Fine forming equipment of coating material which is pressed, ejected, core-filled and continuously casted and technique

Abstract

The invention relates to a fine forming equipment of a coating material which is pressed, ejected, core-filled and continuously casted and a technique, belonging to the pressure processing field in metal materials. The equipment consists of an upper crystallizer, a lower crystallizer, a temperature measuring instrument, a core metal temperature control furnace, an outer metal temperature control furnace, a core-filling tube, a pressure cover, a supporting plate, a secondary cooling device, a limiting device, a pressure sensor and a conceding device, wherein an outer metal crystallizer and a core metal liquid core-filling tube are arranged on a same axis along the continuous casting direction; the upper end of the core metal liquid core-filling tube is connected with a core metal temperature control crucible and the lower end thereof penetrates deeply in the outer metal liquid; the core metal liquid core-filling tube is used for isolating the outer layer and the core metal liquid to form an outer layer metal mold core; and the core metal liquid is casted. The pressure cover is connected with the edge end of the supporting plate and the inner side of the supporting plate is connected with a lower temperature crystallizer; an outer metal casting blank is ejected by applying pressure through the gas in the pressure cover. The invention eliminates cracks and oscillation marks which occur in common continuous casting blanks easily, can continuously cast the coating material by one time, and obtain a high-quality composite interface; and the follow-up processing production has low cost and high efficiency.

Description

technical field [0001] The invention belongs to the field of pressure processing in metal materials, and provides equipment and a process for fine forming of clad materials by pressure ejection, core-filling continuous casting and continuous casting. Background technique [0002] The development of new materials has been promoted due to the stringent requirements on materials due to the development of high technology. Composite materials can play the synergistic effect of their constituent raw materials, and at the same time have a large degree of freedom in material design, so they are developing rapidly. They are not only more widely used in the scope of application, but also improved in decoration, electrical conductivity, thermal conductivity, corrosion resistance and mechanical properties, more reasonable material selection and lower manufacturing costs, and the integration of structure and function has become an in-depth Potential advantages for development.

AI Technical Summary

Problems solved by technology

Due to vibration marks, dynamic fit clearance of mold vibration, wear of mold, discontinuity of solidification process, and tensile stress in slab, this method is not suitable for preparing precision continuous casting slabs, such as outer diameter Φ15 ~ 20mm or less , wall thickness 1.0 ~ 3mm continuous casting tube billet
