Composite pipe blank casting device and continuous casting method

Abstract

The invention relates to a composite metal material casting device and a continuous casting method, in particular to a composite pipe blank casting device and a continuous casting method. The casting device is structurally characterized in that an external control valve is arranged at an outlet end of an external heat-insulation furnace, an internal control valve is arranged at an outlet end of an internal heat-insulation furnace, the internal heat-insulation furnace is communicated with a crystallizer by the internal control valve, a core head is arranged at the front end of the crystallizer, a pouring pipe is arranged on the outlet end of the external heat-insulation furnace, the core head is positioned in the pouring pipe, and the crystallizer and the external heat-insulation furnace are respectively communicated with the pouring pipe; the pouring pipe is internally provided with a traction pipe, the inner end of the traction pipe is plugged with the core head, and the outer end of the traction pipe is connected with a tractor; and an electromagnetism generator is arranged outside the pouring pipe. The continuous casting method includes the steps of melting and heat insulation of alloy blanks, electromagnetic continuous casting of a composite pipe blank, cutting of the pipe blank, and quality check of the composite pipe blank. In the invention, the technique process and the equipment are both simpler, large-scale continuous production can be easily realized, and the production cost of the composite pipe blanks can be greatly lowered.

Description

technical field [0001] The invention relates to a casting device and a casting method of a clad metal material, in particular to a clad billet casting device and a continuous casting method. Background technique [0002] Clad metal material is a new type of composite material prepared by combining two or more metals with different physical, chemical and mechanical properties at the interface by using composite technology. Complementary effect" can make up for their respective deficiencies, and is widely used in the fields of automobiles, ships, aerospace, petrochemical, electronics and nuclear industries. [0003] At present, the methods for producing composite tube blanks mainly include: composite plate roll welding method, double-layer tube blank fixed pin extrusion method, centrifugal casting method, explosive composite method, centrifugal casting extrusion method, direct pouring method, etc. Among them, the composite plate coil welding method is to use the composite alu...

Problems solved by technology

[0006] One of the purposes of the present invention is to invent a casting device for multi-layer billet in order to overcome the defect that the composite interface is not firmly bonded and the yield rate is not high in the process of preparing the multi-layer billet by the existing composite billet production method. The device can produce multi-layer tube blanks with clear interface, smooth surface, and different components and properties of inner and outer layers.

[0007] The second purpose of the present invention is to invent a continuous casting method for multi-layer billets with simple process flow, low cost and continuous production in order to overcome the defects of discontinuity and low production efficiency in the existing composite billet production
