Abstract

Inventia se refera la un ansamblu refractar de insuflare a gazelor la masa de metal lichid si la un procedeu de realizare a ansamblului respectiv, ansamblu care este amplasat la partea inferioara a unei oale în care se afla metal lichid care urmeaza a fi barbotat cu gaze inerte cum ar fi argonul sau azotul, pentru realizarea otelurilor înalt aliate prin procedeul VAD (vacuum Argon Decarburisation) si a otelurilor cu carbon sub 0,05% prin procedeul VOD (vacuum Oxigen Decarburisation). în acest scop se urilizeaza niste blocuri permeabile din corindon, introduse într-o carcasa metalica si despartite între ele printr-un inel de azbest, blocuri care se obtin din presarea unui amestec format dintr-un material superaluminos si un liant format din argila refractara si un liant fosfatic.The invention relates to a refractory gas insufflation assembly at a liquid metal table and to a process for making the assembly, which assembly is located at the bottom of a pot containing liquid metal to be bubbled with inert gases such as argon or nitrogen, to produce high alloyed steels by the Argon Decarburisation (VAD) and carbon steels below 0,05% by the VOD (Vacuum Oxigen Decarburisation) process. For this purpose, some permeable corundum blocks are introduced, inserted into a metallic casing and separated by an asbestos ring, blocks obtained by pressing a mixture of superalloy material and a binder made of refractory clay and a phosphate binder.
