Abstract
A soft water closed circulating cooling wall relates to a blast furnace cooling wall used in the steel-making field. Aiming at the problem that a blockage method used after the cooling wall is damagedcan burn out the cooling wall integrally and causes to damage the adjacent cooling walls, the utility model provides the soft water closed circulating cooling wall, wherein the structure thereof is:a metal bellows passes through the straight tube of a damaged cooling wall, two end heads of the metal bellows are respectively communicated with an upper water tube and a lower water tube through U-shaped tubes, the rear ends of the U-shaped tubes are provided with bypass mouth pieces, and the bypass mouth pieces between two adjacent U-shaped tubes are communicated through a metal hose, and the tube wall of the U-shaped tube at the joint of the metal bellows is further provided with a grouting opening. The utility model has simple structure, and convenient and quick operation, and experimentsprove that the soft water closed circulating cooling wall is capable of increasing the service life of the blast furnace by 5 years, thus, the soft water closed circulating cooling wall is in favor of popularization and application.
Description
Technical field:
The utility model relates to the blast furnace cooling stave that use in a kind of field that smelts iron.
Background technology:
It is to make the remaining bricking of cooling stave inwall form slag crust and form effective barrier to keep operating normally the type of furnace and protect furnace shell not burnt that blast furnace is established cooling stave, thereby reaches the smooth operation of furnace safety in production.Be subjected to the influence of high temperature and coal gas stream, constantly the washing away of furnace charge and mechanical movement and slag iron very easily causes slag crust to come off even cooling stave damages, and a large amount of water coolants bleed and cause furnace condition disorder in the stove, and furnace wall, hearth erosion seriously can cause hearth freeze-up and explosion hazard.
The service water open circuit cooling of blast furnace cooling stave employing, the single serpentine tube of casting in the wall, the external connection pipe full screw thread laterally divides into groups to connect.Adopt soft water closed type refrigerative blast furnace, life, 15-20 did not repair during continuous production has.Its cooling stave generally is provided with the 15-16 section, and every section piece number is generally 48 (the localized mass number is different), is cast with 4 cooling straight tubes in every, and it is one single-row to connect from bottom to top by identical numbering, outside connection Guan Quanwei welding.Behind cooling wall breakage, if by traditional stuck processing, monoblock is burnt and progressively cause adjacent cooling stave to damage in succession, thereby be difficult to reach generation stove labour life.
The utility model content:
At the problem that adopts stuck method can make the cooling stave monoblock burn and cause adjacent cooling stave to damage in succession behind the cooling wall breakage, the utility model provides a kind of cooling stave, can address the above problem preferably.
Described purpose is achieved by the following scheme:
A kind of soft water sealing and circulating cooling stave, its structure be, draws in the damaged cooling wall straight tube and wear metallic bellows, and two terminations of metallic bellows are communicated with upper and lower conduit by U type pipe respectively; Be provided with the bypass tube head in U type pipe rear end, the bypass tube head between adjacent two U type pipes is communicated with by metallic hose; With also be provided with grouting mouthful on the U type tube wall of metallic bellows junction.
The utility model is simple in structure, and is convenient to operation, adopts straight tube damaged in the cooling stave drawn and wears metallic bellows, the tight connection, recover the water flowing cooling, can make the cooling stave after the breakage continue its refrigerating function of performance, reach damaged and " regeneration " purpose, thus prolongation blast furnace work-ing life.Evidence, it can prolong blast furnace work-ing life more than 5 years, therefore was beneficial to and applied.
Description of drawings:
Fig. 1 is existing cooling wall structure synoptic diagram;
Fig. 2 is the utility model structural representation;
Fig. 3 is a U type tubular construction synoptic diagram.
Wherein, cooling stave 1, U type pipe 2, bypass tube head 2-1, grouting mouthful 2-2, water pipe 3, corrugated stainless steel tubing 4, metallic hose 5.
Embodiment:
Elaborate the utility model preferred embodiment below in conjunction with accompanying drawing.
At first determine the concrete single-row of damaged cooling wall and section layer, then the upper and lower joining outside connection pipe of damaged cooling wall straight tube is cut off;
Again the U type tube socket of making respectively with the stove skin on the welding of water pipe section counterpart, with reference to Fig. 2;
Select for use intensity height, tension, withstand voltage, capable of expansion and contraction, can be crooked, be convenient to the corrugated stainless steel tubing that is connected with steel pipe, the about 1.2～1.5mm of its skin depth, external diameter is less than caliber in the wall about 30%; Wear back band armature (iron) silk with spring, draw corrugated stainless steel tubing again and make it pass the damaged cooling wall straight tube;
Sawed-off residue corrugated tube is frustrated flat corrugated tube two sections, blocks the mouth of pipe one ripple place with two half-round bar sheets, and stiffened fluorine pad closes U type pipe up and down and to emit respectively locking.
Because draw the inside diameter of bel worn less than the raw water tubes internal diameter, so in U type pipe rear end the bypass tube head is set, with reference to Fig. 2, Fig. 3, the bypass tube head between adjacent two U type pipes is communicated with to replenish the water yield that reduces by metallic hose;
Owing between corrugated tube and former pipe certain clearance is arranged,, smashes material by grouting mouth perfusion silicon carbide in U type pipe and come filling tight, to play the effect of heat conduction so the grouting mouth is set on the tube wall of U type pipe.
Present embodiment is the protection domain that the exemplary illustration of this patent is not limited it; those skilled in the art can also carry out the part to it and change; the short of spirit that exceeds this patent all is considered as the replacement that is equal to this patent, all within the protection domain of this patent.
Claims (3)
1. soft water sealing and circulating cooling stave is characterized in that: draw in the damaged cooling wall straight tube and wear metallic bellows, two terminations of metallic bellows are communicated with upper and lower conduit by U type pipe respectively.
2. soft water sealing and circulating cooling stave according to claim 1 is characterized in that described U type pipe rear end is provided with the bypass tube head, and the bypass tube head between adjacent two U type pipes is communicated with by metallic hose.
