High temperature fatigue deformation properties of INCONEL 718 alloy Progress
tureonFatiguePropertiesofAlloy718, AcollectionofAugust, 2004,17 (4) :345-349. papersfromthe4thInternationalSymposiumonSuperalloys718, Received Date: 2007.06.05 ten }_{·}_{·}_{·}_{·}_{·}_{·}_{·}_{·}_{·}_ {·}_{·}_{·}_{·}_{·}_{·}_{·}_{·}_{·}_{· H ·}_{·}_{·}_ {·}_{·}_{·}_{·}_{·}_{·}_{·}_{·}_{·}_{·}_{·}_{·}_{· }_{·}_{·}_{·}_{·}_{·}_{·}_{·}_{·}_{·}_{·}_{. }\a Tianjin Pipe Co., Ltd., to expand in Shanghai and Tianjin Pipe sales market in east China. Wanli Wang steel company spokesman that the current in the Chinese market has not formed the Western market economy, marketing system, that is, sales of full-fledged service model established, so, a new Wanli Wang Tianjin Steel Tube Company's aim is to explore how to apply the marketing concept of the Dutch company Tianjin Pipe Group sales in the company's products. Tianjin Steel Steel is also the glorious mountains and Malaysian Global Steel Corporation cooperation,[link widoczny dla zalogowanych], set up a specialized production stainless steel pipe and fittings, a joint venture - Tianjin Pipe Stainless Steel Hill. The joint venture's products 12.7 ~ 203.2mm diameter of 304,304 L,[link widoczny dla zalogowanych], 316 and 316L stainless steel welding,[link widoczny dla zalogowanych], etc. tube and stainless steel fittings, including the 45. and 90. long radius elbow, equal channel / level tee, concentric reducer fittings, eccentric reducers joints, can also produce the closures diameter of 12.7 ~ 203.2mm. The company's products are mainly used in oil and gas, petrochemical, pharmaceutical, brewing and automotive industries, in addition to products for the domestic market but also export the United States, Australia, India, Middle East,[link widoczny dla zalogowanych], Southeast Asia and East Asia and other countries and regions. Satellite feed companies in Germany SZFG roughness control the implementation of hot galvanized steel sheet in Germany's galvanized sheet SZFG volume of galvanized sheet production line can produce a high surface roughness requirements. The daily output of 45,000 tons production line hot dip galvanized coils, online control of surface roughness using two techniques. First, use of light machine has a so-called Pretex roll surface structure, surface covered with micro-level roll evenly spherical bulge, so that the whole strip of light generated when the 1.2 ~ 1.8m uniform roughness, the purpose is to strip deep drawing operation, lubricate the surface of the film to keep the same time conducive to corrosion. The second is galvanizing a new production line installed in the rear of roughness measuring instrument,[link widoczny dla zalogowanych], for online measurement of closed loop control. roughness of the strip line by continuous testing, continuous input data from a variety of strip rolling parameters established parameters and roughness control model, the use of PLC-line adjustment of parameters such as rolling force, to change the strip surface roughness to achieve surface roughness of the closed-loop control. One of the key equipment of new roughness measuring instrument series monochrome laser beam in the steel surface of the 5 ~ 7m of the spot, by reflection to the receiver unit can calculate the strip surface after the bump parameters The measuring instrument can simultaneously within the 8s 5m size on the metal surface area of millions of scanning, computed in a continuous strip test average surface roughness Ra and the peak value and draw the roughness of concave and convex curves. auspicious Quoted (MPTInternational} 2006, (6)
