Description
Technical Field
[0001] This utility model relates to the field of refractory brick production technology, and in particular to a casting mechanism for steel ladle permeable bricks. Background Technology
[0002] Permeable bricks, with their single-hole structure and use of ordinary refractory materials, have uncontrollable permeability, are easily clogged by steel slag, and have a short service life. They are only suitable for smelting ordinary steel grades. In the mid-to-late 20th century, with the popularization of ladle refining technology, permeable bricks evolved towards multi-slit, straight-hole, and diffused structures, and high-performance materials such as silicon carbide and magnesium aluminum spinel were introduced to improve corrosion resistance and permeability stability. This technological progress directly reflects the advancement and greening level of smelting processes. As the steel industry transforms towards high-end and intelligent manufacturing, the research and development of permeable bricks will continue to focus on longevity, precision, and environmental protection, becoming a key link in promoting the high-quality development of the steel industry.
[0003] In the iron and steel smelting industry, permeable bricks in ladles are core components of ladle refining and post-furnace processing, and their performance directly affects the quality of molten steel. Permeable bricks allow argon gas to enter the molten steel through narrow slits, promoting circulation, accelerating the melting of alloys and fluxes, achieving uniformity in steel composition and temperature, and effectively removing non-metallic inclusions and harmful gases.
[0004] In the traditional production process of steel ladle permeable bricks, the reserved gap hole positions and the installation of silicon carbide rods, along with the open mold design, make it easy for the cast material to spill out during vibration. Furthermore, the end face of the finished permeable bricks needs to be additionally processed into an inwardly concave spherical groove, increasing costs. The fixing method makes it difficult to ensure that the plastic strip remains taut during vibration, affecting the straightness of the gap holes. The complex structure and cumbersome preliminary preparation procedures also restrict the improvement of production efficiency. Utility Model Content
