Abstract
The utility model discloses a kind of blast funnace hot blast stove lace hole checker brick, including checker brick body, described checker brick body is positive hexa-prism structure, described checker brick body central has a lace hole, several annular lace hole groups are had in this lace hole surrounding, there are some lace holes between each annular lace hole group, checker brick body upper and lower surface is provided with several grooves separately and boss.The annular lace hole group of surrounding is centrosymmetric.The center of annular lace hole group has a lace hole surrounding to have several lace holes.Lace hole, lace Kong Yu center between the group of annular lace hole is arranged in a linear.This utility model thermal property optimizes, and under the conditions of equal refractory material weight consumption or equal regenerator volume, can increase substantially heating surface (area) (HS, create favorable conditions for improving air stove wind pushing temperature；Under the conditions of identical heating surface (area) (HS, checker brick weight reduces, and regenerator volume reduces, thus decreases the investment of air stove body.
Description
Technical field
This utility model relates to Ferrous Metallurgy power-saving technology technical field, refers in particular to a kind of blast funnace hot blast stove lace hole checker brick.
Background technology
Air stove is the auxiliary equipment of blast furnace ironmaking, and its effect is to provide hot blast to blast furnace.Its operation principle is to produce high-temperature flue gas by the burner combustion coal gas of air stove, heat storage in air stove is heated, followed by cold wind passes through heat storage, carry out heat exchange with heat storage and become hot blast (high temperature air), the thermal property of conventional circular hole checker brick is mainly determined by the spacing of each checkerwork cell diameter and checkerwork cell, checker brick thermal parameter mainly has heat exchange area unit volume checker brick surface area, the live area of the whole checkerwork cell of area checker brick and the ratio etc. of checker brick basal area.Heating surface (area) (HS ensures that checker brick and fluid have enough heat exchange amounts within the unit interval, and the heat storage capacity of checker brick weight guarantee abundance is under area the same terms of living, and heat exchange area is the biggest, and thermal property is the best.
Checker brick the most conventional have: seven apertures in the human head bulk checker brick, 19 hole bulk checker brick, 30 seven apertures in the human head bulk checker brick and six 11-holes bulk checker brick, its checkerwork cell shape is circular hole, under area certain condition of living, cannot improve the heating surface (area) (HS of checker brick further, it is badly in need of a kind of structure that can improve existing conventional checker brick, optimizes its thermal property.
Utility model content
The purpose of this utility model is to overcome the shortcoming and defect of prior art, it is provided that a kind of blast funnace hot blast stove lace hole checker brick that can improve blast furnace air stove wind pushing temperature and reduce air stove investment.
This utility model is achieved through the following technical solutions:
A kind of blast funnace hot blast stove lace hole checker brick, including checker brick body, described checker brick body is positive hexa-prism structure, described checker brick body central has a lace hole, several annular lace hole groups are had in this lace hole surrounding, there are some lace holes between each annular lace hole group, checker brick body upper and lower surface is provided with several grooves separately and boss.
As preferably, the number in described lace hole is 19-72.
As preferably, described groove separately and the number of boss are 3-19.
As preferably, the annular lace hole group of described surrounding is centrosymmetric.
As preferably, the described lace hole, lace Kong Yu center between the group of annular lace hole is arranged in a linear.
As preferably, the described lace hole of each annular lace hole group switching centre and the lace hole of surrounding are arranged in a linear.
As preferably, described lace hole is evenly distributed with 12 semi-circular projection.
As preferably, the center of described annular lace hole group has a lace hole surrounding to have several lace holes.
Having 7 to 91 complete grid holes in hexagon, the pass of checker brick is lace shape column.Lace shape is to have multistage radius R1 and radius R2(Fig. 3) multi-section circular arc be formed by connecting along the round first place of a certain diameter, radius R1 and radius R2 junction use radius to be the arc transition of r.Being complete checkerwork cell in the hexagon of checker brick, hexagonal each edge has half checkerwork cell, every piece of hexagonal angle of checker brick has 1 1/3rd checkerwork cell, checkerwork cell distribution (adjacent three checkerwork cells) is equilateral triangle.
The upper surface of checker brick has 3 to 15 grooves, and lower surface has 3 to 15 boss, and when polylith checker brick are built by laying bricks or stones together, the boss of upper strata checker brick is interlocked with the groove of lower floor's checker brick, it is ensured that the stability in the large of heat storage.Boss height is less than depth of groove, flow level can be made to flow through the space between boss and groove, play distribution airflow function.The lace hole inscribed circle diameter of checker brick is 10-43mm, and the adjacent checkerwork cell spacing of checker brick is 15-65mm.Hexagonal cylindrical height 80-200mm.
Compared with prior art, the beneficial effects of the utility model are: thermal property optimization, under the conditions of equal refractory material weight consumption or equal regenerator volume, can increase substantially heating surface (area) (HS 13.46%, create favorable conditions for improving air stove wind pushing temperature；Under the conditions of identical heating surface (area) (HS, checker brick weight reduces, and can reduce checker brick investment, and regenerator volume reduces, thus decreases the investment of air stove body.
