长期以来,高炉炉底、炉缸砖的加工精度和运输中的破损问题,一直是筑炉工程的两个重要课题。但近几年来在技术装备方面没有更新,在加工技术上也没有更多提高。一般炉底砖仍按照单砖扭曲不超过0.25毫米,双砖不超过0.5毫米的标准。1963年修建鞍钢十号高炉时我们就是按照这个标准加工炉底粘
For a long time, the processing accuracy of blast furnace hearths and hearth bricks and the damage during transportation have been two important topics in the construction of the furnace. However, in recent years there has been no update on technical equipment and there has been no further improvement in processing technology. Generally, the bottom bricks are still in accordance with the standard of single brick twist not exceeding 0.25 mm and double bricks not exceeding 0.5 mm. When we built the No. 10 blast furnace at Anshan Iron and Steel in 1963, we processed the bottom of the furnace according to this standard.
