Abstract

The invention discloses a twin-roll thin-strip casting side sealing plate. The side sealing plate comprises a panel containing boron nitride materials and a base plate with aluminum-silicon thermal insulation materials, wherein the panel and the base plate are fixed through adhesion. The invention also discloses a method for manufacturing the side sealing plate. As the thermal conductivity of thebase plate of the side sealing plate is much less than that of the panel, the heat of the base plate is not easy to dissipate, and heat-insulation effect is improved so as to ensure the quality of theside parts of strip steel. Moreover, equal thermal expansion coefficients of the base plate and the panel can avoid twist deformation or cracking after the side sealing plate is heated. Modified silicone resin binder resistant to high temperature not only enhances bonding strength, but also plays a role in thermal insulation.

Description

technical field [0001] The invention relates to a twin-roll thin strip continuous casting process, and more specifically relates to a twin-roll thin strip continuous casting side sealing plate and a manufacturing method thereof. Background technique [0002] Different from the traditional continuous casting technology, the twin-roll thin strip continuous casting technology does not need to go through multiple hot rolling processes, which can greatly simplify the thin strip production process and reduce equipment investment. see figure 1 As shown, the twin-roll thin strip continuous casting is mainly by pouring molten steel directly into a molten pool surrounded by two crystallization rolls 1 and side sealing plates 10 that rotate relatively and can be cooled rapidly. It is cooled and solidified toward the surface, and then forms a solidified shell and grows gradually, and then is squeezed together at the smallest roll gap between the two crystallization rolls 1, thereby for...
