Crystallization of electromagnetic stirring device

             Product Description              Introduction              Crystallization of electromagnetic blender principle is to use the change of the current to produce strong magnetic field, through the medium of the multilayer cut off, make continuous casting slab of internal metal melting liquid produce flow, through the state of the flow control to improve casting internal organization, component distribution, melting liquid dramatically and surface quality on the purpose.                            Crystal mixing technics predominance              (1)  Don't need to add any grain refinement agent can obtain fine grain organization, eliminate the traditional casting of columnar crystal and bulky branches.            (2) The forming of low temperature (such as aluminum alloy can reduce 120 °C above), and can save the energy.            (3) Die life extension. Solid low temperature semi-solid forming of the size of the shear stress, better than the traditional crystal size of small three orders of magnitude, so the filling smoothly, the heat load small, thermal fatigue strength decline.            (4) To reduce pollution and no safety factor. For homework from high temperature liquid metal environment.            (5) Deformation of small resistance, use small force can realize the homogeneous processing, for difficult-to-machine materials to the forming of easy.            (6) Solidification speed, improve the productivity, process cycle shortens.            (7) Suitable for the computer aided design and manufacturing, improve the production of automation degree.                   Crystal mixing product superiority               (1)  A high quality. For grain refinement, organization distribution even, and the body to reduce shrinkage crack down, hot tendency, except to pass shrinkage matrix, mechanical properties increased significantly.             (2)  The narrow solidification, so forming body size high precision, small machining allowance, net-shape forming.             (3)  Forming alloy scope. The ferroalloy have aluminum, magnesium, zinc, tin, copper, nickel alloy with; Iron base alloy have stainless steel, low alloy steel, etc.             (4)  Manufacturing metal matrix composites. Use of semi-solid metal high viscosity, make the density difference, solid solution for small metal alloy, also can effectively make different materials mixed, make new composite materials.
