The sintering main exhaust fan is a key equipment in the sintering plant, and it is also the most energy-consuming equipment. Therefore, the position of the equipment in each sintering plant is very important. It runs normally or not, the length of its service life, the failure rate, and the fan performance (efficiency) are directly related to the production and quality of the sintering plant, and the economic benefits of the whole plant.

The magnetic levitation high-speed centrifugal fan adopts a direct drive structure of high-speed permanent magnet synchronous motor, which integrates centrifugal impeller and motor drive. Through the built-in displacement sensor, the displacement state of the rotating shaft is detected in real time. The collected signal is sent to the magnetic bearing controller for modulation and calculation, and the control current is generated. Then the current is input into the magnetic bearing coil to generate electromagnetic force, so as to adjust the suspension of the rotating shaft.

As the power central device of the CDQ system, the CDQ circulating fan plays a vital role. However, in both imported and domestic processes, the CDQ circulating fan is operated by a single machine without a spare fan, so the requirement for the stability of the fan is extremely high. Moreover, due to the high dust content, high hardness and high operating speed of the coke powder in the circulating gas, the requirement for the wear resistance of the fan is extremely high. Therefore, domestic CDQ circulating used to be imported products before, mainly supplied by German TLT and other foreign brands.

A combustion fan is a device used to increase the oxygen concentration during combustion. Its working principle is to inhale air through a fan, and a specially designed combustion aid device increases the oxygen concentration in the air. Then, the increased air concentration is injected into the burner and mixed with fuel for combustion, thereby improving combustion efficiency and reducing fuel consumption. In the industrial field, combustion fans are usually used in burners, furnaces and other equipment, which can increase the combustion efficiency of gas, oil and solid fuels by 20% to 30%, thereby significantly reducing environmental pollution and energy consumption.

The super wear-resistant fan is suitable for conveying gas with large dust content, and can adapt to harsh working conditions such as hard particles and high-speed flowing gas. The impeller and casing have undergone wear-resistant treatment, and the wear-resistant parts are made of imported brand wear-resistant composite plates. The composite plate is composed of easy to weld steel and wear-resistant and corrosion-resistant overlay, which has better wear resistance than CrC wear-resistant plates; Hard alloy has a higher density and higher resistance to fine particle wear; Higher carbide hardness results in higher wear resistance. In addition, wear-resistant ceramics and other methods can be used to enhance the wear resistance of overcurrent components.

The corrosion-resistant fan is suitable for corrosive environments such as weak acid and weak alkali, and is suitable for conveying corrosive and high-humidity gases. It has the characteristics of corrosion resistance and high temperature resistance. Its impeller and casing and other over-flow parts are made of stainless steel, with good durability and reliability; the shaft seal uses a carbon ring seal form, which is not only easy to replace and maintain but also achieves zero leakage of medium gas.

The high temperature fan is mainly used as a specialized fan for high-temperature operation, usually used to transport high-temperature gases. The operating temperature is generally between 150-500 ℃, and its material has high temperature resistance, high pressure resistance, and fan external insulation material to reduce heat transfer to the surrounding environment and protect the safety of operators and equipment. High temperature fans are widely used in steel smelting, glass manufacturing, cement production, petrochemical industry, heat treatment furnace, incinerator, drying equipment, power industry and other high temperature processes.

The dust removal fan is one of the important applications in the field of industrial environmental protection. It is a fan specially designed for industrial dust removal system, mainly used to transport gas containing dust or particulate matter. It is critical in a variety of industrial processes, especially those that produce large amounts of dust, such as cement manufacturing, mining, metallurgy, chemicals, power, and waste incineration. Its working principle is to transport the gas with high dust content to the supporting dust collector, and filter out the dust and harmful gas through the filter material, so as to reduce the emission of dust and harmful gas, improve the working environment of workers and meet the requirements of environmental protection. When the dust removal fan is placed at the front end of the dust collector, the dust-containing gas has a wear effect on the fan impeller and the shell, and the key parts of the fan are usually treated with wear resistance.

Ring cooler is an important part of the sintering process in the iron and steel industry. It is used to cool the high-temperature sintered pellets produced by heat treatment in the iron and steel production process. There are many types of ring coolers, and the commonly used one is the single head ring cooler. The equipment is composed of multiple rotors and stators. The high-temperature sintered pellets discharged one by one enter the static cooling air duct of the stator from top to bottom through rotation, and the ring cooling fan is used for forced air cooling and natural air cooling for refrigeration. Finally, the processed pellets are transported to the downstream production line.
