Description
Technical field
The present invention relates to hot-blast stove technical field more particularly to a kind of tap hole fire grate and there is the tap hole fire grate
Stove fillings support system.
Background technology
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 enough in the unit interval
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.
Invention content
The present invention provides a kind of tap hole fire grate and stove fillings support system, the aperture of fire grate epimere is used
Coordinate in the ventilation checkerwork cell on checker brick, stage casing and hypomere use macropore to increase pore wall thickness, to meet ventilation simultaneously
It is required that and intensity requirement.
In order to achieve the above object, the present invention is realized using following technical scheme：
A kind of tap hole fire grate, includes the fire grate of monoblock cast forming, fire grate along it is high to be divided into epimere, stage casing and
Hypomere；Epimere is uniformly distributed multiple apertures；Wherein arbitrary 3 adjacent apertures press equilateral triangle and arrange, and it is every 3 it is adjacent
Aperture is one group and is uniformly divided into multiple hole groups；The stage casing of each hole group and hypomere open up macropore, the bottom of 3 apertures of each Kong Zuzhong
Portion is connected to by inclined hole with the top of macropore.
The cross section of the aperture is circle, and the cross section of the macropore is circle, and the sectional area of macropore is more than or equal to 3
The sum of sectional area of aperture.
The center line of the macropore is overlapped with the arrangement center line of 3 apertures in corresponding aperture group, i.e., in the stage casing of fire grate
And hypomere, arbitrary 3 adjacent macropores also press equilateral triangle and arrange.
A kind of stove fillings support system, including pillar-crossbeam-fire grate and pillar-fire grate；The fire grate
Using tap hole fire grate.
Compared with prior art, the beneficial effects of the invention are as follows：
The diameter of fire grate epimere aperture of the present invention is smaller, full for coordinating with the ventilation checkerwork cell of top checker brick
Sufficient air-conditioning requirement；Fire grate stage casing, the diameter macropores of hypomere are larger, and pore wall thickness is big, disclosure satisfy that the strong of support checker brick
Degree requires.
