Description

чают содержание фосфора в расплаве 0,080% и хрома 0,30%. The phosphorus content in the melt is 0.080% and chromium is 0.30%.
После присадки меди и раскислени ванны 3,6 т 82%-него силикомарганца и 0,7 т 65%-ного ферросилици в результате восстаиовлени хрома и фосфора из их окислов в шлаке получают следующее содержание этих элементов в металле, вес. %:After the addition of copper and deoxidation of the bath, 3.6 tons of 82% silicomanganese and 0.7 tons of 65% ferrosilicon as a result of the reduction of chromium and phosphorus from their oxides in the slag receive the following content of these elements in the metal, weight. %:
Сг0,48Cr0.48
Р0,102Р0,102
Си0,38Si0.38
В ковш было дано 0,7 т 65%-ноРО ферросилици и 1,2 т феррохрома 800. Получена сталь следующего состава, вес. % 0.7 t of 65% ferrousilicon ferrosilicon and 1.2 tons of ferrochrome 800 were given to the ladle. Steel of the following composition was obtained, weight. %
0,110.11
0,290.29
0,450.45
0,0930.093
0,0280.028
0,770.77
0,370.37
0,350.35
Таким образом, никель и фосфор полностью , а хром более, чем на 50)% извлечены из халиловокого хромоникелевого высокофосфористого чугуна.Thus, nickel and phosphorus are completely, and chromium is more than 50)% recovered from chalic nickel chromium-phosphorus pig iron.
