Abstract

Empotramiento dúctil en piezas metálicas frágiles para un anillo de molienda de pulverizador colado hecho de hierro colado blanco frágil que ha aumentado la resistencia a los fallos. La superficie del material empotrado es revestida, antes de la colada, con una papilla de partículas de óxido de magnesio en un vehículo del alcohol junto con una pequeña cantidad de partículas de Bentonita y aglutinante orgánico termocurado que resiste el ataque del metal fundido y que evita una fuerte unión con el metal fundido solidificado. El empotramiento dúctil es una estructura de poco peso de metal ventajosamente expandido. El contacto íntimo entre el empotramiento y el metal colado proporciona soporte estructural, mientras que la carencia de una fuerte unión entre el empotramiento y el hierro colado permite una deformación elástica/plástica de acero dúctil que forma el empotramiento para diferenciarlo del material de hierro blanco colado a su alrededor.Ductile embedding in fragile metal parts for a cast pulverizer grinding ring made of fragile white cast iron that has increased resistance to failures. The surface of the embedded material is coated, before casting, with a porridge of magnesium oxide particles in an alcohol vehicle together with a small amount of Bentonite particles and thermo-cured organic binder that resists the attack of molten metal and prevents a strong bond with solidified molten metal. Ductile embedding is a lightweight metal structure advantageously expanded. The intimate contact between the recess and the cast metal provides structural support, while the lack of a strong bond between the recess and the cast iron allows an elastic / plastic deformation of ductile steel that forms the recess to differentiate it from the white cast iron material around it.
