Abstract
The invention discloses a production process of a hollow tube blank. The production process is characterized by comprising the following steps of (1) smelting by an electric furnace: heating and smelting round steel by an electric furnace; (2) carrying out perforation for manufacturing a pierced billet: perforating the heated and smelted round steel by utilizing the extruding and perforating process to obtain the pierced billet; (3) carrying out electroslag remelting: performing electroslag remelting to the pierced billet; (4) carrying out defect removal: removing the defects on the inner surface and the outer surface of the pierced billet by a lathe or an elastic machine tool; and (5) producing a finished product: checking to obtain the hollow tube blank. The production process is simple, the operability is high and the finished product rate is high, and the production cost is greatly reduced, and besides, the hollow tube produced by the invention can be mainly applied to a severe environment such as an oil field so as to effectively prevent corrosion of carbon monoxide and substances with high corrosivity.
Description
Technical field
The invention belongs to hollow ingot production technology field, specifically, relate to a kind of production technology of hollow bloom.
Background technology
At present, along with the develop rapidly of modernization industry, the demand of each field to metallic article grows with each passing day, especially chemical field and the demand of energy field to metal hollow forging are doubled and redoubled, utilize hollow ingot to forge hollow forging can play a multiplier role, therefore industrial huge to hollow ingot demand.In prior art, just easily cause graphite rod cracked when the hollow ingot of casting large-scale, therefore cause consumptive material input amount large, cause manufacturing cost to raise.
Summary of the invention
The technical problem to be solved in the present invention overcomes above-mentioned defect, provides that a kind of technique is simple, low cost of manufacture and be convenient to the production technology of the hollow bloom promoted.
For solving the problem, a kind of technical scheme of the present invention is:
A production technology for hollow bloom, is characterized in that:
Step is as follows:
1), electro-smelting: utilize electric furnace to be carried out adding hot smelting by first steel; 2), perforation procedure obtains hollow forging: utilize extruding piercing process to carry out perforation procedure to adding the first steel after hot smelting, obtained hollow forging; 3), electroslag remelting: hollow forging is carried out electroslag remelting; 4), alignment and defect cleaning: alignment and deseaming are carried out to hollow pipe embryo; 5), hollow pipe is obtained by cold rolling or cold-drawn; 6), obtained finished product: after inspection, obtain hollow bloom.
In described step 1), electric furnace is middle frequency furnace, adopts funnel to feed in raw material, limit edged melting.
Described step 2) in extruding piercing process be utilize on first steel, produce hollow forging with the extruder of separate perforate device.
The equipment that in described step 3), electroslag remelting uses is single armed electroslag furnace.Or the equipment that in described step 3), electroslag remelting uses is both arms electroslag furnaces.
Surface flatness detector is used to detect hollow pipe in described step 4).
Owing to have employed above-mentioned two kinds of technical schemes, compared with prior art, technique of the present invention is simple, workable, yield rate is high, greatly reduces production cost, simultaneously, the hollow pipe that the present invention makes mainly is used in the adverse circumstances such as oil field, effectively prevent the corrosion of carbon monoxide and the stronger material of corrosivity.In addition, the hollow pipe that the present invention obtains also can be applicable to thermal power generation, nuclear power station etc., applied widely.
Detailed description of the invention

In the production technology of this enforcement, in described step 1), electric furnace is middle frequency furnace, adopts funnel to feed in raw material, limit edged melting.
Described step 2) in extruding piercing process be utilize on first steel, produce hollow forging with the extruder of separate perforate device.
The equipment that in described step 3), electroslag remelting uses is single armed electroslag furnace, or the equipment that in described step 3), electroslag remelting uses is both arms electroslag furnaces.
Surface flatness detector is used to detect hollow pipe in described step 4).
Technique of the present invention is simple, and workable, yield rate is high, greatly reduces production cost, and meanwhile, the hollow pipe that the present invention makes mainly is used in the adverse circumstances such as oil field, effectively prevent the corrosion of carbon monoxide and the stronger material of corrosivity.In addition, the hollow pipe that the present invention obtains also can be applicable to thermal power generation, nuclear power station etc., applied widely.
The present invention is not limited to above-mentioned preferred forms, and anyone should learn the structure change made under enlightenment of the present invention, and every have identical or akin technical scheme with the present invention, all belongs to protection scope of the present invention.
