Abstract

Prezenta inventie se refera la un procedeu de obtinere a unui material refractar pentru protectia lancei de insuflare substante solide utilizata în tehnologia de tratare a otelului sau fontei, prin turnarea prin vibrare a unui amestec de materii prime, urmata de tratarea termica a prefabricatelor decofrate. Lancea protejata cu acest material refractar permite realizarea unor insuflari multiple, dând posibilitatea reconditionarii si marins durabilitatea în exploatare. Lancea de insuflat substante solide, concomitent cu barbotarea de gaze inerte, poate fi folosita în tehnologia de tratament al otelului, indiferent de agregatul de obtinere a fontei în oalele de transport uzuale. Se poate extinde utilizarea si pentru operatiile de barbotare cu gaze inerte, situatie în care durabilitatea este mai mare decât în cazul insuflarii de substante solide.
