Description

It flows steel cast tube brick and fires special brick support

Technical field

The utility model is related to refractory brick firing auxiliary devices, and special brick is fired more particularly, to a kind of stream steel cast tube brick Support.

Background technology

Runner brick is to build the hollow refractory brick that steel splitting brick and ingot mould are connected in the groove of cast ingot casting bottom plate by laying bricks or stones, casting Pipe brick belongs to second set of brick that a whole set of runner brick is built by laying bricks or stones, brick body cylindrical form, one end band rim of the mouth, one end band mother's mouth, such as Fig. 1 institutes Show, polylith cast tube brick rim of the mouth be connected successively with female mouth when use forms molten steel flow channel.During flowing steel, except requirement stream steel cast tube Brick itself has outside the characteristics such as high temperature resistant, resistance to erosion, heat-resistant knocking stability be good, also requires to be connected between cast tube brick rim of the mouth and mother's mouth Closely, bleed-out is prevented.

Since runner brick is if that cylindrical structure easily causes the cracking and circle of brick body using flat manner when firing The distortion in hole, therefore be generally fired by the way of standing up.If standing up firing to stack female mouth down and polylith brick body When, since female mouth wall is relatively thin, easily crack, finished bricks qualification rate is extremely low.It generally uses rim of the mouth downward at present and only stacks two Block brick is fired, and not only efficiency is low, and kiln car can shake generation friction in sintering procedure, often occur at rim of the mouth unfilled corner, Situations such as off-clip, the qualification rate of first layer brick have seriously affected the yield and qualification rate of stream steel cast tube brick only 50% or so.

Invention content

The purpose of this utility model is to provide a kind of stream steel cast tube brick burnings that product qualification rate and production efficiency can be improved Special brick support processed.

To achieve the above object, the utility model can take following technical proposals：

Stream steel cast tube brick described in the utility model fires special brick support, including the disc support of through-hole is offered at center Seat, the middle concave part of the disc bracket is at arch brace face.

The depth h in the arch brace face and the rim of the mouth of stream steel cast tube brick are highly consistent；The diameter in the arch brace face D1 is more than stream steel cast tube brick rim of the mouth 1 ~ 1.5mm of outer diameter.

The thickness H in the arch brace face is 2 ~ 3 times of arch brace face depth h.

The outer diameter D of the disc bracket compared with annulus supporting surface the big 50 ~ 80mm of diameter d1, the diameter d2 of the through-hole= 30mm~50mm。

The utility model has the advantage of simple in structure, production cost is low, and using effect is good, is greatly improved stream steel cast tube The loading of kiln rate and yield rate of brick.Brick support is placed on as bottom on kiln car when using, and card is placed on brick downwards in the rim of the mouth of adobe to be fired On the arch brace face of support, the periphery of brick support forms effective fixation to brick body, to good support and load-bearing or so, i.e., brick is held up Make kiln car shaking the problems such as rim of the mouth unfilled corner, off-clip will not occur, ensure the qualification rate of bottom current steel cast tube brick reach 92% with On；Simultaneously using after brick support, stream steel cast tube brick, which founds dress mode, to become three layers by two layers, be added significantly to loading of kiln quantity, effectively Production efficiency is improved, the production cost of stream steel cast tube brick is reduced；The through-hole that brick support center opens up simultaneously is conducive to height The thermally equivalent of runner brick, has saved fuel in warm sintering procedure.

Specific implementation mode

More detailed explanation is done to the structure of the utility model and use below in conjunction with the accompanying drawings.

As shown in Figure 2,3, the stream steel cast tube brick of the utility model fires special brick support, including through-hole 1 is offered at center Disc bracket 2, the middle concave part of disc bracket 2 is at arch brace face 3.

If the rim of the mouth depth for the stream steel cast tube brick that need to be fired is 12mm, rim of the mouth outer diameter is 100mm, then the utility model brick The depth h in the arch brace face 3 of support should be 12mm（It is highly consistent with the rim of the mouth of stream steel cast tube brick）, the diameter in arch brace face 3 D1 is 101mm（It is maximum no more than 1.5mm more than stream steel cast tube brick rim of the mouth outer diameter 1mm, it otherwise can influence to consolidate brick body It is fixed）；The outer diameter of disc bracket 2 is 160mm, and it is 24mm to require the thickness H in arch brace face 3, ensures the bearing capacity of brick support It meets the requirements；And the diameter d2 of through-hole 1 requires to be 30mm, facilitates the flowing of gas during high-temperature firing, ensures stream steel cast tube Brick internal-external temperature difference is consistent, improves its yield rate.

When loading of kiln, the brick support of the utility model is placed on kiln car, three adobe rims of the mouth to be fired overlay downwards In brick support, as shown in Figure 4.

When being fired using traditional kiln-loading method, a kiln car can put 288 pieces of the cast tube runner brick of diameter 160mm, burn It it is 200 pieces at rear certified products；After brick support, a kiln car can put 388 pieces of the cast tube runner brick of diameter 160mm, be closed after firing Lattice product are 360 pieces, and brick body qualification rate improves 23.3%, output increased 80%.
