Continuous casting forming equipment and process method for electromagnetic ejection filling core of cladding material

Abstract

The invention relates to continuous casting forming equipment and a process for an electromagnetic ejection filling core of a cladding material, belonging to the field of the continuous casting processing in metal material. The equipment provided by the invention comprises upper and lower temperature control crystallizers, a temperature measuring instrument, a metal temperature control furnace of the core, an outer metal temperature control furnace, a filling core tube, an electromagnetic pump, a secondary cooling device, a limiting device, a pressure sensor and a recession device, wherein the upper and lower temperature control crystallizers and a metal liquid filling core tube of the core are arranged on the same axis along the continuous casting direction; the electromagnetic pump is installed outside the upper and lower temperature control crystallizers and assembled on the same axis with the upper and lower temperature control crystallizers; the upper end of the metal liquid filling core tube of the core is connected with a metal temperature control crucible of the core, and the lower end is inserted into outer metal liquid; the outer metal liquid and the metal liquid of the core are isolated through the metal liquid filling core tube of the core; the outer metal liquid is cooled to form an outer metal tube; the metal liquid of the core is poured into the outer metal tube through the metal liquid filing core tube of the core; and a composite blank is ejected out by exerting the pressure through the electromagnetic pump. The invention eliminates cracks and vibration marks which are easy to occur in a common continuous casting blank, can continuously cast the cladding material once, obtains a composite interface of high quality and has the advantages of low production cost and high efficiency of subsequent processing.

Description

technical field [0001] The invention belongs to the field of continuous casting processing of metal materials, and provides equipment and technology for electromagnetically ejecting and core-filling continuous casting of cladding materials. 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.

Problems solved by technology

Due to the vibration marks, the dynamic fit gap of the crystallizer vibration, the wear of the mold, the discontinuity of the solidification process, and the tensile stress in the composite billet, this method is not suitable for the preparation of precise composite billets, such as the outer diameter Φ15 ~ 20mm or less, Composite blank with outer wall thickness of 1.0-3mm
