Device and method for manufacturing metal clad plates in way of continuous casting and rolling

A device for manufacturing metal clad plates in way of continuous casting and rolling, the device comprising first and second base material supplying equipment lines each including an uncoiler, a pinch roller, a shot blasting machine, a welding equipment, a welding pinch roller, an induction heating apparatus, and a guiding roller;

• wherein,
• a first base material strip (A) is transported through the uncoiler, the pinch roller, the shot blasting machine, the welding equipment, the welding pinch roller, the induction heating apparatus and the guiding roller of the first base material supplying equipment line;
• a second base material strip is transported through the uncoiler, the pinch roller, the shot blasting machine, the welding equipment, the welding pinch roller, the induction heating apparatus and the guiding roller of the second base material supplying equipment line, the first and second material strips are transported to a mould where the first and second base material strips and a molten steel are merged;
• the first and second base material strips enter the mould from above and pass through from below along inner walls of two sides of the mould, wherein the inner walls of two sides of the mould being sealed with side seal plates;
• a tundish for casting the molten steel is provided above the mould;
• the molten steel flows from the tundish into the mould and comes into contact with the first and second base material strips in the mould, so that a preliminary melt merging takes place;
• after the preliminary melt merging, the first and second base material strips (A) form composite slabs (B) and pass through the mould from below, and are cooled at a secondary cooling section with a cooling-spray located at an outlet of a lower part of the mould;
• a ski pass roll is provided after the secondary cooling section, and after the ski pass roll provided is a rolling mill for making composite slabs into composite strips (C) with a designed different size and specification;
• an on-line cooling equipment for the composite strips is provided after the rolling mill, a leveler is provided at an exit of the on-line cooling equipment;
• and the composite strips levelled by the leveler are then cut to a desired fixed length by a cut-to-length shear or coiled by a coiler.
