The experiment and the research indicate that:(1) Through the Hot-Continuous-Rolling production technics under small reduction ratio of 4.04 and 5.08, the rectangular continuous-casting billet of 235×265mm can be used to produce big size steel stick of Φ140mm and Φ 125mm whose macrostructure and mechanical properties meet the standards, this technics is viable;(2) This rolling technics can make the deformation penetrate to the center of the billet by low temperture and low velocity and big roller diameter and large reduction quantity at every pass and optimum design and arrangement of rollers, which is the key of Hot-Continuous-Rolling technics under small reduction ratio;(3) The sending technics used in Xining Special Steel Co.,Ltd can not use waste-heat of billet adequately, but the sensitive temperature section of A1N or sulphides or inclusions separating out is avoided, creating a favorablecondition for insuring good surface quality of final rolled steel;(4) The Hot-Continuous-Rolling technics under small reduction ratio has a close relationship with the billet quality control and the hot sending process control and the cooling control after rolling.

通过实验研究表明：(1) 235×265mm矩形连铸坯分别采用4.04和5.08的小压缩比热连轧生产工艺，所生产的Φ140mm和Φ125mm的大规格棒材，其低倍组织和机械性能均符合标准要求，该工艺是可行的；(2)本实验所采取的低温低速、大辊径大道次压下量轧制工艺加上轧辊孔型的优化设计与配置，可以使加工变形渗透到铸坯的中心，这一点是实现小压缩比热连轧生产工艺的关键；(3)西宁特钢在红送过程中虽然铸坯余热未能得到充分的利用，但是有效地避开了A1N、硫化物的析出及夹杂物偏析的敏感温度区，为保证最终轧材良好的表面质量创造了有利的条件；(4)小压缩比热连轧生产与铸坯质量控制，热送过程控制以及轧后冷却控制密不可分。

New multi—objectives function (including mill stand longitudinal stiffness, distribution coefficient of loaded pressure between rolls, weight of mill stand, rolling power, rolls loaded gap profile changeability of bending force, transverse mill stand stiffness of bending force, transverse mill stand stiffness of rolling load) multi—constraints (including rolls strength, spindle strength, backup roll bearing load, minimum rollable gauge, roll surface temperature rise) rolls system parameters optimization model of four—high cold strip mill is established, and programme for mill structural illustration creation on the platform of AutoCad designs is compiled. With this as basis, rolls system parameters of Yichang thin strip corporation's 1219 cold mill are calculated using SUMT (subsequent unconstrained minimization technology).

本文建立了以板形和板凸度控制特性为目标的四辊轧机多目标函数（包括轧机纵向刚度、辊间压力分布系数、轧机重量、功率、弯辊力对轧机辊缝形状改变能力、对弯辊力的横向刚度、对轧制力的横向刚度）、多约束条件（包括轧辊强度、接轴强度、支承辊轴承负荷、最小可轧厚度、轧辊温升等）的辊系参数优化模型，以此模型为基础，利用惩罚函数法计算了益昌薄板公司1219冷轧机辊系参数，编制了AutoCAD平台下的轧机结构示意图自动图形软件。
