摘要
Abstract
In this work,the semi-continuous induction smelting method of titanium alloy ingot was introduced.The Φ280 mm cold crucible was used to smelt TA17 alloy under different powers(450 kW,550 kW,650 kW,750 kW,800 kW).The experimental results showed that the TA17 alloy ingot could not be melted when the power was 450 kW and 550 kW,which could be melted under the power of 650 kW,750 kW and 800 kW.The TA17 alloy smelting efficiency of Φ280 mm cold crucible with different powers(650 kW,750 kW,800 kW)was calculated.According to the calculation results,the smelting process scheme was formulated and the corresponding experiments were carried out.The experimental results showed that under the condition of a certain smelting power,the alloy will not be smelted if adding too much alloy material per unit time.On the contrary,the temperature of the cooling circulating water will rise rapidly when the alloy material is fed too little in unit time,which will result the cold crucible damaged.When the smelting power was 750 kW and the feeding weight was 4 kg/min,the cooling circulation water temperature was less than 50 ℃,the semi-continuous induction smelting of TA1 7 titanium alloy ingot was effectively realized,and the effective utilization rate of energy was about 8.3％.关键词
