Abstract
The utility model relates to a refractory brick, in particular to a honeycomb checker brick used on a hot blast stove of a metallurgy blast furnace. The honeycomb checker brick comprises a checker brick body in a hexagonal cylinder structure, and tapered through holes, wherein the tapered through holes are parallel with the center axis direction of the checker brick body and equidistantly arranged. First round grooves capable of communicating the tapered through holes are arranged in the front face of the checker brick body and arranged in a regular hexagon mode. Protrusions corresponding to the first round grooves are arranged on the back face of the checker brick body. Second round grooves capable of communicating the tapered through holes in the center portions of the checker brick body with the peripheral tapered through holes are arranged in the center portions of the back face of the checker brick body. Increase of channel air supply pressure is not obvious, effect of high temperature and shake on checker holes is small, deformation and displacement are not easily caused, and therefore service life of the regenerative chamber checker brick is prolonged.
Description
Technical field
The utility model relates to a kind of refractory brick, is specifically related to a kind of for the honeycomb checker brick on the hot-blast stove of metallurgy high furnace.
Background technology
The general checker brick Main Function that uses at the hot-blast stove of metallurgy high furnace is heat exchange, it offers 7 holes usually, 19 holes, 37 holes, in use, make brick build formation gas passage vertical with the hole of brick, realize heat exchange, because structural problem, the deficiency of this brick is: 1 because of the goods aperture in process of production the tapering and the error that form of depanning and build by laying bricks or stones former thereby layer by layer lattice brick vertical channel error cause whole hot-blast stove through-hole rate to only have 60%～85%, make heating process, the air-supply process produces excessive resistance, increase power of fan, produce strong arteries and veins shake, 2 wind can produce eddy current on ball top and lower cold air chamber in the air-supply process, make between each passage of checker brick air quantity inhomogeneous, low and the burner flame of the mixing of 3 burners and fuel value covers the dead angle that produces to regenerator lattice brick, make high-rise checkerwork cell when distributing heat energy and hot blast, produce the amount of stored heat deviation large, heat storage capacity reduces, 4 because long-term little coal dust effect, through-hole rate is low in addition, airflow obstruction, the friction of little coal dust air-flow and aperture sticks on the hole wall and the slagging of retractory that slowly forms, the aperture slagging of retractory of thermal efficiency high-order bit is serious, with the passing of time form the duct obstructed, the aperture diminishes, lifetime of hot-air stove is shortened, 5 heating surface (area) (HSs are dwindled, hole wall is thick, the hot blast exchange temperature reduces, 6 in construction or equipment running process, is out of shape contraction when the aperture error of falling into foreign matter or brick matter product, when causing checkerwork cell to move, air-flow is obstructed at the passage running and produces the arteries and veins shake, easily cause passage to stop up, channel failure damages checker brick lifetime of hot-air stove is shortened.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art and provides a kind of not yielding, displacement, and after piling up, easily ventilate on-deformable honeycomb checker brick.
The purpose of this utility model is achieved in that a kind of honeycomb checker brick, the checker brick body that comprises the regular hexagon column structure, the conical through-hole of and equidistant placement parallel with checker brick body central axis direction, described checker brick body front is provided with the circular groove one that conical through-hole can be communicated with, one one-tenth regular hexagon of described circular groove is arranged, the described checker brick body back side is provided with the projection corresponding with circular groove one, and centre, the described checker brick body back side is provided with the circular groove two that the conical through-hole that is positioned at checker brick body centre can be communicated with its peripheral conical through-hole.
