Equipment and method for continuous casting and rolling of bimetallic composite plate and strip using single machine and two streams

Abstract

The invention discloses a device and method for thermometal composite board strip cast-rolling in a double flow and continuous mode through a single machine. According to the device, two main cast-rolling rollers of an ordinary stand type double-roller cast rolling machine are respectively and additionally provided with an auxiliary cast-rolling roller to form a cast-rolling-composite rolling union rolling mill provided with two monometallic composite strip blank cast-rolling units and a thermometal composite rolling area. The method mainly comprises the steps that cast-rolling forming of two different metal strips are independently and synchronously finished on the two monometallic composite strip blank cast-rolling units, and the different metal strips serve as blanks to be rolled and combined into thermometal board strips through the two main cast-rolling rollers. The device is simple and capable of greatly simplifying the technological procedures, and has the advantages of being capable of continuously working, high in yield and the like. The method is efficient and small in number of the procedures.

Description

Technical field: [0001] The invention relates to a processing equipment and a processing method for bimetal composite plate and strip. Background technique: [0002] With the development of modern science and technology, the requirements for the use of metal materials are no longer limited to a single mechanical property, but require metal materials to have comprehensive characteristics of both structure and function under multi-field or even extreme service conditions. Bimetal composite board is a layered composite material formed by compounding two metals with different physical and chemical properties through appropriate processes. By giving full play to their respective performance advantages, they can achieve comprehensive performance that cannot be achieved by a single metal board and save precious metals. Material. Composite materials with a variety of excellent properties can be prepared by selecting the properties of different metal layers such as corrosion resista...
