Abstract

The invention provides vacuum or gas protection smelting and casting equipment for continuous production. According to the specific technical scheme, a multi-door multi-furnace horizontal vacuum smelting chamber 1 is adopted; after a vacuum environment is provided by a vacuum unit or a protection gas is introduced, a material enters a smelting furnace 2 by virtue of a replacement chamber sealed charging device 4, wherein when a valve on the first floor is opened, and a valve on the second floor is closed, a material is charged; when the valve on the first layer is closed, and the valve on the second floor is closed, vacuumizing or protective gas replacement is carried out; when the valve on the first floor is closed, and the valve on the second floor is opened, a material enters a smelting furnace 2; after metal is heated and super-fused, a spot casting mechanism 3 is started, the molten metal is poured and injected into a current-limited casting pouring tundish 5; after one furnace of two devices in the vacuum smelting chamber is completely poured and cast, the other furnace takes turns to cast; a pressure detection device 6, an observation hole, an infrared temperature detector and the like are arranged on the furnace shell of the horizontal vacuum chamber; and the aim of continuous production can be achieved by means of alternating circulated charging for smelting and casting of multiple furnaces.

Description

technical field [0001] The invention relates to a vacuum or gas-protected smelting and pouring equipment, which can be continuously and efficiently produced, and is widely used in smelting under vacuum or gas protection, production of stainless steel and non-ferrous metal materials with low oxygen content and casting of mechanical parts, and low-oxygen Melting casting atomization preparation of metal powders with oxygen content. [0002] Background technique [0003] The smelting and casting technology under vacuum or gas protection is an important method to produce high-quality metal alloy materials and mechanical parts. The production method of this technology can ensure the stable composition of the smelted metal, less impurities, high purity, and low oxygen content. It has energy saving in the production process. Environmental advantages. [0004] Advanced atomization pulverization technology is the basis of modern powder metallurgy and product industrialization, a...
