Abstract
The scientific and technical manufacturing firm Etalon developed and perfected industrial technology for manufacturing SHS ferrosilicon nitride NITRO-FESIL® TL, which is a composite consisting of silicon nitride, iron silicide, and free iron. On an industrial scale together with OAO MMK and ZAO Metallurgremont test tap-hole clays are provided containing ferrosilicon nitride NITRO-FESIL® TL. Taphole clays with the new component demonstrate higher corrosion and erosion resistance, and oxidation resistance, and also better sintering capacity. As a result of this reliable sealing of iron tap-holes, a smooth, more prolonged iron and slag flow regime with stable discharge parameters is provided. The clay is recommended for introduction. Keywords: iron tap-hole, tap-hole clay, self-propagating high-temperature synthesis, ferrosilicon nitride, β-silicon nitride.
The taphole is the most vulnerable area of a blast furnace. It is periodically heated to high temperature, and then cooled rapidly to a tap-hole clay temperature applied to its [...]
