摘要： Provided is a manufacturing method of a recycled plate for a sliding nozzle, which is capable of repairing damage of a plate used for a sliding nozzle to extend an endurance period and widens a range of the used plate as a target for recycling. The manufacturing method of the recycled plate performs, on a plate used for the sliding nozzle, recycling processing including impregnating a matrix of the plate that is formed by a refractory brick with liquid containing at least one of tar and pitch, heating the plate impregnated with the liquid to remove a volatile component, grinding a surface of the plate after having been impregnated with the liquid and heated, and bonding a plate material to one surface of the plate after having been grinded.

摘要： A sliding gate device includes a fixed plate fixed to a molten steel container, a sliding plate for opening/closing a nozzle hole, a sliding device moving a case holding the sliding plate, and a contact pressure control mechanism switching between a contact pressure applied state and a no-contact-pressure applied state for the fixed plate and the sliding plate. The contact pressure control mechanism has a support bar member supported to move relative to the fixed plate, a joining block tool switching between a joined state where the support bar member and the case cooperate with each other by mounting the joining block tool therebetween, and a joining-released state where the support bar member and the case do not cooperate with each other by dismounting the joining block tool, and a spring member generating a force applying a contact pressure according to a position of the support bar member.

摘要： An immersion-nozzle replacement apparatus includes a guide, and a pressing keyboard row. The guide supports two immersion nozzles, a foremost immersion nozzle and a rear immersion nozzle. The guide includes two rows supporting the immersion nozzles via the lower face in the flange. The pressing keyboard row, which is provided in the rows of the guide, includes first keyboards pressing the foremost immersion nozzle via the lower face in the flange. The immersion-nozzle replacement apparatus pushes out the foremost immersion nozzle horizontally with the rear immersion nozzle, and puts the rear immersion nozzle on the pressing keyboard rows. The guide further includes an additionally-pressing keyboard row following a rear end of the pressing keyboard rows, and including a second keyboard pressing the rear immersion nozzle via the lower face in the flange before pushing out the foremost immersion nozzle.
