Abstract
The utility model relates to a furnace grate 2 and a support pillar 1 for one hot air furnace of a blast furnace, which are applied to internal and external combustion type hot air furnaces which adopt seven-hole checker bricks 3. The furnace grate 2 does not adopt a cross beam to support, but a regular hexagon-shaped dabber is added on the furnace grate 2 to replace the cross beam to support. The holes of the furnace grate 2 and the seven-hole checker bricks 3 are distributed consistently. The dabber does not plug the holes at all. The furnace grate 2 is independently supported by the support pillar 1. The bottom of the furnace grate 2 and the head part of the support pillar 1 all form regular hexagon shapes with a same size. The support pillar 1 and the furnace grate 2 are two independent structural member units. Because the holes are not plugged at all, the heat exchanging area of the hot air furnace is increased, and heat energy is saved.
Description
The utility model belongs to the iron-smelting blast furnace hotblast stove with fire grate and fire grate supporting structure.
Existing Japanese Nippon Steel formula and Huo Gewenshi hotblast stove, the fire grate that seven used hole lattice bricks and dative brick adapt all adopts under the fire grate to add crossbeam, adds the shore supports structure under the crossbeam.This structural shape makes per 221.7 millimeters crossbeams length just block up two fire grate holes, and the plug-hole area accounts for 2.71% of whole chamber of hot-blast stove aisle spare, and promptly being equivalent to every cubic metre of furnace volume has just wasted 3～4m
2Heat interchanging area.Reduced the heat exchange efficiency of hotblast stove.
Task of the present utility model is to provide a kind of not fire grate of plug-hole and fire grate pillar fully that supports without crossbeam, to increase the heat interchanging area of hotblast stove, improves the heat exchange efficiency of hotblast stove.
Task of the present utility model realizes by following approach.Fire grate is added that stiffening web replaces crossbeam, and stiffening web is made regular hexagon and is made its not stifled fire grate hole, and the monolithic fire grate directly adopts the pillar independent support that adapts with self structure, and the fire grate bottom matches with the pillar head.Pillar has enough air inlet spaces, ensures that fire grate and lattice brick gas flow hole are unimpeded.Fire grate and pillar are two independent structure member unit.
The utlity model has following advantage: fire grate and pillar can reach not stifled fully lattice brick hole, have improved the heat interchanging area of hotblast stove, have brought bigger economic benefit.With 1200m
3Blast furnace is an example, and every cubic metre of furnace volume has increased about 4m
2Heat interchanging area, wind-warm syndrome can improve about 32 ℃ thus, is equivalent to iron per ton and reduces the about 7.8kg of coke consumption, nearly 5981 tons of annual saving coke.
Below in conjunction with accompanying drawing the utility model is further narrated.
Accompanying drawing is the orthogonal view of vertical heater double-edged fine-toothed comb of the present utility model and pillar.
Among the figure: seven apertures in the human head regular hexagon lattice brick 3 places on the seven apertures in the human head fire grate 2 that communicates with its pore, and fire grate 2 has the regular hexagon stiffening web, and to increase the support strength of fire grate 2, stiffening web does not block up the hole of fire grate 2 fully.Fire grate 2 is by pillar 1 independent support, and 1 and 2 connecting portions fit like a glove.Enough air inlet spaces are left at pillar 1 middle part, ensure that the gas flow hole of fire grate 2 and lattice brick 3 is unimpeded.Fire grate 2 and pillar 1 are two independent structure member unit.Be applicable to the inside and outside burning type hot-air furnace that adopts seven hole lattice bricks.
Claims (2)
1, a kind of iron-smelting blast furnace hot blast stove system of being made up of pillar 1, fire grate 2 and seven hole lattice bricks 3 is characterized in that:
A, fire grate 2 have the not stiffening web of plug-hole;
B, above-mentioned fire grate 2 directly adopt the pillar consistent with its bottom shape 1 independent support.
2, by the described iron-smelting blast furnace hot blast stove system of claim 1, it is characterized in that fire grate 2 and pillar 1 are two independent structures part unit.
