Transverse magnetic induction heating temperature uniformity automatic adjusting system and method

Abstract

The invention provides a transverse magnetic induction heating temperature uniformity automatic adjusting system and method. The transverse magnetic induction heating temperature uniformity automatic adjusting system comprises a transverse magnetic induction heater (1), strip steel, a temperature line scanner (3) and a transverse magnetic induction heating control cabinet (4). The transverse magnetic induction heater (1) is connected with strip steel; the temperature line scanner (3) is fastened and connected above the strip steel behind the transverse magnetic induction heater (1); and after the strip steel passes through the transverse magnetic induction heater, the temperature line scanner scans the temperature of the strip steel in the width direction, and the temperature value is recorded. The transverse magnetic induction heating control cabinet (4) is connected with the transverse magnetic induction heater (1). By adopting the automatic temperature uniformity adjusting system for transverse magnetic induction heating, the problems that in the strip steel heating process, the strip steel is overburnt and overcooled, the temperature in the width direction is uneven, and the normal continuous production is affected due to slow response of manual heating parameter adjustment are solved.

Description

technical field [0001] The invention relates to the technical field of transverse magnetic induction heating temperature adjustment, in particular to a system and method for automatically adjusting temperature uniformity of transverse magnetic induction heating. Background technique [0002] At present, in order to solve the problem of uneven temperature of strip steel heated by transverse magnetic induction, it is usually used to adjust the width of the coil, or adopt a new hexagonal coil and other inductor design stages to solve the problem of uneven temperature at the exit of the plate. When the temperature uniformity in the width direction of the strip exceeds the allowable range, the operator will adjust the power supply parameters and sensor-related process parameters. This method responds slowly, and the operator’s adjustment process is complicated. Mistakes in the middle of the operation may cause the strip Local overheating and other issues.

[0002] At present, in order to solve the problem of uneven temperature of strip steel heated by transverse magnetic induction, the problem of uneven temperature at the outlet of the plate is usually solved by adjusting the coil width or adopting a new hexagonal coil and other inductor design stages.

When the temperature uniformity in the width direction of the strip exceeds the allowable range, the operator will adjust the power supply parameters and sensor-related process parameters. This method responds slowly, and the operator’s adjustment process is complicated. Mistakes in the middle of the operation may cause the strip Local overheating and other issues
