Abstract

The invention belongs to the technical field of metallurgical equipment, and particularly provides a hot extrusion die on-line heating device and a using method. The hot extrusion die on-line heating device comprises an extrusion die, a die pressing cylinder and a pressing block, the pressing block is installed at the bottom of the die pressing cylinder, the hot extrusion die on-line heating device further comprises a die holder, a temperature detection device, a heater and a heating control unit, the middle part of the die holder is connected with the extrusion die, the inner interior of the die holder is connected with the heater, the heater is electrically connected with the heating control unit, the pressing block is connected with the temperature detection device, and the pressing block is located above the extrusion die. The problems that in the prior art, on-line heating cannot be achieved in the hot extrusion process, it cannot be guaranteed that the temperature of a die is controlled within the process range, and the production efficiency is affected are solved. According to the device and the method, the on-line heating function of the hot extrusion die can be achieved, meanwhile, the temperature of the extrusion die can be monitored online, the extrusion production quality is guaranteed, the replacement frequency of the extrusion die is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of metallurgical equipment, and in particular relates to an online heating device for a hot extrusion die and a use method thereof. Background technique [0002] In the hot extrusion process, the quality of the mold and the temperature of the mold are crucial to the yield of the extruded product, especially in the process of extrusion preparation of high-performance wide-width industrial plates and composite materials. [0003] At present, the extrusion molds are all heated offline in the mold heating furnace to the process temperature, and then placed in the extrusion equipment for extrusion production. Due to the limitations of the distance between the mold heating furnace and the extrusion machine and the technical level of the operators, this process is time-consuming and laborious. And there is no guarantee that the mold temperature is controlled within the process range. During extrusion production, d...
