Abstract

The utility model provides a steel ingot mould, comprising a die body with an inner square hole, which is characterized in that the taper of the inner square hole is less than 1.2 mm and the height is from 2400mm to 2800mm. With a small taper, a high and thin rectangle inner hole, the utility model can cast slender steel billets with small taper and heavy weight. Being suitable to small sized rolling mill, the utility model may not impact on the roller and can roll in one heat so that completely meets the requirement of technology in the production of rolling mill. Thereby, the steel ingot mould is of low cost, low energy consumption and no reinvestment any more.

Description

A kind of ingot mould

Technical field

The utility model relates to a kind of ingot mould, belongs to steelmaking technical field.

Background technology

Traditional moulded steel ingot mould, no matter it is up big and down small or up-small and down-big, when upright casting became the square steel ingot, its tapering was common between 1.5～2.5, made steel ingot be short-thick type, with the filling of shrinkage cavity in the middle of guaranteeing, improved the interior solid performance.But the steel ingot of this short-thick type requires the rod footpath of milling train also to increase, to adapt to rolling requirement when sending into mill milling thereupon.This certainly will will increase big roller footpath milling train, perhaps increase cogging equipment, thereby increase investment, energy consumption and production cost, in being unfavorable for, the development of small enterprise.Therefore, be necessary prior art is improved.

Summary of the invention

The purpose of this utility model is to provide a kind of mill rolls footpath that need not to change, and need not to increase investment, keeps low energy consumption, the slender type ingot mould of low-cost production.

The utility model is realized by following technical proposal: it comprises that endoporus is square die body, it is characterized in that the tapering of square inner bore is lower than 1.2, Kong Gaowei 2400～2800mm.

Described square inner bore is up big and down small taper hole, perhaps is up-small and down-big taper hole, so that the demoulding.

The utlity model has following advantage and effect: because such scheme, it is little to make the ingot mould of the utility model have a tapering, and the elongated square inner bore that the hole is tall and big is the elongated steel billet of the little Heavy Weight of tapering with its steel ingot of casting out, it is rolling to be suitable for bar milk, and can not impact by breaker roll, one-heating forming satisfies the technological requirement that milling train is produced fully, therefore, be a kind of low cost, low energy consumption, the practical ingot mould that need not to reinvest.

The specific embodiment

Fig. 1 is the vertical structure figure of the utility model,

Fig. 2 is the cross-sectional configuration figure of the utility model.

Below in conjunction with accompanying drawing the utility model is described further.

Among the figure, 1 is the ingot mould die body, and 2 for being located at the square inner bore in the die body, and endoporus is up-small and down-big taper hole, and its tapering is 1.1, and the height in hole is 2600mm, and 3 is lifting hug.

Claims

1, a kind of ingot mould, it comprises that endoporus is square die body, it is characterized in that the tapering of square inner bore is lower than 1.2, Kong Gaowei 2400～2800mm.

2, ingot mould according to claim 1 is characterized in that described square inner bore is up big and down small taper hole, perhaps is up-small and down-big taper hole.
