Drill virga huwa tipikament magħmul ta ' grad għoli azzar dovut għal tiegħu speċifiku applikazzjoni rekwiżiti. Grad għoli azzar referenzi għal liga azzar li fih traċċa elementi bħal chrome (Cr) , tungstenu (W) , molibdenu (Mo) , u vanadju (V) li itejjeb tiegħu mekkaniku proprjetajiet.
Dawn gradi ta' azzar tipikament have a higher strength, ebusija, wear resistance, u korrużjoni reżistenza minn ordinarju karbonju azzar.
Drill rod is used for rock drilling and excavation engineering. It is required to have high wear resistance and fatigue resistance, good toughness and impact resistance, and can withstand high impact loads and fatigue loads. In addition, drill rod is also required to have good straightness and roundness, low surface roughness, and small size variance. Therefore, drill rod is typically made of high-grade alloy steel.
Grad għoli liga azzar għandu il li ġejjin karatteristiċi:
Għoli saħħa u ebusija: Dan jista ' itejjeb l- xedd reżistenza u għeja reżistenza ta' drill rod, u estensjoni its servizz ħajja.
Tajjeb ebusija u impatt reżistenza: Dan jista ' itejjeb il- abbiltà ta' drill virga biex tiflaħ impatt tagħbijiet u għeja tagħbijiet , u aċċidentali ksur matul skavar inġinerija.
Good straightness and roundness: This can ensure the accuracy of drilling and the smoothness of excavation engineering.
Baxx wiċċ ħruxija: Dan jista ' inaqqas l- xedd ta' il - drill bit / 2c jestendi is-servizz ħajja ta ' il drill bit, u ittejjeb l- effiċjenza ta ' skavar inġinerija.
Small size variance: This can ensure the interchangeability of drill rod and facilitate field replacement and maintenance.
Komuni gradi ta ' grad għoli liga azzar użat għal drill virga jinkludu 42CrMo, 35CrMo, 30CrMo, 27SiMn, eċċ., li jista ' jissodisfa l-aktar rekwiżiti għal skavar inġinerija. Il- manifattura proċess ta ' drill virga tipikament jinkludi forġa, sħana trattament, quenching u tempering, threading, eċċ., li jeħtieġ strett kwalità kontroll biex jiżgura il - mekkaniku proprjetajiet u dimensjonali eżattezza ta ' il-prodott .
Drill rod is typically made of high-grade alloy steel due to its specific mechanical properties requirements for excavation engineering. The grades of steel used for drill rod are selected according to different applications and working conditions, while the manufacturing process requires strict quality control to ensure the accuracy and reliability of the product.
