Abstract

The invention provides a solid-liquid phase metal cast rolling compounding method and device capable of producing a novel metal composite strip through one time continuously by using multi-layer and various metal plates through liquid metal. On the basis of a plate strip cast rolling process, an open feeding nozzle is adopted, a pre-processed multi-layer metal strip penetrates through a cast rolling machine roll gap after soaking in metal melt in the feeding nozzle, the metal strip and the metal melt cooled to be in a semi-solid state and a solid state in a cast rolling area are rolled together, the metal melt is cured and attached to the metal strip, metallurgical bonding of two or more than two types of metal is formed, and the metal composite strip with the preset thickness is produced. The solid-liquid phase metal cast rolling compounding method and device has the advantages of being less in investment, low in production cost and energy consumption, good in product performance and wide in product range. The device comprises an uncoiling unit, a first dragging machine, a second dragging machine, an end shear, a splicer, a washing machine, a drying machine, a third dragging machine, a strip length and tension adjusting device, a cast rolling machine, (a heat preservation heating device, a hot continuous rolling machine), a shearing machine and a coiling machine production line.

Description

technical field [0001] The present invention relates to a solid-liquid phase metal casting-rolling composite method and equipment, more specifically, to a method for producing composite strips from solid-liquid phase metal using a casting-rolling machine, and an uncoiling unit used in the method , No. 1 haul-off machine, No. 2 haul-off machine, cropping shears, piecing machine, cleaning machine, dryer, No. 3 haul-off machine, strip length and tension adjustment device, casting and rolling machine, (insulation heating device, hot continuous rolling), Shearing machine, coiling machine production line. Background technique [0002] Metal composite strip is a new type of material that combines two or more metals with different properties through temperature and pressure. It can give full play to the performance characteristics of each component according to the design requirements, and replace many expensive metals with its high strength, wear resistance, anti-corrosion and oth...
