Description

Technical Field

[0001] The utility model relates to the technical field of working platforms, in particular to a working platform used for sintering molybdenum plugs. Background Art

[0002] Molybdenum plugs are made of molybdenum-titanium-zirconium-carbon alloy and are used to produce the core rod plugs of seamless steel pipe piercing machines. When used to pierce seamless steel pipes, molybdenum powder is used as the raw material to add rare earth materials, and then it is processed through mixing, molding, shape processing, and finally high-temperature sintering. After the shape processing, the plug blank should be placed in the medium frequency furnace for high-temperature sintering. The structure of the medium frequency furnace is the furnace lining, coil, yoke and water jacket from the inside to the outside.

[0003] When implementing this technical solution, there are at least the following defects: During the sintering operation, a layer of insulation is set outside the water jacket for heat preservation, but when placing the plug blank into the furnace lining, the staff generally stands between the water jacket and the insulation to operate, but due to the deep depth of the lining, it is difficult to operate. Therefore, we propose a working platform for molybdenum plug sintering. Utility Model Content
