Basic Refractories and Magnesia Brick Product Match
Basic refractories are important in steelmaking because steel slag is usually alkaline. Buyers should check MgO-based product coverage, technical data, consistency, and steel application knowledge.
| Product Type | What Buyers Should Verify | Typical Steel Use |
| Magnesia Brick | MgO content, density, porosity, crushing strength | Converter lining, ladle permanent lining, furnace bottom |
| Magnesia Carbon Brick | MgO content, fixed carbon, thermal shock resistance | Ladle slag line, converter working lining |
| Magnesia Chrome Brick | MgO/Cr2O3 content, corrosion resistance | Severe high-temperature zones |
| Magnesia-alumina Spinel Brick | Thermal shock resistance, structural stability | Ladle and steel furnace lining |
| Castable / Ramming Mass / Mortar | Service temperature, strength, bonding, sintering behavior | Tundish, reheating furnace, repair zones, furnace bottom |
Buyers should request technical data sheets before final selection.
Steel Furnace Lining Solution Match
Steel furnace lining is not a single-material purchase. A reliable supplier should match materials to furnace zones.
| Steel Area | Lining Requirement | Suitable Materials | Rongsheng Product Match |
| Ladle slag line | Slag erosion and thermal shock resistance | Magnesia carbon brick | Magnesia Carbon Brick |
| Ladle permanent lining | Refractoriness and basic slag resistance | Magnesia brick, spinel brick | Magnesia Brick, Magnesia-alumina Spinel Brick |
| Converter lining | Wear and basic slag corrosion resistance | Magnesia carbon brick, magnesia brick | Magnesia Carbon Brick, Magnesia Brick |
| EAF bottom | Filling and sintering performance | Ramming mass, magnesia-based materials | Ramming Mass, basic refractories |
| Tundish and repair zones | Fast repair and flexible installation | Castables, mortar, gunning mix | Refractory Castable, Refractory Mortar |
Furnace Lining Solution Workflow
| Step | Supplier Support | Buyer Benefit |
| Furnace review | Check furnace type, temperature, slag condition, and wear area | Avoids wrong material selection |
| Material selection | Match bricks, castables, ramming mass, mortar, or spinel bricks by zone | Improves lining compatibility |
| Lining optimization | Recommend materials for slag line, permanent lining, furnace bottom, or repair zone | Supports stable operation |
| Manufacturing and supply | Provide shaped and unshaped refractories | Supports one-stop procurement |
| Installation and baking | Support masonry, installation, oven baking, acceptance, and delivery | Reduces construction and startup risk |
