Embodiment 1

[0015] A side sealing plate applied to twin-roll casting disclosed in Embodiment 1 of the present invention, such as figure 1 As shown, the graphite flow distribution device 2 is preheated to 680 degrees Celsius. The metal to be cast and rolled is aluminum alloy. The copper strip 6 is set for implementing the trace method, and has nothing to do with the invention of this application document.

[0016] Shown in the embodiment of the present invention figure 1 Among them, the working surface 3 of the simple side sealing plate is provided with patterns, and the pattern is a laser-processed prism array structure, and the pattern units are arranged at intervals behind the working surface 3 of the side sealing plate, forming several discontinuous protrusions.

[0017] Shown in the embodiment of the present invention figure 1 Among them, the working surface of the side sealing plate is still as clean as new after working for at most 30 seconds, and the long-term use can be estimat...

Abstract

The invention belongs to the field of double-roller cast rolling, and particularly relates to a side sealing plate applied to double-roller cast rolling. Nodulation on the working face of the side sealing plate of the double-roller cast-rolling molten pool is not beneficial to process stability, and at present, reduction of resistance borne by cast-rolled metal passing through the working face of the side sealing plate and / or change of the wettability of the working face of the side sealing plate is a crucial method. The invention provides a side sealing plate applied to double-roller cast rolling.

Description

technical field [0001] The invention belongs to the technical field of twin-roll casting and rolling, and in particular relates to a molten pool side sealing plate applied to twin-roll casting and rolling. Background technique [0002] During the twin-roll casting and rolling process, the working surface of the side sealing plate is in contact with the metal being cast and rolled in the molten pool, and nodules will occur. The appearance and growth of nodules are undesirable for enterprises. According to the actual production experience of the enterprise, the appearance of nodules may be related to the broken belt accident. [0003] The main factors that contribute to the nodulation of the side sealing plate are: the material of the side sealing plate, the physical and chemical properties of the metal being cast and rolled, the working time, the state of the reaction layer (temperature, velocity, boundary layer thickness, reaction concentration, etc.), the wettability of th...
