Fire resistant bricks are refractory products with a certain shape and size. Recently, many masonry problems about refractory bricks, such as the method of masonry of fire -resistant bricks, what masonry is used, etc.
Refractory fire bricks masonry
Regarding the method of masonry of refractory bricks, we are common in three main types and flat -building methods, side building methods, and vertical building methods. Most of the flat -building method is used for furnace walls, and there are a few at the bottom layer of the bottom of the furnace. In the fire -resistant material industry, the most common is the flattening method, which is the one -way method we often say. The ring -shaped masonry also often uses the flat -building method; the side -building method is mainly used in two parts: one is the bottom of the brick layer, such as the bottom of the furnace and the hot furnace; One is the vertical building method, which is also called standing building, mainly used for two parts: one is the top layer of the bottom of the furnace, such as the bottom of the flat furnace and the bottom of the blast furnace; the other is the working layer of the bottom of the furnace;
Different refractory bricks applications
Do not use fire resistance bricks to different kiln:
(1) Silicon brick is the main variety of acid refractory bricks. It is mainly used to build coke oven, as well as a variety of glass, ceramic, carbon scallion furnaces, fire -resistant tiles, and other load -bearing parts with fire tiles. It is also used in the high temperature load -bearing parts of the hot air furnace, but it is not suitable to be used in the heat work equipment with a high temperature of 600 ° C and a large temperature fluctuation.
(2) Clay bricks, it is a high -temperature, hot air furnace, heating furnace, power boiler, lime kiln, rotating kiln, ceramic and refractory brick firing tiles commonly used in kiln.
(3) Minerals with high aluminum fire -resistant bricks and high alumina bricks are composed of rigid jade, mullite and glass. The raw materials are natural stones of high aluminum alum and silicon lines, and there are also mixed with electric melting rigid jade, sintering aluminum, synthetic mullite stone, and clicks with aluminum and aluminum and clay. It produces more sintering methods. However, the product also has melting bricks, molten bricks, non -burning bricks and irregular refractory bricks. High aluminum refractory bricks are widely used in the steel industry, non -ferrous metal industry and other industries.
(4) Corundum brick, a refractory brick with corundum as the main thing, can be divided into sintering tiles and electric melting tiles. In addition to the above four common ones are alkaline -based refractory bricks:
(5) Magnesium refractory bricks, their products are divided into two categories: metallurgical magnesium and magnesium products. According to chemical composition and use, there are Martin Sand, ordinary metallurgical magnesium, ordinary magnesium bricks, magnesium silicon bricks, magnesium calcium bricks, magnesium carbon bricks and other varieties. Magnesium fire -resistant bricks are the most important products in alkaline and refractory bricks. High refractory resistance, good resistance to slag, and iron residue are an important high -level refractory brick. It is mainly used for flat furnace, oxidation turntable, electric furnace, and non -ferrous metal melting.
Summarize
The refractory fire brick of kiln is a seemingly simple, but complex process of masonry. The above we summarize is a common three types of masonry methods. Each kiln must be carefully summarized and carefully analyzed before the masonry. Only in this way can the refractory brick masonry suitable for composite standards.
