Production apparatus and method for preparing metal clad plate in short process

A short process for preparing a metal clad plate, comprising the following steps:

• uncoiling a base material strip (A) having a thickness of 2-25 mm with an uncoiler (1) and sending it with a pinch roll (2) to a shot blasting machine (3) for surface cleaning;
• while sending the base material strip having a thickness of 26-100 mm directly to the shot blasting machine (3) by the pinch roll (2) for surface cleaning;
• then welding the shot-blasted base material strips from a head to a tail with a welding device (4), or directly entering a next process;
• sending the welded base material strip with a welding pinch roll (5) to an induction heating equipment (6) for heating, wherein the induction heating equipment is filled with nitrogen or argon protection atmosphere, a heating temperature is 100° C. to 1200° C., and a heating rate ranges from 1˜50° C./s;
• injecting molten base metal contained in a flow distributor (7) between two molding cooling rolls (8) to form a molten metal pool (B), and blowing argon on a surface of the molten metal pool to reduce oxidation of the molten metal, wherein a temperature of the molten metal is 30˜165° C. higher than a melting point of the base material strip, and a base material strip (A) heated by a previous step enters the molten metal pool between the two molding cooling rolls along the two molding cooling rolls at a speed of 0.1˜30 m/min to melt and clads a base layer and the base material strip to form a cladding slab (C);
• after coming out of the molding cooling roll, the cladding slab (C) enters a secondary cooling leveling roll (9) to be cooled again and makes a surface of the cladding slab (C) deformed and flattened, wherein cooling water is introduced into the inside of the secondary cooling leveling roll or the cladding slab (C) is cooled by spraying water on all sides;
• the cladding slab after further cooling and flattening is sent to the rolling mill pinch roll (10), and then enters the rolling mill (11) to be rolled into the cladding strip (D) with different thicknesses of 0.5˜100 mm.
