將精(jing)(jing)(jing)(jing)(jing)軋(ya)(ya)(ya)管(guan)(guan)(guan)送入精(jing)(jing)(jing)(jing)(jing)軋(ya)(ya)(ya)管(guan)(guan)(guan)機組,經(jing)多(duo)道軋(ya)(ya)(ya)輥(gun)滾壓(ya)(ya),精(jing)(jing)(jing)(jing)(jing)軋(ya)(ya)(ya)管(guan)(guan)(guan)逐漸卷起,形成有開口(kou)(kou)間隙(xi)(xi)的圓形精(jing)(jing)(jing)(jing)(jing)軋(ya)(ya)(ya)管(guan)(guan)(guan),調整擠(ji)壓(ya)(ya)輥(gun)的壓(ya)(ya)下量,使(shi)精(jing)(jing)(jing)(jing)(jing)軋(ya)(ya)(ya)管(guan)(guan)(guan)間隙(xi)(xi)控制在1~3mm,并使(shi)焊(han)口(kou)(kou)兩端齊平。如間隙(xi)(xi)過(guo)大,則造成鄰(lin)近(jin)效應(ying)減(jian)少,渦流(liu)熱(re)量不足,精(jing)(jing)(jing)(jing)(jing)軋(ya)(ya)(ya)管(guan)(guan)(guan)晶(jing)間接合不良而產生未熔合或(huo)開裂。如間隙(xi)(xi)過(guo)小(xiao)則造成鄰(lin)近(jin)效應(ying)增(zeng)大,精(jing)(jing)(jing)(jing)(jing)軋(ya)(ya)(ya)管(guan)(guan)(guan)熱(re)量過(guo)大,造成精(jing)(jing)(jing)(jing)(jing)軋(ya)(ya)(ya)管(guan)(guan)(guan)燒損(sun);或(huo)者(zhe)精(jing)(jing)(jing)(jing)(jing)軋(ya)(ya)(ya)管(guan)(guan)(guan)經(jing)擠(ji)壓(ya)(ya)、滾壓(ya)(ya)后(hou)形成深(shen)坑(keng),影響精(jing)(jing)(jing)(jing)(jing)軋(ya)(ya)(ya)管(guan)(guan)(guan)表(biao)面質量。
精軋(ya)(ya)管(guan)溫度(du)主(zhu)(zhu)要(yao)受高頻(pin)(pin)(pin)渦(wo)(wo)流(liu)(liu)熱功率的(de)影響,根(gen)據(ju)公式可(ke)(ke)(ke)知(zhi)(zhi),高頻(pin)(pin)(pin)渦(wo)(wo)流(liu)(liu)熱功率主(zhu)(zhu)要(yao)受電(dian)(dian)(dian)流(liu)(liu)頻(pin)(pin)(pin)率的(de)影響,渦(wo)(wo)流(liu)(liu)熱功率與(yu)電(dian)(dian)(dian)流(liu)(liu)激(ji)(ji)勵(li)(li)頻(pin)(pin)(pin)率的(de)平方成(cheng)正比;而電(dian)(dian)(dian)流(liu)(liu)激(ji)(ji)勵(li)(li)頻(pin)(pin)(pin)率又受激(ji)(ji)勵(li)(li)電(dian)(dian)(dian)壓(ya)(ya)(ya)、電(dian)(dian)(dian)流(liu)(liu)和電(dian)(dian)(dian)容(rong)、電(dian)(dian)(dian)感(gan)(gan)的(de)影響。激(ji)(ji)勵(li)(li)頻(pin)(pin)(pin)率公式為(wei):f=1/[2π式中(zhong):f-激(ji)(ji)勵(li)(li)頻(pin)(pin)(pin)率;C-激(ji)(ji)勵(li)(li)回路中(zhong)的(de)電(dian)(dian)(dian)容(rong),電(dian)(dian)(dian)容(rong)=電(dian)(dian)(dian)量/電(dian)(dian)(dian)壓(ya)(ya)(ya);L-激(ji)(ji)勵(li)(li)回路中(zhong)的(de)電(dian)(dian)(dian)感(gan)(gan),電(dian)(dian)(dian)感(gan)(gan)=磁(ci)通量/電(dian)(dian)(dian)流(liu)(liu)上式可(ke)(ke)(ke)知(zhi)(zhi),激(ji)(ji)勵(li)(li)頻(pin)(pin)(pin)率與(yu)激(ji)(ji)勵(li)(li)回路中(zhong)的(de)電(dian)(dian)(dian)容(rong)、電(dian)(dian)(dian)感(gan)(gan)平方根(gen)成(cheng)反比、或者(zhe)與(yu)電(dian)(dian)(dian)壓(ya)(ya)(ya)、電(dian)(dian)(dian)流(liu)(liu)的(de)平方根(gen)成(cheng)正比,只要(yao)改(gai)變(bian)回路中(zhong)的(de)電(dian)(dian)(dian)容(rong)、電(dian)(dian)(dian)感(gan)(gan)或電(dian)(dian)(dian)壓(ya)(ya)(ya)、電(dian)(dian)(dian)流(liu)(liu)即可(ke)(ke)(ke)改(gai)變(bian)激(ji)(ji)勵(li)(li)頻(pin)(pin)(pin)率的(de)大小,從而達到(dao)控制精軋(ya)(ya)管(guan)溫度(du)的(de)目的(de)。對于低(di)碳鋼,精軋(ya)(ya)管(guan)溫度(du)控制在1250~1460℃,可(ke)(ke)(ke)滿足管(guan)壁厚3~5mm焊透要(yao)求。另外,精軋(ya)(ya)管(guan)溫度(du)亦(yi)可(ke)(ke)(ke)通過調節(jie)精軋(ya)(ya)管(guan)速(su)度(du)來實現。
