Problems solved by technology

[0002] When the metal is smelted, since the metal surface will be accompanied by water, oil and other impurities, when the metal is heated, the water and oil on the metal surface will splash. Therefore, it will cause safety hazards and endanger the operators. Healthy body
Therefore, before the metal is smelted, it is necessary to preheat the metal, which can effectively avoid the occurrence of the above problems. In the prior art, when the metal is preheated, the metal is placed in a common furnace body for direct heating. Not only will it cause uneven heating, but the temperature in the furnace body cannot be accurately controlled, which will cause uneven heating on the metal surface, which will have a certain impact on the quality of the metal

Description

technical field [0001] The invention relates to a high-efficiency preheating furnace, which belongs to the technical field of metal heating equipment. Background technique [0002] When the metal is smelted, since the metal surface will be accompanied by water, oil and other impurities, when the metal is heated, the water and oil on the metal surface will splash. Therefore, it will cause safety hazards and endanger the operators. In good health. Therefore, before the metal is smelted, it is necessary to preheat the metal, which can effectively avoid the occurrence of the above problems. In the prior art, when the metal is preheated, the metal is placed in a common furnace body for direct heating. Not only will it cause uneven heating, but the temperature in the furnace body cannot be accurately controlled, which will cause uneven heating on the metal surface, which will have a certain impact on the quality of the metal. Contents of the invention [0003] Aiming at the de...
