rolling weight
1.Utilizing adequate metallurgical means,welding prccess and cold -rolling plant matched with corresponding technclrgy. Coil weight can reach 600kg/ccil and 30kg/ccil respectively for 0.5 × 200mm and 0.5×24mm cold strips,while surface quality tolerance,burr,lateral flexure of strip approach and comes up to the level cf imported materials also,hardness may be adjusted in accordance with the requirement of users.
2.This article explores the factors affecting thickness fluctuation in medium and heavy plate,sums up the effective method of achieving high accuracy thickness control in actual production based on the production practice in rolling a batch of ship plate with delivered weight not greater than theoretical value using 2800mm mill by Anyang Steel Medium Plate Plant.
4.Through comparing the influence of two different kinds of hot-rolling processes on low carbon microalloyed steel, we concluded that fine M-A structure and precipitates could be gained by reducing the finish rolling and coiling temperatures, therefore the yield strength and toughness will be improved, especially the SA(Shear Area) percentage of DWTT(Drop Weight Tear Test).
6.The result showed that sea encumber polypeptide have no obvious effect on body weight in mice, significantly prolong the time of loaded-swimming and rolling stick, strongly degrade the content of blood area nitrogen and increase the content of hepatic glycogen of post exercise mice, The study indicates that sea cucumber polypeptide has significant anti-fatigue effect.
