H-shaped combined crystallizer

Abstract

The invention provides an H-shaped combined crystallizer which comprises two flange wide plates and two narrow plates, wherein each of the flange wide plates comprises a web plate formed by protruding in the middle and flanges positioned on two sides of the web plate; the web plates are used for limiting and forming web plate parts of H-shaped casting blanks when casting the blanks; the flanges and the narrow plates coact when blanks are cast so as to limit and form flange parts of the H-shaped casting blanks; the flanges comprise winglets and flange inclined surface parts positioned between the web plates and the winglets; the narrow plates are arranged inside two opposite winglets, wherein a plurality of water pipes are arranged on the outer sides of working walls of the narrow plates, and a plurality of water pipes are arranged on the outer sides of working walls of the web plates and the flanges along the length direction of the flange wide plates; and the sectional areas of the water pipes close to center lines of the web plates are the smallest. The H-shaped combined crystallizer provided by the invention prevents center parts of the web plates from being influenced and damaged by stress caused by rapid cooling, so that the web plates of blank casings are cooled evenly, and the solidification quality of the cast blanks is improved.

Description

technical field [0001] The application relates to an H-type combined crystallizer, more specifically, the application relates to an H-type combined mold capable of improving the solidification quality of the H-type slab web. Background technique [0002] The crystallizer is a water-cooled copper mold, which is an extremely important core component of the continuous casting machine. The molten steel is cooled in the crystallizer, initially solidified and formed, and has a certain thickness of the billet shell. This process is completed under the continuous and relative movement of the billet shell and the mold wall, so the mold has good and uniform thermal conductivity and rigidity. In order to make the solidification process uniform and stable. [0003] The crystallizer of prior art is made up of copper plate or copper tube and the steel structure outside, and the effect of copper plate or copper tube is to transfer the heat of molten steel to cooling water. There are gene...
