不锈钢无缝钢管是一种具有中空截面、周边没有接缝的长条钢材,是耐空气、蒸汽、水等弱腐蚀介质和酸、碱、盐等化学浸蚀性介质腐蚀的钢管又称不锈耐酸钢管,下面小编就给大家介绍一下它的制造工艺:
1.热轧(挤压无缝钢管):圆管坯→加热→穿孔→三辊斜轧、连轧或挤压→脱管→定径(或减径)→冷却→矫直→水压试验(或探伤)→标记→入库
轧制无缝管的原料是圆管坯,圆管胚要经过切割机的切割加工成长度约为1米的坯料,并经传送带送到熔炉内加热。钢坯被送入熔炉内加热,温度大约为1200摄氏度。燃料为氢气或乙炔,炉内温度控制是关键性的问题,圆管坯出炉后要经过压力穿孔机进行穿空。一般较常见的穿孔机是锥形辊穿孔机,这种穿孔机生产效率高,产品质量好,穿孔扩径量大,可穿多种钢种。穿孔后圆管坯就先后被三辊斜轧、连轧或挤压。挤压后要脱管定径,定径机通过锥形钻头高速旋转入钢胚打孔,形成钢管。钢管内径由定径机钻头的外径长度来确定,钢管经定径后,进入冷却塔中,通过喷水冷却,钢管经冷却后,就要被矫直。钢管经矫直后由传送带送至金属探伤机(或水压实验)进行内部探伤。若钢管内部有裂纹,气泡等问题,将被探测出,钢管质检后还要通过严格的手工挑选。钢管质检后,用油漆喷上编号、规格、生产批号等。并由吊车吊入仓库中。
2.冷拔(轧)无缝钢管:圆管坯→加热→穿孔→打头→退火→酸洗→涂油(镀铜)→多道次冷拔(冷轧)→坯管→热处理→矫直→水压试验(探伤)→标记→入库
冷拔(轧)无缝钢管的轧制方法较热轧(挤压无缝钢管)复杂。它们的生产工艺流程前三步基本相同。不同之处从第四个步骤开始,圆管坯经打空后,要打头,退火,退火后要用专门的酸性液体进行酸洗,酸洗后涂油,然后紧接着是经过多道次冷拔(冷轧)再坯管,专门的热处理,热处理后就要被矫直。
不锈钢无缝管是一种中空的长条圆形钢材,广泛用于石油、化工、医疗、食品、轻工、机械仪表等工业输送管道以及机械结构部件等。
