Problems solved by technology

However, it still has the following disadvantages: the validity of on-site experience is only limited to specific workshops and products, and the repeatability of the heating process is poor
The process of numerical simulation method is complicated, the consumption time is too long, and the calculation model needs to be properly simplified during the simulation, and the accuracy of the simulation results is low, which reduces the production efficiency and increases the production cost
In addition, the field experience or numerical simulation method is mainly used to study the environmental conditions in the furnace, and does not make real-time adjustments to the heating process according to the heating of the heated workpiece, resulting in a decrease in the effective heating rate and heating quality

Abstract

The invention discloses a control device for heating temperature of a cylindrical workpiece, which comprises a control device body, the control device body is provided with a bracket supporting a plurality of workpieces to be heated, and the plurality of workpieces to be heated are evenly and symmetrically distributed among In the heating furnace, temperature-measuring thermocouples are installed at the positions where the bracket is in contact with multiple workpieces to be heated, a temperature-measuring camera is installed on the inner furnace surface of the heating furnace, and left-side The burner and the right burner, the heating furnace is electrically connected with a computer that collects and processes the heating temperature signals of multiple workpieces to be heated and controls the heating. The present invention abandons the traditional control method that takes the temperature in the furnace as the object, The temperature adjustment and control is directly targeted at the workpiece to be heated, which greatly improves the control accuracy of heating and the effective heating rate and heating quality of the workpiece to be heated.

Description

technical field [0001] The invention relates to the technical field of heat treatment, in particular to a device and method for controlling the heating temperature of a cylindrical workpiece. Background technique [0002] The regenerative heating furnace can use the waste heat of the flue gas to preheat the fuel during the heating process. It has the advantages of low fuel consumption, relatively uniform temperature in the furnace, high heating quality, and environmental protection. It is widely used in the heating process of various workpieces middle. Because the regenerative heating furnace involves a dynamic continuous reversing process during the combustion process, it will cause fluctuations in the temperature of the upper part of the furnace; a viscous turbulent layer is formed at the bottom of the workpiece to be heated, which is not conducive to heat exchange around the workpiece to be heated; the burner airflow and furnace The mutual interference of the backflow ga...
