查询词典 roughing mill

The rebuilding of universal joint for 3200mm four-high roughing mill is introduced and analyzed in this paper.

本文介绍了中厚板厂3200mm四辊粗轧机万向联轴器的改造过程，并对其进行分析，这对于提高中厚板轧机万向联轴器的承载能力具有重要意义。

Because the practical production and theoretical research in the past treat reheating furnace and roughing mill as two separate facilities, which dissevers the continuity of production process and the interaction on energy consumption of the two facilities, even though the minimal energy consumption may be achieved in a single facility, there is no way to guarantee the total energy consumption minimization of the two facilities as a whole.

由于以往实际生产和理论研究均把加热炉和粗轧机作为两个独立的生产设备进行控制，割裂了两者在生产过程上的前后连续性和在生产能耗上的相互影响性，针对每一个设备的控制即使保证了其自身能耗的最小化，也不能实现将这两者作为一个整体来看待的整个热轧生产线的能耗最小化。

As part of the current project, Siemens is resupplying the drives for the roughing mill and sections of the finishing mill.

作为当前项目的一部分，西门子再次为粗扎机和精轧机提供驱动。

Driven by a pair of 40x60 horizontal reversing engines, with a 28 in roughing mill with a pair of 48x54 in direct-acting horizontal reversing engines, and a 28 in finishing mill with similar 50x54 engines.

驱动由40x60对横向扭转发动机，与同在粗加工中的48x54直接作用的横向扭转发动机，并在整理类似50x54发动机厂28对轧机28。

The heating process and rolling process of slab are very important procedures in hot rolling production line. Reheating furnace should heat the slab to the temperature distribution that is needed by the rolling technology of roughing mill, and roughing mill should roll the slab into the product with the desired dimension. Reheating furnace and roughing mill are two main energy-consuming facilities in hot rolling production line.

钢坯的加热过程和轧制过程是热轧生产线上非常重要的两个生产环节，加热炉需要将钢坯加热到满足粗轧机轧制工艺要求的温度分布，粗轧机则需要根据生产要求将加热好的钢坯轧制成指定规格的产品，这两者是热轧生产线上的主要耗能设备。

In order to solve these problems, a new integrated optimizing control strategy based on production is presented, which forms a closed loop between reheating furnace and roughing mill, making the production of reheating furnace meet the requirement of roughing mill.

针对这些问题，提出了基于生产目标的热轧过程集成优化控制策略，将加热炉和粗轧机组成一个有机的闭环系统，使加热炉的生产能够满足粗轧机轧制生产的需要，通过对热轧过程的建模和优化，达到节能降耗、保障轧制生产安全、优化生产过程的目的。

In order to solve these problems, a new integrated optimizing control strategy based on production is presented, which forms a closed loop between reheating furnace and roughing mill, making the production of reheating furnace meet the requirement of roughing mill. In this way, energy consumption can be reduced, the production process can be optimized, and the production security of rolling process can be quaranted at the same time.

针对这些问题，提出了基于生产目标的热轧过程集成优化控制策略，将加热炉和粗轧机组成一个有机的闭环系统，使加热炉的生产能够满足粗轧机轧制生产的需要，通过对热轧过程的建模和优化，达到节能降耗、保障轧制生产安全、优化生产过程的目的。

In hot rolling process, reheating furnace and roughing mill are controlled separately in general, and as a subsequent equipment of reheating furnace, roughing mill can not feed useful rolling information back to reheating furnace in time, so that reheating furnace can not heat slabs according to the requirement of roughing mill.

在热轧过程中，加热炉和粗轧机基本上是各自独立控制的，粗轧机作为加热炉的后续设备不能及时地把轧制信息反馈给加热炉，因而导致加热炉不能按照粗轧机的生产要求去完成钢坯的加热过程。

The new roughing mill rolling stand will be integrated into the automation environment of the heavy-plate rolling mill which has already been implemented according to the Siroll PM concept.

该新粗扎机厂轧钢架将统一到已经根据Siroll PM概念实施的厚钢板轧钢厂的自动化环境中。

In order to roll round billets with accurate roughing shapes by a three-high roughing mill and stabilize production, a flexible pass design method was used to optimize the traditional conjugate pass through the distortion design of the bottom, side wall and pressure difference of the pass, realizing the application of the conjugate round pass on the three-roll mill.

为轧制料形尺寸准确的圆料、稳定生产，采用变通孔型设计方法对共轭孔型进行优化设计，通过对共轭孔型槽底、侧壁、压力差的变形设计，实现了共轭圆孔型在三辊粗轧机上的应用，轧槽咬钢顺利，成品圆料容易控制，完全满足后续工序的要求，同时减小了轧线的轧制事故，单套轧辊的轧制量可提高60%以上，取得了良好的经济效益。
