Delivery Detail: Shipped in 45 days after payment.Product detailsDuring the process of making steel in converter, a lot of steel slag in liquid state is produced. In tradition, it often uses slag stopping ball to stop slag. As the stopping ball get to the tap hole along with molten steel as well as the high steel slag viscosity, it can’t reach the tap hole most time or can’t block the tap hole effectively when the molten steel drains away. So the efficiency of the slag stopping ball is less than 70%. However, using cone stopper plug can achieve the efficiency of 96% with slag thickness less than 20mm. It greatly lower the consumption of energy, reduce the lost of the molten steel temperature and improve the safety of steel making.Features 1. Excellent thermal shock resistance. 2. Good mechanical properties and resistance to vibration. 3. Good erosion resistance. 4. Easy to use, high efficient and saving energy.SpecificationChemical compositionTP-SP01TP-SP02Component (%)Al2O3+SiO2≥45%15-20 %Fe≥ 40%60-80 %Densityg/cm 3≥ 4.5≥ 4.5Diametermm160-220160-280weightg8100-91008100-9100Refractoriness＞1750℃＞1750℃CCS1100℃≥150kg/cm31100℃≥150kg/cm31500℃≥300kg/cm31500℃≥300kg/cm3Moisture（%）≤1.0≤1.0ImagesPackaging & DeliveryNoteThe chemical composition can be adjusted as per your requirements.
