What is more, the utility model is easy to be controlled and can improve the effective utilization rate of steel fluid and economize the cost.
Description
Technical field
The utility model relates to a kind of Ampere force pressure amorphous pocket builder, is that the liquid towards metal applies Ampere force and regulates pressure by control system between nozzle and nozzle bag, realizes pressure spray band.
Background technology
Non-crystaline amorphous metal is to adopt super quench solidification technology, temperature at the alloy melt more than 1200 ℃ by high cooldown rate (10
6℃/S) cooling fast, the amorphous ribbon of about 18～35 μ m of formation thickness.This kind band can be made into nanocrystalline high permeability material, high saturable core material and antitheft material and brazing material etc.The uniformity of aspect dimensional accuracy controls such as the surface property of this material and thickness has significant impact to the serviceability of material, general amorphous pocket builder as shown in Figure 1, it comprises intermediate frequency furnace 1, nozzle bag 2, chill roll 4, stripper 6, and there is a nozzle 3 nozzle bag 2 belows.The alloy melting that intermediate frequency furnace 1 will be used to make band becomes liquid, pours in the nozzle bag 2, and liquid alloy falls within on the chill roll 4 rapidly through nozzle 3 that cooling forms amorphous ribbon 5, peels off by stripper 6.
The thickness of amorphous ribbon depends on the rotating speed of pocket builder chill roll, nozzle 3 and the distance of chill roll 4 and the liquid level h in the nozzle bag.Liquid level has just determined the pressure of spray band, and the pressure of spray band not only influences the thickness of amorphous ribbon, but also influences the surface quality of band.According to modern times super chilling system band technology, it is to realize easily that the distance of the rotating speed of chill roll, nozzle and chill roll keeps constant.Constant according to Fig. 1 if will control liquid level h, still there is not good solution at present.
Fig. 2 is the pressure amorphous spray band machine of trial production at present, and the characteristics of this spray band machine are that nozzle bag and smelting furnace unite two into one, and crucible 21 is induction furnaces, and the crucible outside is an induction coil 22.One nozzle group valve 23 is arranged on the nozzle 3.This crucible seals, and adds inert nitrogen gas protection in fusion process, when alloy melting liquid reaches certain temperature and begins the spray band, increase the pressure of inert gas, and pressure changes with liquid level variation in the crucible, thereby keeps constant pressure spray band.The advantage of this spray band machine is the pressure that has increased the spray band, the amorphous band that spray is thin can be realized and surface quality can be improved, weak point is because nozzle bag and induction furnace are one, and seal, so it is limited once to spray the band amount, the consumption of materials such as nozzle is very big, has improved the cost of spray band significantly.Keep the control system more complicated of constant pressure spray band, the precision of control is not high yet, and operability is not strong.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of Ampere force pressure amorphous pocket builder is provided.
Technical solution of the present utility model is: a kind of Ampere force pressure amorphous pocket builder increases magnetic field and the electric current vertical with magnetic field between nozzle bag and nozzle.
Adopt the Ampere force pressure techniques to realize amorphous system band, can overcome the shortcoming of existing amorphous pocket builder, maximize favourable factors and minimize unfavourable ones and bring following advantage:
(1) flow-control is accurate, and is adjustable continuously.When Ampere force is enough big, has just ignored liquid level in the nozzle bag and changed influence, thereby just realized constant voltage spray band spray band pressure.
(2) the nozzle bag does not need sealing, and smelting furnace can be constantly replenishes molten steel in the nozzle bag, therefore only otherwise disturbed by other factors such as nozzle damage, can realize the disposable very big system band amount of finishing.
(3) production process and production status are highly stable, and repeatability is fine, can realize amorphous band longitudinal thickness deviation less than 2 μ m, but and spray thickness be the ultra-thin band of 18-20 μ m.
(4) the control system reflection rapidly.
(5) this equipment is easy to control, and can improve the effective rate of utilization of molten steel, saves cost.Outstanding behaviours is aspect two, on the one hand owing to adopt Ampere force pressure system band, compare with general traditional pocket builder, reduced the quantity of bad band, improved effective lumber recovery, on the other hand because the direction of Ampere force has determined the flow direction of molten steel, therefore damage at nozzle, when stopping up or making the end of band process, can molten steel oppositely be moved, reclaim and remain molten steel.

The specific embodiment
The operation principle of Ampere force pressure amorphous pocket builder:
During the work of Ampere force pressure amorphous pocket builder, in the molten steel in the smelting furnace is poured into the nozzle bag, liquid metal in the nozzle bag is subjected to the acting in conjunction in the magnetic field (B) of the electric current (I) of y axle negative direction and x axle positive direction, this both direction is orthogonal, according to the ampere Left Hand Rule, live metal in magnetic field will be subjected to the electromagnetic force of x axle positive direction, i.e. Ampere force.As long as intermediate frequency furnace provides enough molten steel to replenish to the nozzle bag, liquid metal will constantly flow to x axle positive direction, control by magnetic field and electric current realizes that constant compression force makes liquid metal produce directed moving, and finishes whole system band process by nozzle and chill roll.
Referring to Fig. 3, Fig. 4, Fig. 5.The utility model is to increase magnetic field and the electric current vertical with magnetic field between nozzle bag 2 and nozzle 3, and magnetic field is produced by a magnet 7, and electric current is inserted by electrode 8.Like this liquid metal in the nozzle bag has just been produced the effect of a power, this power acts directly on and makes it to produce directed moving on the liquid metal, thereby has realized pressure spray band.
The nozzle bag can be installed in the side of chill roll, as shown in Figure 3, also can be installed in the top of chill roll, as shown in Figure 4.
