The invention belongs to a cooling
casting blank or
casting mould device and relates to a
water cooling channel for a large beam blank
continuous casting crystallizer,,and particularly to a
copper plate cooling device for a beam blank
continuous casting crystallizer. The
copper plate
cooling channel is characterized in that: a web
water gap, a R angle
water gap, a bevel
water gap, a
flange inner angle water hole and a
flange top water hole are formed on a broadside
copper plate according to the characteristics of the copper plate shape and heat face
heat flux; the water gaps without corners are distributed uniformly, and the water gaps at R angle are dense, and few water holes are arranged at concave corners; and a cooling water tank is arranged outside a narrow side copper plate. The copper plate
cooling channel has the advantages that cooling water channels are arranged in areas, the number of cooling water channels is reduced, water gap
diameter is reduced, and
processing quantity is reduced; the water gaps are arranged reasonably, temperature
peak value at the R angle is eliminated, the
temperature gradient is reduced, the cooling strength of the
flange top is weakened, the overall temperature of the copper plate tends to be uniform, the
working environment of the copper plate and blank
heat transmission condition are improved, the
cooling effect is good, and water is saved; deformation and abrasion of the copper plate are reduced, and service life is prolonged; the surface quality of blanks is remarkably improved, the cogging yield is improved, and
continuous casting production can be performed smoothly.
