Technical Field

The invention relates to the field of equipment for manufacturing welding materials, in particular to a granulating device for non-melting welding flux.

Background

Submerged arc welding is an important efficient welding method and is widely applied. Submerged-arc flux is classified into melting flux and non-melting flux as consumable materials of submerged-arc welding. The production and use of the melting flux are gradually limited due to the high energy consumption and environmental hazardAnd (5) preparing. Therefore, with the rapid advance of industrialization in China, the dosage of the non-melting flux keeps a steady growth trend. Non-melting fluxes are further classified into bonding fluxes and sintering fluxes according to the sintering temperature. The bonded flux and the sintered flux are indispensable in the production process, and the granulation mode of the non-melting flux in China is almost disc granulation. Under the disk granulation mode, the frictional force that the disc rotation produced drives the wet material of welding flux and walks the pitch arc and move to the eminence, after reaching the peak, the wet material of welding flux falls under the action of gravity, and with the wet material that rises and the fender that encloses at disc edge collision extrusion each other, so after repeating many times, the wet material of welding flux finally is collided the extrusion and becomes closely knit ball form granule. Since the path of travel and residence time of the flux wet in the disk are not well controlled, the loose ratio (mass of free loose powder per unit volume) of flux produced by disk granulation is often relatively high, typically 1.20g/cm³Above, the loose loading ratio of the welding flux with high alloy content can even exceed 1.50g/cm³. The excessively high flux loose loading has a significant adverse effect on submerged arc welding manufacturability, causes various defects such as no spreading of weld bead metal, undercut inclusion of weld bead edges, cratering of weld bead surfaces and the like, and seriously damages the inherent quality of weld bead metal. In contrast, the apparent ratio of foreign well-known brand flux is generally 1.0g/cm³Left and right, the weld bead wetting angle is little, spreads the broad, and the surface is level and smooth, does not have defects such as indent, undercut, inclusion sediment. Therefore, the reduction of the loose ratio of the flux by improving the granulation mode is an important way for improving the quality of the flux.
