The blast furnace centrifugal fan is mainly composed of a static part and a rotating part. The static part consists of the casing, the air inlet pipe, the bearing, the sealing device, the fan expander, the return device and the air outlet pipe. The rotating part consists of the rotor and the impeller mounted on the main shaft of the rotor, the thrust plate, the balance wheel, etc.

Blast furnace smelting is an important process in iron and steel production, and its blast furnace smelting equipment consists of blast furnace body, blast furnace dust collector, blast furnace blower, blast furnace hot blast stove, molten iron tanker, etc.

In recent years, due to the inferior, poor, miscellaneous and refractory iron ore resources in my country, fine grinding must be carried out in order to improve the utilization efficiency of iron ore, which can result in the majority of domestic iron concentrates with fine particle size.

As one of the blast furnace raw material supply equipment, the sintering machine also plays a very important role. The sintering machine trolley is mainly responsible for charging, igniting, sintering on the track and discharging sinter at the tail.

The centrifugal fan is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine.

In the sintering production process of the belt sintering machine, the sealing effect of the main fan and the tightness of the contact between the bellows and the trolley will directly affect the utilization rate of the energy supplied by the sintering machine.

Blast furnace cement refers to the cement made of blast furnace slag. Slag, also known as granulated blast furnace slag, is a glassy material formed when the slag melted by blast furnace ironmaking is quenched without crystallization. Its main components are calcium oxide, silicon oxide and alumina. It has high potential activity. Under the action of activator, it can be combined with hydration to form hydraulic cementitious material.

Horizontal continuous casting of steel is a new technology with broad development prospects. It has the advantages of simple equipment, low investment and convenient operation. In addition, the tundish is directly horizontally connected with the mold, which can effectively prevent the secondary oxidation of molten steel (prevent the liquid steel and injection of ladle and tundish

After more than 30 years of efforts, continuous cast steel has gradually replaced ingot mold casting. Continuous casting slabs with thickness of 150 ~ 250mm are widely used in various countries to produce plates. In the 1980s, continuous casting technology has made a breakthrough. At present, the continuous casting technology that can pour thinner slabs and higher pouring speed to make the production capacity have economic scale is developed

According to the type of charging equipment, furnace capacity, raw materials, fuel conditions and ratio, determine the batch weight, charging line, loading sequence, distributor rotation angle and working procedures of bell less furnace top rotary chute: multi ring distribution, spiral distribution or single ring distribution, opening of material flow control valve, working procedures of furnace throat guide plate, etc.
