Water-cooling subbase

Abstract

The invention relates to a water-cooling pedestal, which comprises an upper plane, a lower plane and a molten steel injection hole, wherein the pedestal has a concave middle section. An upper cooling chamber and a lower cooling chamber are arranged inside the pedestal between the upper plane and the lower plane and are respectively composed of more than one layer of cooling pipes, and the pipe mouths on both ends of the cooling pipes are exposed for allowing cooling water to flow into or flow out of the cooling pipes. The water-cooling pedestal is arranged between a steel ingot mold and a steel ingot disc and has the following advantages and usage effects: (1) the upper cooling chamber is used to substitute for a high-temperature region that can be easily damaged by burning at the middle or the lower section of a conventional steel ingot mold to solve the failure problem of local melting loss of the steel ingot mold and reduce the cost of the steel ingot mold; (2) the lower cooling chamber is used to substitute for a high-temperature region that can be easily damaged by burning around the injection holes of the prior steel ingot disc to prevent the steel ingot disc from contacting high-temperature molten steel and to achieve a melting-loss-free work state and prolong the service life of the steel ingot disc; and (3) the problems of molten steel leakage and breakout are solved to ensure the procedure quality.

Description

technical field [0001] The invention relates to the metallurgical manufacturing industry, in particular to a water-cooled base suitable for die-casting production of steel ingots or alloy ingots. Background technique [0002] In the casting production of conventional steel ingot molds, the middle and lower high temperature areas of the steel ingot mold are easy to be burned, resulting in local melting failure of the steel ingot mold. However, the high-temperature area around the injection hole of the existing steel ingot disk is easily burned due to contact with high-temperature molten steel, thereby shortening the service life of the steel ingot disk. [0003] There is a gap between the existing steel ingot mold and the flow steel channel, and there is also a brick joint between the flow steel channel and the flow steel channel, which is prone to the problem of leakage and fire.
