Descaling equipment for high temperature billet in hot extrusion process of seamless steel pipe

Abstract

Disclosed is scale removing equipment of high temperature preform body in a seamless steel tube hot extrusion process. An inner circle scale removing tossing drum is connected with an inner circle scale removing speed reducer. A guide linkage seat is connected with a vertical shaft bracket and a tossing drum heightening hydraulic cylinder. A tossing drum transversely moving hydraulic cylinder is connected with the bottom of the vertical shaft bracket. An outer circle scale removing mechanism of the preform body is characterized in that an outer circle scale removing tossing drum is connected with an outer circle scale removing speed reducer, the outer circle scale removing speed reducer is installed and connected on a lifting stand frame, a swing arm mechanism is installed and connected on the lifting stand frame, the swing arm mechanism is connected with the outer circle scale removing tossing drum and an outer circle scale removing tossing drum heightening hydraulic cylinder, and a jockey pulley of a power speed reducer is connected and installed on the outer circle scale removing tossing drum in a matched mode. The scale removing equipment of the high temperature preform body in the seamless steel tube hot extrusion process is simple and practical in structure, and suitable for the simultaneous scale removing of an inner circle and an outer circle of the high temperature preform body on a production line of hot extruding a seamless steel tube with a big caliber or other calibers.

Description

technical field [0001] The invention relates to a high-temperature billet descaling device in a seamless steel pipe hot extrusion process in the technical field of seamless steel pipe hot extrusion manufacturing machinery. Background technique [0002] With the continuous development of the seamless steel pipe manufacturing industry and the continuous progress of manufacturing machinery, the technology of high-temperature billet descaling equipment for seamless steel pipe processing and manufacturing equipment, especially large-diameter (outer diameter φ700-φ1800mm) seamless steel pipe hot extrusion process The requirements are also getting higher and higher. In the known technology, in the existing seamless steel pipe hot extrusion process, the high-temperature billet needs to be heated to about 1200°C, and the billet is directly extruded, and the surface scale is serious, which affects the surface quality of the product after processing and forming. The existing high-temp...
