Abstract

The utility model relates to a brick for tapping hole of an open hearth furnace, which is composed of one group or a plurality of groups. Each group is divided into an upper brick and a lower brick, wherein, the upper brick is in semi-circle shape, the top of the lower brick is also in semi-circle shape, and the bottom edge is in rectangular shape. In order to guarantee the integrity of the built bricks for tapping hole, the semicircle part interface position of the upper and the lower bricks are respectively provided with grooves and convex edges which are mutually engaged. Male and female mating flanges and embedding slots are arranged among each group of the bricks. The brick is applied at the steel tapping hole of an open hearth furnace and has the advantages of convenient masonry building, long service life, etc.

Description

Brick for tapping hole of open hearth furnace

The utility model relates to a kind of open hearth tapping hole brick, belongs to the smelting iron and steel special refractories.

Before the utility model was made, steel-making belongs to magnesium brick with the open hearth tapping hole brick more or wedge type revolves brick, and the tapping hole section after building by laying bricks or stones is the garden shape more.Because the version of these bricks is unreasonable, so it is relatively poor to cause building by laying bricks or stones the back overall performance,, very easily damage under molten steel scouring and the slag etch in the high temperature thermal shock, generally be no more than service life 10 times.

It is good that the purpose of this utility model just provides a kind of overall performance, and the open hearth tapping hole brick of long service life to reduce production costs, reduces labour intensity.

Open hearth tapping hole brick of the present utility model is formed by one group or several groups, and every component is last brick and two of following bricks, and last brick wherein is semi-circular, and the top of following brick also is semicircle, and the bottom outer rim is a rectangle.At the semicircle position of upper and lower two bricks interface, leave the convex-concave bayonet socket that two bricks are meshed respectively.Also can coincide mutually for making between every group of brick, cooperate ring at the axial brick of two bricks up and down along locating to leave male and female respectively again, both play the overall performance of tapping hole brick, make things convenient for again and built by laying bricks or stones and safeguard.

The foregoing of open hearth tapping hole brick of the present utility model and brick type thereof further specify as follows in conjunction with the accompanying drawings:

Fig. 1: brick brick shape figure on the open hearth tapping hole brick,

The vertical view of Fig. 2: Fig. 1,

Fig. 3: brick brick shape figure under the open hearth tapping hole brick,

The vertical view of Fig. 4: Fig. 3.

Open hearth tapping hole brick of the present utility model is a special form brick, mainly by brick body (1), groove (2), fin (3), nib (4) and caulking groove formations such as (5).The groove of last brick (2) is meshed with the fin (3) of following brick, and upward the fin (3) of brick is meshed with the groove (2) of following brick, and in every group of brick, the nib of last group of brick (4) matches with the caulking groove (5) of the one group of brick in back.Use open hearth tapping hole brick of the present utility model, build by laying bricks or stones according to the method described above, can play the overall performance of tapping hole brick, can prolong its service life again, can reduce production costs greatly, reduce labor intensity at open hearth tapping hole place.

Claims
