Description of the development:
()
Magnetodynamic mixer MDN-6h-3.0 is designed for heating and casting iron foundries in the pulsing lines flask and flaskless molding, in chill and centrifugal machines, continuous casting and forging liquid. It is also recommended as a mixer for aging and heating iron. Magnetodynamic mixer consists of cast iron crucible fitted with induction magnetodynamic unit. The crucible is closed by a cover, a window cleaning slag and metal trough for topping up. Induction unit containing a welded body, the two inductor electromagnet toe drain metal. These components are mounted on the frame, which rests on the ground. The mixer is equipped with a mechanism for stabilizing the initial level of metal casting. Lining multilayer mixer. Working lining layer is made of a refractory mass MK-88 and MK-90 domestic production. Term resistance lining in the working layer of gray iron casting up to 12 months of continuous operation of the mixer. The principle of operation of the mixer is based on the effects of electric and magnetic fields in the liquid metal. In operation, the mixer is poured into the crucible initially liquid metal which fills the channels of the induction unit. On winding inductors include the power supply voltage. In this case, the electric current creates a channel under the action of which the heating of the metal. Heat is transferred from the channels into the crucible by the circulation of the metal through the channels. When the voltage on the winding of the electromagnet there is the electromagnetic field at the site is accommodate poles of the electromagnet interacts with an electric current in the metal and creates an electromagnetic force. Under the influence of this force the liquid metal is driven. Depending on the polarity of energization to the coil of the electromagnet electromagnetic force can be directed towards the drain or towards the toe of the crucible. The first option determines the mode switching voltage "Casting", the second - "mixing". Mixer Mode - continuous. The liquid iron is poured into the mixer bucket 1.0-3.0 m. In outside change the mixer is on low power, providing long-term storage of the liquid metal at 1200-12500S. During filling the forms of electromagnetic power to the systems set so as to provide a technologically required temperature and mass flow rate of iron. Metal casting process controlled by the operator. Casting is done automatically on the time during which a given portion of metal flows. Time dispensing a dose is set on the control unit for each shape depending on the metal content. The operator can adjust the fill time and the feed rate of the metal into the mold. The control circuit also provides a manual pouring iron into molds. Developed by two samples magnetodynamic mixer: one with the toe drain - to fill the cast iron hearth in one and two drain socks - supply of metal in two metallopremnika. The latest version of the induction unit is equipped with two electromagnets with independent power supplies.
