Problems solved by technology

[0004] The existing production method has the following disadvantages: (1) The calcium carbide mound formed by the calcium carbide pot has a large volume and a long cooling time; (2) After the calcium carbide mound is cooled, it needs to be crushed, and the crushing process causes a certain powder loss; (3) Lifting It is inevitable that there will be bumps, which will shorten the service life of the calcium carbide pot. At the same time, the high temperature calcium carbide will also cause thermal stress in the calcium carbide pot, and it is easy to cause damage

Abstract

The invention provides a liquid calcium carbide molding mold. The mold comprises a cavity for receiving liquid calcium carbide, a sealed mold and a high temperature-resistant coating. The cavity is located on the mold. The surface of the cavity is coated with the high temperature-resistant coating for resisting high temperature calcium carbide thermal load. The liquid calcium carbide molding mold can realize liquid calcium carbide molding, finally produces a calcium carbide block or granule with a certain specification, shortens cooling time, prevents crushing-caused pulverization loss and improves a calcium carbide yield.

Description

technical field [0001] The invention relates to a mold for molding liquid calcium carbide, in particular to a mold for casting liquid calcium carbide into calcium carbide blocks or grains of calcium carbide of a certain size. Background technique [0002] The chemical name of calcium carbide is calcium carbide, and the molecular formula is CaC 2 , is the basic raw material of the organic synthesis chemical industry, and a series of organic compounds can be synthesized by using calcium carbide as the raw material, providing raw materials for industry, agriculture, and medicine. The main component of industrial calcium carbide is calcium carbide, its purity is about 70%-80%, and its melting point is as high as 1800°C-2200°C. [0003] In the existing calcium carbide production process, the finished calcium carbide is released from the calcium carbide furnace at regular intervals. A plurality of calcium carbide pots are placed around the outlet of the calcium carbide furnace, ...
