铜闪速熔炼三年长周期生产实践

为了持续提高技经指标,提高生产效率,降低生产成本,江西铜业股份有限公司贵溪冶炼厂开创了三年长周期生产实践。针对贵冶熔炼二系统闪速炉在三年长周期生产实践中干燥机系统、排烟系统和闪速炉系统出现的生产瓶颈问题,查找原因并提出解决办法。生产实践表明,随着入炉高杂质原料占比越来越高,生产仍能均衡稳定,主要技术经济指标持续进步。     

燃气脉冲除尘装置在余热锅炉的应用

随着产能的提升,贵冶1#闪速炉余热锅炉的热负荷在不断上升,其出口烟气温度也在逐年攀升,曾一度超过设计值,给锅炉系统的安全运行带来隐患。引入燃气脉冲除尘装置,可提高锅炉对流部的除尘效率,从根本上解决了锅炉出口烟气温度偏高的问题,使锅炉系统较好地满足了高装入量下的生产要求。     

贵溪冶炼厂2~#闪速炉排烟系统的管理

贵溪冶炼厂2#闪速炉在投产以来的几年,排烟系统在生产过程中碰到一系列的难题,贵冶生产技术人员通过改造前闪速炉排烟系统存在的问题进行系统的分析及基础上,并通过对闪速炉锅炉、闪速炉电收尘进行改造,同时对排烟系统存在的瓶颈进行分析,通过技术改造和日常系统的管理,闪速炉排烟系统运行状况逐步走向稳定状态,确保了生产运行稳定。各项参数、指标达到了历史最好水平。     

贵冶闪速炉余热锅炉改造

随着贵冶三期挖潜改造工程的实施,余热锅炉对流部入口出现了烟尘粘结,严重影响了闪速炉的正常作业,利用2003年年度大修时机,对闪速炉余热锅炉进行了相应的改造,取得了很好的效果。     

贵冶闪速炉余热锅炉辐射部改造

三期改造后,闪速炉余热锅炉辐射部出现了烟尘粘结,影响了闪速炉的正常作业。贵冶参考余热锅炉对流部的改造经验,利用2005年和2007年年度大修时机,对辐射部进行了两次改造,取得了良好的效果。     

闪速炉余热锅炉技改质量控制要点

闪速炉余热锅炉在熔炼车间工艺流程中具有不可替代的作用,其日常检修作业量大且影响生产。因此贵冶拟在2010年二系统年修期间对被大块砸坏部位进行全面检修,并对辐射部、对流部局部进行改造。根据贵冶二系统闪速炉余热锅炉改造完善技术要求,对吊装、集箱组装、焊接、压力试验等施工重点质量控制点进行分析,保证了完善改造工程如期完成。

论从实践理解世界的物质性和自然世界的先在性

马克思主义唯物论是一种物本主义形态的唯物论,还是一种超越物本主义形态、从实践理解世界的本质相关问题的实践的唯物主义的唯物论?这是一个我们必须搞清楚的有关马克思主义唯物论的本质规定性和精神实质的重大问题.在考察物本主义的唯物论及其思维方式的局限性的基础上,揭示了马克思主义唯物论是现代的、实践的唯物主义,并重点研讨了马克思主义唯物论关于从实践理解世界的物质性和自然世界的先在性的原理,以期为马克思主义唯物论进一步阐明人类世界的实践性原理奠定基础.     

Effect of cyproheptadine on the ultrastructure of the neurons of the arcuate nucleus in the hypothalamus of the rat

The data are presented on changes in the rat arcuate nuclear neuron ultrastructure after using cyproheptadine (peritol, Egyt Pharmaceutical Works, Hungary) in a water suspension at a dose of 20 mg/kg once daily during 7 successive days and twice a day within 10 days. It was shown that cyproheptadine decreases the functional activity of the arcuate nuclear neurons, depending on the total amount of the drug used. Cyproheptadine-induced inhibition of the forming neurohormone release from neurons is likely to be one of the mechanisms of its therapeutic effect in Itsenko-Cushing's disease.     

Characteristics of the sympathetic innervation of the nictitating membrane and of the vasculature of the nose and tongue of the cat

Vasomotor responses from the nasal mucosa and tongue, and contractions of the nictitating membrane, were recorded on stimulation of the cervical sympathetic or internal carotid nerves. Preganglionic sympathetic nerve fibres which elicited a membrane response possessed a lower threshold than those which evoked nasal vasoconstriction, while the latter displayed a lower threshold than fibres which evoked tongue vasoconstriction. The sympathetic vasodilator fibres to the tongue whose activity was revealed after alpha-receptor blockade, had a similar threshold to the vasoconstrictor fibres. Membrane contraction, nasal vasoconstriction and occasionally tongue vasoconstriction could be evoked by stimulating the internal carotid nerve. The postganglionic fibres innervating the nasal mucosa had a similar threshold to those of the nictitating membrane, which may indicate that there are small myelinated fibres innervating the mucosa. The preganglionic compound nerve action potential had four major components, S1-S4. S1, S2 and usually S3 fibres were associated with membrane contraction; S2, S3 and sometimes S1 fibres were associated with nasal vasoconstriction; and S3, usually S2 and occasionally S1 fibres were associated with vasoconstriction in the tongue. It is concluded that each of these three groups of nerve fibres, but not S4 fibres, may include fibres associated functionally with the three effectors. There was a considerable difference between the relative amplitude of the responses of the three effectors elicited by stimulation of the cervical sympathetic nerve at frequencies between 0.2 and 2 Hz. Vasoconstrictor responses were relatively larger than membrane contractions suggesting differences in the mechanisms of neurotransmission at the neuroeffector junctions.
