摘要： An injection apparatus for a high-speed type thin plate continuous casting machine comprises linear motors (3A, 3B) interposing long sides of a flat nozzle (3), a power source unit for applying predetermined currents having a predetermined frequency to the linear motors (3A, 3B), and linear motor power factor improving capacitors (21) connected between the linear motors (3A, 3B) and the power source unit. A material on the inner walls of the short sides of the flat nozzle (3) is a conductive material to improve an edge effect, additionally, the apparatus is constructed to use a heating operation of the linear motor in heating the nozzle or a molten metal in the nozzle by adequately controlling a frequency or a current of a power supplied to the linear motors.
