Electromagnetic heating temperature control smelting furnace

Abstract

The invention discloses an electromagnetic heating temperature control smelting furnace which comprises a smelting furnace body and an electromagnetic heating temperature control system, wherein the smelting furnace body comprises a heating room; the electromagnetic heating temperature control system comprises an electromagnetic heating temperature control device, an electromagnetic coil and a temperature measurement sensor; the electromagnetic coil is surrounded outside the heating room; after alternating current (AC) high-frequency current is input by the electromagnetic heating temperature control device, an alternating magnetic field is generated so as to ensure that the heating room generates vortex flows to heat; the temperature measurement sensor is arranged in the heating room, connected with the electromagnetic heating temperature control device and used for detecting temperature in the heating room and acquiring data; and the electromagnetic heating temperature control device regulates the amount and the on-off of the AC high-frequency current according to the acquired data as required. The electromagnetic heating temperature control smelting furnace can save energy, protect the environment, exactly measure and control the temperature, save labor power and improve the safety.

Description

technical field [0001] The invention relates to an electromagnetic heating temperature control device, in particular to a melting furnace using the electromagnetic heating temperature control device. Background technique [0002] The traditional smelting furnace uses briquette, natural gas or oil to burn heat in the combustion chamber to reach the high temperature required for metal smelting. The disadvantages of this method are low energy utilization, serious environmental pollution, and greater safety hazards in heating with open flames. Hidden danger. [0003] With the widespread use of electric energy, the method of heating objects with resistive heating wires or electric heating coils has been widely used. Through these heaters, heat conduction conducts heat energy to heated objects or objects to be melted, because the above materials have Good heat conduction and heat preservation performance can realize heating function. However, due to the large thermal inertia of ...

AI Technical Summary

Problems solved by technology

At present, most melting furnaces use this kind of temperature measuring device. The detection method is relatively extensive, the precision is low, and it only has a display function, and cannot automatically adjust the temperature. When the temperature in the heating chamber is too high, it is necessary to manually adjust the power supply, which wastes manpower and causes It leads to unnecessary consumption of some energy, and does not solve the safety hazard caused by excessive temperature
