全连铸 meaning in Chinese
sequence casting
Examples
- However , it is still a long way to optimize the scheduling in production , increase the hit ratio of steel grade because of existing amount of scheduling based on expert scheduling
但仍然存在依靠人为经验组织生产,在协调组织生产和提高品种炼成率方面还存在潜力。特别是实现全连铸后，生产协调问题更为重要。 - 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。 - A timed petri nets model for simulating the production scheduling in present process and future continuos casting process has been built . finally , the model has been programming into software based on object - oriented software design methodology with visual basic6 . 0 program language . some of case tests have been carried out based on plant practice in steel making division of panzhihua iron and steel corporation the production planning sub - system of lg - idss can be used for making , optimizing and adjusting on - going plan of steel making production in the plant
本文在分析国内外决策支持系统发展现状的基础上，构建了攀钢提钒炼钢厂生产管理智能决策支持系统（ lg - idss ）的框架；重点研究了lg - idss中的生产计划子系统，建立了适合炼钢厂现阶段和全连铸生产条件下炼钢连铸生产调度仿真的时间petri网模型，最后采用面向对象的软件设计技术编写了软件，并以攀钢炼钢厂生产组织情况为例进行了仿真、模拟。
