Steel shot quenching temperature control device

Abstract

The invention provides a steel shot quenching temperature control device and belongs to the field of steel shot production. The steel shot quenching temperature control device comprises a conveying belt and a quenching pool. Two or more sets of infrared temperature probes are arranged at the positions, where steel shots passing through, above the conveying belt, wherein one set of infrared temperature probes is arranged at the end, close to the quenching pool, of the conveying belt, and the rest of the infrared temperature probes are arranged on a conveying belt path. The conveying belt is surrounded by a temperature control chamber. The temperature control chamber is provided with a temperature control device body. The infrared temperature probes and the temperature control device body are connected with a control system. By arranging the two or more sets of infrared temperature probes, temperatures of the steel shots at different positions are obtained, the temperature change rate iscalculated, the constant temperature change can be set, the temperature of the steel shots entering the quenching pool is controlled, and the effects that the quality of the steel shots is stable andthe reject rate is low are achieved.

Description

Technical field [0001] The invention relates to the field of steel shot production, in particular to a steel shot quenching temperature control device. Background technique [0002] The current steel shot production line usually uses time to indirectly control the quenching temperature of the steel shot from the time the steel shot is rolled to the steel shot entering the quenching pool. Due to the difference in ventilation conditions and seasons in the workshop, the actual quenching temperature is different from the set quenching temperature. Certain differences, sometimes the quenching temperature is high, sometimes the quenching temperature is low, quenching cracking occurs when the quenching temperature is high, and the hardness of the steel shot is not up to the required when the quenching temperature is low. In some prior art, a temperature control device is added at the position before the steel shot falls into the quenching pool, but this design is obviously unreasonable....

AI Technical Summary

Problems solved by technology

[0002] The current steel shot production line generally uses time to indirectly control the quenching temperature of the steel shot from the time the steel shot is rolled out to the time when the steel shot enters the quenching pool. Due to the differences in the ventilation conditions of the workshop and the seasons, there is a difference between the actual quenching temperature and the set quenching temperature. There is a certain difference, sometimes the quenching temperature is high, sometimes the quenching temperature is low, quenching cracking occurs when the quenching temperature is high, and the hardness of the steel shot does not meet the requirements when the quenching temperature is low

In some existing technologies, a temperature control device is added at the position before the steel shot falls into the quenching pool, but such a design is also obviously unreasonable. The temperature at which the steel shot enters the quenching pool is changed by a momentary temperature change, and the temperature change does not change. easy to control
