Description

Technical Field

[0001] This utility model relates to the field of welding production equipment technology, specifically to a raw material mixing device for preparing submerged arc welding flux. Background Technology

[0002] With the rapid development of my country's heavy industry, submerged arc welding (SAW) has been widely applied in industrial production due to its advantages such as convenient operation, simple use, and no arc light. Therefore, my country's demand for sintered flux is increasing, and the focus of domestic SAW research and development has shifted to the development of SAW fluxes for different welding materials and special welding environments. With the development of modern industry, the thickness of plates used in welding processes is increasing, and most butt welds of thick plates require specific beveling according to specifications. Reducing the size of the beveling when welding thick plates can reduce the impact of welding heat input on the base material and save filler metal. Using a small beveling in SAW can save a significant amount of filler metal, and the heat-affected zone of the weld is narrower. Submerged arc welding often requires the use of flux, which is a granular welding material. During welding, it melts to form slag and gas, providing protection and metallurgical treatment for the molten pool. Submerged arc welding flux used for submerged arc welding.

[0003] Existing fluxes require mixing devices to combine various raw materials during processing and production. However, typical mixing devices directly stir and mix the raw materials, making it difficult for the materials at the bottom to mix with those at the top. This prevents the materials from being fully mixed and reacted, which is detrimental to flux production and reduces production efficiency and quality. In addition, typical mixing devices are prone to vibration and collisions with the ground during operation, generating a lot of noise and affecting the performance. Utility Model Content
