Cooling wall combining steel plates and spherical graphite cast iron and manufacturing method thereof

Abstract

The invention relates to a cooling wall combining steel plates and spherical graphite cast iron and a manufacturing method thereof; the steel plates are compounded with a body of the spherical graphite cast iron which is cast with a plurality of bolts; the steel plates arranged at the bottom surface and the side are provided with screw holes corresponding to the bolts; the body of the spherical graphite cast iron is coated with a layer of heat conduction material, and is compounded and firmly fixed with the steel plates by the plurality of bolts and nuts, so that the body of the spherical graphite cast iron is connected with the steel plates into a whole; and a compound body of the spherical graphite cast iron and the steel plates is internally cast with a plurality of cooling pipes. The manufacturing method comprises the following steps: the body of the spherical graphite cast iron is cast with the plurality of bolts, the steel plates arranged at the bottom surface and the side are processed by drilling according to the positions of the bolts on the body of the cast iron, and then the body of the cast iron is coated with the heat conduction material layer, covered by the steel plates and firmly fixed with the nuts so as to be connected with the steel plates into a whole. The invention has the advantages that the cooling wall is thin, so that the cooling effect is good; the cooling wall can adapt to the requirements of irregular shapes; and the service cycle of the product can be prolonged.

Description

technical field [0001] The invention relates to the field of metallurgical casting, in particular to a stave combined with steel plate and ductile iron and a manufacturing method thereof. Background technique [0002] The combination of steel plate and ductile iron is technically difficult. If the method of direct casting is adopted, the stave body connecting the steel plate and ductile iron will have the following situation: [0003] If the pouring temperature is high, the large flat steel plate at the bottom is easily deformed, and the cooling pipe of the inner casting may also melt through; if the pouring temperature is low, a cold gap will occur, or even insufficient pouring. [0004] The above two situations will cause the product to be scrapped. Therefore, it is necessary to design a stave that combines steel plate and ductile iron well. Contents of the invention [0005] The task of the present invention is to provide a stave combined with steel plate and ductile ...
