Description
Известный способ отливки слитков в изложницы из алюминесодержащих марок сталей имеет тот недостаток, что на поверхности этих слитков образуютс морщины, складки, неметаллические включени , плены и завороты корки. Такие слитки перед ковкой подвергают дополнительной обработке - обдирке на станках на глубину до 20 мм. Применение в процессе отливки четыреххлористого углерода, петролатума, технического нафталина и других добавок, создающих безокислительную атмосферу в изложнице, также не исключает круговой обдирки слитков перед ковкой.The known method of casting ingots into molds of aluminum-containing steel grades has the disadvantage that wrinkles, wrinkles, nonmetallic inclusions, captives and torsions of the crust form on the surface of these ingots. Such ingots before forging are subjected to additional processing - peeling on machines to a depth of 20 mm. The use of carbon tetrachloride, petrolatum, technical naphthalene and other additives in the casting process, which create a non-oxidizing atmosphere in the mold, also does not exclude circular stripping of ingots before forging.
Скоростной способ разливки исключает образование заворотов корки , улучшает микроструктуру слитков и повышает механические характеристики металла, но приводит к образованию трещин на поверхности слитка.The high-speed casting method eliminates the formation of crusting, improves the microstructure of the ingots and improves the mechanical characteristics of the metal, but leads to the formation of cracks on the surface of the ingot.
Описываемый способ устран ет указанные недостатки и позвол ет получать слитки с чистой поверхностью. Достигаетс это тем, что скоростную разливку алюминесодержащих сталей производ т через стаканчик диаметром 80-100 мм в изложницы, которые предварительно смазывают насыщенным раствором поваренной соли. Поверхность слитков, отлитых таким способом, получаетс без заворотов и плен и слитки не требуют предварительной обдирки перед ковкой. Качество поковок, полученных из необдирных слитков, не уступает качеству поковок из обдирных слитков. Кроме устранени поверхностных дефектов слитков, предложенный способ улучщает микроструктуру металла и его механические свойства.The described method eliminates these drawbacks and allows to produce ingots with a clean surface. This is achieved by the fact that high-speed casting of aluminum-containing steels is made through a glass with a diameter of 80-100 mm into molds, which are pre-lubricated with a saturated solution of table salt. The surface of ingots cast in this way is obtained without twisting, and the captivity and ingots do not require preliminary stripping before forging. The quality of forgings obtained from non-single ingots is not inferior to the quality of forged-ingot forgings. In addition to eliminating the surface defects of the ingots, the proposed method improves the microstructure of the metal and its mechanical properties.
