  The common reasons for the steel outlet blockage are as follows: (1) There is no steel outlet blocked after the last furnace is discharged. During smelting, the molten steel and slag enter the steel outlet, which makes the outlet blocked. (2) After the slag pouring in the last furnace, the remaining steel slag in the tapping port is blocked without all chiseling, which causes the outlet of the next furnace to be blocked. (3) The new outlet is generally small and long, and the plugging is not in place. In the smelting process, the steel and slag are filled into the hole, which causes the plugging. (4) During the tapping, the slag of the lining brick and the agglomerate falling off in the molten pool enters the steel outlet, which may also cause the steel outlet to be blocked. (5) Slag ball is used to prevent slag from steel. Before the next furnace is discharged, the slag ball of the previous furnace is not poked open, which causes the outlet to be blocked. Treatmen...

1.Optimize the heat exchange process, shorten the heat replacement time, ensure the temperature inside the furnace and the hole shape of the taphole, thus ensuring the sintering effect of the taphole filler and laying a foundation for improving the life of the taphole. 2. Appropriately increase the inner diameter of the taphole sleeve brick to shorten the tapping time, greatly reducing the oxidative erosion and mechanical erosion of the high temperature molten steel on the inner wall of the taphole. 3. Reduce the tapping temperature, the large drop of the tapping temperature reduces the erosion of the high temperature molten steel and slag on the taphole brick , and effectively improves the service life of the tapping port. 4. After tapping, the slag plug is used to block the taphole, which reduces the erosion and oxidation of the furnace gas and slag on the tapping port during the smelting process.
