Description
Technical field
The invention belongs to metal-forming techniques fields, and in particular to a method of manufacture blast-furnace tuyere.
Background technique
Blast-furnace tuyere is the important component on Iron Works, the high-temperature hot-air and furnace bottom coke oxygen be blown by blast-furnace tuyere
Change burning and generate carbon monoxide, carbon monoxide restores originally in high temperature rising with iron existing for oxide form.Blast furnace wind
Mouth has the characteristics that good conductibility, cooling uniform, cooling efficiency height, dense structure, wearability are good.
Blast-furnace tuyere is mainly high-purity red copper material at present, different can be examined from the intensity, rigidity, crack resistance in air port
Consider, material quality status has forging, copper sheet to roll, casts different states.
The main manufacture methods in air port are castings at present, and material is fine copper (oxygen-free copper), and weight is about at several hundred kilograms to one
Ton or so；Fine copper price is high, and manufacturing cost is high.In order to reduce cost, there is producer to invent Copper steel cladding technology manufacture air port, i.e.,
Copper and steel are combined with each other by special welding method, but since two kinds of material properties are entirely different, there are one for weld strength
Determine problem, supply opening model is impacted, also paid copper-steel composite plate on probation shapes air port scheme, but air port forming technique
The mechanical performance and elongation percentage of complexity, copper and steel are widely different, and the part that this composite plate will shape such complexity is also highly difficult,
So far there has been no this composite plate forming air ports successfully to report.
Summary of the invention
The object of the present invention is to provide a kind of methods for manufacturing blast-furnace tuyere, to make up the deficiencies in the prior art.
To solve the above problems, the technical solution adopted by the present invention are as follows: a method of manufacture blast-furnace tuyere, with existing skill
Unlike art, include the following steps:
Step 1 makes blast-furnace tuyere shaping and punching mold according to blast-furnace tuyere size；
Step 2 processes stainless steel materials using press machine, is obtained stainless steel based on blast-furnace tuyere shaping and punching mold
Air port matrix, the stainless steel materials thickness are less than blast-furnace tuyere thickness；
Step 3, it is the outer surface of stainless steel air port matrix is clean and keep cleanliness；
Step 4 obtains blast-furnace tuyere using electroforming apparatus in one layer of layers of copper of outer surface electroforming of stainless steel air port matrix.
Further, the thickness of stainless steel air port matrix is not less than twice of the thickness of layers of copper.
Further, stainless steel air port matrix with a thickness of 10mm, layers of copper with a thickness of 5mm.
Further, the press machine in step 2 is four-column universal hydraulic press.
Further, for stainless steel air port matrix during electroforming, the temperature of electroforming solution is 65-80 DEG C in step 4.
The technical program selects stainless steel material to shape air port matrix, then in blast-furnace tuyere outer surface, that is, resistant to high temperature one
For the method for face electroforming in the compound one layer of copper of stainless steel surface, stainless steel ontology is corrosion-resistant, high temperature resistant, at low cost；Pass through electroforming
Method complex copper, two kinds of materials are tightly combined, and the copper dense structure that electroforming comes out, corrosion-resistant, high temperature resistant utilizes party's legal system
Wherein stainless steel accounts for bulk composition to the blast-furnace tuyere made, and greatly reduces the dosage of fine copper, has saved production cost.
Detailed description of the invention
Fig. 1 is embodiment blast-furnace tuyere cross section structure schematic diagram.
In figure, 1. layers of copper；2. stainless steel air port matrix.
Specific embodiment
Below in conjunction with embodiment, the present invention will be described in detail.Obviously, described embodiment is only this hair
Bright a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not having
Every other embodiment obtained under the premise of creative work is made, shall fall within the protection scope of the present invention.
A method of manufacture blast-furnace tuyere includes the following steps:
Step 1 makes blast-furnace tuyere shaping and punching mold according to blast-furnace tuyere size；
Step 2 processes stainless steel materials using press machine, is obtained stainless steel based on blast-furnace tuyere shaping and punching mold
Air port matrix 2, the stainless steel materials thickness are less than blast-furnace tuyere thickness；
Step 3, it is the outer surface of stainless steel air port matrix 2 is clean and keep cleanliness；
Step 4 obtains blast-furnace tuyere using electroforming apparatus in one layer of layers of copper 1 of outer surface electroforming of stainless steel air port matrix 2.
Stainless steel air port matrix 2 with a thickness of 10mm, layers of copper 1 with a thickness of 5mm.
The press machine in step 2 is four-column universal hydraulic press.
For stainless steel air port matrix 2 during electroforming, the temperature of electroforming solution is 65-80 DEG C in step 4.
