Abstract

A 5.8-ton steel ingot mold is mainly used for steel ingot casting and comprises an outer shell; an inner cavity is arranged inside the outer shell; the outer shell is a tapered quadrangular frustum with a U-shaped axial section; the taper of the larger facet of the inner cavity is 1.596/100, while the taper of the smaller facet of the inner cavity is 3.253/100; the mold is characterized in that the outer shell is 2,120 mm high; the upper end face of the outer shell is 1,036 mm long and 953 mm wide; the lower end face of the outer shell is 920 mm long and 790 mm wide; the inner cavity is 1,990 mm high; the upper end face of the inner cavity is 716 mm long and 623 mm wide; and the lower end face of the inner cavity is 662 mm long and 512 mm wide. The steel ingot cast by the utility model has lower comprehensive degradation ratio after being rolled, for instance, the comprehensive degradation ratio of the steel rolled axle is usually 1.77% to 2.00%, thereby significantly improving the quality of steel products and improving the economic benefits of enterprises.

Description

A kind of 5.8 tons of ingot moulds

Technical field

The utility model is mainly used in the cast steel ingot, is specifically related to a kind of 5.8 tons of ingot moulds.

Background technology

At present, the mould that each smelter is produced steel ingot is a 5.6t steel ingot mould, the tapering of this mould adjacent side varies in size, be that big or small face cone degree is asymmetric, the steel ingot of producing, the comprehensive degradation rate higher (for example: axle steel is generally 4.75%～6.53%) in rolling back, the higher production that is not only restricting enterprise of steel ingot rolling back degradation rate, and economic benefit of enterprises had a significant impact.

Illustrate: after " degradation " refers to that steel ingot is rolling,, be downgraded to other low-grade kind because of the specification requirement that quality does not reach former kind.

Summary of the invention:

The utility model aims to provide the comprehensive lower a kind of 5.8 tons of ingot moulds of degradation rate in the rolling back of steel ingot.

The realization the technical solution of the utility model is: comprise shell, inner chamber is set in the shell, shell is the taper truncated rectangular pyramids that axial cross section is " U " font, the tapering that inner chamber is big is 1.596/100, the tapering of inner chamber facet is 3.253/100, the height of shell is 2120 millimeters, the length of the upper surface of shell is 1036 millimeters, and wide is 953 millimeters, and the length of the lower surface of shell is 920 millimeters, wide is 790 millimeters, the height of inner chamber is 1990 millimeters, and the length of the upper surface of inner chamber is 716 millimeters, and wide is 623 millimeters, the length of the lower surface of inner chamber is 662 millimeters, and wide is 512 millimeters.

Comprehensively the degradation rate is lower to use the utility model to water the rolling back of the steel ingot that outpours, and comprehensive degradation rate was generally 1.77%～2.00% after for example axle steel rolled, and had obviously improved the product quality of steel, had improved economic benefit of enterprises simultaneously.
