MOULD FOR COMPENSATING HEAD WIDTH OF DUMMY BAR

摘要

PURPOSE: A mould for compensating head width of dummy bar is provided to compensate side surface of dummy bar head by installing slider type subsidiary side at both sides of the lower mold part and adjust one dummy bar head to all sizes of casting width by determining slab width using width variable motor of the short side. CONSTITUTION: The mould for compensating head width of dummy bar comprises a mold long side(1-1) on the lower part of which a support(3-1) is formed to support the slider type subsidiary side(3); a slider type subsidiary side(3) which is slid with being rested on the support of the mold long side(1-1), and at the lower side of which a gear teeth surface(3-4) is formed; a mold short side(1) slidingly moved on the upper surface of the slider type subsidiary side(3); a driving motor(3-2) to which a driving gear(3-4) is connected with the driving gear(3-4) being engaged with the gear teeth surface(3-4) formed in the lower part of the slider type subsidiary side(3) to move the slider type subsidiary side(3); and a width variable motor(1-3) for driving a clutch(1-2) connected to a screw rod fixed to the mold short side(1), wherein the slider type subsidiary side(3) is formed of a metallic material having a high thermal conductivity and cooled by cooling water, and wherein the driving motor(3-2) is connected to a distance measuring device(3-5) for calculating the number of revolution of the driving gear(3-4) into a distance value.
