Chain is the key component of coal mining and transportation machinery traction, which has a large demand and strict quality requirements, especially related to the safety of coal production. Heat treatment is an important part of production and manufacturing, its quality mainly depends on the quenching and tempering temperature control of the chain, and the tempering temperature control requirements are very accurate.

After the chain comes out of the water tank, it enters the tempering sensor at the original speed for secondary heating (differential temperature tempering). When the temperature in the middle of the chain link reaches 650 ℃, the chain leaves the sensor and is cooled naturally by air. The purpose of tempering is to improve the plasticity of the ring chain. Quenching inductor and tempering inductor are connected in series, and the chain is driven by a motor.

Compared with the common equipment, the powerful chain production equipment has more accurate control, stable welding quality and good mechanical properties. It can realize the functions of automatic identification of incoming parts, process parameter tracking and deviation from the given value correction. The mechanical performance of the ring chain is more stable, which can effectively reduce the labor intensity of employees and improve product quality. This kind of chain produced by the company brings a lot of benefits to the enterprise. When adjusting the chain, the staff should not only adjust the scale according to the frame chain, but also observe whether the front and rear toothed plates are in the same line with the chain with eyes. This inspection is very important.
