Tundish well block are compounded blocks made of high-tech ceramics as gaschannels and of high quality castables as outer body. Tundish well blocks helps inproducing highly clean liquid steel and improving the flow ability of liquid steel. Tundish well blocks for tundishes are designed to fit the specific dimensions and configuration of the tundish. They are installed in the tundish bottom or nozzle area and are typically pre-fired or pre-cured before use to ensure proper performance.
Tundish Well Block Advantages:
Tundish well blocks are typically made from high-quality refractory materials, such as magnesia carbon, alumina magnesia carbon, or alumina graphite, depending on the specific tundish design and casting requirements. These materials offer high-temperature resistance, excellent thermal shock resistance, and good resistance to erosion. Tundish well blocks are subjected to the erosive action of the molten metal and slag. They are engineered to have good erosion resistance, minimizing wear and extending the service life of the tundish lining.
Tundish Well Block Function:
Tundish well blocks may incorporate features such as dams, weirs, or refractory baffles to control the flow of steel and improve the steel quality by reducing turbulence and promoting slag separation. Our factory tundish nozzle and well block have been successfully tested in many big steel mills .Results showed that they can satisfy the production condiotions in terms of refractoriness, erosion resistance, and non-expansion. Tundish nozzle and well block good match making steelmaking more safe and no leakage. The molten steel needs to flow to the mold through a nozzle. The tundish well block holds it and makes the alignment correct. It also controls the rate of flow by facilitating the stopper’s movement.
