Abstract
The present invention relates to a continuous casting process for producing a composite metal slab and a square billet. Ordinary molten steel with the temperature of 1550 DEG C is added into a tundish of the ordinary molten steel of a conticaster, and is conveyed into an ordinary molten steel crystallizer by an immersed type tap hole after filtered by a filter brick of the tap hole. An ordinary slab or a square steel billet is obtained after the molten steel is cooled, and is conveyed to downwards move by the pinch rollers of the big face and the small face of the ordinary steel billet. An ordinary steel billet passes through a high-frequency intermediate heater so that the external surface of the ordinary steel billet is heated to 1250 to 1300 DEG C; then, the steel billet passes through an induction type composite molten steel tundish so that the external surface of the ordinary steel billet is heated to 1300 to 1350 DEG C, and the ordinary steel billet and the composite molten steel enter a composite steel billet crystallizer together, so that the external surface of the ordinary steel billet is compounded with a composite steel metallic layer of 10 to 20mm; composite steel and the ordinary steel billet are fused and welded into a whole to form the composite steel billet; the composite steel billet is scaled and cut off after secondary cooling under the draw of the pinch rollers of the big face and the small face to make the composite metal slab or square billet products. The present invention has the advantages and the effects of simple technology, less equipment investment, low production cost and good product quality, and is suitable for large-scale production.
