Description

Flow steel square steel brick firing brick support

Technical field

The utility model is related to refractory brick firing auxiliary devices, more particularly, to a kind of stream steel square steel brick firing 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, side Steel brick belongs to the 4th set of brick that a whole set of runner brick is built by laying bricks or stones, and brick body is the four-prism structure with centre bore, one end band rim of the mouth, One end band mother's mouth, it is specific as shown in Figure 1, polylith square steel brick rim of the mouth is connected composition molten steel flow channel successively with female mouth when using.It is flowing During steel, in addition to the characteristics such as good, also required with high temperature resistant, resistance to erosion, heat-resistant knocking stability except requiring stream steel square steel brick itself It is connected close between square steel brick rim of the mouth and female mouth, prevents bleed-out.

Since square steel brick is the four-prism structure with centre bore, if easily caused using flat manner when firing The distortion of the cracking and circular hole of brick body, therefore be generally fired by the way of standing up.If standing up firing by female mouth down And polylith brick body since female mouth wall is relatively thin, easily cracks, finished bricks qualification rate is extremely low when stacking.Rim of the mouth is generally used at present Two pieces of bricks are stacked downward and only to be fired, not only efficiency is low, and in sintering procedure kiln car can shake generation friction, rim of the mouth Often there is situations such as unfilled corner, off-clip in place, has seriously affected the yield and qualification rate of stream steel square steel brick.

Invention content

The utility model aim is to provide a kind of stream steel square steel brick firing that product qualification rate and production efficiency can be improved With brick support.

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

Stream steel square steel brick firing brick support described in the utility model, including section are square the bracket of structure, the support Through-hole is offered at the center of seat, the middle part of bracket upper surface is recessed downwards circular ring shape supporting surface, and bracket lower surface is along institute It states through-hole circumferential direction uniform intervals and is provided with multiple air channels, multiple air channels are connected with through-hole, and the width of air channel is 5 ~10mm, depth are consistent with the height h1 of circular ring shape supporting surface.

The depth h2 of the circular ring shape supporting surface is highly consistent with square steel brick rim of the mouth, and the diameter d1 of circular ring shape supporting surface is big In square steel brick rim of the mouth 1~1.5mm of outer diameter.

The height h1 of height h1=20~40mm of the circular ring shape supporting surface, circular ring shape supporting surface are circular ring shape supporting surface 2~3 times of depth h2.

Diameter d2=20mm~30mm of the through-hole.

The utility model advantage is that the rim of the mouth of square steel brick adobe to be fired is intact and blocks the circular ring shape supporting surface for being placed on bracket On, bracket has support and load-bearing effect well, effectively prevent rim of the mouth unfilled corner, off-clip etc. because caused by shaking kiln car occur The qualification rate of bottom current steel square steel brick is improved to 92% or more, substantially increases the yield rate of stream steel square steel brick by phenomenon；Simultaneously After brick support, the vertical dress number of plies of stream steel square steel brick becomes three layers by two layers, substantially increases the loading of kiln rate of stream steel square steel brick, carries High production efficiency, reduces production cost；The through-hole of brick support and the air channel being connected with through-hole can ensure high-temperature firing Steel square steel brick thermally equivalent is flowed in the process, saves fuel.

Specific implementation mode

As in Figure 2-4, stream steel square steel brick firing brick support described in the utility model, including the square structure of section Bracket 1, through-hole 2 is offered at the center of the bracket 1,2 diameter d2 of through-hole is 25mm, and the middle part of 1 upper surface of bracket is downward It is recessed circular ring shape supporting surface 3, the depth h2 of circular ring shape supporting surface 3 and highly consistent, the circular ring shape support in square steel brick rim of the mouth The diameter d1 in face 3 is more than square steel brick rim of the mouth 1~1.5mm of outer diameter；1 lower surface of bracket is along the circumferential uniform intervals setting of through-hole 2 There are four air channel 4, four air channels 4 are arranged at intervals on the center position on 1 lower surface of bracket, four side and are connected with through-hole 2 Logical, 4 depth of air channel is consistent with the height h1 of circular ring shape supporting surface 3, is further ensured that in sintering procedure the stream of air in adobe Dynamic property, keeps square steel brick internal-external temperature difference consistent, it is ensured that square steel brick thermally equivalent.

When practical loading of kiln, if square steel brick rim of the mouth height is 11mm, the depth h2 of circular ring shape supporting surface 3 is 11mm so that Square steel brick rim of the mouth, which is just blocked, to be placed on bracket 1；Square steel brick rim of the mouth outer diameter is 80mm, then the diameter d1 of circular ring shape supporting surface 3 is 81mm~81.5mm facilitates the stability that brick body is ensured while handling；The length of side of square steel brick section is 120mm, 1 section of bracket The length of side be 130mm and the thickness of circular ring shape supporting surface 3 is 30mm, it is ensured that its bearing capacity meets adobe demand.

Conventionally loading of kiln（Use two layers of adobe of vertical loading of kiln and upper and lower closed assembly）, a kiln car can put the length of side and be 512 pieces of the stream steel square steel brick of 120mm, certified products only have 380 pieces after firing；After brick support, three layers can be stacked in each brick support Steel square steel brick is flowed, a kiln car can put 768 pieces of stream steel square steel brick, and certified products are 730 pieces, and brick body qualification rate improves 20.8%, production Amount improves 92%.
