Description

Technical Field

[0001] The utility model belongs to the technical field of sintering equipment, in particular to a molybdenum plate blank sintering device. Background Art

[0002] Molybdenum slab is the raw material for rolling molybdenum plates, molybdenum foils, and punching molybdenum discs. The raw material of molybdenum slab is generally pure molybdenum powder with an average Fisher particle size of 3.0-3.8μm. It is produced by powder metallurgy, and its production steps are as follows: first, the steel mold and rubber mold are designed according to the regular size required by the product, and the molybdenum powder is quantitatively loaded into the mold. The height of the molybdenum powder needs to be measured every time about 20% of the molybdenum powder is loaded. If the height of the molybdenum powder exceeds the calculated value, it is necessary to manually tamp the powder, lower the height of the molybdenum powder, and then load the powder until all the quantitative molybdenum powder is loaded into the mold. After the mold is sealed, it is placed in a cold isostatic pressing device for pressing. The pressed molybdenum compact is taken out of the mold and put into a medium frequency sintering furnace for sintering according to the designed process to obtain a molybdenum slab finished product, and finally the molybdenum slab is rolled.

[0003] Sintering furnace refers to a special equipment that makes powder compacts obtain the required physical, mechanical properties and microstructure through sintering. Sintering furnaces are generally heated by low-voltage and high-current graphite electric heating elements, and have the functions of degreasing (positive pressure degreasing and negative pressure degreasing), vacuum sintering, atmosphere sintering (hydrogen, methane, etc.), partial pressure sintering, pressure sintering and rapid cooling. Most of the existing sintering furnaces are only equipped with one opening for the placement and removal of molybdenum slabs. During operation, it is necessary to remove the sintered molybdenum slab from the support frame first and then put in the molybdenum slab to be sintered, and sinter several molybdenum slabs one by one in a cycle. However, there is a waste of time in the process of removing the molybdenum slab from the support frame and putting in the new molybdenum slab to be sintered, which reduces production efficiency.
