Description

Movable annular electroslag rod heat preservation and heating equipment Technical Field The utility model relates to the technical field of mechanical design and metallurgical heat treatment, in particular to movable annular electroslag bar heat-preserving and heating equipment. Background In petroleum, chemical industry, metallurgy and mechanical industry, a heating furnace is one of the most important devices, and can be used for heating materials with different purposes such as materials, metal workpieces, ceramic materials, alloy powder and the like to a specified temperature, and simultaneously heating workpieces and materials with various shapes such as forging pieces, casting pieces, powder, fragments and the like with different sizes, so that the heating furnace has wide application range and is widely applied to various industrial fields. The electroslag bar is an important material in the electroslag remelting process, and generally, the electroslag bar and the electrode are welded together in a welding mode and vertically placed into a remelting furnace to carry out the electroslag remelting process. In order to evaporate the water in the electroslag bar and remove more O, H and other unfavorable elements, the electroslag bar needs to be heated by a heating furnace for a long time. The conventional electroslag bar heating furnace adopts a high-temperature heat treatment box type resistance heating furnace, has sufficient heating space inside, can provide sufficient temperature, and realizes long-time heat preservation heating. But the appearance of the existing heating furnace is cuboid, the internal space of the heating furnace is square, when the cylindrical electroslag bar is placed in the heating furnace for heat preservation and heating, the space utilization rate is too low, and because gaps exist between the annular shape and the square shape, the heating furnace is identical with external air, so that the heating time is longer and the resources are more consumed. In addition, when the cuboid resistance heating furnace is used for heating the electroslag bar, the end to be heated of the electroslag bar needs to be moved to the furnace mouth of the resistance heating furnace, and then the whole electroslag bar is pushed into the resistance heating furnace through the horizontal trolley, so that the operation of the process is complex, and time and labor are consumed. The Chinese patent CN111504063A discloses a circular heating furnace with an upward opening, wherein the inner wall of the circular heating furnace is provided with different heaters, and the heating of different areas of the same workpiece is realized by PI0 control. The patent CN212227732U designs a barrel-shaped multi-layer heating furnace with an upward opening, and parts such as a screw cap, a positioning screw, a force application mechanism, a limiting plate and the like are arranged on the outer side of the barrel, so that the multifunctional barrel-shaped heating furnace capable of applying force from the outside (capable of pressing and heating a workpiece) is realized. However, the circular ring-shaped and barrel-shaped heating furnaces of the patent are suitable for workpieces or parts which are short in length, can be lifted from the upper part and vertically placed in the heating furnace, and for electroslag bars used in an electroslag remelting process, the length of the workpieces or parts is about 10m, and the vertical lifting is difficult to realize in the actual production process and the workpieces or parts are placed in the heating furnace with the opening upwards, so that the utility model designs a horizontal open movable annular resistance heating furnace applied to heating of the electroslag bars. Disclosure of utility model (One) solving the technical problems Aiming at the defects of low space and energy utilization rate, large occupied area, time and labor consumption in the heat preservation and heating process and the like of a cuboid box-type resistance heating furnace, the utility model provides movable annular electroslag bar heat preservation and heating equipment. (II) technical scheme In order to achieve the purpose, the utility model provides the technical scheme that the movable annular electroslag rod heat-preserving and heating device comprises a positioning base and a heat-preserving and heating furnace, wherein a screw hole is formed in the bottom of the positioning base, a supporting platform is arranged at the bottom of the positioning base through a bolt, and the heat-preserving and heating furnace is fixedly arranged at the top of the positioning base. Preferably, the heat-preserving heating furnace is an annular resistance heating type heat-preserving heating furnace, the outermost layer of the heat-preserving heating furnace is provided with a heat-resistant steel heat-preserving layer material, the secondary outer layer of the heat-preserving heating furnace is an aluminum silica
