The device and method for manufacturing metal clad strip continuously provided by the present invention, combines casting, rolling and heat treatment used for the single material manufacture with the continuous and large-scale manufacture method for the clad strip, greatly improves the productivity of clad strip. The present invention can be used for manufacturing single-sided or double-sided clad strips with different thickness specifications, wherein the base layer material or the clad layer material can be selected in a wide range, including carbon steel, stainless steel, special alloy steel, titanium, copper and the like. In the present application, continuous casting and rolling clad strip is implemented, which decrease the energy consumption and costs.

Device and method for manufacturing metal clad strips continuously

A side spray method for cooling a steel strip after hot rolling includes providing side spray devices behind multiple cooling sections on two sides in a width direction of a run out roller table of the steel strip after hot rolling. The side spray devices are staggered along the two sides of the run out roller table of the steel strip, the side spray devices include at least two spray units, each spray unit includes a spray tube and nozzles on the spray tube, the spray tubes being in parallel and vertically arranged along a running direction of the steel strip, and being movable along the running direction of the steel strip, covering ranges of the nozzles on the side spray devices are partially overlapped with each other, and a total spray coverage covering of nozzles covers a width of the run out roller table of the steel strip.

Side spray method for cooling the steel strip after hot rolling

A production apparatus for short-process metal composite plate manufacturing, the apparatus including a metal supply device including an uncoiler (), pinch roll (), shot blasting machine (), welding device (), welding pinch roll (), induction heating apparatus (), metal delivery machine (), two crystallization cooling rolls (), secondary cooling leveling roll (), rolling mill pinch roll (), rolling mill (), on-line cooling apparatus (), straightener (), and at least one of a dividing shear () and a recoiling machine (). Also disclosed is a production method for short-process metal composite plate manufacturing. The apparatus and method combine continuous casting, rolling, and heat-treating means for single material production with continuous and large-scale production of composite plate strips, and production efficiency of composite plates is sharply improved. Single-sided or double-sided composite plate production having different thickness specifications can be performed, the optional range of a base layer or cladding material is wide.
