Water cooling channel for large beam blank continuous casting crystallizer

Abstract

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.

Description

technical field [0001] The invention belongs to a device for cooling a casting billet or a mold, in particular to a cooling device for a copper plate of a continuous casting crystallizer of a special-shaped billet. Background technique [0002] As a near-net-shape continuous casting product, special-shaped billet is the best billet for producing H-beams. Rolling H-beams with special-shaped continuous casting billets can significantly reduce production costs and improve the quality of rolled products. The cavity of the special-shaped billet continuous casting crystallizer is "H"-shaped, and the molten steel is continuously poured into the special-shaped billet. During the pouring process, the cooling water takes away the heat of the molten steel in the mold through the cooling water channel dug on the copper plate of the mold, so that the molten steel injected into the mold is continuously cooled and solidified into a shell with a certain thickness, strength and good surface ...
