Abstract
Способ изготовления слитков булатной стали, характеризующийся тем, что расплав, содержащий 1-4% углерода, остальное железо, перегревают над линией ликвидус на 200-650°С и под слоем шлака выдерживают с постоянной температурой в течение 4-7 ч, затем перегретый и выдержанный расплав заливают в футерованную изложницу центрифуги с заполнением всего объема изложницы от центра до внешней ее стенки, вращают изложницу центрифуги с постоянной скоростью для обеспечения коэффициента гравитации в периферийной части изложницы от 20 до 300 при обеспечении объемного равномерного охлаждения расплава со скоростью охлаждения не более 5°С/с, а затем после охлаждения отливки в изложнице до температуры 730°С центрифугирование прекращают и далее отливку охлаждают естественным путем, при этом величину перегрева расплава вместе с футеровкой изложницы устанавливают обеспечивающей прохождение процессов кристаллизации в силовом гравитационном поле до достижения расплавом температуры начала процессов кристаллизации в обычных условиях.A method of manufacturing damask steel ingots, characterized in that the melt containing 1-4% carbon, the remaining iron, is overheated above the liquidus line by 200-650 ° C and kept under a layer of slag at a constant temperature for 4-7 hours, then overheated and the aged melt is poured into the lined centrifuge mold with filling the entire mold volume from the center to its outer wall, the centrifuge mold is rotated at a constant speed to provide a gravity coefficient in the peripheral part of the mold from 20 to 300 while ensuring uniform cooling of the melt with a cooling rate of not more than 5 ° C / s, and then after cooling the casting in the mold to a temperature of 730 ° C, centrifugation is stopped and then the casting is cooled naturally, while the value of the melt overheating together with the lining of the mold is established to ensure crystallization processes in a gravitational force field until the melt reaches the temperature of the beginning of crystallization processes under ordinary conditions.
