Ring cooling fan


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.

CDQ circulating fan

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.

Combustion fan

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.
