also need to pay attention to their performance and other factors to ensure that we can choose the best quality products for our needs. At the same time, we also need to pay attention to the regular inspection and maintenance of the refractory bricks of the white ash furnace to ensure their normal use and prolong their service life.
Which is better to use high temperature 7 800 degrees for burning white ash furnace refractory bricks?Today, I will sort out the information about this party for you, I hope it will be helpful to you.
Refractory bricks Nowadays, the rapid development of various refractory industries has promoted the development of the refractory products industry, with the increasing demand for refractory products for various refractory, wear-resistant, thermal shock and other positions. Fire bricks have made great progress in performance, points and characteristics. Inquiries from similar shops are inevitable. Which is better to use high temperature 7 800 degrees for burning white ash furnace refractory bricks?There are many types, and the specifications and lengths of bricks also vary.
Here is a summary of the questions about shaped refractories** and what information users need to provide. Inquire about shaped refractories** can directly explain the material of the required bricks to the manufacturer in the form of ** or fax, and the general fire bricks are mainly divided into: high alumina shaped refractories, clay refractory bricks, lightweight refractory bricks, magnesia chrome bricks, fused bricks, silica bricks, etc.
For fire bricks, there is no doubt that people know that there are many kinds of brick numbers in brick products, and the proportion of raw materials between them is also different, which determines the application part and fire resistance of bricks. It is impossible for the stereotype refractory manufacturers to directly mark the price, after all, the competition in the same industry is still quite fierce.
However, no matter how the use effect and performance of refractory products are improved, user needs are only concerned about two issues: whether you are shaping refractories to make the agreed shape refractories.
The grade or specific gravity of the required bricks is stated in the demand (physical and chemical indicators are better);For example, high-alumina bricks are divided: first-class high-alumina bricks (aluminum-specific proportion 70%), second-grade high-alumina bricks (aluminum-specific high-alumina bricks (aluminum-specific gravity 60%), clay bricks (aluminum-specific proportion 42%), etc. Specify the specifications and length of fire bricks, generally in the form of drawings, general index shaped refractories, manufacturers have stock, special-shaped shaped refractories on demand.
Which is better to use high temperature 7 800 degrees for burning white ash furnace refractory bricks?It is relatively simple, because the calcination temperature is not high, and the high temperature does not exceed 1300. Therefore, the refractory brick lining used is generally high-alumina refractory brick. Lightweight insulating bricks can be used for insulation. The thickness of the brickwork of the white ash shaft kiln is larger. The thickness of the bricklaying of the 250m3 white ash shaft kiln can reach 1000mm, while the thickness of the bricklaying of the rotary kiln is only about 200mm. In addition, refractory concrete can also be used. In recent years, special high-alumina refractory bricks have also been used in the calcination zone of the shaft kiln, such as wear-resistant and high-alumina refractory bricks. To sum up, there are the following types of refractory bricks for white ash calcining kiln: high-alumina refractory bricks, clay bricks, lightweight insulation bricks, refractory concrete, fillers, etc.
The technical conditions and specifications of the refractory bricks used can be referred to the following technical standards:
1) Clay bricks GB 4415—
2) Lightweight insulation brick - GB 3994 -
3) High alumina refractory bricks - GB 2988 -
5) Refractory concrete—GB 3712—
