湘钢2号高炉倒扣C型冷却壁损坏的应对

针对湘钢2号高炉炉身上部倒扣冷却壁的损坏,采取了一系列的应对措施,主要是高炉操作制度上的调整、降料线喷涂和压入造衬维护.     

风口衬套的研制与应用

1 前言 湘钢现有3座高炉(1、2、3号高炉容积分别为1000、750、1000m~3),1号高炉大修后于1996年7月开炉,2号高炉于1987年4月投产,3号高炉于1994年5月投产。在3号高炉建成前,湘钢只有1号、2号两座     

湘钢4号高炉强化冶炼实践

对湘钢4号高炉强化冶炼实践进行了总结。在入炉原燃料质量不断劣化的情况下,通过采取大风量操作,下部活跃炉缸、上部开放两道煤气流,控制合理操作炉型等措施,高炉维持了长周期稳定,减缓了原燃料对高炉的影响,实现了高利用系数、低燃料比的生产目标。     

湘钢4号高炉炉缸侧壁温度异常升高后的护炉实践

对湘钢4号高炉炉缸侧壁温度异常升高的原因及护炉措施进行了总结。4号高炉炉缸侵蚀的主要原因在于,当生产条件发生变化时各项操作制度没有随之做出调整,操作制度与生产条件不匹配。通过采取强化铁口维护、钛矿护炉、调整送风及布料制度、增加冷却强度、降低冶炼强度等措施,8个月后炉缸温度逐渐下降至正常水平,高炉生产趋于稳定。     

湘钢1号高炉碱金属行为

对湘钢1号高炉碱金属行为进行实际调查和理论分析,发现高炉中的碱金属主要是由铁矿石和焦炭带入的,碱金属的排出主要是通过炉渣.碱金属在高炉内的循环富集,给高炉带来一系列不利影响.结合湘钢高炉的实际生产情况,提出防治高炉碱害的措施.     

湘钢1号高炉大修改造后的生产实践

湘钢1号高炉扩容改造后,达产经历了三个阶段。回顾了三个阶段的生产实践,总结了1号高炉精料、提高风温与喷煤量、优化操作、新技术的应用等达产的主要措施。

湘钢2号高炉强化冶炼生产实践

对湘钢2号高炉强化冶炼生产实践进行了总结。通过采取提高富氧率、提高顶压、稳定好风温、确定合理高炉操作制度等一系列强化冶炼措施,使得技术经济指标得到明显改善。     

Helping in 36 U.S. cities.

A series of experiments examined the relationship of urbanism to helping. Six types of helping behaviors were studied in a cross-sample of 36 small, medium, and large cities across the United States. The relationship of helping to a series of statistics reflecting the demographic, social, environmental, and economic characteristics of these communities was then examined. The strongest and most consistent predictor of overall helping was population density. There were significant correlations between economic indicators and helping in 3 situations. Helping in some situations also tended to be negatively related to violent crime rates and to environmental problems. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

R.A.P.I.D. Reconstructive alternative for prosthetics in implant dentistry

As stated at the outset, this technique is not for every case. Each case must be selected with great care, consideration and careful planning. In concert with observing the Implant Lighthouses, this technique can produce a successful case. It can be done to save time, without compromising the prescribed techniques and quality.     

Master resilience training in the U.S. Army.

The U.S. Army Master Resilience Trainer (MRT) course, which provides face-to-face resilience training, is one of the foundational pillars of the Comprehensive Soldier Fitness program. The 10-day MRT course is the foundation for training resilience skills to sergeants and for teaching sergeants how to teach these skills to their soldiers. The curriculum is based on materials developed by the University of Pennsylvania, the Penn Resilience Program (PRP), and other empirically validated work in the field of positive psychology. This “train the trainer model” is the main vehicle for the dissemination of MRT concepts to the entire force. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Pharmacokinetics in clinical practice. 2. Applications

The pharmacokinetic concepts introduced and defined in a preceding article are now applied to the management of drug therapy for the individual patient. The factors that affect the time course of drug concentrations in plasma produced by repetitive administration include the dosing rate, total clearance, biologic half-life, and systemic availability of the drug. A clinical pharmacokinetics service can monitor drug concentrations in biologic fluids, design individualized drug-dosing regimens, and carry out pharmacokinetic diagnostic work-ups to help determine the reasons for a patient's unusual response to drug therapy.
