Cylinder type induction heating furnace with insulating cabinet

Abstract

The invention relates to a cylinder type induction heating furnace with an insulating cabinet, belonging to the technical field of oil pipe heating equipment. The cylinder type induction heating furnace comprises a heating cabinet and the insulating cabinet, wherein the heating cabinet consists of a spiral cylinder and an induction coil, the insulating cabinet consists of an insulating cabinet body, an insulating layer, a thermal-protective layer, a resistive heating mesh belt, an oil pipe insulating retention channel and a bearing post, wherein the oil pipe insulating retention channel is arranged at the upper part of the insulating cabinet body, and the resistive heating mesh belt, the thermal-protective layer and the insulating layer are sequentially arranged outside the oil pipe insulating retention channel; and the bearing post is arranged at the left side of the oil pipe insulating retention channel, and a movable baffle is arranged at an outlet of the right side of the oil pipe insulating retention channel. By prolonging the insulating time of a heated oil pipe through the insulating cabinet additionally arranged, the carbonization consistency of the inside and outside of the oil pipe can be ensured, impurities on the surface of the oil pipe can be removed thoroughly, the heating cost of the oil pipe can be effectively lowered, and the operation and maintenance are simple and convenient. The problems that the existing cylinder type induction heating furnace has no insulating facilities so the inside and outside of the oil pipe are unclean due to sintering of impurities, impurity removal effect is poor and carbonization of the inside and outside of the oil pipe is inconsistent.

Description

technical field [0001] The invention relates to a cylindrical induction heating furnace with an incubator, belonging to the technical field of oil pipe heating equipment. Background technique [0002] The barrel-type induction heating furnace for quenching, tempering, and removing impurities for the oil pipe has the characteristics of good power saving effect, less burning loss, low energy consumption, and no pollution to the environment. At present, ordinary resistance mesh belt heating furnaces are gradually being phased out and become a new generation Metal heating equipment. However, because the existing drum-type induction heating furnace is not equipped with oil pipe insulation facilities, there are defects that the impurities on the surface of the oil pipe are not sintered cleanly and the cooling speed of the treated oil pipe is too fast, resulting in inconsistent carbonization of the inside and outside of the oil pipe, and the effect of removing impurities on the sur...
