Description

Technical Field

[0001] The utility model belongs to the technical field of scrap steel processing, in particular to a scrap steel briquette preheating device. Background Art

[0002] Scrap preheating refers to the process of heating scrap to a certain temperature in front of the furnace to improve the melting and homogeneity of scrap steel; preheating scrap can reduce the gas content in molten steel, thereby reducing the viscosity and surface tension of molten steel, which is conducive to removing impurities such as oxides and sulfides in molten steel, and is conducive to the uniform distribution of molten steel, improving the utilization rate of molten steel and the quality of steel. Subsequently, the molten steel is solidified and extruded to form steel blocks;

[0003] At present, the scrap steel is preheated by controlling the preheating device, and the preheating device is composed of components such as a frame, a storage frame, a fan and an electric heating wire.

[0004] However, it still has the following disadvantages in actual use:

[0005] In the existing scrap steel preheating device, during use, the scrap steel is poured into the storage frame, and the fan and the electric heating wire are started to preheat the scrap steel inside the storage frame. However, the storage frame is an upper opening structure, so that the hot air can only enter the storage frame from a single direction, which reduces the efficiency of the scrap steel contacting the hot air, thereby reducing the scrap steel preheating efficiency, and is not conducive to uniform preheating of the scrap steel.

[0006] 2. In the existing scrap steel preheating device, during use, the scrap steel is poured into the storage frame, and the fan and the heating wire are started to preheat the scrap steel inside the storage frame. However, the scrap steel accumulated inside the storage frame is in a static device, resulting in a large shielding area for adjacent scrap steel, thereby causing incomplete preheating of the scrap steel and reducing the preheating quality of the scrap steel.

[0007] To this end, we provide a scrap steel briquette preheating device to solve the above problems. Utility Model Content
