Abstract
The pure titanium of electron beam cold hearth melting stove melting does a method for the head of ingot, and the present invention starts 1 ~ No. 7 EB rifle, increases the amount of hydrogen, makes EB rifle electric current be about 1A; By buttons such as deflection, rotations, regulate often the figure of rifle, make it in corresponding position; Begin to cool down 40min, drop-down 40mm; Then strengthen the electric current of 6, No. 7 rifles to 5A, continue 5min, the surface of the titanium liquid solidified in crystallizer is melted completely; The electric current of slow increasing 1 ~ No. 4 rifle is 9A, and the electric current of No. 5 rifles is 4.5A figure is P3 ∮ 3; Thus beginning normal smelting, do head and terminate.The invention has the beneficial effects as follows, the lumber recovery of titanium ingot can be improved, improve surface quality, thus reduce production cost.The head of ingot made is smooth, zero defect, lays a solid foundation for producing high-quality titanium ingot.In addition, the lumber recovery of titanium ingot is also significantly increased.
Description
Technical field
The invention belongs to the smelting process technical field of the pure titanium ingot of EB stove melting.
Background technology
The electron beam cold hearth melting stove that KV-Titan company of Ukraine produces what draw ingot system to adopt is that the ingot-guiding head of 60mm × 200mm down draws titanium ingot in the middle of crystallizer.The smooth quality of the head of ingot directly has influence on lumber recovery and the sinuousness thereof of whole titanium ingot.What is more likely can cause flow measurement affect vacuum to drawing ingot room to destroy water-cooled tube thus cause melting to carry out.Due to current existing employing do a method can cause ingot-guiding head melt bad, titanium liquid solidify instantaneously have little time secondary melt, the unequal factor of power division, thus cause the head of ingot to be distorted, tip, thus the lumber recovery having influence on whole spindle, cause increasing considerably of cost.
Summary of the invention
Object of the present invention is exactly the defect existed to overcome above-mentioned prior art, is not changing in equipment situation, improves the lumber recovery of titanium ingot, improves surface quality, thus reduces production cost.
The pure titanium of electron beam cold hearth melting stove melting does a method for the head of ingot, and feature of the present invention is, by regulating 7, the properly distributed of the power of electron beam gun and figure thereof is obtained smooth, the flawless titanium head of ingot; The steps include:
1) when vacuum is extracted into 3.0 × 10-3torr, the hydrogen pure with drying purges 7 rifles, thus ensures that whole tracheae is unobstructed, and exists without other gas, thus ensures the stability of rifle;
2) on, the figure of 1 ~ No. 7 rifle is adjusted to P1 ∮ 1, and the focusing up and down of all rifles is adjusted to 0.5, simultaneously and by pattern reduction (1 ~ No. 4 X-axis reduces, and No. 5 rifle X, Y-axis reduce, and 6, No. 7 Y-axis reduce) to close to a line;
3) start 1 ~ No. 7 EB rifle, increase the amount of hydrogen, make EB rifle electric current be about 1A.By buttons such as deflection, rotations, regulate often the figure of rifle, (1 ~ No. 5 rifle will make light beam beat to expect inside cold bed the specified location on (scull) in corresponding position to make it.6, the part of overlap by overlapping for a light beam part, and will be beaten on ingot-guiding head by No. 7 rifles, thus melts ingot-guiding head);
4) continue the electric current of increasing 1 ~ No. 5 rifle, make the electric current of 1 ~ No. 5 rifle be 4.5A, thus the material (scull) inside cold bed is all melted;
5) left and right input speed is adjusted to 4mm/min; Melt the titanium sponge in material frame; The figure of No. 6 rifles will be adjusted to P6 ∮ 2, electric current is adjusted to 3A simultaneously, and is moved on ingot-guiding head by ∮ 2 figure and melt ingot-guiding head fast, thoroughly, and No. 6 rifle figures are adjusted to P1 ∮ 1 after melting by ingot-guiding head; The figure of No. 5 rifles is adjusted to P3 ∮ 3, allows the titanium sponge liquid melted in cold bed flow into crystallizer; And with 6, No. 7 electron beam gun, the titanium flowed down liquefaction is opened fast; When on bracket in crystallizer very thin be paved with one deck titanium liquid after, the figure of No. 5 rifles is adjusted to P2 ∮ 2, and stops charging;
6) fast the figure of 6, No. 7 rifles is filled up whole crystallizer, electric current is adjusted to 5A simultaneously, thus make that the titanium liquid of inflow crystallizer is uniformly distributed, ingot-guiding head and titanium liquid well merges, simultaneously and water coolant slowly form the head of ingot;
7) be adjusted to P3 ∮ 3 at the secondary figure by No. 5 rifles, make the titanium liquid in cold bed again flow into crystallizer, the electric current of 1 ~ No. 4 rifle is adjusted to 8A, the electric current of No. 5 rifles is adjusted to 4.5A simultaneously; Left and right input speed is adjusted to 8 mm/min;
8), when the titanium liquid in device to be crystallized reaches spacing, the electric current reducing by 1 ~ No. 4 rifle is 2A, and the figure of No. 5 rifles is adjusted to P1 ∮ 1; The electric current of 6, No. 7 rifles is adjusted to 0A simultaneously;
9) 40min is begun to cool down, drop-down 40mm; Then strengthen the electric current of 6, No. 7 rifles to 5A, continue 5min, the surface of the titanium liquid solidified in crystallizer is melted completely; The electric current of slow increasing 1 ~ No. 4 rifle is 9A, and the electric current of No. 5 rifles is 4.5A figure is P3 ∮ 3; Thus beginning normal smelting, do head and terminate.
The invention has the beneficial effects as follows, the lumber recovery of titanium ingot can be improved, improve surface quality, thus reduce production cost.The head of ingot made is smooth, zero defect, lays a solid foundation for producing high-quality titanium ingot.In addition, the lumber recovery of titanium ingot is also significantly increased.
