板坯连铸横移机设计
摘要
连续铸钢的出现和发展,大大地缩短了工艺流程,极大地简化了轧钢生产的工艺系统,与传统的模铸坯-初轧开坯相比、省去了脱模、整模、均热初轧和连轧开坯等一系列工序和对应的设备。这不仅明显降低了能耗,并且大大节省了设备投资和生产投资。
鞍钢集团公司炼钢厂的连铸技术已达到国内外先进水平,连铸的特点是将高温钢水连续不断的浇注成具有一定断面形状和一定尺寸规格的铸坯,并具有了提高综合成材率、降低能耗、产品的均一性好、质量高、易于实现机械化自动化等显著特点。但是随着事成竞争的逐渐激烈,板坯连铸机的优化与改良就成了提高板坯质量、占领市场的重要环节。因此,本人通过大量的实地调研、现场学习、仔细询问观看,对连铸机相关设备(板坯横移机)的结构与性能有了一个深入的认识。并运用自己所学的知识,从动力学、机械原理、经济学等诸多方面对连铸机中的板坯横移机进行设计,使其更加适用于新市场的形势。
本设计还对板坯横移机的传动系统的各参数进行了设计计算,同时也对主要部件进行了强度分析与校核,对其中的一部分零部件进行了改进。

Slab continuous casting and transverse moving design
Abstracts
The emergence and development of continuous casting steel greatly shortened process, greatly simplifies the system of steel rolling production process, from the traditional mold casting - blooming sufficiently compared, eliminating the demoulding, at the beginning of the whole mold, soaking rolling and rolling breakdown and a series of process and the corresponding equipment. This not only significantly reduces the energy consumption, and greatly saves equipment investment and production.
Anshan iron and steel (group) corporation steel continuous casting technology has reached the advanced level at home and abroad, the characteristics of the continuous casting is the high temperature molten steel continuous casting into a certain section shape and a certain size of slab, and with the increase yield, reduce energy consumption, product uniformity good, high quality and easy to implement and other significant characteristics of mechanization automation. Into the increasingly fierce competition, but as a matter of slab continuous casting machine optimization and improvement has become an important link in improve the quality of the slab, occupy the market. Therefore, I through a lot of field investigation, field study, ask to watch carefully, for continuous casting machine related equipment (slab structure and properties of horizontal moving) have an in-depth understanding of. And use their learned knowledge, from many aspects, such as dynamics, mechanical principles, economics to design of the slab continuous caster horizontal moving, to make it more suitable for new market situation.
This design also the parameters of the transmission system of slab transverse moving has carried on the design and calculation, but also on the main components of strength analysis and check, on the part of parts was improved.
Keywords: continuous casting, improved, the quality of the slab, the slab transverse moving
