Abstract
The utility model discloses an enhanced heat transfer's blast furnace stave to it is not enough to solve present blast furnace stave heat transfer efficiency, in addition the later stage condense and come off easily at the slag crust of cooling wall wall body hot side, be difficult to adapt to the problem of the high combustion intensity and the high heating load blast furnace working of a furnace. It includes cooling wall wall body and cooling wall wall body hot side along longitudinal arrangement's a plurality of horizontal rib, forms the forked tail formula between the adjacent horizontal rib and inlays the brick groove, and the rib is the staggered form of arranging of alternate, the vertical orientation of horizontal direction, arranges a rib at seat at the horizontal every interval, vertically also seat at the every interval arrange a rib. The utility model discloses cooling wall wall body heat transfer area increases, can strengthen the heat transfer of the interior air current of cooling wall hot side and stove to make the slag crust rapid coagulation and be difficult for droing, effectively protect the cooling wall not corroded by high temperature air current and material, prolong the life of cooling wall.
Description
Technical field
The utility model relates to a kind of blast furnace cooling stave of enhancement of heat transfer.
Background technology
Cooling stave is one of major equipment on iron-smelting blast furnace.Its role is to by water coolant, the heat of high temperature in stove be derived, to ensure that temperature of furnace lining meets service demand.The quality of cooling stave heat transfer property directly affects its military service effect, and then affects the service life of blast furnace.Along with the application of the raising of blast furnace equipment and high wind-warm syndrome, big coal injection, high oxygen enrichment technology, smelting strength of blast furnace improves gradually, and blast furnace heat load also constantly rises.The edge brick of cooling stave wall body and cooling stave wall body hot side that existing cooling stave is generally embedded with vertical water-cooled tube by inside forms, and cooling stave wall body hot side longitudinally arranges multiple horizontal rib, forms dovetail-indent between adjacent rib, and edge brick is embedded in dovetail-indent.The cooling stave heat transfer efficiency of this structure formation is limited, and the slag crust that the later stage condenses in cooling stave wall body hot side easily comes off, and makes cooling stave lose protection, cannot adapt to the conditions of blast furnace of high smelting intensity and high heat load completely.In recent years, having there is the phenomenon of anomalous fracture in domestic many blast furnace cooling staves, causes blast furnace to be forced to shutdown maintenance, adds enterprise operation cost.
Utility model content
The purpose of this utility model is to overcome prior art defect, provides a kind of blast furnace cooling stave of enhancement of heat transfer, to extend cooling stave service life.
The technical solution of the utility model is achieved in that a kind of blast furnace cooling stave of enhancement of heat transfer, comprise multiple horizontal rib that cooling stave wall body and cooling stave wall body hot side longitudinally arrange, brick-inlaid groove is formed between adjacent level rib, it is, rib is the arrangement form that horizontal direction is alternate, vertical direction staggers, laterally arrange a rib at interval of a seat, longitudinally also arrange a rib at interval of a seat.
Preferably, brick-inlaid groove 4 is dovetail-indent.
Blast furnace opening is after 2 ~ 3 years, and cooling stave surface edge brick corrodes totally, and cooling stave mainly relies on the slag crust that rib surface is condensed to realize self-shield.Original rib structure is that horizontal continuity is arranged, therefore in a horizontal direction, the ability of covering of slag crust is identical, once slag crust generation breaking releasing, easily causes coming off of cooling stave hot side monoblock slag crust, thus makes whole cooling stave exposed in high-temperature material and air-flow.After improvement, rib structure is that horizontal direction is alternate, vertical direction is staggeredly arranged, therefore slag crust covers ability difference on same level direction, during slag crust generation breaking releasing, may be a certain rib place wherein vertical direction on come off, other position is substantially unaffected, thus monoblock cooling stave can be avoided exposed in high-temperature material and air-flow.Meanwhile, after texture improvement, cooling stave wall body heat interchanging area increases, and heat-transfer capability strengthens, and can strengthen the heat transfer of material and air-flow in cooling stave hot side and stove, even if slag crust comes off, also can regelation within the cooling stave hot side short period of time, and available protecting cooling stave.
Accompanying drawing explanation
Fig. 1 is the utility model structural front view.
Fig. 2 is the utility model structure side view.
Fig. 3 is existing cooling wall structure front view.
In figure, 1-cooling stave wall body; 2-rib; 3-brick-inlaid groove.
Embodiment
Be further described below in conjunction with accompanying drawing:
As Fig. 1, shown in Fig. 2, a kind of blast furnace cooling stave of enhancement of heat transfer, comprise multiple horizontal rib 2 that cooling stave wall body 1 and cooling stave wall body 1 hot side longitudinally arrange, brick-inlaid groove 3 is formed between adjacent level rib 2, rib 2 is that horizontal direction is alternate, the arrangement form that vertical direction staggers, laterally arranging a rib 2 at interval of a seat, longitudinally also arranging a rib 2 at interval of a seat, the brick-inlaid groove 3 formed between adjacent level rib 2 is dovetail-indent, by to smear or spraying method is fixed in brick-inlaid groove 3 bottom edge brick, difficult drop-off, edge brick covers whole cooling stave wall body 1 hot side, select the anti-corrosion SiC refractory brick of high heat conduction.
The utility model cooling stave wall body 1 heat interchanging area increases compared with the cooling stave of whole section of rib structure in Fig. 3; the heat transfer of cooling stave hot side and gas stream in the stove can be strengthened; thus make slag crust rapid coagulation and difficult drop-off; available protecting cooling stave is not corroded by high temperature gas flow and material, extends the work-ing life of cooling stave.In addition, the utility model can also save certain wall body material, reduces cooling wall manufacture cost.
Claims (2)
1. the blast furnace cooling stave of an enhancement of heat transfer, comprise multiple horizontal rib that cooling stave wall body and cooling stave wall body hot side longitudinally arrange, brick-inlaid groove is formed between adjacent level rib, it is characterized in that: rib is the arrangement form that horizontal direction is alternate, vertical direction staggers, laterally arrange a rib at interval of a seat, longitudinally also arrange a rib at interval of a seat.
