L0--試樣原始標距長度，mm。斷面收縮率：(ψ)在拉伸試驗中，試樣拉斷后其縮徑處橫截面積的縮減量與原始橫截面積的百分比，稱為斷面收縮率。以ψ表示，單位為%。式中：S0--試樣原始橫截面積，mm2; S1--試樣拉斷后縮徑處的少橫截面積，mm2。硬度指標：金屬材料抵抗硬的物體壓陷表面的能力，稱為硬度。根據(jù)試驗方法和適用范圍不同，硬度又可分為布氏硬度、洛氏硬度、維氏硬度、肖氏硬度、顯微硬度和高溫硬度等。對于管材一般常用的有布氏、洛氏、維氏硬度三種。布氏硬度(HB)：用一定直徑的鋼球或硬質合金球，以規(guī)定的試驗力(F)壓入式樣表面，經(jīng)規(guī)定保持時間后卸除試驗力，測量試樣表面的壓痕直徑(L)。布氏硬度值是以試驗力除以壓痕球形表面積所得的商。以HBS(鋼球)表示，單位為N/mm2(MPa)。</div><p><img

當輸入熱量不足時，被加熱的精密鋼管邊緣達不到精密鋼管溫度，金屬組織仍然保持固態(tài)，形成未熔合或未焊透;當輸入熱時不足時，被加熱的精密鋼管邊緣超過精密鋼管溫度，產(chǎn)生過燒或熔滴，使精密鋼管形成熔洞。精密鋼管的兩個邊緣加熱到精密鋼管溫度后，在擠壓輥的擠壓下，形成共同的金屬晶?；ハ酀B透、結晶，終形成牢固的精密鋼管。若擠壓力過小，形成共同晶體的數(shù)量就小，精密鋼管金屬強度下降，受力后會產(chǎn)生開裂;如果擠壓力過大，將會使熔融狀態(tài)的金屬被擠出精密鋼管，不但降低了精密鋼管強度，而且會產(chǎn)生大量的內外毛刺，甚至造成精密鋼管搭縫等缺陷。第三，精密鋼管應盡量接近擠壓輥位置。若感應圈距擠壓輥較遠時，有效加熱時間較長，熱影響區(qū)較寬，精密鋼管強度下降;反之，精密鋼管邊緣加熱不足，擠壓后成型不良。

提高冷軋精密無縫鋼管機產(chǎn)量的第三個途徑是，必須提高軋管機的有效工作系數(shù)，值。要提高9，將涉及多方面的問題.一方面，要求軋管機的設計要合理，加工制造精度高，以減少維護及檢修停機時間。另一方面要提高軋管的機械化、‘自動化水平，以減少輔助操作時間。第三方面，也是很重要的發(fā)展方向，要實現(xiàn)冷軋管機不停機，連續(xù)裝科和連續(xù)軋制.提高軋管機產(chǎn)量的第四個措施是增加同時軋制管材的根數(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‘對于中間工序，是完全可以的?，F(xiàn)在的精密鋼管能夠被廣泛投入到流體管道中使用，其內壁光滑，同時也具有一定的抗腐蝕性，在安裝的過程中也具有一定的優(yōu)勢，在安裝的過程中只需要焊接機可，可以省去檢查其氣密性的步驟，同時也可以減少對精密鋼管護理的不必要開支。
