Abstract

The utility model relates to a smelting kiln structure and particularly relates to an iron notch structure of a blast furnace. The iron notch structure of the blast furnace comprises iron notch channel combination bricks, the iron notch channel combination bricks comprise cube bricks, cuboid bricks and radial bricks, one inclined through hole is arranged at the center of the iron notch channel combination bricks, and the through hole is formed by upper bricks with semicircular cambered surfaces and lower bricks with lower-semicircular cambered surfaces. The iron notch structure of the blast furnace is simple in structure, easy to splice and combine, favorable for implementation, rapid in construction speed, stable in quality, high in efficiency and convenient for site masonry, reduces production cost, and prolongs service life.

Description

The blast furnace taphole structure

Technical field

The utility model relates to a kind of smelting kiln furnace structure, particularly relates to a kind of blast furnace taphole structure.

Background technology

At present, blast furnace taphole mostly adopts big brick or blast furnace standard brick brick masonry, and big brick moulding difficulty is large, difficult quality control, and yield rate is low, and difficulty of construction is larger, because the through hole of iron mouth passage is circular hole, standard square is trapezoidal brick, or straight brick, the words of building by laying bricks or stones with standard square, can only build into the circular hole of passage by laying bricks or stones a square hole or slot, the inside also needs to fill with ramming mass like this, can realize circular hole, both bothered like this, delayed again construction.

Summary of the invention

The utility model provides a kind of simple in structure in order to address the above problem, and builds blast furnace taphole structure easy and that speed of application is fast by laying bricks or stones.

The technical solution of the utility model is:

A kind of blast furnace taphole structure, comprise iron mouth combination of channels brick, described iron mouth combination of channels brick comprises the square brick, rectangular parallelepiped brick and circle brick, the central position of described iron mouth combination of channels brick is provided with a through hole that tilts, and described through hole is by consisting of with the upper brick of semicircle cambered surface with the lower brick of lower half circle cambered surface.

The diameter of described through hole is 80mm ~ 500mm, and the angle of inclination is 6 ° ~ 16 °.

Useful positively effect of the present utility model is:

1. the utility model blast furnace taphole is simple in structure, and easily match-place combination is beneficial to enforcement, and speed of application is fast, and steady quality, and efficient is high, has reduced production cost, and build by laying bricks or stones at the scene of being convenient to, and improves work-ing life.

2. because after building by laying bricks or stones, the inner face of iron mouth and cupola well inner face all are cambered surfaces, the outside of iron mouth and the contact surface of cooling stave also are cambered surfaces, can well well combine the cupola well brick of iron mouth modular tile, cooling stave etc. like this, are conducive to shutoff and sealing.
