Automatic temperature regulating system for constant temperature furnace

Abstract

The invention discloses an automatic temperature regulating system for a constant temperature furnace. The automatic temperature regulating system comprises a temperature detection unit, a controller, a temperature display unit, a parameter setting unit, a theoretic heating temperature estimating module, a deviation comparing controller and a warning unit, wherein the controller is used for controlling a heating device of the constant temperature furnace according to the temperature information detected by the temperature detection unit; the deviation comprising controller is used for comparing and analyzing the temperature which is detected by the temperature detection unit in real time with the actual heating temperature calculated by the theoretic heating temperature estimating module; the warning unit is controlled by the controller; the temperature detection unit comprises a plurality of temperature sensors and mean solving modules, wherein the temperature sensors are arranged in the center and a plurality of positions on the inner side of the circumferential wall in the constant temperature furnace; and the mean solving modules are respectively connected with the temperature sensors. The automatic temperature regulating system has the advantages of reasonable design, good use effect and high intelligent degree and is easy and convenient to operate; the detected temperature can accurately reflect the actual temperature in the heating furnace in the current state; the heat treatment effect of processed workpieces can be effectively ensured; and the automatic temperature regulating system has remarkable economic and social benefits.

Description

technical field [0001] The invention relates to a heating furnace temperature adjustment system, in particular to an automatic temperature adjustment system for a constant temperature furnace. Background technique [0002] In the metallurgical and mechanical heat treatment industry, the smelting temperature, annealing and normalizing temperature, quenching and tempering temperature of metal materials have a decisive influence on the structure, mechanical properties and processing performance of metal materials, so the heating temperature of the heating furnace must remain constant. The temperature automatic adjustment system used in the existing heat treatment furnace is generally a fixed value single parameter automatic adjustment system composed of temperature sensing elements, base instruments and actuators, because the heat treatment process requires the furnace temperature to be controlled at a stable value, so Usually, the control scheme that keeps the adjusted quanti...
