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。

Heating billet temperature cannot be detected in the hearth. Only by detecting temperatures of the stove side or hearth with estimation from mere experience could lead to great error on the measurement of billet temperature and affect the quality of post-processing accordingly; Overheating also exists in the heating process, and the quality of product is sway by overheating oxidation. Though infrared thermoscope is used to detect the temperature of billet when it is taken out of the stove, precision is still affected because of the oxide layer on the surface.

燃气与空气的配气量比例，一般通过人工调节，未实现按加热条件自动动态调节；无法在炉膛内检测被加热钢材的温度，只能通过检测炉壁或炉膛温度，再凭经验估计钢材温度，结果是钢板温度误差大，影响后续加工质量；钢材加热存在表面过烧现象，有时表面烧损、氧化严重，影响产品质量；尽管钢材出炉时，可用红外线测温仪来进行钢材表面温度检测，但因钢材表面存在氧化层，也影响钢材温度检测精度。
