The paper considers an analysis of the behavior of bismuth shot and offers technological recommendations to improve alloy process during siphon casting of steel into ingots weighing 2.8 tons. In order to increase the bismuth assimilation in steel during siphon casting, it is necessary to implement such parameters of bismuth casting and supply that bismuth evaporation and evacuation of its vapors into the atmosphere is reduced to a minimum, and the bismuth dissolution ends when a bismuth particle moves in siphon wiring channels. Linear steel casting speed in the mold up to a height of 300 - 400 mm is maintained in the range of 10 – 15 mm/s, and then the speed is reduced up to 5 – 7 mm/s and the bismuth is input. After the end of bismuth input, the linear casting speed is increased up to 10 – 15 mm/s during 2 – 5 seconds. The casting is finished with speed at a rate of 1.5 – 3 mm/s.
Keywords: free-machining steel, bismuth shot, analysis, steel, steel casting.
