Abstract

The invention discloses a novel energy-saving pouring gate pipe cast by mixing clay, argil and bauxite. The pouring gate pipe has the advantages of light weight, favorable wear resistance, corrosion resistance, high integrated intensity and favorable integrated performance and can meet the requirements of industrial use. The pouring gate pipe greatly saves resources and energy, effectively avoidscasting defects such as adhering sand, sand inclusions, sand cuts, sand holes and the like, and enhances the cost and the quality of the casting.

Description

technical field [0001] The invention relates to the field of pipes, in particular to a pipe used for transporting liquid medium containing solid particles, powder and other substances in a kiln. Background technique [0002] Flow steel brick is a kind of hollow refractory brick that connects the sub-steel brick and the steel ingot mold in the groove of the bottom plate for ingot casting. It is commonly known as soup brick. Flow steel brick is generally a cuboid hollow clay brick with various specifications. In order to reduce the resistance during the flow of molten steel and prevent leakage of steel, it is required that the inner hole of the flowing steel brick is smooth, the shape is regular, and the joints are tight. Because it is a hollow clay brick, the flow steel brick of the prior art has defects such as sand sticking, sand inclusion, and sand washing in the casting, which makes the product have many impurities, affects product quality, and has a high defective rate. ...
