Description

Technical Field

[0001] The utility model relates to the technical field of molybdenum wire processing, and specifically discloses a hydrogen protection heating furnace for molybdenum wire processing. Background Art

[0002] Preparation of molybdenum wire: Molybdenum powder is mixed evenly with a certain proportion of other metal materials (such as sodium, potassium, aluminum, etc.), and a fluidizer, binder, etc. are added. It is pressed into shape, and then sintered and processed to finally obtain molybdenum wire. During the processing, a hydrogen-protected heating furnace is required to heat the molybdenum wire for annealing.

[0003] During the use of the existing hydrogen protection heating furnace, the furnace door needs to be opened and closed manually, which is laborious and time-consuming. After the furnace door is opened, tools are needed to take the molybdenum wire coil out of the furnace. Since the furnace is in a high temperature state, personnel need to perform high-temperature operations. At the same time, each time the molybdenum wire coil in the furnace is completely taken out, the molybdenum wire coil to be annealed can be loaded, resulting in low processing efficiency.

[0022] Among them, the first lifting mechanism 4 includes a first support 41 and a second support 42 arranged on the furnace body 1, and the first support 41 and the second support 42 are internally fixed with a first electric telescopic rod 43 whose top end is clamped on the inner side of the furnace door 6. The outer side of the top end of the first electric telescopic rod 43 is provided with a limiting plate 44 located on the outer side of the furnace door 6. The limiting plate 44 can be used to limit the furnace door 6, and at the same time, the furnace door 6 can be automatically opened and closed synchronously with the second electric telescopic rod 53 under the drive of the first electric telescopic rod 43, which is convenient to operate.
