Small semi-solid electromagnetic stirrer

           System advantages

          In order to convenient for laboratory research, in the sensor’s the relationship between semi-solid metal stress and the dendrite. This system adopts the voltage, frequency, stirring time continuously adjustable, made the semi-solid metal liquid loading condition be clear at a glance. Simple operation control interface, the man-machine interface simple and clear, all operations on the control panel can be done immediately.

           Although the semisolid continuous casting technology haven't reached the level of large-scale industrial application, But in the existing experimental research and small-scale production has shown a strong vitality. Synthesizing the relevant research both at home and abroad is not hard to see, semi-solid casting technology in the following areas has a bright application prospect:

          (1) High alloy and difficult deformation material forming

          High alloy materials and difficult deformation material forming has been a difficult problem in the field of material processing. The semisolid continuous casting billet in the semi-solid temperature has the similar advantage of the liquid molding directly, for high alloy material no segregation, no defects casting and difficult deformation material forming smoothly found a feasible technical route. The research team researches show that, usually think not of forging white iron and high manganese steel, After made of semi-solid casting billet, in the semi-solid temperature molding thickness 2 mm, a length of more than 100 mm complex parts. Therefore, the semisolid continuous casting in terms of difficult deformation material molding with billet production will have a brilliant future.

          (2)The development of a new generation steel and iron material

          Now all countries in the world in the super steel research, our country also has been started important basic planning project“A new generation of iron and steel materials research”. A new generation of iron and steel material requires high clean, ultrafine, ultra-high strength, at the same time also has the potential of large scale application. In order to achieve this goal, will need to adopt continuous casting technology to made blank, while the existing continuous casting billet are widespread columnar crystal area is big, the macro segregation seriously flawed. The semisolid continuous casting billet tiny grains, less of macrosegregation advantage will no doubt be less for a new generation of iron and steel material blocking a worth exploring the technical route.

          (3)Composite material blocking and molding

          Composite materials are a rookie of materials science, but so far, the preparation of composite materials and its large-scale timber is still a problem. The semisolid continuous casting in solve this problem will have a brilliant future, It has been confirmed by numerous test institute.

          In a word, The semisolid continuous casting technology in high alloy material, difficult deformation, fine crystal homogenizing steel materials and high value-added new materials forming has a unique technical advantages.

          Operating principle

          Electromagnetic stirring method using the electromagnetic induction in half a liquid metal solidification of the induced current, induced current under the action of magnetic field makes the metal solid liquid slurry agitation fiercely, make traditional dendritic structure into non dendritic mixing organization.
