Abstract

Invenţia se referă la o metodă de tăiere a unui corp refractar, prin proiectarea, pe o suprafaţă a corpului refractar, în prezenţă de oxigen, a unui amestec de pulbere care cuprinde particule de oxidmetalic refractar şi particule combustibile, care prin combinare cu oxigenul au o ardere exotermă, formând un oxid refractar. Metoda se caracterizează prin aceea că se proiectează pe suprafaţa corpului refractar, la o temperatură cuprinsă între temperatura ambiantă şi o temperatură ridicată, un amestec de pulbere care cuprinde între 70 şi 90% în greutate particule de oxid metalic refractar, constând din oxid de magneziu şi oxid de calciu şi 10...30% în greutate particule combustibile, având o dimensiune medie sub 50 microni, alese dintre siliciu, aluminiu, magneziu şi/sau zirconiu. Raportul în greutate dintre oxidul de calciu şi oxidul de magneziu este cuprins între 5 : 1 şi 0,4 : 1.
