Title: Method for preventing clogging of small-diameter nozzle
Inventor: KARASHIMA KAZUO
IPC: B22D41/50
Filed: 1986-06-02
Abstract: PURPOSE:To effectively prevent nozzle clogging, more particularly nozzle clogging in an initial period of casting by installing the nozzle having a prescribed inside diameter or below so as to raise the top edge thereof from the base of a tundish in which the nozzle is embedded. CONSTITUTION:The inflow of the molten metal cooled by contact with the base 4 of the tundish in an initial period of pouring is prevented and the clogging of the nozzle in the extreme initial period is prevented by positioning the top edge of the nozzle 1 having <=20mm inside diameter higher than the base 4. The temp drop by the heat transfer from the neighborhood of the top end of the nozzle 1 to the base 4 is decreased and the clogging is prevented even in the subsequent stationary period. Furthermore, the nozzle 1 is embedded into the base 4 in such a manner that the top edge thereof rises above the base. As a result, a nozzle support 2 plays the role of a gate and contributes to the improvement of cleanliness. In addition, such installation is also effective in preventing the nozzle clogging by the deposition of nonmetallic inclusions.
