泸州古蔺大鼎金属材料有限公司拥有一支经验丰富、技术创新的专业【无缝钢管】研发团队。优质创新、诚信合作、互惠互利、共同发展是泸州古蔺大鼎金属材料有限公司持续发展的永恒目标。



公司拥有大中型冷拔精密无缝钢管和冷轧精密无缝钢管轧机六条生产线,一个辊底热处理炉和三套普通冷拔无缝钢管轧机。先进的生产检测设备是制造高质量精密无缝钢管的必要保证,因此公司高度重视生产设备的现代化,确保行业领先水平。采用国外先进技术制造的无缝冷轧生产设备精度高、生产规格和型号广,比一般自动冷轧机更先进。同时配备先进的自动控制系统和在线质量检测系统。确保产品质量的稳定性和可靠性。同时,我们还经营宝钢、天津无缝钢管、攀钢、包钢、衡阳华菱、山东墨龙、山东大鼎、凤宝、建龙、江阴长江、中国钢铁联盟、汇通等。
自3月份以来,国内无缝钢管的产量一直在放缓。中国2012年10月无缝钢管产量为248万#,比去年同期增长8.6%;1-10月无缝钢管累计产量达到22859万#,比去年同期增长6.9%。有河北、江苏、山东、河南、重庆等省(区、市)解决无缝钢管过剩产能,有河北、山西、内蒙古、辽宁、河南等省(区、市)解决煤炭过剩产能。



添加钛、铌等微合金元素形成弥散的氮化物或碳氮化物,导致冷轧精密光亮钢管的韧脆转变温度升高。(3)晶粒尺寸对韧脆转变温度有影响,随着晶粒粗化,韧脆转变温度升高。冷轧和精密光亮钢管的晶粒脆化倾向得到了广泛的应用。高春铁(0.01% C)的Tc在该温度以下的100C完全易碎。冷轧精密光亮钢管中大部分合金元素都提高了韧脆转变温度和冷脆倾向。室温以上发生韧性断裂时,冷轧精密光亮钢管的断口为韧窝断裂,低温脆性断裂时断口为解理断裂。
Following the decline in crude steel production in the first ten days of this month, crude steel production rose again in the first ten days of this month. Inventories of heat preservation and anticorrosion pipe manufacturers and factories also declined. The production situation of secondary or steel plants is not clear. At present, as raw material prices continue to fall, consumer enterprises still have profit margins; coupled with financial pressure, most steel mills need to maintain operation in order to continue to obtain savings; therefore, steel mills still adhere to a higher start-up rate; Anshan region, for example, as of this month, Tangshan blast high production capacity application rate. Up to.0%, the rate of increase was normal.


Precision steel pipes are mainly used to produce seamless or welded products such as pneumatic or hydraulic components, such as cylinders or cylinders, because of their advantages such as no oxide layer on the inner and outer walls, high pressure, no leakage, high precision and so on. SH, no cold bending deformation, flat and no crack. Precision steel pipe mainly produces 10, 20, 35, 45, 40 cr, 42CrMo grade precision seamless steel pipe can also be consulted and supplied.
At heating time (s) = KD, D is the thickness of the workpiece, mm, K as the coefficient, and the factory data. (3) cooling. Different cooling systems are used for different tissues. It is usually cooled in static air. If the workpiece is large, it can be cooled by blowing or fog. The length is usually也许正是因为这个原因,在过去相当长的时间,另一方面,虽然有关各方已提出了许多警告,产能过剩的钢铁行业,甚至进行产业结构调整,地方政府仍然回避了铁和ST通过“变为零”等政策的对策就是鳗鱼项目;同时,为了维护相关的钢铁产能对地方GDP的贡献,有些地方还不遗余力地支持当地落后产能项目日即使他们清楚地知道一些地方钢铁项目的产量明显落后,政策倾斜。
