Zipangizo ziwiri, njira ziwiri — zonse zokonzeka kufufuzidwa.
Mapaipi ndi zolumikizira za ductile (EN 545 / EN 598)kukhala ndi moyo kapena kufa chifukwa cha kusungunuka, kotero timalamulira kuchokera ku gwero: Chitsulo cha nkhumba cha Q10/Q12 ndi waya wozungulira wozungulira zimalekanitsidwa pabwalo, gulu lililonse limafanana ndi satifiketi ya mphero (S ≤ 0.05%, P ≤ 0.08%). Malo obwera amawunikidwanso; zitsanzo zosungidwa zimayesedwanso pamalopo pogwiritsa ntchito kusanthula kwa metallographic.
Kutulutsa madzi achitsulo choyera (EN 877, ASTM A888)imayesedwa malinga ndi momwe makina amagwirira ntchito — mphamvu yokoka ndi kuuma kwa Brinell. Mapaipi ogulidwa amabwera ndi zitsanzo zofanana (spectrographic, metallographic, hardness, tensile) komanso satifiketi, zotsimikiziridwanso zikafika; zimalemba nthawi. Labotale yathu imawonetsanso mapaipi ndi zolumikizira mwachisawawa, ndikulemba momwe ntchito iliyonse imayendera ndi zithunzi ndi makanema.
Malo osungiramo zinthu zakale amodzi, zipata ziwiri: mankhwala asanasungunuke, magwiridwe antchito pambuyo pa oponya. Zolemba zimalankhula.
Pemphani gulu la QCLembani fayilo ndi RFQ yanu — tsimikizirani musanapereke.
