  Tapping hole fillers must have suitable sintering performance to form a sintering layer, which can prevent the leakage of high temperature molten steel to the lower part of the tapping hole and prevent accidents caused by the floating of the filler; What’s more, the thickness of the sintering layer formed by the sintering layer is required to be moderate, so that when the baffle plate at the lower part of the tapping hole is opened, the filler will fall under the action of gravity, and the sintering layer will fall under the action of gravity when the baffle at the bottom of the tap hole fillers is opened Under the action of thermal stress, the shell is broken and the gravity flow is formed. Wanhao refractory are engaged in offering? tapping hole fillers . Tap hole filler contacting with molten steel while tapping, sintered layer is formed to prevent molten steel from down-penetrating. The rest of EBT taphole filler under the sintered layer can smoothly flow out while opening...
