Blast Furnace Stove Refractories & Operations I
Oftentimes, blast furnace hearth wear becomes the bottleneck to lengthening the blast furnace campaign. The hearth’s taphole area, which is severely eroded by the molten iron and intense slag flow, can become a challenge for stable blast furnace operation. This paper presents the recent development on taphole clay technology, which has shown excellent results in increasing taphole length, creating a good protection for the hearth. Additionally, it is shown how a high-performance taphole clay can also reduce costs in the blast furnace operation.
