The invention relates to a method for producing a
blast furnace water-cooling wall by using
lost foam casting technique. Foam plastics is utilized to make the model of the lost foam of the
blast furnace water-cooling wall, meanwhile, after a supporting pillar is welded on a simmered cooling
water pipe of the
blast furnace water-cooling wall and masking paste is brushed, the cooling
water pipe is fixedly installed in the model of the lost foam of the blast furnace water-cooling wall, is treated with joint sealing, finishing, the painting of masking
refractory coating,
drying and ram-jolt by being arranged in a molding box, and is poured with
molten metal with qualified
smelting under a negative pressure state; and after cooling, box-opening, trimming and
processing are carried out, the blast furnace water-cooling wall product produced by the
lost foam casting technique is obtained. The method can be used for the production of the blast furnace water-cooling walls with the materials of gray
cast iron, ductile
cast iron, low
carbon steel, micro-alloying low
carbon steel, pure
copper and the like, all the performances of the blast furnace water-cooling wall are better than those of the blast furnace water-cooling walls with the same material and casted by san mold, the use amount of the moulding sand can be reduced by 90 to 95 percent, the procedure is simplified, the labor productivity is improved, the
working environment of the workers is improved, the labor intensity and operation technical difficulty of the workers are reduced, and the method has good economic and
social benefits.
