Embodiment 1

[0020] Taking the copper-aluminum composite board as an example, the method of the present invention is used to process the copper-aluminum composite board. Metal A is made of industrial red copper, and metal B is made of industrial pure aluminum. The size of the composite product is 2mm, and the copper-aluminum thickness ratio is about 1:3. The product width is 300mm. According to the thickness specification of the finished product, the roll gap between the main casting roll (left) 6 and the main casting roll (right) 8 is set to 2 mm, and the composite rolling reduction rate is 50%. Considering the reduction distribution relationship of two different metals, set the roll gap value between the main casting roll (left) 6 and the auxiliary casting roll (left) 16 to 0.94mm, and the main casting roll (right) 8 and the auxiliary casting roll (Right) The roll gap value between 13 and 3.06mm. The speed ratio of the main casting roll and the auxiliary casting roll is controlled to be...

[0022] Taking the copper-aluminum composite board as an example, the method of the present invention is used to process the copper-aluminum composite board. Metal A is made of industrial red copper, and metal B is made of industrial pure aluminum. The size of the composite product is 3mm, and the copper-aluminum thickness ratio is about 1:3. The product width is 350mm. According to the thickness specification of the finished product, the roll gap between the main casting roll (left) 6 and the main casting roll (right) 8 is set to 3 mm, and the composite rolling reduction rate is 60%. Considering the reduction distribution relationship of two different metals, set the roll gap value between the main casting roll (left) 6 and the auxiliary casting roll (left) 16 to 1.85mm, and the main casting roll (right) 8 and the auxiliary casting roll (Right) The roll gap value between No. 13 is 5.65mm. The speed ratio of the main casting roll and the auxiliary casting roll is controlled to...

Embodiment 3

[0024]Taking carbon steel-stainless steel composite plate as an example, adopt the method of the present invention to process carbon steel-stainless steel composite plate, metal A selects Q235 carbon steel for use, metal B selects 304 stainless steel for use, and its composite product size is 3mm, and thickness ratio is about 1 :1, the product width is 300mm. According to the thickness specification of the finished product, the roll gap between the main casting roll (left) 6 and the main casting roll (right) 8 is set to 3 mm, and the composite rolling reduction rate is 50%. Set the roll gap value between the main casting roll (left) 6 and the auxiliary casting roll (left) 16 to 3.15mm, and the roll gap value between the main casting roll (right) 8 and the auxiliary casting roll (right) 13 to 2.85mm . The speed ratio of the main casting roll and the auxiliary casting roll is controlled to be 0.9, the cooling water pressure in each casting roll is 0.5 MPa, and the casting machi...

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...
