Composite side sealing plate and preparation method thereof
The invention relates to the technical field of double-roller thin-strip casting and rolling, and particularly discloses a composite side sealing plate applied to a double-roller thin-strip casting and rolling process, and the heat conductivity coefficient, the elastic modulus and the linear expansion coefficient of the composite side sealing plate are changed in a gradient mode in the thickness direction; or the heat conductivity coefficient, the elastic modulus and the linear expansion coefficient of the composite side sealing plate change in a gradient mode in the height direction. Therefore, when the composite side sealing plate is applied to a double-roller thin-strip casting and rolling process, the maximum thermal stress generated by the composite side sealing plate can be effectively reduced, the situation that the composite side sealing plate cracks or even fractures due to the interaction of the thermal stress and supporting force is avoided, and the service life of the composite side sealing plate is prolonged.
本发明涉及双辊薄带铸轧技术领域，具体公开了一种应用于双辊薄带铸轧工艺的复合侧封板，复合侧封板的导热系数、弹性模量和线膨胀系数沿厚度方向梯度变化；或复合侧封板的导热系数、弹性模量和线膨胀系数沿高度方向梯度变化。由此，将该复合侧封板应用于双辊薄带铸轧工艺时，能够有效降低复合侧封板产生的最大热应力，避免由于热应力与支撑力的相互作用导致复合侧封板出现裂纹甚至断裂，提高复合侧封板的使用寿命。
