Description
本发明涉及一种在组合生产线上生产铜或铜合金焊接管材的生产方法,组合生产线由坯材浇铸设备、热轧机、管材成形和焊接设备以及焊接管材拉拔设备所组成。
铜管和铜合金管可以分为无缝管和焊接管。
无缝管例如通过实心管浇铸、带式压力挤管、皮格尔式冷轧和拉拔这样的生产过程来制造,在此也可以放弃皮格尔式冷轧。同样为人们熟知的方法是,用斜辊穿轧法对实心管穿孔、皮格尔式冷轧并接着拉拔成成品尺寸。还要提及的方法是,在这种方法中先浇铸空心管,然后在皮格尔式冷轧后将其拉拔。所有上述方法都存在着在带式压力挤管中所出现的高额制造费用、在空心管浇铸中管材质量不好这样的缺点。此外无缝管存在较大的壁厚误差。
焊接管通常由带式浇铸板坯加工而成,板坯在平板热轧机上预轧,接着进行冷轧、切断和焊接。紧接着在焊接之后按照通常的拉拔方法进行拉拔。焊接管方法中的缺点是高额带材制造费用,这使得管材的生产是不经济的。
带材制造可以按照不同的方法进行。通常是板坯的带式浇铸、板坯的热轧、表面铣削并接着冷轧、将冷轧带材拆卷并接着切断成条带、然后对条带进行继续加工。这样制造的冷轧带材的优点在于,在良好的表面质量情况下可以实现高于100,000吨/年的高生产能力。缺点在于间断地生产过程和高额制造费用。
另一种方法建议,浇铸薄板坯,薄板坯可以省去宽带材的热轧。在这里也接着要进行带材表面铣削,然后进行带材冷轧、卷绕并切断成条带。这种方法可以连续进行,在良好的表面质量情况下可以实现低于100,000吨/年的中等生产能力。这种方法的缺点也是制造费用过高。
第三种方法以所谓的高度简化方法为公众所知。在此带材在石墨铸型中以v=1m/min的浇铸速度被浇铸、表面铣削、带材以大量减少轧制道次地被冷轧、卷绕并切断成条带。这种方法可以连续运转,表面质量良好。这种方法的缺点是在高制造费用情况下只有大约10,000吨/年的低生产能力。
本发明的目的在于,实现以改善的方法制造廉价的铜或铜合金管材,这种管材具有更高的尺寸精确度和表面质量,在这种方法中轧制带材被加工成纵向焊缝焊接管材。此外力争实现较小至较大(10,000至100,000吨/年之间)生产能力的经济性。
按照本发明的方法步骤在权利要求1中的特征部分通过方法步骤a至j的顺序所描述。可以证实,当初始带材以给定尺寸范围和预定浇铸速度浇铸时可以实现按尺寸加工式(massgeschneidertes)的条带生产,以省去预轧板坯的纵向切断。这种条带在低制造费用情况下具有良好的表面质量和有利的材料性能。
按照本发明的特殊特征,初始带材的浇铸可以在带材浇铸设备上或者在浇铸轮上实现。这两种浇铸方法由于具有很快的浇铸速度而与众不同,并因此特别适合于以相应尺寸直接继续加工的条带的经济性生产,在此铸轮目前只在线材制造中使用。
当按照本发明的另一建议,初始带材的热轧在600至900℃之间进行时,本方法可以实现材料晶体颗粒为30-40μm的生产,这种晶体颗粒在冷轧后为带材成形为焊接管材时提供更好的条件。
按照本发明中间带材的倒棱边直接在焊接设备上进行,由此除了省去带材纵向切断以外还省去了预先倒棱边。
热轧初始带材的去氧化皮可以在生产线上按照惯用的去氧化皮方法,例如通过化学酸洗方法来实现。
按照本发明的另一特征,用于纵向焊缝的有利方法是采用公知的高频钨极惰性气体保护焊接方法或激光焊接方法,该方法包括下列步骤:拆卷、中间带材的矫正和对焊、成形、焊接、内外去毛刺(如果高频焊接的话)、精整、切断、打捆和排出内部碎屑。
按照本发明,纵向焊缝管材的拉拔可以采用公知的拉拔方法,该方法包括下列步骤:拆捆、滚筒式拉拔或连续直线拉拔、必要时的中间退火(当品质等级为软和半硬的时候)、精拉拔和必要时的软化退火(例如对于热交换管材)。
按照本发明的方法步骤,如在权利要求9的特征部分所给定的,也可以考虑这种选择,生产内部加筋的纵向焊缝管材,而且同样经济地在连续或部分连续地生产过程中保证具有良好的表面质量。
按照本发明的方法是具有优点的,因为制造焊接铜管材或焊接铜合金管材在连续方法过程中从较低直至较高(10,000直至100,000吨/年)的生产能力都是经济的,对于内部加筋的管材甚至可以低于1000吨/年或更低仍然是经济的。连续的方法步骤在采用高速焊接设备的情况下一方面可以实现极高的生产能力,而另一方面不会对管材质量产生消极影响。尽管省去现有技术状况所存在的带材表面铣削,浇铸带材表面仍然能适应于管材制造中精密冷轧带材的条件。在热轧过程中所建立的30至40μm的晶体颗粒对于带材成形为焊接管材能够比到目前为止的对于软化(退火)材料所能实现的条件提供更为有利的前提。按照本发明的方法已经首次成功地应用于制造有色金属焊接管材方法,由于这种方法的高生产能力、柔韧性和低费用而使其没有现有技术现状所存在的缺陷。
