Temperature sorting device of intermediate-frequency heating furnace and control method thereof

Abstract

The invention provides a temperature sorting device of an intermediate-frequency heating furnace and a control method of the temperature sorting device of the intermediate-frequency heating furnace. The temperature sorting device of the intermediate-frequency heating furnace can automatically isolate and store blanks, excessively high or excessively low in temperature, output from a discharging opening of the intermediate-frequency heating furnace in the heating process and enables blanks meeting a heating temperature requirement to enter a forging furnace to be forged; and meanwhile, because the raw materials entering the forging furnace are in a temperature controlled environment, the use demand of a die is met, and the service life of the die is prolonged. The bottoms of an over-temperature discharging channel and a low-temperature discharging channel are both provided with storage boxes or conveyer belts, the storage boxes or the conveyer belts are matched with the over-temperature discharging channel and the low-temperature discharging channel, so that the blanks output by the over-temperature discharging channel and the low-temperature discharging channel can be automatically conveyed to corresponding positions, and it is not needed that the relevant blanks not meeting the temperature requirement are manually taken out at the over-temperature discharging channel and the low-temperature discharging channel; and in this way, efficiency is improved, and construction hidden danger is lowered.

Description

technical field [0001] The invention relates to the field of temperature separation of intermediate frequency furnaces, in particular to a temperature separation device for intermediate frequency heating furnaces. Background technique [0002] With the use of non-quenched and tempered steel, the requirements for the control of the heating temperature of the round steel billet are getting higher and higher, and the temperature fluctuation of the billet is difficult to control due to the influence of factors such as power grid, voltage, push material, and beat during induction heating. The temperature sorting of blanks can remove blanks that do not meet the temperature requirements and prevent them from flowing into the next process. In the prior art, the temperature of the billet after heating is usually determined by the worker’s visual inspection, and then the worker screens out the billets that do not meet the temperature requirements. Since the temperature is determined b...

Problems solved by technology

In the prior art, the temperature of the billet after heating is usually determined by the worker’s visual inspection, and then the worker screens out the billets that do not meet the temperature requirements. Since the temperature is determined based on experience after the worker’s visual inspection, the temperature judged by the worker may be different from the The actual temperature of the workpiece varies greatly. In addition, due to manual sorting, there is a phenomenon that workpieces with unqualified heating temperatures are transferred to subsequent processes, and precise control cannot be achieved.

[0003] Because the heating temperature of the intermediate frequency furnace is unstable, the mold loss is fast, and the scrap rate is high; the product size is not controlled, and the product size and appearance do not meet customer needs, resulting in high processing and manufacturing costs.
