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

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

• sending a base material strip with a pinch roll to a shot blasting machine for surface cleaning;
• sending the base material strip with a welding pinch roll to an induction heating equipment 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 between two molding cooling rolls to form a molten metal pool, and blowing argon on a surface of the molten metal pool to reduce oxidation of the molten base metal, wherein a temperature of the molten base metal is 30˜165° C. higher than a melting point of the base material strip, and a base material strip heated by the induction heating equipment 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;
• after the cladding slab comes out of the two molding cooling rolls, using a secondary cooling leveling roll to cool the cladding slab again and make a surface of the cladding slab deformed and flattened, wherein cooling water is introduced into an inside of the secondary cooling leveling roll or the cladding slab is cooled by spraying water on all sides;
• and
• sending the cladding slab after cooling and flattening by the secondary cooling leveling roll to a rolling mill pinch roll;
• and
• using a rolling mill to roll the cladding slab into a cladding strip with different thicknesses of 0.5˜100 mm.

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

• using a flow distributor to cast molten steel between two molding cooling rolls to form a molten metal pool, wherein the flow distributor is arranged above the two molding cooling rolls;
• using two base material supply devices to convey base material strips, wherein the two base material supply devices are arranged on both sides of the two molding cooling rolls, and the two base material supply devices each include an uncoiler, a pinch roll, a shot blasting machine, a welding device, a welding pinch roll, and an induction heating equipment;
• using the two molding cooling rolls to respectively receive the base material strips conveyed from the two base material supply devices so that each of the base material strips is immersed into the molten metal pool along a corresponding molding cooling roll of the two molding cooling rolls and then rolled into a cladding slab;
• using a secondary cooling leveling roll to flatten the cladding slab conveyed from the two molding cooling rolls;
• using a rolling mill pinch roll to convey a flattened cladding slab;
• using a rolling mill to roll the cladding slab conveyed from the rolling mill pinch roll to form a cladding strip;
• using an online cooling equipment to cool the cladding strip conveyed from the rolling mill;
• using a leveler to level the cooled cladding strip;
• and
• using a dividing shear to perform cut-to-length on a leveled cladding strip or using a coiler to coil a leveled cladding strip.
