EXERGY ANALYSIS OF HEAT TREATMENT OF COLD ROLLED STEEL STRIP

国际能源转换及利用学术会议

作者： Mao Jingmin Zhou Tianxing Mining & Metallurgical department university for Staffand Workers Wuhan Iron & Steel (Group) Corporation Wuhan, Hubei P. R. China

An exergy analysis approach has been introduced in the paper to make an energy analysis of heat treatment system of the bell-annealing furnace for cold rolled steel strip, and a thermal calculation of various kinds of exergy during heat treatment. An explanation on the weak link of usa.e of energy was given. In addition to that, an analysis of exergy loss distribution in the weak link has been made. The result of above analysis provides the basis for any improvement of energy used for technological process.

＜正＞During the course of our investigations to develop directed-C-H activation reactions,two inherent disadvantages of these transformations have emerged as major limitations for widespread application of this technology:only proximate C-H bonds can be activated and directing groups often leave behind undesired chemical "footprints" which could require several extra steps to meet a given synthetic need.

In this paper, a set of partial differential equations is used to describe steady-state natural convection in a vertical annulus filled with porous media unsaturated by refrigerant agent R113. The finite difference method has been adopted to solve the governing equations for two-dimensional field under cylinder coordinate. The calculating results are summarized to show the transport characteristics in the porous media with phase change.

Up to now,we know not much about visceral pain compared with somatic *** has been applied to treat visceral pain for a long time and the underlying mechanism still remains *** purpose of the present study was to investigate the extrasegmental analgesia of electroacupuncture(EA) at orofacial acupoints on visceral pain and its afferent *** pain was induced by intraperitoneal injection of 0.6%acetic acid and was assessed by counting abdominal ***,c-fos expression in the nucleus of the solitary tract(NTS) and paratrigeminal nucleus(PTN) was observed by *** results revealed that EA at Sibai(ST2. acupoints induced c-fos expression in the NTS and *** of EA at ST2.or Jiache(ST6) acupoints or nonacupoints,induced c-fos expression in the PTN and reduced abdominal contractions and c-fos expression in the NTS elicited by acetic ***,pretreatment of EA at Yangbai(GB14) acupoints did *** infraorbital nerve(ION) pretreated with transaction or capsaicin,effects of EA at ST2.on abdominal contractions and c-los expression in the NTS and PTN were dramatically ***,ION pretreated with snake venom had no influence on the EA *** data suggest that orofacial areas-PTN-NTS secondary neural pathway may be involved in the extrasegmental analgesia of EA at orofacial acupoints on visceral pain and C fibers are crucial for the effect.
