步骤三、通过下料机1末端位置安装的工业相机2对切断管坯的切口位置进行实时拍摄录像，通过远程监控终端对下料段进行质检；
步骤四、通过启动修磨机4将下料完成的管坯原料进行表面和切断口边缘进行自动打磨修整；
步骤五、修磨完成的管坯件通过输送设备导入到第一加热炉3中进行分段加热管坯，并且分段加热分为预热段、加热段和保温段；
步骤六、将完成加热到指定温度的管坯导出，并且通过穿孔机5进行穿孔加工，通过设采用三辊式结构的穿孔机5保证管坯内壁的完整性；
步骤七、将完成穿孔的钛合金管材再送入到第二加热炉6的内部进行再加热，第二加热炉6设定内部的温度为945℃-1150℃；

步骤九、将管材沿着校直机8的输入端导入，并且通过校直机8对管材的弯曲部位进行调直；
步骤十、采用测径仪9对校直后的钛合金热轧无缝管内壁直径和外壁直径进行测量，通过连续测量管壁的内外径，从而计算出管壁各个位置的厚度；
步骤十一、将管材检测完成沿着传输辊道送入到抛丸机10中进行表面处理，所述抛丸机10通过高效抛丸器抛出的钢丸对外管壁进行处理，从而击碎钢管表面上的氧化皮、锈层及其他杂物，使之获得精细的光亮表面，提高工件的抗拉和抗压强度，为内表面涂漆保护增加附着力；

步骤十四、将管材输送到切割机13上，根据生产需要的长度对管材进行定量长度切断；
步骤十五、将切断后的管材送入到酸洗池14内进行酸洗化学处理，酸洗池14将管材作为电极，并且向酸洗池14内部通入电流进行酸洗操作，从而电流提高酸洗的质量和酸洗的速度；
步骤十六、将生产完成的钛合金热轧无缝管进行干燥处理，并且通过吊运设备将管材存放在库房15的指定整理架上进行存放。
综上所述，将采购的钛合金管坯材料进行检查，通过下料机1对钛合金管坯进行下料加工，通过修磨机4将下料完成的管坯原料进行表面和切断口边缘进行自动打磨修整，在经过第一加热炉3的加热后对管坯进行穿孔，穿孔完之后通过再加热并通过张力减径机7进行调整，之后通过校直处理和直径检测进行管材尺寸进行处理，通过管材抛丸进行表面处理，处理后通过对管内检测和管外检测来确保管材质量，随后根据生产需要的长度对管材进行定量长度切断，并将切断后的管材进行酸洗化学处理，最后，将生产完成的钛合金热轧无缝管进行干燥处理和打包入库处理，本说明中未作详细描述的内容属于本领域专业技术人员公知的现有技术。
