СПОСОБ РАЗЛИВКИ КРЕМНИЯ В ИЗЛОЖНИЦУ

Изобретение относится к металлургии, в частности к электротермическому производству кристаллического кремния и может быть использовано при разливке кремния в изложницы. Цель изобретения - увеличение срока службы футеровки изложницы и уменьшение трудозатрат на удаление слитка кремния из изложницы. Для этого на поверхность подины периодически перед размещением на ней слоя из мелочи кремния наносят кислородсодержащее соединение бора при температуре поверхности подины, превышающей температуру плавления данного соединения (например борного ангидрида, борной кислоты или буры) не менее чем на 50 - 250oС, по О, 5 - 5 кг на м2 площади подины. При этом целостность футеровки сохраняется на более длительный срок за счет предотвращения приварки слитка к подине и окисления поверхности подины при высоких температурах. Срок службы футеровки изложницы увеличивается в 1,95 раза, что ведет к сокращению расхода дорогостоящих и дефицитных угольных материалов. Трудозатраты на удаление слитка из изложницы сокращаются ...

The solidified metal is then broken into pieces, e.g. by dropping a weight on to it or by driving a vehicle over it, and remelted. The slope may form part of a lagoon dug in the ground and may have a dry slag foundation 12. Ladles 1 containing the molten metal are pivotally supported on carriages 3 running on rails 4 and are tilted by a crane 7 to discharge the metal into launders 9 which discharge it over base plate 16 into the lagoon. After the metal has solidified a further layer may be poured over it.
