Abstract
The invention belongs to a blast furnace part, and relates to a blast furnace tuyere medium sleeve, and the existing product has poor cooling effect, short service life of the product and large thermal deformation, so that the medium and small sleeves are difficult to replace. The invention is composed of a front cap, a body, a water inlet and a water outlet and a through-flow water partition plate. The front cap is formed by pure copper extrusion casting; the body and the through-flow water partition plate are steel pieces, a copper metallurgical bonding layer is arranged on the matching surface of the body and the large sleeve, the through-flow water partition plate is composed of two axial partition plates and a plurality of layers of radial turn-back type circulating water channel partition plates, the body and the front cap are subjected to a 1.0-2.5 MPa/20-30 min hydrostatic test, and are subjected to proportional protective welding by argon and carbon dioxide after being closely matched. The mechanical strength, surface hardness and thermal conductivity of the product are all greatly improved compared with the existing product, and the water cooling effect is obviously improved. The service life of the unit is obviously prolonged, the problem of thermal deformation is solved, and the method is well received by the users.
Description
(1) technical field
The present invention relates to the parts on the blast furnace, specifically overlap in the blast furnace wind cinder notch.
(2) background technology:
Overlap in the blast furnace wind cinder notch, the ` that promptly blows, scarfing cinder are made up of large, medium and small three external members with cover, and before being enclosed within for a short time, near burner hearth, middle cover is placed in the middle, after being enclosed within greatly, are fixed on the furnace wall, because of strong corrosion and the impact from top to bottom of high temperature furnace charge become consumable accessory.Cover is generally the fine copper manufacturing, cavity, spiral recirculated water cooling in the existing wind cinder notch.The manufacturing cost height, the ante-chamber heat exchange effect is poor, and is yielding.Patent documentation discloses the technology that a kind of patent No. is 93110164.6 " flow-dividing type bimetal welding tuyere and manufacture method thereof ", change this product into the bimetallic welding by single fine copper, the type of cooling becomes the cooling of ante-chamber multiply water channel from the helical cavity water-cooled, has obtained effect preferably.But facts have proved obvious deficiency, the one, the channel structure of ante-chamber complexity brings difficulty to casting, and the dead angle is many, rough inner surface, the water route is stopped up in easily fouling, makes heat exchange effect poor.The 2nd, big chamber does not have the circulation water channel, and heat exchange effect is poor, and cavity does not have the radial support muscle, puts easy generation thermal deformation in applying to.The 3rd, big-and-middle cover mating surface forms between steel, the iron and matches, mating surface in the big cover of easy damaged.
(3) summary of the invention:
The object of the present invention is to provide a kind ofly can overcome above-mentioned shortcoming, both can improve, reduce cost, can prolong cover and manufacture method thereof in product a kind of wind cinder notch in service life again with the copper take place of steel ratio.
The present invention is achieved in that
Cover is made up of preceding cap, body, intake-outlet, several parts of through-flow water dividing plate in this wind cinder notch, and intake-outlet is arranged on the body; Preceding cap adopts the pure copper extruding casting moulding; Body and through-flow water dividing plate adopt steel to make and form, and body cooperates the conical surface that one metallurgy of copper binder course is arranged with big cover, the through-flow water dividing plate on the body by twice axially lead directly to the intake tunnel dividing plate of ante-chamber and multilayer radially Zigzag type circulation water channel dividing plate form.
Its manufacture method is:
Preceding cap is made moulding by patented technology ZL00130380.5 " fine copper wind, cinder notch cover Extrution casting technique ", body and through-flow water dividing plate after preceding cap and body are made, adopt two ends to add a cover the soldering and sealing water pressure test by the traditional handicraft manufacturing, test pressure is 1.0-2.5MPa, and holding the pressure time is 20-30min; After the body steel part is made, cooperate surfacing or surfacing of Cu metallurgical binding layer on the conical surface with big cover at body.The body of preceding afterwards cap and coherent flowing water dividing plate is with addition of the worker, obturages between each water channel guaranteeing.Before after cap joins with body is close, clean bevel for welding, and on bevel for welding the brushing welding agent, be heated to 650-720 ℃ and use 20-24V voltage, 280-380A electric current argon gas welds with the protection of carbon dioxide proportioning.
Employing the present invention have the following advantages:
(1) use the extrusion casint moulding instead because of preceding cap, overall mechanical properties, thermal conductivity are improved, and surface of internal cavity is bright and clean, and water channel is spacious along reaching, and is difficult for stopping up.
(2) unique multilayer Zigzag type circulating cooling system designs, and makes the through middle cover ante-chamber of cold water, after multilayer is turned back, has eliminated the current dead angle, has controlled the flow velocity of recirculated water effectively, has improved heat exchanger effectiveness.
(3) cap machinery Strong degree increases before the present invention, and inner chamber has multilayer water channel membrane support again, has solved the thermal deformation problem in the middle cover use.
(4) body cooperates the conical surface to add the metallurgy of copper binder course with big cover, helps to join and locate with big cover is close, has prevented that effectively the interior pernicious gas of stove from escaping, and overcome the shortcoming because of mating surface in the big cover of cooperation easy damaged of big-and-middle cover steel and iron.
In sum, the service life of adopting the present invention to improve product effectively, and good manufacturability, manufacturing cost reduces.
(4) the invention will be further described below in conjunction with accompanying drawing:
Accompanying drawing 2 is that figure is cutd open in the exhibition of the first embodiment inner chamber water channel;
Accompanying drawing 3 is second embodiment longitudinal sectional views;
Accompanying drawing 4 is that figure is cutd open in the exhibition of the second embodiment inner chamber water channel;
(5) specific embodiment:
As shown in Figure 1, 2, cover is made up of preceding cap 2, body 3, water inlet 1, delivery port 5 and through-flow water dividing plate 4 in this wind cinder notch, preceding cap adopts the pure copper extruding casting moulding, intake-outlet is arranged on the body, body adopts the boiler steel casting, and body cooperates the conical surface that one metallurgy of copper binder course 6 is arranged with big cover, through-flow water dividing plate by twice axially lead directly to the intake tunnel dividing plate of ante-chamber and 5 radially 6 layers of Zigzag type circulation water channel dividing plate form, by the ordinary steel manufacturing, and be welded on the body.
Shown in Fig. 3,4, body 3 that overlaps in this air port and through-flow water dividing plate 4 all adopt the boiler steel monoblock cast to form.
Its manufacture method is:
Preceding cap is made moulding by patented technology ZL00130380.5 " fine copper wind, cinder notch cover Extrution casting technique ", body and through-flow water dividing plate after preceding cap and body are made, adopt two ends to add a cover the soldering and sealing water pressure test by the traditional handicraft manufacturing, test pressure is 1.0-2.5MPa, holds pressure time 20-30min.After the body steel part is made, cooperate surfacing or surfacing of Cu metallurgical binding layer on the conical surface with big cover at body.The body of preceding afterwards cap and coherent flowing water dividing plate is with addition of the worker, obturages between each water channel guaranteeing.Before after cap joins with body is close, clean bevel for welding, and on bevel for welding the brushing welding agent, be heated to 650-720 ℃, use 20-24V voltage, the 280-380A electric current, the protections of argon gas and carbon dioxide proportioning are welded.
