Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] see figure 1 , a slab continuous casting machine crystallizer copper plate, mainly uses a wave-shaped copper plate to facilitate the flow of liquid mold slag in the crystallizer into the gap between the copper plate and the billet shell, filling the air gap, so that the heat conduction between the billet shell and the copper plate It can be completed according to the design requirements to lubricate the copper plate wall and reduce the wear of the billet shell on the copper plate surface. The billet shell is always kept close to the copper plate wall under the static pressure of the molten steel. Due to the wavy surface, it can prevent shrinkage in the direction of the narrow surface.

[0028] 1) The surface of the copper plate...

Abstract

The invention discloses a slab caster crystallizer copper plate and a using method of the crystallizer copper plate. A wavy surface copper plate is mainly adopted, so that liquid covering slag in thecrystallizer conveniently flows into a gap between the copper plate and a blank shell, an air gap is filled, heat conduction between the blank shell and the copper plate can be completed according todesign requirements, the wall of the copper plate is lubricated, and abrasion of the blank shell to the surface of the copper plate is reduced. The blank shell is always kept tightly attached to the wall of the copper plate under the static pressure of molten steel, and due to the wavy surface, shrinkage in the narrow face direction can be prevented.

Description

technical field [0001] The invention belongs to the technical field of metallurgical equipment, and in particular relates to a mold copper plate of a slab continuous casting machine and a using method thereof. Background technique [0002] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0003] As the core component of the continuous casting machine, the mold of the slab continuous casting machine has a very direct impact on the production of the casting machine and the quality of the slab. Molten steel is cast into the crystallizer and cooled with the inner wall of the mold to form a billet shell. The billet shell at the corner part has heat transfer in both directions of the narrow surface and the wide copper plate, and the cooling intensity is high, causing it to shrink to the side with high cooling intensity. , forming distortions inside the mold, causing quality defects at the corne...
