DEVICE FOR BOTTOM CASTING Russian patent published in 1996 - IPC

FIELD: metallurgy. SUBSTANCE: device has a flat multiple-cavity plate with wave-like side surface, strands for bottom casting, and socket for a sprocket. The plate is provided with runner ingot moulds. The plate is four-cavity and cross-like. The radius of the circumference of the wave-like side surface and radius of the circumference inscribed in the base of the runner should be no more than or equal to the length of the strand. The two adjacent wave-like surfaces are conjugated over the symmetry axis of the plate over the length of the arc that is equal to 0.8-0.9 of the length of the circumference to be conjugated with a conjugation radius of 300-350 mm. There is a through opening for removing waste in the central part of the plate. The plate is provided with locking rods for securing the housing of the runner to the plate. EFFECT: improved design. 3 cl, 3 dwg
