Description
В индукционной печи ИСТ-016 выплавл лось 150 кг стали Ст. 3. Температура металла на выпуске была 1580°С. Распыливающа головка имела сечение выходного отверсти 25 мм. Давление распыливающего воздуха 2,2 атм на форсунке. С распыливающим воздухом подавалс через специальное смешивающее устройство полистирол марки ПСБЛ-ЗМ размером до 1,0 мм в количестве 0,5; 1,0; 1,5; 2,0 кг иа плавку. Содержание кислорода в дроби было после сушки соответственно: 1,21; 0,90; 0,53 и 0,23%.In the IST-016 induction furnace, 150 kg of steel was melted. 3. The temperature of the metal on the issue was 1580 ° C. The spraying head had a 25 mm outlet opening cross section. The pressure of the atomizing air 2.2 atm at the nozzle. With spraying air, PSBL-3M polystyrene of up to 1.0 mm in size in the amount of 0.5 was supplied through a special mixing device; 1.0; 1.5; 2.0 kg of smelting. The oxygen content in the fraction was after drying, respectively: 1.21; 0.90; 0.53 and 0.23%.
Вс дробь была получена сферической формы.All fractions were spherical.
В результате опробовани данного способа установлено, что содержание кислорода в дроби, получаемой распылением, воздухом с подачей в струю его порошкообразного полистирола, резко уменьшаетс и остаетс лишь в составе окислов на поверхности гранул, образуемых в результате дальнейшей обработки.As a result of testing this method, it was found that the oxygen content in the fraction obtained by spraying air with its powdered polystyrene into the stream decreases sharply and remains only as part of oxides on the surface of the granules formed as a result of further processing.
Полученные результаты показали перспективность использовани изобретени дл получени качественной литой металлической дроби. Способ позвол ет предохран ть жидкий металл в процессе дроблени струи от насышени его кислородом. По предварительным расчетным данным ожидаемый экономический эффект составит 5-10 рублей на 1 т дроби за счет ликвидации дорогосто щего процесса восстановлени дроби, что приводит к высвобождению восстановительных печей, экономии восстановителей .(водород, азот, углерод), сокращению 1-2 человек обслуживающего персонала.The results showed the promise of using the invention to produce high-quality cast metal shot. The method allows the liquid metal to be prevented from being crushed by the jet from oxygen up. According to preliminary estimates, the expected economic effect will be 5-10 rubles per 1 ton of the fraction due to the elimination of the expensive fraction reduction process, which leads to the release of reduction furnaces, savings of reducing agents (hydrogen, nitrogen, carbon), a reduction of 1–2 staff .
