Abstract
Винахід належить до чорної металургії, зокрема до розробки складу термостійкого та міцного чавуну для прокатних валків. Чавун містить, мас. %: вуглець 2,8-3,2, кремній 1,5-2,5, марганець 0,4-0,6, хром 0,3-0,5, нікель 0,8-1,2, мідь 0,8-1,5, ванадій 0,15-0,30, ітрій 0,05-0,08, церій 0,05-0,08, гадоліній 0,06-0,18, залізо - решта. Термостійкість запропонованого чавуну вище, ніж відомого, на 15-27 %, відносне подовження на 10-18 %, а модуль пружності менший на 9-12 %.The invention relates to ferrous metallurgy, in particular to the development of a composition of heat-resistant and durable cast iron for rolling rolls. Cast iron contains, by weight. %: carbon 2.8-3.2, silicon 1.5-2.5, manganese 0.4-0.6, chromium 0.3-0.5, nickel 0.8-1.2, copper 0, 8-1.5, vanadium 0.15-0.30, yttrium 0.05-0.08, cerium 0.05-0.08, gadolinium 0.06-0.18, iron - the rest. The heat resistance of the proposed cast iron is higher than known, by 15-27%, the elongation by 10-18%, and the modulus of elasticity by 9-12%.
