PURPOSE: A device for forced opening an injection port of furnace of a casting ladle is provided to increase a working time, to improve the cost effectiveness, and to maintain a quality of products constantly. CONSTITUTION: The device for forced opening an injection port(120) of a furnace of a casting ladle is composed of an ejection hole(11), a base brick(10), an injection wall brick(20), a push brick(30), a fixed plate(40), and a fluid pressure pipe(50). The ejection hole penetrates the center of a body in the inner surface of the injection port of the furnace of the casting ladle. The base brick including space(12) in the inner surface of the ejection hole more than one is installed. The injection wall brick has an injection hole for filling a furnace-ejection-conduit closed filler in the ejection port of the base block. The push brick is installed to crush filler on moving up and down by a fluid cylinder in a space of the base brick. The fixed plate is connected by fastening a bolt to the base brick, the wall brick, and the push brick on the bottom of the casting ladle. The fluid pressure pipe is installed to make the push brick up and down by supplying a working fluid on the fixed plate.
