Description
7 шить его гаэонасьпценность и получить плотный по макроструктуре слиток. Соблюдение отношени скорости охлаж дени расплава к длительности Выдержки в пределах 1-3 позвол ет сохранить выоЬкотемпературную структуру расплава и обеспеч 1ть высокое качество металла. При отношении скорости охлаждени металла ко времени выдержки менее единицы не сохран етс 1высокотэмпе- ратурное состо ние рйсплава и ухудшаетс качество металла, что иллюстрируют даннь1е . При отношении скорости охлаждени мётШла ко Времени вьщержки более трех -.часть газов не успевает вьщелитьс , а металл характеризуетс повышенной газонасыщенностью. 8д Пример, Предложенный способ существл ют при выплавке сплава79F-IM 50 кг индукционшэй печи. Шихта состоит из никел марки HI Л и армко-железа. После расплавлени шихты присаживают ферромолибден марки и расплав нагревают до 170сРс, выдерживают при этой температуре 15 мин и охлаждают с различными скорост ми до 15ОО С, Отшшение скорости охлаждени расплава к длительности выдержки при1500°С измен ют в широких пределах, мен скорость охлаждени и длительность выдержки. После выдержки металл разливают в 50 кг слиток. Качество металла . оценивают по макроструктуре, содержанию газов, характеристикам пластичности и служебным свойствам. Характеристика качества металла по вариантам выплавкиприведена в таблице ,7 sew it with a gaon value and get an ingot dense in macrostructure. Compliance with the ratio of the cooling rate of the melt to the duration of the Exposure within 1-3 allows preserving the high-temperature structure of the melt and ensuring 1 high quality of the metal. When the ratio of the cooling rate of the metal to the holding time is less than unity, the first-temperature state of the alloy is not maintained and the quality of the metal deteriorates, which is illustrated by the data. With the ratio of the cooling rate of the target to the discharge time, more than three parts of the gases do not have time to make it, and the metal is characterized by high gas saturation. An example of the proposed method exists in the smelting of a 79F-IM alloy 50 kg induction furnace. The mixture consists of nickel mark HI L and Armco iron. After the charge is melted, the ferromolybdenum brand is applied and the melt is heated to 170cPc, kept at this temperature for 15 minutes and cooled at various rates to 15OOC. . After aging the metal is poured into a 50 kg ingot. The quality of the metal. evaluated by macrostructure, gas content, plasticity characteristics and service properties. Characteristics of the quality of the metal melting options given in the table,
