Abstract
Inventia se refera la un procedeu si instalatie de realizare a profilelor tip fagure folosite ca umplutura a peretilor portanti pentru aeronave autocamioane, vagoane de cale ferata, nave maritime si fluviale, precum si în constructiile civile si industriale. Procedeul de realizare a profilelor tip fagure conform inventiei consta din curatirea benzii metalice, prin tragere si îndoire alternata banda fiindAmestecul pentru pulverizare cu flacara a captuselii convertizoarelor, conform inventiei, este utilizat pentru repararea fierbinte a captuselii agregatelor de topire a otelurilor si este alcatuita din 20 - 30% în greutate cocs, cu 5 -10% în greutate adaos fuzibil si 76 - 60% în greutate var, adaosul fuzibil putînd fi reprezentat, fie de zgura defurnal, cuprinzînd oxid de calciu, oxid de mangan, oxid de magneziu, oxizi de fier, de aluminiu, de siliciu si sulf, fie de un concentrat de staurolit. Amestecul se realizeaza prin maruntirea materiilor prime, cocsul, zgura de furnal sau concentratul de staurolit, varul, pîna la o fractiune cu granulatie de sub 10 mm, cu separarea substantelor straine, daca este necesar, dupa care sunt macinate pentru a fi apte pentru pulverizare în proportiile dorite.
