Water Stemming

Water stemming is plastic and generally consists of bauxite or clay clinker, soft clay, coke, silicon carbide, and high-temperature asphalt as the main raw materials, and is composed of additives that adjust the construction performance and sintering performance, and made with cement and other binders. It is mainly used for medium and small blast furnaces.

Product description

Water stemming is a specialized refractory sealing material widely used in blast furnaces and metallurgical operations to control taphole performance. It is typically composed of clay, refractory aggregates, and moisture, which give it excellent plasticity and sealing ability. When applied into the taphole, water stemming provides a reliable temporary closure, preventing uncontrolled molten iron or slag leakage while allowing safe and efficient reopening during tapping. Its plastic and cohesive nature ensures tight filling of the opening, enhancing operational safety and reducing material loss. In addition, water stemming contributes to stable furnace operation, improved tapping control, and reduced maintenance requirements. Easy to handle and apply, it is often used together with taphole clays or other plugging compounds to achieve optimal results. Water stemming is a cost-effective and practical solution in ironmaking processes, ensuring secure taphole sealing, extending furnace service life, and supporting consistent and efficient production.
