The utility model discloses a special brick supporting for the burning of a flow steel pipe brick, including a disc bracket with a through hole in the center, and a circular ring supporting surface in the middle lower concave of the disc bracket. The utility model has the advantages of simple structure, low production cost and good use effect, and can greatly increase the kiln loading rate and the finished product rate of the steel casting pipe bricks. When used, the bricks are placed on the kiln car as the bottom layer, and the mouth of the brick is placed down on the ring support surface of the brick. The brick body is effectively fixed around the brick body, and it plays a very good support and load-bearing capacity. Even if the kiln car sloshing, it will not take any questions such as the corner of the mouth and the edge off, so as to ensure the qualification of the bottom flow steel pipe brick. At the same time, the rate is more than 92%. At the same time, after the use of brick support, the erect mode of the flow steel pipe brick can be changed from two layers to three layers, which greatly increases the quantity of the kiln, effectively improves the production efficiency and reduces the production cost of the flow steel pipe brick; the pass through the center position of the brick support is beneficial to the uniform heat of the flow steel brick during the high temperature burning process. The fuel.

流钢铸管砖烧制专用砖托
本技术涉及耐火砖烧制用辅助装置,尤其是涉及一种流钢铸管砖烧制专用砖托。
技术介绍
流钢砖是砌筑在浇注铸锭用底板的沟槽内连通分钢砖和钢锭模的中空耐火砖,铸管砖属于整套流钢砖砌筑的第二套砖,砖体呈圆柱形状,一端带子口,一端带母口,如图1所示,使用时多块铸管砖子口与母口依次衔接组成钢液流道。在流钢过程中,除要求流钢铸管砖本身具有耐高温、耐冲刷、抗热震稳定性好等特性外,还要求铸管砖子口和母口之间衔接紧密,防止漏钢。由于流钢砖为圆柱型结构,烧成时如果采用平放方式,极易造成砖体的开裂和圆孔的扭曲,因此一般采用立放的方式进行烧制。立放烧制如果将母口朝下且多块砖体叠放时,由于母口壁较薄,易发生开裂,成品砖合格率极低。目前一般采用子口朝下且仅叠放两块砖进行烧制,不仅效率低,且烧制过程中窑车会发生晃动产生摩擦,子口处常出现缺角、脱边等情况,第一层砖的合格率仅在50%左右,严重影响了流钢铸管砖的产量和合格率。
技术实现思路
