Abstract

Vynález patři k opravářaké technice vyzdiváni metalurgických agregátů a může být využit v metalurgickém a strojírenském průmyslu. Cil vynálezu - zvýšit efektivnost torkretováni vyzdívky agregátů s omezenými rozměry pracovního prostoru. K docílení tohoto cíle v trubici pro plamenové torkretováni vyzdívky metalurgických agregátů jsou tangenciální kanálky provedeny v hubicích pro přívod ohnivzdorného materiálu a paliva po tečné k jejich vnitřní ploše.The invention belongs to the repair technique of lining metallurgical aggregates and can be used in the metallurgical and mechanical engineering industries. The aim of the invention is to increase the efficiency of shotcrete lining of aggregates with limited dimensions of the working space. To achieve this aim, in the tube for flame shotcrete lining of metallurgical aggregates, tangential channels are made in the nozzles for supplying refractory material and fuel tangentially to their inner surface.
