Impact Analysis of Titanium Alloy Blank Folded Layer by Electron Beam Cold Bed Furnace Smelting
The relationship between the folded layer of blank surface of ingots with different dimensions and power or liquid level of electron gun in the 3 200 kW electron beam cold bed furnace smelting was investigated,and formation mechanism of folded layer was clarified.The results indicate that with the constant power,the folded layer amounts at non-overflow side of the blank are increased with the increase of liquid level.Under the common liquid level,the power of electron gun is increased and the folded layer is reduced.During the melting of crystallizer with 1 080 mm,the power of electron gun on liquid surface is(350±10)kW,and the blank is less folded and the energy consumption is the lowest when the liquid level is equal to overflow mouth.During the melting of crystallizer with 1 280 mm,the power of electron gun on liquid surface is(380±10)kW,and the blank is less folded and the casting energy consump-tion is the lowest when the liquid level is equal to overflow mouth.The increase in the width of the mold ensures a decrease in the power density of the electron gun with less folding.
