Abstract
The present invention discloses a method for spare parts, such as a repair slag pan with molten steel for the damage repair of metallurgy steel-smelting spare parts. Openings are arranged at the periphery of a damage position, a casting cavity is circled by a module according to the shape of the position, and then, the remaining molten steel for smelting steel is used for casting. The present invention has the characteristics of simple, convenient and reliable repair, and low steel-smelting cost.
Description
The present invention relates to the restorative procedure of a kind of field of metallurgy steel-making spare part service failure, mainly be that molten steel is repaired other spare part methods such as slag pan, as to slag ladle, cast in the middle of surplus dish, middle cast tube, ingot casting chassis, converter trunnion ring, the continuous casting clad etc. and damage and repair same being suitable for.
In background technology, the aforementioned spare part of mentioning often burns out, breaks in the STEELMAKING PRODUCTION use, as crack, the lifting hanger on nullisomic, disconnected body and slag pan, the slag ladle fractures.Because of there not being feasible restorative procedure directly to scrap, use up in the on-the-spot reality as steel scrap.
The object of the invention provides a kind of damage to other spare parts such as slag pans and repairs multiplexing other spare part methods such as molten steel reparation slag pan.
The present invention seeks to realize like this: other spare part methods such as molten steel reparation slag pan are perforates around the position of other spare parts such as slag pan that damage, and surround the casting chamber with mould by this position shape, and casting with steel-making institute residual molten steel forms again.Fill damagedly like this in breakage, and in the hole of being opened, form joint pin, guaranteed breakage casting intensity.The hole of being opened before the casting can be the hole of different shape.Described reparation can be repaired crackle, nullisomic, the disconnected body of other spare parts such as slag pan.Described perforate is to adopt single oxygen cutting.
Advantage of the present invention and good effect are: 1. utilize steel-making residue molten steel to cast, and directly use cutting with the ready-made oxygen supply facility in production factory site, have repair conveniently, rehabilitation cost is low, simple.2. adopt and repaiied the perforate on every side of part matrix, make the casting back form joint pin (muscle), guaranteed reparation position bonding strength, to reach desirable repairing effect.3. employing this method is repaired damaged spare part, and is more durable than new, prolonged spare part service life, reduced steel-making cost, helps promoting enterprise to be repaired the old and utilized scraps, and improves the business economic benefit.
Below in conjunction with accompanying drawing the present invention is described in further detail:
Fig. 1 is that slag pan is repaired the first example structure sketch.
Fig. 2 is that slag pan is repaired the second example structure sketch.
Referring to Fig. 1, have damagedly 2 on slag pan one lateral wall 1, around damaged 2, open hole 3, how many through hole 3 quantity depend on the matrix damaged condition, greatly then through hole 3 quantity should be some more for breakage.Mold 4 is blocked in the outside in lateral wall 1 then, lateral wall 1 and last through hole 3 thereof are put in the casting chamber that mould 4 forms, at last with steel-making residue molten steel casting, solidify back institute's molten steel of casting and lateral wall 1 formation one, and the repair layer that the jack-post that forms by through hole 3 connects on the lateral wall 1 is one, the existing one-tenth reparation of form removal.Aforementioned through-hole 3 also can be blind hole.
Referring to Fig. 2, when being used for repairing the slag pan of disconnected body,, also have swallow-tail form through hole or blind hole 8 along slight crack 9 edges except that around it, having through hole 3 or the blind hole, add the mould casting then and repair.Strengthen bonding strength so more and dwindle casting thickness.
Aforementioned perforate is to adopt single oxygen cutting to finish.
In like manner, can to make steel used other spare part such as slag ladle, cast surplus dish, middle cast tube, ingot casting chassis converter trunnion ring etc. and damage and repair.
Fig. 2 is the slag pan vertical view.
Claims (6)
1. molten steel is repaired other spare part methods such as slag pan, it is characterized in that it being perforate around the position of other spare parts such as slag pan that damage, and surrounds the casting chamber with mould by this position shape, forms with the residual molten steel casting of steel-making institute again.
2. repair other spare part methods such as slag pan according to the described molten steel of claim 1, it is characterized in that described perforate is a through hole.
3. repair other spare part methods such as slag pan according to the described molten steel of claim 1, it is characterized in that described perforate is a blind hole.
4. repair other spare part methods such as slag pan according to the described molten steel of claim 3, it is characterized in that described blind hole also opens at the slight crack edge, and be swallowtail shape.
5. repair other spare part methods such as slag pan according to the described molten steel of claim 1, it is characterized in that fractureing hanger on the slag pan, to repair be to open a large through-hole at its place of fractureing, groove is left in the inboard, clamps the hanger punching block at tapping, forms with the residual molten steel casting of steel-making institute again.
6. repair other spare part methods such as slag pan according to the arbitrary described molten steel of claim 1 to 5, it is characterized in that described perforate is to adopt single oxygen cutting to finish.
