厚板轧机设计
摘要
随着中厚板在造船、建筑、国防、军事等领域的广泛应用，厚板轧制技术在工业领域的重要性日益突出。本次设计就是从生产实际出发，通过下厂实践、调研、查阅大量资料，了解了中厚板生产工艺及国内外发展现状，特别对厚板轧机的组成和结构有了深入了解和认识。本设计的厚板轧机是以2350厚板轧机为基础进行设计。首先根据轧钢机械的设计方法，从工作辊与支承辊的设计计算开始，对厚板轧机的传动系统进行了设计。然后通过轧制力矩的计算推算出主传动电机的功率，并且对所选的电机进行过载和发热校核。同时还对机架、压下系统进行了设计和校核，最后考虑经济和环保的要求进行了分析评价。

Plate Mill Design
Abstract
With the wide application of plate in shipbuilding, construction, defense and military fields, Plate rolling technology have become increasingly importance in the industrial area. The production design is from the actual conditions of the country, understand the plate production process and the development of the status quo at home and abroad, especially have a deeper understanding and awareness for the composition and structure of thick plate rolling mill, by the practice of factory, research, access to large amounts of data. The design of the plate mill is based on 2,350 design. First, design and calculate the work roll and back-up roll and devise the drive system of plate mill in accordance with the design method of rolling mill machinery. Then, calculate the main drive motor power through the rolling moment calculation, and make the load and heat checking to the motor of selected. At the same time also design and check the rack and the system of press. Finally consider the economic and environmental requirements for the analysis and evaluation.
