Abstract

"CANAL DE SANGRIA PARA FORNOS DE FUNDIçãO E PANELAS DE FUNDIçãO". Ao se realizar a retirada de fundido de um compartimento metalúrgico de fundição por meio de uma abertura de sangria disposta no fundo do forno, pode surgir um turbilhão oco (vortex) que leva a juntar escória indesejada. Para evitar a formação do turbilhão propõe-se, pelo invento, dar ao canal de sangria (11) um formato que saia do circular e que pelo menos do lado da entrada do fundido (12) apresente forma de fenda ou elíptica."BLEEDING CHANNEL FOR FOUNDRY OVENS AND FOUNDRY PANS". When the melt is removed from a foundry metallurgical compartment by means of a bleed opening located at the bottom of the furnace, a hollow vortex (vortex) may appear that leads to the joining of unwanted slag. In order to avoid the formation of the tourbillon, it is proposed, by the invention, to give the bleed channel (11) a shape that leaves the circular and that, at least on the side of the entrance of the melt (12), presents a slit or elliptical shape.
