    摘要: The application by spraying on a ceramic furnace wall of a refractory spray material prepared by mixing a spray powder consisting of 100 pts. wt. a refractory aggregate of a predetermined particle size and 0.1-3 pts. wt. a curing accelerator with 0.5-5 pts. wt. a damping agent added thereto is accomplished with notably high levels of adhesiveness and uniformity without deteriorating the working environment with dust by a method which comprises performing said application while admixing the refractory spray material with a sodium silicate solution as a binder having a viscosity in the range of 3-10 cPs at 15 °C and containing 2-8 wt.% Na 2 0 and 8-20 wt.% Si0 2 .

    摘要: On dispose autour de la lance à oxygène des gicleurs (6) de pulvérisation qui sont protégés par des boítiers (25) isolés et alimentés en permanence par de l'air de refroidissement.
    Les gicleurs sont également alimentés en permanence par de l'air comprimé destiné à empêcher que les gicleurs ne se bouchent pas de l'extérieur vers l'intérieur.
