A Furnace Temperature Control System for Isothermal Normalizing Furnace

Abstract

The invention provides a furnace temperature control system for an isothermal normalizing furnace, which includes a feeding device, a preheating device, a spraying device, a secondary heating device and a controller, and the feeding device is arranged on one side of the preheating device , the spraying device is arranged on the other side of the preheating device, the side of the spraying device away from the preheating device is provided with the secondary heating device, the feeding device, the preheating device , The spraying device and the secondary heating device are equipped with transport devices, and the feeding device, the preheating device, the spraying device, and the secondary heating device are arranged in sequence to form a production line. By adopting the feeding device, the preheating device, the spraying device, the secondary heating device and the controller, the processing parts passing through the cabinet are preliminarily heated to ensure that the processing parts are further preheated.

Description

technical field [0001] The invention relates to the technical field of normalizing furnace production, in particular to a furnace temperature control system of an isothermal normalizing furnace. Background technique [0002] For large-scale forgings produced in nuclear power, chemical industry, machinery, boilers and other industries, their comprehensive performance is required to be higher and higher, so heat treatment is required, so large-scale heat treatment furnaces are equipped. [0003] For example, the prior art of CN105200203A discloses an integrated normalizing furnace, which has the problem of difficulty in feeding and discharging materials, and also affects the heating temperature of materials and the processing quality. Another typical furnace temperature control system disclosed in the prior art of CN207294848U, the instability of the temperature control process in the temperature control heating process, the controllability is poor and the temperature differen...

AI Technical Summary

Problems solved by technology

However, the above-mentioned scheme still has great imperfections, especially in that the rapid cooling of high-temperature workpieces still consumes a lot of energy, and the direct introduction of external cold air for rapid cooling cannot meet the different cooling requirements of different workpieces, and the workpiece The microstructure and mechanical properties are difficult to achieve the ideal state, and even affect the effect of air cooling and quenching in severe cases

[0004] In order to solve the common problems in this field, such as difficulty in feeding and discharging materials, poor temperature controllability and poor quenching effect, etc., the present invention is made
