The delayed fracture behaviors of CrMo-type high strength steels containing different amount of titanium(0to 0.10%)were *** steels were quenched at 880℃ and tempered from 400℃ to 650℃,and a wide range of tensile strength was *** sustained load tensile test was carried out by using notched tensile specimens in Walpole *** experimental results showed that with higher strength,the Ti-microalloyed steels show higher resistance to delayed fracture compared with non-microalloyed steel due to titanium beneficial role and microstructure *** undissolved TiC is uniformly distributed as strong hydrogen traps,retarding or preventing the diffusion and accumulation of hydrogen to lower-interaction energy sites,such as prior austenite and martensite lath boundaries in stress concentration ***,the grain refining effect of titanium is also an important factor to improve the delayed fracture resistance of Ti-microalloyed *** characteristics of delayed fracture remain nearly the same with titanium addition.

The netlike eutectic carbide in twin roll casting strip of W9Cr4V2 was dissolved and broken up gradually with increasing heating temperature during annealing treatment. Almost all eutectic carbides exist in granular form with heating temperature up to 950 ℃. It is considered that the refining of lamellar spacing made it possible for eutectic carbide to be granulated.

Highlights of Recent Advances in Refractories for Iron and Steel Industry in China

引用

China's Refractories 2003年第2期12卷 9-17页

作者： LITingshou ZHOUNingsheng SUTiansen ChinaIronandSteelAssociation Beijing100711China LuoyangInstituteofRefractoriesResearch LuoyangHenan471039China chinesesocietyformetals Beijing100711China

Recently procured outstanding achievements in iron and steel industry in China are presented by data or facts in steel output, energy consumption, technical and economical indicators and advanced technologies that are being adopted. The latest achievements in refractonries for this biggest user industry are reviewed, covering new refractories for CDQ coke oven, BF hearth, AOD Lining, long life tundish, SEN for clean steel making and regenerative reheating furnace . The reciprocal relationship is obvious that the rapid development of iron and steel industry has given an impetus to the advance of refractories industry, which in return has contributed greatly to the former.
