Temperature control device of centrifugal casting machine

Abstract

The invention discloses a temperature control device of a centrifugal casting machine, which belongs to the technical field of detection control equipment and is used for detecting and controlling a casting temperature of the centrifugal casting machine. The technical scheme is as follows, the temperature control device comprises an industrial personal computer, a programmable logic controller (PLC) cabinet, a temperature measuring trolley, a temperature measuring pistol and a thermocouple, wherein the temperature measuring pistol is arranged on the temperature measuring trolley, the thermocouple is arranged in the temperature measuring pistol and is connected with the signal input end of the PLC cabinet, and the signal output end of the PLC cabinet is connected with a centrifugal motor. According to the temperature control device, the temperature measuring pistol extends into a casting cavity, temperature is measured by the thermocouple and is fed back to the PLC cabinet, the PLC cabinet controls the rotational speed and the centrifugal time of the centrifugal motor according to temperature deviation, so that the temperature of a roller working face is kept within a controlled range all the time, and adverse effect of temperature change on site production is avoided. The temperature control device has the advantages of real time, simpleness, convenience, intuition and high automatic degree, and can also be applied to temperature control of other production equipment in the casting industry.

Description

[0001] technical field [0002] The invention relates to a temperature control device for a centrifugal casting machine, which belongs to the technical field of detection and control equipment. Background technique [0003] In roll casting production, centrifugal casting machine is an important equipment in roll production, and its temperature control directly affects the product quality and yield of the entire roll. How to ensure that the temperature of the working surface of the roll is controlled within the normal range during the casting process is the key to production. In the prior art, manual temperature control is mainly performed according to the rotating speed of the centrifuge and the running time of the centrifuge, which depends on the operator's work experience, so the defect that the control accuracy depends on the subjective consciousness of the operator, resulting in the temperature of the roll forming The fluctuation is large, so that the process performanc...
