Abstract
The invention provides a method for preventing high nickel steel billet from being oxidized in the heating process, which comprises the steps of wrapping the steel billet by a cold-rolled sheet, and firmly binding the steel billet by a binding tape, or covering the upper surface and the lower surface of the steel billet by the cold-rolled sheet, and fixing the cold-rolled sheet on the steel billet in a spot welding mode; after the sheet metal is fed into the furnace, the sheet metal and the strapping tape are heated normally, and the cold-rolled sheet metal and the strapping tape are melted automatically in the heating process; and (3) after the billet is discharged from the furnace, removing residues on the surface of the billet by using high-pressure water, and then normally rolling. The method can effectively avoid the direct contact of air and the surface of the steel billet, thereby delaying the continuous oxidation degree of the surface of the steel billet, reducing the thickness of an oxidation layer, reducing the burning loss rate of the high nickel steel billet in the heating process, reducing the workload of surface treatment and improving the surface quality of the high nickel steel product.
Description
Technical field
The invention belongs to the steel rolling process technical field, particularly a kind of for the method for the steel billet that reduces high Ni steel grade in the heat-processed oxidation.
Background technology
Surface oxidation is unavoidable problem in the plate of moderate thickness blank heating process, can remove the iron scale that forms in the heat-processed clean by high pressure water for common steel billet.But for the blank of special substances such as High Nickel Steel, because the iron scale densification, iron scale is connected closely with the blank matrix, relies on high pressure water can't remove the iron scale that forms in the clean heat-processed fully.The iron scale of not disposing will be pressed into surface of steel plate in the follow-up operation of rolling, form surface crater, pit, have a strong impact on the product appearance quality, can save by reconditioning, and the steel plate visual appearance is bad after increase manufacturing cost and the reconditioning.In addition, do not remove the clean iron scale frictional coefficient in can the influence of rolled process, cause occurring in the steel plate rolling process seriously upwarping or button phenomenon down, steel plate can't be finished rollingly when serious, will produce rolling waste product.
Summary of the invention
The invention provides a kind of method that prevents the oxidation of nickelic steel billet heat-processed, its purpose is intended to reduce oxidated layer thickness, reduces the burn out rate of nickelic steel billet heat-processed, reduces the work for the treatment of amount, improves the High Nickel Steel product surface quality.
For this reason, the solution taked of the present invention is:
A kind of method that prevents the oxidation of nickelic steel billet heat-processed, its concrete grammar is:
1, desire is heated steel billet and wrap up with thickness 0.6-1.2mm cold rolled sheet, and tie up firmly with strapping tape, perhaps cover the upper and lower surface of desire heating steel billet with thickness 0.6-1.2mm cold rolled sheet, and with the mode of spot welding cold rolled sheet is fixed on the steel billet.
2, the steel billet that coating is handled well is sent into process furnace and is carried out normal heating, and cold rolled sheet and strapping tape be fusing voluntarily in heat-processed.
3, after the steel billet that heats was come out by process furnace, it was clean to utilize high pressure water that the residue of billet surface is removed, and carries out normally rolling then.
Beneficial effect of the present invention is:
Owing to coated cold rolled sheet in the steel billet outside, can effectively avoid air to contact with the direct of billet surface, thereby delay the lasting degree of oxidation of billet surface, reduce oxidated layer thickness, reduce the burn out rate of nickelic steel billet heat-processed, reduce the surface treatment workload, improve the High Nickel Steel surface quality of products.Utilize this method to produce High Nickel Steel, can reduce the steel plate reconditioning quality more than 30%, improve rolling lumber recovery more than 20%.
Description of drawings
Fig. 1 ties up parcel steel billet synoptic diagram.
Among the figure: strapping tape 1, snap close 2, edge protector 3, cold rolled sheet 4, steel billet 5.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
The present invention prevents that the concrete steps of the method for nickelic steel billet heat-processed oxidation from being:
1, the cold rolled sheet 4 that desire is heated steel billet 5 usefulness thickness 1.0mm wraps up, and does not stay any slit as far as possible, reduces the possibility that contacts with air.Tie up to individual three roads in length and breadth with strapping tape 1 again, and on the edges and corners pad of the steel billet 5 that contacts with strapping tape 1 edge protector 3; Then by snap close 2 with strapping tape 1 tension, with excluding air to greatest extent with prevent from being scattered.
Another kind of method for coating is: cover the upper and lower surface that desire heats steel billet 5 with thickness 0.8mm cold rolled sheet 4, and with the mode of spot welding cold rolled sheet 4 is weldingly fixed on the steel billet 5, come off in the handling process to prevent cold rolled sheet 4.
2, the steel billet of coating being handled well 5 is sent into process furnace and is carried out normal heating, and strapping tape 1, snap close 2, edge protector 3 and cold rolled sheet 4 be fusing voluntarily in heat-processed.
3, after the steel billet 5 that heats is come out by process furnace, remove the residue on steel billet 5 surfaces clean by high pressure water; If the situation that exists strapping tape 1 not melt fully as yet, the hook of available stock is dragged it, can carry out normally rolling then.
Claims (1)
1. a method that prevents the oxidation of nickelic steel billet heat-processed is characterized in that, concrete grammar is:
