Background technique
Carrier of the blast furnace grate for hot blast stove as top accumulation of heat checker brick, it is desirable that it divulges information checkerwork cell can be with storage
The ventilation checkerwork cell of hot checker brick matches.With the continuous development for smelting iron high wind-warm syndrome longevity hot blast stove design technology, stored by reducing
The diameter of hot checker brick ventilation checkerwork cell, can increase the heating surface (area) (HS of stove fillings, it is ensured that have in the unit time enough
Heat exchange increases the heat storage volume of stove fillings, improves blast furnace air temperature, therefore reduce accumulation of heat checker brick air grating
The diameter in hole has become the effective way for realizing high-temperature and long-efficiency hot-blast stove.This just need on fire grate it is uniformly distributed it is numerous it is tiny,
Intensive ventilation checkerwork cell, the ventilation checkerwork cell on traditional fire grate is using the forming of the processing methods such as cast form or drilling, but
Using straight hole structure, reduced using pore wall thickness is directly resulted in after swedged densely covered form, integral strength reduces, it is difficult to be
A large amount of checker brick of upper part provide effective strength support.
Summary of the invention
The present invention provides a kind of special-shaped plum blossom hole fire grates and stove fillings support system, fire grate upper section to use
The three valve plum blossom holes matched with the ventilation checkerwork cell on checker brick, middle section and lower section use three valve plum blossom of undergauge circular hole or undergauge
Hole to increase the pore wall thickness in middle section and lower section, while meeting air-conditioning requirement and intensity requirement.
In order to achieve the above object, the present invention is implemented with the following technical solutions：
A kind of abnormity plum blossom hole fire grate, including the fire grate shaped through monoblock cast, the fire grate is along high to being divided into
Upper section, middle section and lower section, upper section are uniformly distributed multiple three valves plum blossom holes, and multiple undergauge circular holes or undergauge is distributed in middle section and lower section
Three valve plum blossom holes；The center of three valve plum blossom hole of undergauge circular hole or undergauge and the center of three valve plum blossom holes are arranged in a one-to-one correspondence, undergauge
Three valve plum blossom holes are consistent with the hole shape arragement direction of three valve plum blossom holes；The internal diameter of the three valve plum blossom hole of diameter or undergauge of undergauge circular hole
Less than the internal diameter of three valve plum blossom holes.
A kind of stove fillings support system, including pillar-crossbeam-fire grate and pillar-fire grate；The fire grate
It is logical on the checker brick that three valve plum blossom holes on the abnormity plum blossom hole fire grate are supported with it using special-shaped plum blossom hole fire grate
Style hole shape, size match.
Compared with prior art, the beneficial effects of the invention are as follows：
The upper section of fire grate of the present invention is evenly distributed with design form using three common valve plum blossom holes, three valves with checker brick
Quincunx ventilation checkerwork cell matches；The middle and lower sections of fire grate use the structure of variable diameter shrinkage cavity, that is, use undergauge circular hole or undergauge three
Valve plum blossom hole, so that the wall thickness by increasing fire grate middle and lower part ventilation checkerwork cell meets support under the premise of meeting ventilation rate
The intensity requirement of checker brick.
