Description
(54) СПОСОБ ИЗГОТОВЛЕНИЯ ЖЕРЕБЕЕК(54) METHOD OF MANUFACTURING STALLS
Из пластин paSiViepoM 22x44 мм и столбиков диаметром 4 мм изготовл ютс жеребейки высотой 25 мм.,25 mm tall foals are made from paSiViepoM plates of 22x44 mm and 4 mm diameter columns.
Изготовленные жеребейки подвергают высокотемпературной цементации при температуре 950-970°С в среде активного стандартного карбюризатора (древесного угл , поверхность которого покрыта углекислым кальцием) в течение 40 ч до получени углерода в слое 3,5% на поверхности элементов жеребеек, глубиной до 1 мм.Made foals subjected to high-temperature cementation at a temperature of 950-970 ° C in the medium of active standard carburizer (charcoal, the surface of which is covered with calcium carbonate) for 40 hours to obtain carbon in a layer of 3.5% on the surface of the foals, to a depth of 1 mm.
Изготовленные жеребейки с обработанными поверхност ми были установлены в формы плит толщиной 25 мм и 35 мм.The made foals with treated surfaces were installed in the form of plates with a thickness of 25 mm and 35 mm.
Заливки форм производили расплавленным чугуном марки СЧ 28-48. При этом благодар це.ментации поверхности жеребеек , свариваемость их с основным металлом достигаютс при относительно низкойCasting forms produced molten iron brand MF 28-48. At the same time, due to tse.katatsii surface of the stallions, their weldability with the base metal is achieved at relatively low
температуре заливки расплавленного чугуна 1240-1250°С.the temperature of pouring molten iron 1240-1250 ° C.
Формул а изобре тени Formula ai shadow
Способ изготовлени жеребеек дл чугунного лить включающий изготовление элементов жеребейки из стального проката, скрепление элементов с последующей обработкой их поверхности, отличающийс тем, что, с целью улучщени сплавлени жеребейки с заливаемым металлом путем уменьщени температуры плавлени поверхностного сло , обработку поверхности жеребейки осуществл ют цементацией до содержани углерода 2-4%.The method of making foals for cast iron casting, which includes the manufacture of the foal elements from rolled steel, the bonding of the elements with the subsequent processing of their surface, characterized in that, in order to improve the alloying of the foal with the metal to be poured, the surface of the foal is reduced by cementation carbon 2-4%.
