High-efficiency and energy-saving scrap metal smelting system

Abstract

The invention discloses an efficient energy-saving waste metal smelting system. The system comprises a medium-frequency electric furnace, a secondary dust removal moving smoke hood and conveying mechanisms. The output ends of the conveying mechanisms are connected with the medium-frequency electric furnace. The secondary dust removal moving smoke hood is arranged at the output ends of the conveying mechanisms and above a medium-frequency electric furnace body. The conveying mechanisms include two vibrating conveying mechanisms arranged side by side, and a crawler-type conveying mechanism. The crawler-type conveying mechanism is arranged between the rear portions of the two vibrating conveying mechanisms. A measuring and weighing mechanism is arranged at the input end of the crawler-type conveying mechanism. The efficient energy-saving waste metal smelting system is high in utilizing rate, good in stability, economic, environment-friendly, and capable of preventing pollution and guaranteeing safe running of smelting, waste metal can be measured and weighed during feeding, and therefore the smelting amount is controllable, potential safety hazards are reduced, and smelting efficiency is improved.

Description

Technical field [0001] The invention relates to the field of metallurgical smelting, in particular to a high-efficiency energy-saving scrap metal smelting system. Background technique [0002] Smelting is the melting and tempering of scrap metal materials and other auxiliary materials into a heating furnace. The charge will undergo certain physical and chemical changes at a high temperature (1300~1600K) in the furnace to produce crude metal or metal enrichment and slag. French metallurgical process. The smelting furnace is an important part of the smelting process. However, the existing smelting production line has the bottom of the smelting furnace utilization rate, and the temperature is too low to control, resulting in the defect of low production efficiency, and it is necessary to continuously add scrap metal to the smelting furnace during smelting Material, due to the limited capacity of the furnace, the amount of material added is limited. At present, the amount of materia...

Problems solved by technology

The smelting furnace is an important part of the smelting process. However, the existing smelting production line has a low utilization rate of the smelting furnace, and the temperature is too low to control, resulting in low production efficiency. In addition, scrap metal needs to be continuously added to the smelting furnace during smelting Materials, due to the limited capacity of the furnace, the amount of feeding is limited. At present, the amount of feeding to the furnace is uncertain. It is usually controlled according to the experience of the workers, so the amount of feeding cannot be well controlled. However, if the feeding If the amount is too small, the melting efficiency will be low, and if the amount of material added is too large, the load on the furnace will be too large, which may cause potential safety hazards

[0003] Moreover, due to the high melting temperature, the service life of the refractory material in the furnace is usually about half a month. After half a month, it needs to be removed and refilled. However, the refilled refractory layer still needs a certain period of air drying and molding. Therefore, the smelting work had to be stopped when the refractory material was replaced, resulting in low smelting efficiency and unable to meet production needs
