简要介绍了我国首台自己研制开发的精密四辊压延机。该机是在普通压延机的基础上,对压延机的三大结构:轴承结构、调距结构及密封结构作了较大的技术革新。另外,为提高压延精度,增设了预负荷装置、轴交叉装置、反弯曲装置。通过5年的生产实践,证明其在结构和性能上达到了精密压延机的要求,我国将可以实现用国产精密压延机取代进口产品。
Briefly introduced our country’s first self-developed precision four-roll calender. The machine is based on the ordinary calender, the calender of the three major structures: bearing structure, pitch structure and sealing structure made a greater technological innovation. In addition, to improve calendering accuracy, additional pre-load device, shaft cross-device, anti-bending device. Through five years of production practice, to prove its structure and performance to meet the requirements of precision calender, China will be able to achieve with domestic precision calender to replace imported products.
