Apparatus for immersion nozzle and nozzle plate immersion and interruption of fire to be used in an apparatus for immersion nozzle

摘要

"Apparatus for immersion, and immersion nozzle and nozzle plate of interruption of fire to be used in an apparatus for immersion nozzle.In an apparatus for immersion nozzle to withstand an immersion nozzle on one side under the flange of the same by a plurality of parallel key plates provided on both sides for the EMPHowl horizontally out and replace an immersion nozzle used for an immersion nozzle again.To ensure a high reliability on the surface of the junction between the immersion nozzle and the inner positioned above the same.The apparatus for immersion nozzle comprising mechanisms for providing thrust pressure independent of each plate key to change continuously a quantity of deflection of a colorPo flexible depending on the position of movement of the immersion nozzle after the exchange of the immersion nozzle and at the same time change of a force of thrust of the nozzle plate immersion caused in the key reu2013 and a structure having a sliding surface of the settlement and support the flexible body formed with a tapered surface in a part of the same.The immersion nozzle to be used here has a surface cu00f3ncava to maintain a sealing element having a depth of 1.0 to 10 mm in a central region of the surface of the junction.A plate of interruption of fire has a thickness greater than a thickness of the flange of the immersion nozzle and a difference in thickness of at least 12 mm.In addition,A top surface of the plate stopping fire has both ends perpendicular to a direction of thrust out with the recess through at least a width of 10 mm and a pDepending on the depth of 12 mm.
