The blast furnace tapping groove is a channel for the flow of high-temperature molten iron and slag, and its refractory village must have excellent performance to meet the use under high temperature conditions.
1. Strong resistance to erosion and scouring by molten iron and slag, ensuring stable operation of the iron trench
2. Good thermal shock resistance, minimal volume change during re firing, and reduced occurrence of cracks.
3. Strong antioxidant capacity, maintaining good performance in high-temperature oxidation environments.
4. Easy to construct, can be quickly baked without bursting, and is convenient for maintenance and dismantling.
5. It does not produce harmful gases during use, does not stick to slag or iron, and has a long service life.
