As a is small and makes the ratio a/8 less than 2.2, the melt shape and electromagnetic pressure for confining and shaping are determined not only by magnetic flux density B but also by melt thickness a, electromagnetic parameter μγ and current frequency f. In this paper, an equation used to calculate electromagnetic pressure acting on 'thin plate-form melt' is brought forward. The equation gives a precise relationship between electromagnetic pressure factor p and melt thickness a, electromagnetic parameter μγ and current frequency f. 展开更多

Dual frequency electromagnetic confinement and shaping (EMCS) makes it easier to adjust and control the shaping temperature field and magnetic field than single frequency EMCS. The shaping stability and temperature field of the dual frequency EMCS were investigated. The results indicate that to shape stably, the upper liquid/solid interface should be in appropriate position and the lower liquid/solid interface must be above the critical position. The current of heating induction coil and the drawing speed of sample affect the shaping temperature and its peak position, while the current of the shaping induction coil only influences the shaping temperature. During EMCS, the speed of shaped sample affects not the height of the molten metal, but the temperature of molten metal. The height of the molten metal for steady shaping was about 15 mm in the experimental conditions. Several stainless steel plate-like parts with high width to thickness ratio (≥3.5) and directional structure were obtained. 展开更多

Significant electromagnetic pulses (EMP) can be generated by the intensive laser irradiating solid targets in inertial confinement fusion (ICF). To evaluate the EMP intensity and distribution in and outside the laser chamber, we designed and fabricated a discone antenna with ultra-wide bands of over 10 GHz. The return loss (Sn parameter) of this antenna was below -10 dB and could even achieve under -30 dB at 3.1 GHz. The EMP intensity in this study at 80 cm and 40 cm away from the target chamber center (TCC) reached 400 kV/m and 2000 kV/m. The current results are expected to offer preliminary information to study physics regarding laser plasma interactions and will also lay experimental foundation for EMI shielding design to protect various diagnostics. 展开更多

Liquid metal(LM)has become an emerging material paradigm in the electromagnetic interference shielding field owing to its excellent electrical conductivity.However,the processing of lightweight bulk LM composites with finite package without leakage is still a great challenge,due to high surface tension and pump-out issues of LM.Here,a novel confined thermal expansion strategy based on expandable microsphere(EM)is proposed to develop a new class of LM-based monoliths with 3D continuous conductive network.The EM/LM monolith(EM/LMm)presents outstanding performance of lightweight like metallic aerogel(0.104 g cm^(-1)),high strength(3.43 MPa),super elasticity(90%strain),as well as excellent tailor ability and recyclability,rely on its unique gas-filled closed-cellular structure and refined LM network.Moreover,the assembled highly conducting EM/LMm exhibits a recorded shielding effectiveness(98.7 dB)over a broad frequency range of 8.2-40 GHz among reported LM-based composites at an ultra-low content of LM,and demonstrates excellent electromagnetic sealing capacity in practical electronics.The ternary EM/LM/Ni monoliths fabricated by the same approach could be promising universal design principles for multifunctional LM composites,and applicable in magnetic responsive actuator. 展开更多

The 3-dimension numerical simulation study on the electromagnetic dam used in the twin roll caster has been performed by using the edge element method. It was found that the materials and structures of the roll collars have great influence on the distribution of the magnetic flux density, eddy current density and the electromagnetic force in the molten pool. The conductive collars make the magnetic flux density decreased in the molten pool, but it also makes the magnetic force more uniformly, and the force in the low part of the molten pool where needs greater force have increased some what. The conductive collars make the EMD device more effective than the nonconductive collars. 展开更多

Electromagnetic casting technology became maturity and gained wide applications in steel-making and aluminum casting, which is still immature in copper casting. Electromagnetic continuous casting with soft-contact mold was employed to produce copper round billet with high density. At the same time, in this paper, a mathematical model of the electromagnetic field in the soft-contact mold was built on the base of the vector potential method, then it was solved by the ANSYS commercial FEM software. Current and frequency was altered in the course of operation so as to find out how they effect the magnetic field distributing. Its accuracy was verified by the measurement result of the electromagnetic field in the mold without billet. By this model, the effect of excitation current on field was gained, which set up a certainty foundation for more research. 展开更多

Electromagnetic pulses(EMPs)with high intensity and frequency bandwidth can be generated during the intensive laser irradiating solid targets in inertial confinement fusion(ICF).To shield the EMPs radiation and hence protect various diagnostics in and outside the target chamber,we designed a multi-layer structure material to shield the EMFs and demonstrate experimentally and numerically shielding performance of the material structure.The thickness of the multi-layer structure material has a great influence on the EMPs shielding.It is shown that,with the increase of the material thickness,the better shielding performance is obtained,and the material structure with polytetrafluoroethyIene of 0.5 mm,copper of 0.4 mm and lead of 2.4 mm reduces 448 times compared the maximum value of EMPs voltage to that without shielded.The design of multilayer structure material for EMPs shielding provides a promising way to reduce EMPs radiation,which is extremely useful for the diagnostics protection and signal processing in ICF. 展开更多

A bound state formalism derived from a fermion-boson symmetric Lagrangian has been used to calculate the nucleon masses, the charge neutrality of the neutron, the magnetic moments and the electromagnetic form factor ratios μpGEp/GMpand μnGEn/GMn. A quantitative description is obtained, assuming a mixing of a scalar bound state of 3(f f¯)fstructure with its corresponding vector (f f¯)fstate (f indicating massless elementary fermions). Only a few parameters are needed, mainly fixed by energy and momentum conservation. The nucleon stability is explained by an extra binding in the confinement potential, negative for electric and positive for magnetic binding of the proton, and opposite for the neutron. The stronger electric extra binding of the proton allows a decay of the neutron to proton and electron. 展开更多

To design a power source system and mold for electromagnetic soft-contact continuous casting process and to theoretically estimate the heat losses from the charges and the system power, the effect of structure parameters on system power and magnetic flux density distribution was calculated using finite element method. The results show that as for electromagnetic soft-contact continuous casting system with partial-segment type mold, the power consumption is much more than that with a full-segment type mold; about 62% of electric power is dissipated in the mold, and the effective acting range of magnetic field is relatively narrow. Optimizing mold structure is a crucial measure of remarkably reducing mold power consumption and saving electric energy. Increasing slit number, width, and length can remarkably increase the magnetic flux density in the mold and can reduce the electric energy consumption. Among structure parameters, slit number and slit width are relatively more effective to reduce energy consumption. For a round billet electromagnetic continuous casting system with diameter of 178 ram, the reasonable slit number, width, and length are about 24--32, 0. 5--1.0 mm, and 160 mm, respectively. 展开更多

The paper introduces the research and new development on soft-contacting electromagnetic continuous casting in Baosteel.At the year of 2008,Baosteel successfully completed the carbon steel SCEMCC industrial experiment in a 6-strand curved type round billet caster.At the year of 2011,Baosteel selected another 3-strand curved billet caster. Baosteel successfully developed the SCEMCC mold for the first time to do the industrial production experiment for stainless steel round billet continuous casting.Then,in the same stainless steel caster,the square billet SCEMCC mold was successfully developed too.And at the beginning of the year 2012,the square billet SCEMCC of SUS304 and SUS303Cu was implemented up to now.It was proved the machine system was reliable for the long time production.The industrial experimental result shows the soft-contacting electromagnetic continuous casting can reduce the depth of oscillation mark from about 0.7mm to near zero.The SCEMCC billets without surface grinding were transferred to mill tubes,of which the quality is satisfied. 展开更多

A two-dimensional axisymmetric finite element model for stress distribution of billet in electromagnetic soft-contact continuous casting mould was established by a two-way coupled method.The contact state between solidified shell and mould was described to simulate the thermal-mechanical behaviors in the soft-contact mould.And the effects of frequencies and currents on stress distribution of billet had been discussed and analyzed.The results show that the equivalent stress of initial solidification shell both at its outer and inner surface decreases but at the bottom the equivalent stress of two sides of shell both increases when the current intensity is 1600 A,and the frequency is 20 kHz,compared with the status of conventional continuous casting. 展开更多
