The design is simply introduced the development of production technology of the heavy plate in a whole design, the disparity gap of the home and abroad and the heavy plate means in this design ,and adopt the new technology. The main include: 2 step-beam furnace, reversal device high-pressure-water descaling unit, 1 four-roll reservable rough mill, as well as various appurtenances. According to the designed annual capacity, and considering market prospects of the products, the products’ scheme and metal balance were designed reasonably. The rolling system includes: press-down system, velocity system and temperature system. Then, the roll force was calculated; the electromotor load and the roll strength were checked. the electromotor load and the roll strength were checked.And maked out a scientific and reasonable heavy medium plate design scheme . A plant layout drawing was also accomplished in the design, An English paper and its translation by author were attached to the thesis. The features of the designed workshop include: of high strength of products and mechanical property of the products, adoption of advanced processing technology, and environmental protection consideration. The plant achieves high production in lower consumption. Key words: heavy plate; rolling system; ship plate 摘要 1 Abstract II 第一章 引言 1 1.1国内外宽厚板发展状况 1 1.1.1国外宽厚板发展概况 1 1.1.2 国外厚板轧机的发展 1 1.1.3轧制技术的发展现状 5 1.2 我国宽厚板发展概况 8 1.2.1宽厚板的生产
