Abstract
The present invention provides a kind of manufacturing method of forging rolling composite ingot, specific steps are as follows: a) changes ingot mould ratio of height to diameter；B) ingot mould taper is changed；C) ingot mould straight section length is changed；D) ingot mould wall thickness and ingot mould structure are changed.Compared with prior art, the beneficial effects of the present invention are: by the rectangular Integral Steel ingot mould in compound quadrangle, it can be achieved that steel ingot takes into account fast forging, rolling uses, and high, the quality feature by lumber recovery.
Description
Technical field
The present invention relates to smelting equipment recovery technique field more particularly to a kind of manufacturing methods of forging rolling composite ingot.
Background technique
Fast forging, rolling are a kind of novel forging rolling techniques to grow up instantly, for steel ingot cogging molding and open die forging
The pressure processing of part is particularly suitable for the pressure processing of the higher material of alloying component.The fast forging molding of steel ingot has environmental pollution
Feature small, material consumption is few, production cost is low, it is considered to be forge one of Main way of development, each industry prosperity in the world
Country is all in Devoting Major Efforts To Developing.Steel ingot roll forming is with pollution-free, dimensional accuracy is high, at low cost, high production efficiency, lumber recovery
Feature high, product quality is high has been gradually replaced traditional forging technology by the major heavy industry enterprise favor in the world.
It is desirable to develop it is a kind of i.e. it is applicable it is fast forging, also applicable rolling ingot shape, i.e., applicable a variety of materials pressure
Processing technology, while enterprise's die cost can be reduced.
Summary of the invention
To solve the above problems, passing through compound quadrangle side the invention discloses a kind of manufacturing method of forging rolling composite ingot
Shape Integral Steel ingot mould is, it can be achieved that steel ingot takes into account fast forging, rolling uses, and has the characteristics that lumber recovery is high, quality.
In order to reach the goals above, the invention provides the following technical scheme:
A kind of manufacturing method of forging rolling composite ingot, which is characterized in that specific steps are as follows: a) change ingot mould ratio of height to diameter；B) ingot is changed
Mould taper；C) ingot mould straight section length is changed；D) ingot mould wall thickness and ingot mould structure are changed.
Further, the ratio of height to diameter of ingot mould is 1.88 in the step a).
Further, the taper of ingot mould is 3.8% in the step b).
Further, ingot mould straight section height is 750mm in the step c).
Further, in the step d) ingot mould with a thickness of 156mm.
Further, the ingot mould wall surrounding sagitta 14.5mm.
Further, the ingot mould radius of corner is 98~102mm.
Further, the ingot mould radius of corner is 100mm.
Compared with prior art, the beneficial effects of the present invention are:, can by the rectangular Integral Steel ingot mould in compound quadrangle
It realizes that steel ingot takes into account fast forging, rolling uses, and has the characteristics that lumber recovery is high, quality.
Detailed description of the invention
Fig. 1 is the schematic diagram of ingot mould in a kind of manufacturing method of forging rolling composite ingot of the present invention.
Fig. 2 is the top view of Fig. 1.
Specific embodiment
With reference to the accompanying drawings and detailed description, the present invention is furture elucidated, it should be understood that following specific embodiments are only
For illustrating the present invention rather than limiting the scope of the invention.It should be noted that word " preceding " used in the following description,
" rear ", "left", "right", "up" and "down" refer to that the direction in attached drawing, word "inner" and "outside" refer respectively to direction or remote
Direction from geometric center of specific component.
As shown, a kind of manufacturing method of forging rolling composite ingot, specific steps are as follows: a) change ingot mould ratio of height to diameter；B) it changes
Ingot mould taper；C) ingot mould straight section length is changed；D) ingot mould wall thickness and ingot mould structure are changed.
In the present embodiment, the ratio of height to diameter of ingot mould is 1.88 in step a), and the taper of ingot mould is 3.8% in step b), step
C) ingot mould straight section height is 750mm in, and ingot mould is in step d) with a thickness of 156mm, ingot mould wall surrounding sagitta 14.5mm, ingot mould fillet
Radius is 100mm.
The ratio of height to diameter of ingot mould is changed to 1.88 in step a) of the present invention, changes steel ingot from slender type to pyknic.Small
Ratio of height to diameter can reduce the jumping-up link in fast forging process, improve production efficiency, while material caused by avoiding because of jumping-up is curved
Song is to cause quality, efficiency and lost revenue.Small ratio of height to diameter ensure that deflection big when fast forging, be conducive to core quality
Improve.
Ingot mould taper is 3.8% in step b), increases steel ingot top cross section.Big taper causes steel ingot upper surface all
It is long to increase, under the plain speed of same crystallization, it is possible to reduce the load in the per unit perimeter side of ingot solidification layer top, thus emitting
Mouth lower part is not likely to produce transverse crack；Under identical note speed, molten steel rises steadily taper big simultaneously, is beneficial to prevent skull patch；And
And be conducive to steel ingot consecutive solidification from bottom to top, it is ensured that the abundant feeding in steel ingot top ensure that the compactness of steel ingot, and advantageous
In inclusion floating.
Ingot mould straight section height is 750mm in step c), deploy steel ingot height, ingot can freely again.Long and straight section can pass through tune
The mounting height and riser teeming height of whole riser end heat-insulating shield realize freely deploying for Ingot Type, realize the compatible ingot of ingot mould
Weight and purposes, improve the flexibility of production, reduce ingot mould specification, the quantity of steel mill, greatly reduce die cost and pipe
Difficulty is managed, the baking and masonry of riser or mouth of a river heelpiece is eliminated, reduces the labor intensity of worker, accelerate rhythm of production.
Ingot mould realizes low overheat with a thickness of 156mm, die wall surrounding sagitta 14.5mm, radius of corner 100mm in step d)
Consecutive solidification under degree.Thick die wall, arch, Rouno Cormer Pregrinding Wheel transition, the heat in the middle and upper part corresponding region of solidification steel ingot early period ontology
Current density is larger, and the heat flow density of corresponding region slightly reduces in the middle part of solidification latter stage steel ingot ontology, close to Above The Ingot Bottom hot-fluid
Degree influence is smaller, is conducive to steel ingot consecutive solidification from bottom to top, it is ensured that the abundant feeding in steel ingot top ensure that the densification of steel ingot
Property, the defects of improving shrinkage cavity, loose, segregation, while initial stage steel ingot chill thickness is accelerated, avoid surface of steel ingot crackle
And the generation of recess, next greatly reduces the generation of ingot mould crackle, extends Service Life of Ingot Mold.
The technical means disclosed in the embodiments of the present invention is not limited only to technological means disclosed in above embodiment, further includes
Technical solution consisting of any combination of the above technical features.It should be pointed out that for those skilled in the art
For, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also considered as
Protection scope of the present invention.
