Abstract

La presente se refiere a una pieza cer mica refractaria, para soplado de gas, con las siguientes caracter¡sticas: por lo menos una seccion con porosidad no orientada, que se extiende desde un extremo de suministro de gas de la pieza cer mica de soplado de gas hasta una superficie frontal de salida de gas, por lo menos una seccion con porosidad orientada, en la que se halla formado por lo menos un canal de gas, que se extiende desde un extremo de suministro de gas de la pieza cer mica de soplado de gas hasta una superficie frontal de salida del gas, as¡ como por lo menos un canal de comunicacion que, considerando la tecnica de flujo de la corriente, une la seccion con porosidad orientada con la seccion con porosidad no orientada.This refers to a refractory ceramic piece, for gas blowing, with the following characteristics: at least one section with non-oriented porosity, extending from a gas supply end of the ceramic blowing piece of gas to a front gas outlet surface, at least one section with oriented porosity, in which at least one gas channel is formed, which extends from a gas supply end of the ceramic piece of gas blowing to a front surface of the gas outlet, as well as at least one communication channel which, considering the current flow technique, joins the section with porosity oriented with the section with porosity not oriented.
