Pulley PM Parts

Product Description

Compared with natural ore, sintered ore has many advantages, such as high iron content, large porosity, easy reduction, less harmful impurities, alkaline flux, etc., and the requirements for raw materials are not as strict as pellet ore, so sintering Widely used in iron production.

According to different sintering equipment and air supply methods, sintering methods can be divided into:

(1) blast sintering. Such as sintering pot, blow on the ground (stack burning). This is the local method of sintering in small smelters, which has been gradually eliminated.

(2) Ventilation sintering.

1) Continuous ventilation sintering, such as belt sintering machine and ring sintering machine;

2) Intermittent ventilation sintering can be used not only on fixed sintering machines, such as disc sintering machines and box sintering machines, but also on mobile sintering machines, such as walking sintering machines.

(3) Sintering in flue gas. Such as rotary kiln sintering and suspension sintering.

When there is no mixing stockyard, the technological process of sintering production generally includes: raw material acceptance, storage, preparation of flux and fuel, batching, mixing, distribution, ignition and sintering, hot ore crushing, hot ore screening and cooling, cold ore screening Separation and crushing, bottom material laying, storage and transportation of finished sintered ore, return ore storage and other process links. When there is a mixing stockyard, the receiving and storage of raw materials and fuels are carried out in the stockyard, and sometimes the screening of flux and the preparation of fuel are also carried out in the stockyard. Whether to set up hot ore sieve should be determined according to specific conditions or test results and after comparing technical and economic indicators. The on-machine cooling process does not include hot ore crushing and hot ore screening. The kiln hood is an intermediate that connects the hot end of the kiln with the next process in the process (such as a cooler). The burner and the air required for combustion enter the kiln through the kiln hood. Refractory materials are built in the kiln hood. There is a sealing device between the head cover and the rotating cylinder, which is called the kiln head seal. The kiln tail cover is an intermediate that connects the cold end of the kiln with the material pretreatment equipment and the flue gas treatment equipment, and is filled with refractory materials.
