What Are Ingot Casting Bricks
Ingot Casting Bricks, also known as runner bricks or teeming bricks, are specially shaped hollow refractory components built for bottom pouring ingot casting systems. Assembled together, they form sealed flow channels that guide molten steel from the ladle into ingot moulds smoothly. Unlike common standard refractory bricks, these custom hollow ware include central spider bricks, funnel bricks, straight runner bricks and base bricks. They are widely adopted for uphill teeming, the preferred pouring method for high-grade special steel, alloy steel and tool steel ingots.
Key Performance Advantages
Our ingot casting bricks are produced from premium fire clay, high alumina and mullite raw materials. They deliver outstanding thermal shock resistance to withstand rapid temperature changes during repeated casting cycles, avoiding sudden cracking. Smooth inner runner surfaces reduce molten steel turbulence, while excellent erosion and slag resistance extend service life. Strict dimensional control guarantees tight joints between brick pieces, effectively stopping steel leakage, penetration and non-metallic inclusions that cause ingot defects. Stable high-temperature performance helps your foundry cut scrap rate and improve finished ingot quality.
Typical Industrial Applications
This refractory product serves steel plants, special alloy foundries and heavy forging workshops. It fits carbon steel, stainless steel, tool steel and military-grade alloy ingot production. While continuous casting dominates modern steel lines, bottom pouring ingot casting remains irreplaceable for high-value, low-volume steel ingots for forging, aerospace and heavy machinery parts. Many buyers from Southeast Asia, India and the Middle East keep steady demand for complete bottom pouring brick sets.
Custom Service & Quality Assurance
As a professional refractory manufacturer, we supply standard sizes and custom shapes according to your technical drawings. Different alumina grades are available to match your pouring temperature and steel grade requirements. Every batch passes lab tests on refractoriness, cold crushing strength and thermal stability before delivery. We support full-set BP pouring packages and flexible MOQ for both trial orders and bulk shipments.
