Abstract
The invention discloses a steel water jacket at the feed position of the furnace top of an oxygen-enriched side-blown furnace. The steel water jacket comprises a bottom plate and a cover plate. The bottom plate and the cover plate form a cavity. The outer side of the bottom plate and the outer side of the cover plate are connected with a rib plate with holes. The two ends of the bottom plate are connected with vertical plates. The vertical plates are connected with a bottom steel plate through triangular rib plates. A plurality of claw hooks are arranged below the bottom plate. A top rib plate is arranged above the cover plate. Water inlet pipes and water outlet pipes are arranged on the outer side the upper portion of the cover plate. The center of the bottom plate, the center of the cover plate and the center of the top rib plate are each provided with a through hole corresponding to a charging port. A fixing device is arranged at the through holes and comprises a flange, a flange connecting pipe and flange rib plates, wherein the flange is welded to the flange connecting pipe, and the flange and the flange connecting pipe are connected with the cover plate through the flange rib plates. The steel water jacket at the feed position of the furnace top of the oxygen-enriched side-blown furnace is simple in structure and convenient to install and replace, is installed at the feed position of the furnace top, and can protect a feed port of the furnace top against damage, improve the safety performance of the furnace and prolong the service life.
Description
Technical field
The present invention relates to Copper making equipment technical field, molten steel set at more particularly, to a kind of oxygen-enriched side-blowing furnace furnace roof charging.
Background technology
In Copper making technical field, side-blown converter is a kind of common production equipment.Most side-blown converter furnace roofs and stove at present
Wall is formed using refractory material laying, and furnace roof adopts structure of refractory, and furnace high-temperature flue gas easily washes away to furnace roof and corrodes,
Ultimately result in the side-blown converter lost of life.In addition, the slag of splash is easily tied on furnace roof in stove, easy when bulk dross comes off
Peel off refractory brick, lead to refractory brick scaling loss at furnace roof charging aperture comparatively fast, to be not easy to change, and furnace roof adopts durable material to build
Build, furnace roof is very heavy, be difficult installing/dismounting.
Content of the invention
It is an object of the invention to provide molten steel set at a kind of oxygen-enriched side-blowing furnace furnace roof charging, structure is simple, installs and changes
Convenient, it is arranged at furnace roof charging, it is to avoid damage at furnace roof charging aperture, improve the security performance of stove, increase the service life.
The technical solution used in the present invention is as follows:
Molten steel set at a kind of oxygen-enriched side-blowing furnace furnace roof charging, including base plate and cover plate, base plate and cover plate form cavity, base plate
With connect gusset with holes outside cover plate, described base plate two ends connect riser, and riser passes through triangle link of boards bottom steel plate, base plate
Lower section is provided with some claw hooks, is provided with top gusset, cover plate upper outer is provided with water inlet pipe and outlet pipe, described above described cover plate
The center of base plate, cover plate and top gusset is provided with through hole corresponding with dog-house, and described through hole is provided with fixing device, described solid
Determine device and include flange, flange connecting pipe and flange gusset, flange is welded with flange connecting pipe, flange and flange connecting pipe pass through flange muscle
Plate connecting cover plate.
Described claw hook spaced set.
Lifting hole(eyelet) is offered on described top gusset.
Compared with the prior art, beneficial effects of the present invention are as follows:
Molten steel set at the oxygen-enriched side-blowing furnace furnace roof charging of the present invention, structure is simple, is arranged at furnace roof charging, by water jacket
The effect of cooling, can avoid damaging at furnace roof charging aperture, protect liner, improve the security performance of stove, increase the service life；
It is provided with fixing device in through hole, fixing device includes flange, flange connecting pipe and flange gusset, flange is welded with flange connecting pipe,
Flange and flange connecting pipe pass through flange link of boards cover plate, it is only necessary to by the flange gusset of fixing device and cover plate point during installation
Solid welding surely, because flange and flange connecting pipe are movable, when chute abrasion or when corroding, can easy removal, readily replaceable.
Brief description
Fig. 1 is the top view of the present invention；

Specific embodiment
Referring to accompanying drawing, molten steel set at a kind of oxygen-enriched side-blowing furnace furnace roof charging, including base plate 1 and cover plate 2, base plate 1 and cover plate 2
Composition cavity, base plate 1 and cover plate 2 outside connect gusset 3 with holes, and described base plate 1 two ends connect riser 4, and riser 4 passes through triangle muscle
Plate 5 connects bottom steel plate 6, is provided with some claw hooks 7 below base plate 1, described claw hook 7 spaced set, sets above described cover plate 2
There is top gusset 8, cover plate 2 upper outer is provided with water inlet pipe 9 and outlet pipe 10, in described base plate 2, cover plate 3 and top gusset 8
The heart is provided with through hole 11 corresponding with dog-house, is provided with fixing device 12 at described through hole 11, and described fixing device 12 includes flange
13rd, flange connecting pipe 14 and flange gusset 15, flange 13 is welded with flange connecting pipe 14, and flange 13 and flange connecting pipe 14 pass through flange muscle
Plate 15 connecting cover plate 2, described top gusset 8 offers lifting hole(eyelet) 16.The present invention, structure is simple, during use, by through hole
Fixing device, flange gusset is fixed with cover plate spot welding, is arranged on the effect at furnace roof charging, cooling down by water jacket, permissible
Avoid damaging at furnace roof charging aperture, protect liner, improve the security performance of stove, increase the service life, and replacing side is installed
Just.
