Scrap steel will be loaded into steelmaking furnace and molten after sieving and dewetting . if the chemical composition and target temperature of molten steel are satisfied , the molten steel will be poured into ladle and conveyed to continuous caster , then be made as billet with specified length 废钢铁经筛选去湿，装入炼钢炉冶炼融化成钢水，当达到要求的化学成分及温度目标值时，将钢水倒入钢水包，送至连铸机，浇铸成定尺长度的钢坯
Device of casting etc . nickel cobalt alloy of copper electroplate technology in succession , it adopts the electroplating craft of the assembling type , the electroplating system of the low stress , according to the user s needs , can be constructed and plate different kinds of coppers 两国联合企业millcraft sms services的连铸机结晶器铜板镍钴合金电镀技术，它采用组装式的电镀工艺，低应力的电镀体系，根据用户需求，可对不同类型铜板进行施镀。
The bloom project of pangang will bring large economic and social benefits ! the space of new technology and technic applied in pan gang should be speed up . this also would become effectively typical way or module for automation system applied in pan gang 攀钢上“大方坯连铸机”项目，将具有很好的经济和社会效益，同时加速了新技术、新工艺在攀钢应用的步伐，也为自动化控制系统在攀钢企业推广、实施提供了一套较为有效的、可供借鉴的方法和模式。
After modification , main technologica and economic indexes have been improved and sequence casting has been realized , finished products of plain carbon and low - alloy grades through secondary annealing eliminated and billet hot delivery and charging primarily realized , which develops the modification of slab ccm at xinyu iron & steel co . ltd 改造后,方坯连铸机主要技术经济指标得到了提高,并实现了转炉钢全连铸,消灭了普钢、低合金钢二火线材;消灭了二次化铁;初步实现了方坯热装热送;引发了新钢公司板坯机改造。
When the data of logistics in current process are used for input of simulating logistics in future 100 % continuous casting process , supply of hot metal from iron - making process may not satisfy the needs of 100 % continuous casting on raw materials . because planning scheme in continuous casting process depends greatly on smelting scheme in convertor vessel , it is important for operator to balance raw materials supply , smelting and casting in order to realize the scheme of 100 % continuous casting . when some equipment are work abnormally , mixer of hot metal and lf furnace can be used for logistics buffer 用攀钢炼钢生产数据对仿真软件系统进行的测试和仿真研究结果表明：仿真系统的随机数发生算法可以实现对作业时间的依分布随机抽取；在相似的输入条件下，仿真结果与实际生产物流的时间分布规律基本吻合，达到了仿真软件设计的预期目标；若以攀钢提钒炼钢厂现工艺的铁水输入作为全连铸后的输入条件，则现工艺的物料供应能力可能难以满足全连铸生产的要求；连铸机的连浇计划对转炉炉次计划的编制有很高的要求，合理安排来料、炼钢与浇铸三者间的物流平衡关系将是保证全连铸作业的重要条件；当出现设备异常情况时，可以利用混铁炉与lf炉站前等待作为物流缓冲池，通过延长系统的平均物流时间来缓解因设备检修和故障等扰动所造成的影响，确保生产的顺利进行。
To increase the rate of hitting the grade of liquid steel based on match between converter and continuos caster in capacity is considered as a promising way to improve process control and make production cost - efficient at steel making division . based on lgmis and the model of process - control of converters , the factors , which impact to the hit ratio of grade of liquid steel , have been investigated in details . the influence of quality and availability of primary raw materials , such as hot metal , semi - steel and mixture hot metal and semi - steel , on quality of liquid steel has investigated 本文结合攀钢转炉炼钢工艺现状及全连铸对钢水质量的要求，从改进炼钢过程质量控制的角度，以转炉连铸机炉机匹配条件下提高钢种炼成率为目标，在现有lgmis系统和转炉炼钢过程静态控制模型的基础上，详细分析了攀钢转炉炼钢的钢种炼成率以及影响攀钢转炉炼钢的钢种炼成率的因素，分析了转炉炼钢主原料（铁水、半钢、混合铁水）的质量和物流条件对攀钢炼钢过程质量的影响，提出了通过控制转炉炼钢主原料质量和物流条件改进炼钢过程质量控制的策略。
Oscillator mechanism with four - eccentric axes is widely used in modem continuous casting machine . with the increase of operation speeds of the machine , elastic vibrations of the machine parts became much obviously . in order to design the machine reasonably , the complex dynamic property of the system must be studied deeply 结晶器四偏心式振动机构是大型连铸机上广泛采用的一种振动装置，随着拉速的提高，其弹性振动效应非常明显，对其复杂弹性动力学性能进行深入研究是合理设计该系统的基础。
With engaged in person who cast crystallization device electroplate copper repair and new product make in succession , crystallization device always becomes and makes , overhaul of the equipments and reorganize and outfit , refractory material of casting etc . and person who melt hollow particle cast , spend , protect dreg production , storage transportation , etc 是以从事连铸机结晶器电镀铜板修复及新品制作结晶器总成制造连铸机设备检修与整备耐火材料及预熔型空心颗粒连铸用保护渣生产仓储运输等为主体的综合性集体企业。
