Mphamvu ndi Kulimba
Maraging 250 imaphatikiza mphamvu yokalamba kwambiri komanso kulimba bwino kuposa Maraging 300 yamphamvu kwambiri ndi Maraging 350 yamagetsi. Matrix yake ya kaboni yochepa imathandiza kuchepetsa kupangika kwa carbide yofooka komanso imathandizira zinthu zothandiza zopingasa komanso kukana kufalikira kwa ming'alu.
Kutha kugwira ntchito
Kutha kugwira ntchito bwino nthawi zambiri kumakhala bwino ngati chitsulo chopangidwa ndi aloyi chili ndi mphamvu zambiri. Ntchito zazikulu zotembenuza, kuboola, kugaya ndi kulumikiza ulusi nthawi zambiri zimamalizidwa zisanakhwime. Kuyika zida za carbide, makina olimba, chakudya chokhazikika komanso choziziritsira bwino ndizomwe zimalimbikitsidwa.
Kutha kupotoka
Maraging 250 ili ndi kuthekera kotha kusungunula chifukwa cha mpweya wochepa kwambiri. Kuyenerera kwa njira yosokera, njira yofananira ndi zodzaza, ukhondo ndi kukalamba pambuyo pa kusokera ziyenera kusankhidwa malinga ndi kapangidwe ka zigawo ndi zofunikira pa kayendetsedwe ka ndege kapena uinjiniya.
Kutentha Chithandizo
Chitsulochi chimapangidwa kuti chizimitse mvula. Nthawi zambiri chimaphikidwa ndi yankho, chimaziziritsidwa ndi mpweya, chimapangidwa pafupi ndi miyeso yomaliza kenako chimasungidwa pafupifupi 480°C. Kukalamba kumabweretsa mvula yapakati pa zitsulo zomwe zimakhala ndi kusintha kochepa poyerekeza ndi zitsulo zachikhalidwe zozimitsira moto.
Kudzimbiritsa ndi Chitetezo cha Pamwamba
Maraging 250 si chitsulo chosapanga dzimbiri ndipo siyenera kusankhidwa makamaka kuti isawonongeke ndi dzimbiri. Zophimba zoteteza, zokutira, zopaka mafuta kapena zosungira zoyendetsedwa bwino zingafunike m'malo ozizira, m'nyanja kapena m'malo odzaza ndi mankhwala.
N’chifukwa Chiyani Muyenera Kusankha SAKY STEEL?
M'mimba mwake, kutalika, njira yogwiritsira ntchito makina ndi momwe pamwamba pake pali zinthu zitha kuperekedwa malinga ndi zojambulazo.
Kuzindikiritsa zinthu kungasungidwe kuchokera ku zolemba za mphero mpaka kulongedza komaliza.
MTC (Mill Test Certificate / 质保书) ndi EN 10204 3.1 zitha kuperekedwa malinga ndi dongosolo.
Kuyesa kwa PMI, kuuma, kukoka, kukula ndi ultrasound kungakonzedwe ngati kwatchulidwa.
Kudula, kupukuta, kupotoza ndi kupukuta macheka kulipo malinga ndi kukula ndi kulekerera.
Mapaketi otetezedwa, mabokosi amatabwa, ma pallet ndi zizindikiro zotumizira zomwe zasinthidwa zikupezeka.

Kodi kuyezetsa kwa ultrasound kulipo?
UT ikhoza kukonzedwa kuti ipange mipiringidzo yoyenera ndi mipiringidzo yopangidwa ngati yatchulidwa. Funsoli liyenera kufotokoza njira yowunikira, mulingo wovomerezeka ndi zofunikira pakupereka malipoti.
Kodi SAKY STEEL ingapereke MTC?
Inde. MTC, kutsata kwa nambala ya kutentha ndi EN 10204 3.1 zikalata zitha kuperekedwa malinga ndi dongosolo logulira. Malipoti ena olimba, omangika, ozungulira, a PMI kapena a UT angakonzedwenso.
