Cooling device for diameter measuring instrument

Abstract

The invention relates to a cooling device for cooling a diameter measuring instrument. The device comprises a circulating cooling water mechanism and an air blowing mechanism which are arranged in an area, through which wires to be measured pass, of the diameter measuring instrument. When the air blowing mechanism blows the air outward, the flowing air discharges the heat of the wires, and the effect of cooling the diameter measuring instrument is achieved, so the air blowing mechanism is just an air cooling mechanism; and the circulating cooling water mechanism also achieves the effect of a thermal insulation barrier and prevents the heat of the wires from being transferred to the diameter measuring instrument. Thus, the heat in a wire traveling area cannot be transferred to the diameter measuring instrument after double cooling of air cooling and water cooling and thermal insulation, and then the diameter measuring instrument is naturally at lower temperature, namely approximately in a room temperature environment, so that the steady work of the diameter measuring instrument is facilitated and equipment aging is also avoided. Meanwhile, the air blowing of the air blowing mechanism can also blow dust, impurities and water vapor in the diameter measuring instrument out of the diameter measuring instrument, and also blocks dust, impurities and water vapor outside the diameter measuring instrument so as to prevent the dust, the impurities and the water vapor outside the diameter measuring instrument from entering the diameter measuring instrument; therefore, the cleanness and dryness of an inner cavity of the diameter measuring instrument are ensured.

Description

technical field [0001] The invention relates to a cooling device for keeping detection instruments and equipment at a relatively low temperature to ensure normal operation of the equipment, in particular to a cooling device for a diameter measuring instrument used in a steel rolling process. Background technique [0002] In metallurgy, especially in the iron and steel industry, it is necessary to conduct on-line and real-time diameter detection of the wire and bar at the inlet and outlet of the rolling mill during the rolling process, so as to set the working parameters of the rolling mill according to the size of the incoming material or to detect the wire and bar. In case of size deviation, the rolling mill can be adjusted and controlled in time to ensure the rolling yield. [0003] However, because steel rolling is in a high-temperature, high-humidity, and high-dust environment, it is very difficult to seal, clean, and cool the caliper for on-line detection of the wire ro...

Problems solved by technology

[0003] However, because steel rolling is in a high-temperature, high-humidity, and high-dust environment, it is very difficult to seal, clean, and cool the caliper for on-line detection of the wire rod diameter, and the detection reliability and equipment stability of the caliper are difficult. ensure

More especially, the newly rolled wire rod itself is in a high-temperature state. When it passes through the caliper, the cooling and cooling requirements of the caliper are extremely high. However, there is no reliable cooling device in the prior art, which leads to the caliper Working at high temperature for a long time, firstly, the stability of the equipment is poor, and the detection accuracy is difficult to guarantee; at the same time, the equipment is easy to age, which increases the production cost
