Anhydrous Stemming For Blast Furnace Taphole Has Good Corrosion Resistance.<br><br>Good volume stability, under high temperature have small change on the volume,no leakage of molten iron, because of volume range.<br><br>1. Block the tap hole,need the stemming with good filling ability and Sinterability.<br>2. Stable Tapping , required stemming easy open corrosion resistance, abrasion resistance<br>3. Easy to operation ,easy drilling..<br>4. Moderate plasticity, easy to operation and forming the taphole balling<br>5. Protect the cylinder,need stemming quickly heating no crack, and high adhesive strength for fresh and old stemming.
