Introduction and selection of burner bricks

 

Burner brick is a kind of refractory brick used with the burner of high temperature kiln, such as blast furnace gas burner, special burner for lime furnace kiln, shaft furnace burner, regenerative heating furnace burner, etc. The shapes are different, and the burner bricks used do not have fixed specifications and sizes, and they often need to be customized in refractory manufacturers. The use of high-aluminum steel fiber castables can meet the working conditions of most burners.

The function of the burner brick is:

1.The fuel is heated to the ignition temperature in the burner brick, so that it is easy to ignite and burn quickly.

2.Keep a certain high temperature in the burner brick to stabilize the combustion process and avoid pulsation or fuel interruption.

3.The flame shape of the organization meets the requirements of the heating process.

4.To further mix the fuel and air. Therefore, the burner brick is an indispensable high-temperature resistant material for the burner of high-temperature industrial kilns.

Because the burner parts are mostly special-shaped, the high-pressure molding and firing method is not only costly, but also has a long production cycle. The number is too small and no manufacturer is willing to do it. Therefore, the burner bricks are mostly molded by casting, which is to choose a suitable refractory castable for casting, and the finished product after curing and baking. The requirements must meet the high temperature resistance, secondly, it must have higher strength, resistance to erosion, and the mixed erosion of natural gas and air, and finally the thermal shock resistance, that is, the performance of resistance to rapid cold and heat must be good.

Wanhao is a manufacturer who is specialized in designing various kinds of furnace and making refractory products for electric furnace, ladle, tundish, blast furnace, AOD furnace, IF furnace, etc.

Advantages and disadvantages of fire clay brick

图片
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 the a

The application of carburants

图片
Carburants are for casting iron. Carburants are added to steel, iron and carbon by carbon raw materials. High-quality carbon agent is essential for the production of high-quality steel auxiliary additives. At present, the vast majority of carburants are suitable for electric furnace smelting. Electric furnace smelting of the feeding method, the carbon agent should be with the scrap and other materials into the inside together, the addition of small doses can be added to the surface of the molten iron. But to avoid large quantities of molten iron to feed, to prevent excessive oxidation and the effect of carbon is not obvious and the cast carbon content is not enough. The amount of carbon agent added, according to the ratio of other raw materials and carbon content to set. Features 1.Absorption rate of it is up to 90% or more. 2.Improve the graphite form, increase the number of graphite, fine graphite, improve product mechanical properties, improve pro

Brief introduction of gunning material

  The EAF gunning material bears the same high temperature and harsh working environment as the repaired furnace lining during the smelting process. Therefore, in addition to high refractoriness, erosion resistance, erosion resistance, spalling resistance, etc., the EAF gunning mix must also be compatible with the repaired furnace lining. The lining has good adhesion. The gunning materials for electric furnaces include magnesia, magnesia-dolomite, magnesia-chromite, magnesia-carbon, magnesia-dolomite-carbon, etc., and some highly active seawater magnesia are used in the aggregate. To promote sintering and improve the density and strength of the gunning layer. In order to make the gunning material solidify quickly during the gunning operation and attach to the furnace lining at the same time, a small amount of additives are often added to the aggregate. 1.When adding Al, Mg and other low melting point metal powders for gunning, the oxidation heat of metal powder helps
