ESTIMATING THE DEGREE OF DEHYDROGENATION OF RAIL STEEL BY THE BATCH METHOD

OCENA STOPNIA ODWODOROWANIA STALI NA SZYNY METODA PORCJOWA

A study was made of the effectiveness of dehydrogenation of open-hearth steel in a vacuum installation by the batch method. It is found that the optimal degree of dehydrogenation of molten rail steel by the batch method of degassing is attained when the steel circulation coefficient is greater than 3.0 and the pressure in the vacuum collector ranges from 0.5 to 1.0 torr. The hydrogen content in rail steel after degassing by the batch method ranges from 2.0 to 3.7 cu cm per 100 g. An electrode addition of about 1.5 kg per ton of steel increases the hydrogen content after degassing by about 0.5 cu cm per 100 g.
