Regenerated cast refractory brick
The invention belongs to the technical field of refractory bricks, and particularly relates to a regenerated cast refractory brick, which comprises a body. A set of arc heat collecting holes are formed in the side, close to a fire facing face, of the body, and the heating uniformity of the body is improved through the heat collecting holes. Openings in the upper ends and the lower ends of the heatcollecting holes face the fire facing face, and the heat collecting holes are arranged in a vertical defense line and thus dust accumulated in the heat collecting holes is reduced. The circulating speed of hot air in the body is increased through the heat collecting holes; the temperature of the body is uniformly changed; the anti-cracking capability of the body is improved; the replacement frequency of the refractory bricks is further reduced; openings in the upper ends and the lower ends of the heat collecting holes face the fire facing surface; the heat collecting holes are formed in the vertical defense line, when dust carried in airflow falls into the heat collecting holes, the sliding speed of the dust along the inner walls of the heat collecting holes is increased, degradation of the heat transfer performance due to excessive dust accumulated in the heat collecting holes is prevented, uniform temperature rise of the refractory bricks is further guaranteed, and the production efficiency of a kiln is improved.
本发明属于耐火砖技术领域，具体的说是一种再生熔铸耐火砖，包括本体；本体靠近迎火面的一侧开设有一组弧形的集热孔，通过集热孔增加本体的受热均匀度；集热孔上下两端开口均朝向迎火面方向，集热孔呈竖直防线布置，用于减少集热孔堆积灰尘；本发明通过集热孔增加热气在本体内的循环速度，进而使得本体温度均匀变化，增加本体的抗裂能力，进一步减少耐火砖的更换频率，同时由于集热孔上下两端开口均朝向迎火面方向，集热孔呈竖直防线布置，使得气流中携带的灰尘掉落到集热孔时，增加灰尘沿集热孔内壁的滑落速度，避免集热孔积累灰尘过多引起的传热性能下降，进一步保证耐火砖均匀升温，增加炉窑的生产效率。
