Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of vacuum arc remelting furnace of the present invention.
Embodiment
In order to can better the technical scheme of the present invention be understood, below by specifically embodiment and be described in detail by reference to the accompanying drawings:
Refer to Fig. 1, a kind of vacuum arc remelting furnace of the present invention, comprise movable stove head 1 and static melting station 6.
By supporting, mechanism 8 is connected movable stove head 1 with driving support 3.
Conductive material bar 2 runs through the central authorities of movable stove head 1 from top to bottom, and is connected with movable stove head 1. Conductive material bar 2 is connected with driving support 3 simultaneously.
Static melting station 6 comprises copper crystallizer 4 and stainless steel water jacket 5.
Copper crystallizer 4 is movably placed in stainless steel water jacket 5, and stainless steel water jacket 5 is fixed on the lower section of travelling oven head 1.
Stainless steel water jacket 5 is barrel-shaped; Stainless steel water jacket 5 top is provided with a water coolant water inlet; The bottom of stainless steel water jacket 5 is provided with a water coolant flowing water Valve.
The outer surface of stainless steel water jacket 5 is wound with cable 51. Stainless steel water jacket 5 is connected with rectifier power system and auxiliary water system 7. Cable 51 is single core nylon sheath cable. Cable 51 is adopt duplex winding coil winding to carry out coiling at the winding method of the outer surface of stainless steel water jacket 5.
Before starting the vacuum arc remelting furnace of the present invention, first electrode is put into copper crystallizer 4. It is good that special steel and steel alloy electrode are poured into a mould under air or under vacuum before being; For active metal as titanium, electrode is suppressed by titanium sponge or by electron beam furnace, plasma heating furnace melting out in advance. By driving, the traction of support 3 is placed to copper crystallizer 4 to movable stove head 1, and the vacuum melting room of upper formation one sealing, electrode is clamped on conductive material bar 2, and conductive material bar 2 can promote electrode.
Once vacuum melting room is formed, so that it may activate direct supply. Controlling System regulates the high current arc between consumable electrode (negative pole) and copper crystallizer 4 base plate automatically, forms rapidly a metal pool on base plate. To be kept accurate arc length between smelting electrode and metal pool (arc gap), and set up the melting rate that can control. Metal molten drop is dripped into molten bath by arc gap, and is exposed to the arc region of vacuum environment and extreme temperatures. To eliminate insoluble gas, volatilization residual impurity, improve oxide compound degree of cleaning. Adopting copper crystallizer 4 to be placed in stainless steel water jacket 5, the metal pool that metal molten drop is formed solidifies with oriented approach. If molten speed and welding arc control must be got well, this kind of controlled directional freeze will prevent serious segregation and reduce microsegregation, thus improve the performance solidifying spindle. Arrive the melting later stage, owing to having controlled heat-sealing top well, can consumption by what greatly increase product.
The cable 51 of stainless steel water jacket 5 outer surface adopts duplex winding coil winding, and the way utilizing winding in parallel to reduce loss pressure drop carries out coiling. Design theory is according to researching and developing based on Biot-Savart law. In magnetostatics, Biot-Savart law is (English: Biot-SavartLaw) to describe the magnetic field that current elements is put arbitrarily P place and excited in space.
The size of magnetic induction density dB that law text description: current elements Idl produces at space point P place is directly proportional to the size of current elements Idl, it is directly proportional to the sine of the angle between current elements Idl place place to the position vector and current elements Idl of P point, and square being inversely proportional to of the distance put with current elements Idl to P. Biot-Savart law is caused by the experiment of H.C. oersted, and this experiment shows, the reactive force of magnetic pole is transverse force by long straight current carrying conductor. In order to disclose electric current to the general quantitatively rule of magnetic pole reactive force, J.B. Biot and F. Sa cut down you and think that the reactive force of magnetic pole also should be perpendicular to current elements and the plane of magnetic pole formation by current elements, are namely also transverse forces. They bend current carrying conductor to the experiment of the reactive force of magnetic pole by long direct sum, have drawn reactive force and the relation at Distance geometry bending angle.
Having had above theoretical basis, we are according to practical situation, first draw the magnetic field power size needed for agitation of molten steel, calculate voltage according to magnetic field power, electric current, finally determine cable 51 specification.
The present invention adopts electrode weighing system data to improve process control precision; Smelting furnace adopts the proprietary technology of coaxial conductive design, decreases to maximum degree the stirring in uncontrollable magnetic field; The control of complete computerize ensure that the consistence of quality product, and operation of equipment simultaneously is very convenient.
Those of ordinary skill in the art will be appreciated that, above embodiment is only used to the present invention is described, and not it is used as limitation of the invention, as long as in the spirit of the present invention, to the change of the above embodiment, modification all by the Claims scope dropping on the present invention.
