提高冷軋精密無(wú)縫鋼管機(jī)產(chǎn)量的第三個(gè)途徑是，必須提高軋管機(jī)的有效工作系數(shù)，值。要提高9，將涉及多方面的問(wèn)題.一方面，要求軋管機(jī)的設(shè)計(jì)要合理，加工制造精度高，以減少維護(hù)及檢修停機(jī)時(shí)間。另一方面要提高軋管的機(jī)械化、‘自動(dòng)化水平，以減少輔助操作時(shí)間。第三方面，也是很重要的發(fā)展方向，要實(shí)現(xiàn)冷軋管機(jī)不停機(jī)，連續(xù)裝科和連續(xù)軋制.提高軋管機(jī)產(chǎn)量的第四個(gè)措施是增加同時(shí)軋制管材的根數(shù)。需要指出的是，線數(shù)增加并不能使軋管機(jī)的產(chǎn)量成整數(shù)倍增加，而且成品管的精度將有所降低‘對(duì)于中間工序，是完全可以的。現(xiàn)在的精密鋼管能夠被廣泛投入到流體管道中使用，其內(nèi)壁光滑，同時(shí)也具有一定的抗腐蝕性，在安裝的過(guò)程中也具有一定的優(yōu)勢(shì)，在安裝的過(guò)程中只需要焊接機(jī)可，可以省去檢查其氣密性的步驟，同時(shí)也可以減少對(duì)精密鋼管護(hù)理的不必要開(kāi)支。

精密鋼管溫度主要受高頻渦流熱功率的影響，根據(jù)公式可知，高頻渦流熱功率主要受電流頻率的影響，渦流熱功率與電流激勵(lì)頻率的平方成正比;而電流激勵(lì)頻率又受激勵(lì)電壓、電流和電容、電感的影響。激勵(lì)頻率公式為：f=1/[2π式中：f-激勵(lì)頻率;C-激勵(lì)回路中的電容，電容=電量/電壓;L-激勵(lì)回路中的電感，電感=磁通量/電流上式可知，激勵(lì)頻率與激勵(lì)回路中的電容、電感平方根成反比、或者與電壓、電流的平方根成正比，只要改變回路中的電容、電感或電壓、電流即可改變激勵(lì)頻率的大小，從而達(dá)到控制精密鋼管溫度的目的。對(duì)于低碳鋼，精密鋼管溫度控制在1250~1460℃，可滿(mǎn)足管壁厚3~5mm焊透要求。另外，精密鋼管溫度亦可通過(guò)調(diào)節(jié)精密鋼管速度來(lái)實(shí)現(xiàn)。
