Problems solved by technology

[0002] A vanadium product company is currently the only manufacturer in the world that uses a large-scale tilting furnace to smelt ferrovanadium by electric aluminotherm. The tap hole diameter of its electric furnace is usually not more than 150mm, and the tap hole is often blocked during tapping, resulting in Frequent failures of gambling machines increase the labor intensity of employees
At the same time, the iron tapping time is too long, and it will cause iron inclusion in the slag after 6-8 minutes, which will affect the product quality and final vanadium yield. Therefore, it is necessary to improve the existing tilting furnace to adapt to modern high efficiency, low energy consumption, low strength, environmentally friendly production requirements

specific Embodiment

[0018] A vanadium product company currently only uses a large-scale tilting furnace to smelt ferrovanadium by the electric aluminothermic production status at home and abroad, and the taphole diameter of its electric furnace usually does not exceed 150mm, and the taphole is often blocked during tapping, resulting in a The frequent failure of the eye machine increases the labor intensity of the workers. At the same time, if the iron tapping time is too long for more than 6-8 minutes, it will cause iron inclusion in the slag, affecting product quality and final vanadium yield. The existing large-scale tilting furnace has been improved. The hole diameter of the existing tap hole was changed from 150mm to 200mm, and the corresponding matching transformation was carried out on the furnace body at the same time.

[0019] After the transformation of the taphole of the electric furnace, the tapping time can be effectively reduced, the quality of ferrovanadium products can be guaranteed...

Abstract

The invention discloses a tilting furnace, particularly discloses a tilting furnace for smelting ferrovanadium through an electro-aluminothermic process, and belongs to the technical field of design and manufacturing of metallurgical production equipment. The tilting furnace for smelting ferrovanadium through the electro-aluminothermic process is remarkably reduced in blocking frequency and more convenient in blockage clearing operation. The tilting furnace comprises a tilting furnace body and further comprises an open type tapping chute system, wherein the open type tapping chute system is arranged in the middle of the tilting furnace body in a downward-inclined mode.
