Description
Technical field
The utility model is related to a kind of ingot moulds, and in particular to a kind of tool belongs to smelting there are two types of the ingot mould of different tapers
Refine casting technique field.
Background technology
Ingot mould is that the important metallurgy of production steel ingot attaches.When designing ingot mould, STEELMAKING PRODUCTION is considered simultaneously and is added
Two aspects of work production require.The size and shape of one side ingot mould, which must assure that, produces good steel ingot, on the other hand
The size and shape of steel ingot must assure that following process has higher productivity and lumber recovery.
Whole inside raw steel ingot mould is in frustum shape, and cross section is square, and longitudinal section is the trapezoidal of concave section.Steel ingot
Mould from top to bottom use identical taper design, taper 2.21, steel ingot depth-width ratio be 3.21, using arc ingot butt and
General shape cap mouth design.
Taper of ingot is a major parameter in ingot shape design.In order to effectively control ingot solidification along from bottom to top
Sequence carry out, give full play to molten steel in cap mouth vulcanizes contracting function, it is ensured that steel ingot central tissue is fine and close, generally produces high-quality steel
Taper of ingot should be greater than 3%.It is ten clearly demarcated to improving ingot quality, the effect for especially improving steel ingot consistency to increase taper
Aobvious, but the increase of steel ingot section suitable for reading and cap mouth section can be led to again by increasing taper of ingot, can not only be added in this way to steel ingot
Heat and rolling deformation generate harmful effect, can also further increase cap mouth ratio, increase butt ingot amount.Shadow of the taper to cap mouth ratio
The influence rung just with depth-width ratio to cap mouth ratio is opposite, and cap mouth ratio is increased with the increasing of taper.
Depth-width ratio is also an important ingot shape design parameter, it is in addition to steel ingot shrinkage cavity, central dense degree, ingredient
Outside the primary quality measures such as segregation, steel low power have an impact, also have a direct impact to the cap mouth ratio of steel ingot, cropping rate.Depth-width ratio
Excessive, steel ingot static pressure is also big, is easy to form lower part longitudinal crack;And the nonmetal inclusion of molten steel is not easy to float, and bubble is not
Easily discharge, internal shrinkage rarefaction defect is than more serious.Depth-width ratio is too small, and field trash is easier to float in molten steel, V-type degree of segregation
It is small, but the segregation development of A types is serious.Increase steel ingot depth-width ratio advantageously reduce cap mouth ratio, reduce butt ingot amount, improve steel ingot at
Material rate.
But existing ingot mould can not make the two get both, that is, reduce cropping rate and improve central dense degree simultaneously, and also
Difficult, the low problem of demoulding efficiency in the presence of demoulding.
Utility model content
The purpose of this utility model is to provide a kind of ingot mould of tool there are two types of different tapers, is asked with solving above-mentioned technology
Topic.

The utility model has the following effects that compared with existing product:1, it is not reducing steel ingot depth-width ratio and is keeping steel ingot total
While taper is constant, increase the local taper in steel ingot stage casing, it is in steel that the design, which has selected double tapered structure, action principle,
Under conditions of the total taper of ingot is constant, targetedly increases the taper of the loose sensitive strip of steel ingot, that is, increases the taper in steel ingot stage casing,
The consistency of epimere in steel ingot can be greatly improved, while reducing ingot body to the taper at cap mouth line position, keeps steel ingot total
Taper is constant, forms the different taper in two, position up and down.It is this to design the depth-width ratio that not only ensure that steel ingot, but also reduce steel ingot
The volume of top and cap oral area point, can greatly improve lumber recovery, while the fast demoulding of double tapered being designed with conducive to steel ingot.
2, by adding cooling chamber, and design Split type steel ingot mould can further speed up the demoulding effect of steel ingot in demoulding
Rate.
