Abstract(59) PDF(1)
Abstract:
According to the characteristic of adjusting width by erect roll at PZH Steel, the uneven deformation rule of slab during erect and horizontal rolling was analyzed by finite element simulation on base of MSC. Marc software. The effect of rolling process conditions on the width and size of head and t...
Diffusion Welding of Titanium Alloy and Stainless Steel With Electroplated Nanometer Ni Interlayer
Huang Wenzhan, Sheng Guangmin, Qin Bin, Yuan Xinjian, Li Cong, Qiu Shaoyu
2006, 27(3): 21-25.
Abstract(67) PDF(3)
Abstract:
The diffusion welding of titanium alloy TA17 and stainless steel 0Cr18Ni9Ti with electroplated nanometer Ni interlayer was investigated. The elements distribution was analyzed by energy dispersion spec-trometry. The results show that the interlayer can prevent the elements interdiffusion of Ti, V, A...

2006, 27(3): 26-30,37.
Abstract(61) PDF(1)
Abstract:
A self-cleaning ceramic loaded nano-TiO2 was prepared by sol-gel process. The crystal structure and the crystal size of TiO2 were characterized by XRD. The effect of the precursor's concentration and calcining heat on the ceramic's hydrophilicity and degradation of methyl orange under UV-light were ...
Research on Secondary Cooling Technologies for Continuous Bloom Casting
Chen Yong, Yang Subo, Li Jianquan, Chen Lu:Ying
2006, 27(3): 31-37.
Abstract(48) PDF(2)
Abstract:
The secondary cooling scheme previous employed in continuous bloom caster was of following inadaptabilities for production of rail steel, such as the density of the secondary cooling and water distribution in secondary cooling zones. Therefore, the secondary cooling control scheme suitable for rail ...

Study of Removing Tin Techniques for Reflow Conductor Roll
Fu Hanguang, Yan Lifen
2006, 27(3): 44-47,54.
Abstract(73) PDF(1)
Abstract:
Adhering tin is the main cause that reflow conductor roll abates which works in the electroplating tin line （ETL）. Removing the tin by means of chemical method is the important measures prolonging the servicing life of conductor roll. The tin remover whose main compositions are NaOH and KOH and assi...

2006, 27(3): 48-54.
Abstract(92) PDF(3)
Abstract:
The simulation tests of rail contact fatigue damage in varied railways were carried out at a professional test machine. The results show the rail wear decreases meanwhile the contact fatigue damage increases with the train velocity increase when the velocity is below 200 km/h, and both of them decre...
Study on Continuous Cooling Transformation of Vanadium Microalloyed Steel P510L
Yu Wanhua, Zhou Liquan, Han Jingtao, Zhang Zhongping, Liu Yong, She Guangfu
2006, 27(3): 55-59.
