Molybdenum crucible

The utility model provides a molybdenum crucible. The crucible is used for assisting in collecting lead-zinc metal and fluorine-containing slag high-temperature smelting volatile substances and is characterized by comprising a crucible body, the crucible body is of a cuboid hollow structure, a plurality of air inlet holes are formed in one end of the crucible body, the end, symmetrical to the endwhere the air inlet holes are located, of the crucible body is of a wedge-shaped structure, and an air outlet is formed in the end of the wedge-shaped structure; by means of the design, volatile matter can be sprayed out at a high speed, and the opportunity that the volatile matter makes contact with the furnace wall is reduced. The crucible disclosed by the utility model can be used for efficiently collecting high-temperature volatile substances of lead and zinc nonferrous smelting slag and fluorine-containing slag, can prevent impurity elements from participating in reaction, and is low in manufacturing cost and reu
