Abstract
In the manufacture of basic steel in which the lime required for the dephosphorisation is introduced into the converter in two stages, 92-96 per cent of the lime in lump form is charged into the converter and on that the molten iron to be treated is charged. The charge is then blown until the phosphorus content of the steel is about 0,15 per cent, the converter turned into a horizontal position and the phosphatic slag is skimmed or scraped off the bath as completely as possible by a wooden scraper so that not more than 3-5 per cent of the slag remains, the remainder of the lime (8-4 per cent) in powder form added and the after blow carried out until the lime is slagged.
