Then the painting gas is muffled and the high value gas is released, which absorbs the oxygen content from the air at the entrance to the furnace, which is fed for combustion, so that an oxygen-free atmosphere is achieved in the furnace. temperature quickly develops; and a slag is formed with extremely high alkalinity and reactive capacity. According to experience, it quickly removes sulfur and phosphorus from the land, while the carbon content remains unchanged. Also the additives Ni, Cr, Wo and p. Pass without loss to the load. By gradually removing the larger part of the knot and adding lime, the last remains of phosphorus and sulfur were released. It is possible in this way, having planned a diastepi of air, to refrain from proprietary additives and other feathers! in kilns, product extremely clean as in pie. Charge analysis after melting.

ZAKLG»»F.KOZ.'ANSKICM W WAK1WIL PL PL1. Patent claim. The method of application to invertible furnaces of low-value gases, consisting of low and high-value gases, the characteristic feature is that the charge melts first with an oxidizing mixture, then the low-value gas is suppressed and the fluff gas is more strongly oppressive. as a result, in an atmosphere that is as low as possible in oxygen and at a high temperature, you throw out a slag with such high acidity and reactivity that phosphorus and sulfur from ladinil pass into the slag and are released with it without reducing the carbon content and without the transition of the additions of Cr, Ni, Wo, etc. to the slug.
