Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] In order to improve the problem of uneven cooling of the web of the existing H-shaped tubular crystallizer, the present invention provides an H-shaped tubular mold capable of improving the condensation quality of the web of the H-shaped continuous casting slab. The outer web portion of the working wall Coating or attaching a layer of covering layer made of material with heat insulation function. Regardless of whether the inner surface of the working wall is provided with plating or coating, the covering layer for heat insulation can be coated or attached at the position of the web part of the outer layer of the working surface.

[0025] figure 1 The sectional structure of preferred embodiment one of the present invention is shown, as shown in it, this preferred embodiment one comprises web 1, and the center of web 1 of working...

Abstract

The invention provides an H-shaped tubular mold, which comprises a web, wherein the center of the web of the working wall of the H-shaped tubular mold is provided with a covering layer, and the covering layer is formed by cermet material or metal material, which can resist high temperature and corrosion and the thermal conductivity of which is less than the thermal conductivity of the a material formed into the H-shaped tubular mold. The H-shaped tubular mold not only can prevent the web of a solidified shell from being affected and damaged by the stress produced by rapid chilling, but also can prevent the defect that thermal resistance is uncontrollably increased as the result of ununiform nonuniform air gaps formed by the earlier shrinkage of the initial solidified shell to affect the uniform growth of the solidified shell, so that the heat of the web of the solidified shell can be uniformly dissipated, and thereby therefore the H-shaped tubular mold increases the quality of solidification and prevents severe quality problems, such as cracks.

Description

technical field [0001] The invention relates to an H-shaped tubular crystallizer, more specifically, the invention relates to an H-shaped tubular crystallizer capable of improving the solidification quality of the H-shaped 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 shell with a certain thickness. This process is completed under the continuous and relative motion of the billet shell and the crystallizer wall. Therefore, the crystallizer has good and uniform thermal conductivity and rigidity, so that the solidification process is uniform and stable. [0003] The crystallizer in the prior art includes copper plates or copper tubes and an outer steel structure, and the function of the copper plates or copper tubes is to transfer the heat of molten steel to coolin...
