Claims (1)

Способ включает управление и корректировку состава чугуна в расплаве. Способ далее содержит извлечение пробы из основного расплава и дабавление некоторого количества оксида, сульфида или оксисульфида, способного окислить количество модифицирующего вещества, преимущественно в пробе и соответствующего скорости замирания (фединга) в процессе плавки в целом. Пробе дают затвердеть в пробном сосуде, оборудованном двумя термопарами: одна в центре пробного сосуда, вторая рядом со стенкой пробного сосуда. В процессе затвердевания записывают температуру и время и рассчитывают степень образования графитных зерен. Если количество модифицирующего вещества слишком мало для образования полностью зернистого графита в течение всего периода плавки, добавляют соответствующее количество модифицирующего вещества.The method includes control and adjustment of the composition of the iron in the melt. The method further comprises removing the sample from the main melt and adding a certain amount of oxide, sulfide or oxysulfide, capable of oxidizing the amount of modifying substance, mainly in the sample and the corresponding rate of fading (fading) in the smelting process as a whole. The sample is allowed to harden in a test vessel equipped with two thermocouples: one in the center of the test vessel, the second next to the wall of the test vessel. In the process of solidification, the temperature and time are recorded and the degree of formation of graphite grains is calculated. If the amount of modifying agent is too small to form completely granular graphite during the entire melting period, add the appropriate amount of modifying substance.
