焦炭

Combustion properties of various coals and solid-gas rates in the blowpipe and combustion properties in the raceway under different condition were calculated.

模型采用附加力的方法处理回旋区内焦炭回旋运动对气流的影响，回旋区大小及回旋区内焦炭燃烧量采用经验公式计算。

It is found that the addition of carbonaceous materials can effectively improve the strength of coke and reduce the reactivity of coke.

结果发现，添加少量炭素物料能够有效地提高焦炭强度并降低焦炭的反应性。

9 kinds of metal oxides are selected, after 0.5%, 1%, 3% and 5% of them based on dry coal quantity are blended into Masteel coal blend, Luling coal and Gujiao coal to carbonize into crucible coke, coke micro strength, structural strength and coke reactivity are measured.

摘 要：选取9种金属氧化物按干煤量0.5%、1%、3%、5%添加到马钢配煤、芦岭煤、古交煤中炼成坩埚焦后，测定焦炭的显微强度、结构强度、焦炭反应性。

The relationship between crystallite structure of coke and coke macroscopic property was studied.

结果表明：焦炭气孔壁最基本单元——微晶结构是影响焦炭宏观性能的最本质因素。

Brief Synopsis: For one and a half years, filmmakers Ulrike Franke and Michael Loeken watch as a gigantic industrial site is dismantled, documenting the stories accompanying its disappearance: how the coke workers in the industrial Ruhr Region experience the arrival and working methods of the Chinese, their feelings upon seeing their pride in their work vanish along what was the most modern coke factory in the world, but also the strain and conflicts the Chinese workers are subjected to during their 60-hour work week far away from home and family, caught between euphoria and doubts about their future.

内容简介：一年半以来，电影摄制者乌尔瑞科·弗兰科和迈克尔·劳肯见证了一块庞大的工业区被夷为平地的过程，拍摄记录了伴随着工业区的消失而发生的故事：鲁尔工业区的焦炭工人怎样经历了中国人的到来和工作方式；工人们对工作的自豪感随着世界上最现代化的焦炭工厂的消失而消逝的感觉；还有背井离乡、每周不得不工作60小时的中国工人，他们的疲劳与抗挣、对未来的喜悦和疑惑。

This paper introduced the relationship of microcrystal structure of coke and its macroscopical properties,and the effects of coal rank and pyrogenation process on microcrystal structure etc.

介绍了焦炭微晶结构与其宏观性质的关联，煤化度及热解过程对微晶结构的影响等，并说明了研究焦炭结构的意义及其发展前景。

Coal tar pitch reduced coke reactivity and increased coke strength after reaction by means of increasing coke optical anisotropy.

煤沥青通过增大焦炭光学组织各向异性程度，使焦炭的反应性降低，反应后强度提高。

This product is widely used in glass kiln vault,recuperator arch,face wall of charging hopper etc.

广泛用于玻璃窑的大碹、蓄热室及投料口前脸墙等部位。焦炭窑炉用硅砖适用于国内、外大型焦炭窑炉。

The charcoal of rice straw was composed of irregular slices and could be compacted tightly. Rice hull charcoal was full of strumae,which was hard to compact,and probably it was the main reason for the higher electrical resistivity.

cm。在 900。℃以上时，焦炭微观结构与温度关系不大，而随秸秆种类不同而差异较大；稻秆焦炭外表面为层叠的不规则薄片；稻壳焦炭外表面为规律排列的瘤状凸起结构，这使得其在一定压力下难以紧密压实，增大了体积电阻率。

Slag viscosity has been tested by viscometer, slag mineral structure has been observed by microscope of high magnification. First discover that UPC is favorable to weeping and taking shape of high titanium-bearing slag, put forward that the mechanism of titanium slag adhering coke is that TiC、TiN and the carbon of coke which is regard as C〓、C〓、 C〓 shape et al weld into chemical bonding compound.

首次发现UPC有利于高钛渣的形成和滴落，提出了钛渣润湿焦炭的机理是碳以C〓、C〓、C〓等形式与TiC、TiN结合成了强力键化合物及固熔体，粘附在焦炭表面的TiC、TiN层随焦炭下降至风口区被再次氧化，而不会大量弥散于渣中影响其粘度。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
