Heating electric furnace with medium-frequency control touch screen

Abstract

The invention relates to the technical field of heating electric furnaces and particularly provides a heating electric furnace with a medium-frequency control touch screen. The heating electric furnace comprises a furnace body and a control cabinet, wherein the inner part of the furnace body is provided with a safe lining, and the outer surface of the safe lining is fixed with a coil; a cooling water pipe is mounted between the safe lining and a dry type material layer, and the dry type material layer is arranged on the inner side of the safe lining; the lower end of the furnace body is provided with a lower end cover, and the lower end cover is fixed to the upper surface of a piston rod in a hydraulic device; a water outlet of a double-power water pump mounted on the upper surface of a base is hermetically connected with a water inlet of the cooling water pipe through a pipeline; and the inner part of the control cabinet is divided into an upper layer, a middle layer and a lower layer, the touch display screen is arranged in the topmost layer, a silicon controlled rectifier tandem type medium frequency power supply and a main control unit are mounted in the middle layer, and a current monitoring ring and a water-cooled cable are arranged in the lowest layer. By mounting the silicon controlled rectifier tandem type medium frequency power supply in the control cabinet, the heating temperature of the heating furnace can be remotely controlled by using the touch screen.

Description

technical field [0001] The invention relates to the technical field of electric heating furnaces, in particular to an electric heating furnace with an intermediate frequency control touch screen. Background technique [0002] The intermediate frequency heating furnace is a power supply device that converts the power frequency 50HZ AC power into an intermediate frequency (above 300HZ to 1000HZ). The medium-frequency alternating current flowing in the induction coil generates high-density magnetic force lines in the induction coil, and cuts the metal material contained in the induction coil, generating a large eddy current in the metal material, which makes the metal itself generate a lot of heat , but the existing intermediate frequency heating furnace has a low level of automation, relying on manual operation to advance the metal billet for heating, and cannot cooperate with other automation equipment for intelligent networking, and the production efficiency is low; The tem...
