STKM11A STKM14B chubu chachitsulo chagalimoto
Kufotokozera
STKM11A ndi kalasi yachitsulo ya mapaipi achitsulo omwe amagwiritsidwa ntchito popanga makina, opangidwa kuchokera ku JIS G3445 wamba, ndipo ndi kalasi yaku Japan.STKM11A chitsulo chitoliro kalasi kalasi, zinthu zofanana SPHC, σ B ≥ 290MPa;Chitsulo cha kaboni chazinthu zamakina a STKM;
Chizindikiro cha SPHC poyambirira chinali cha ku Germany ndipo chidagwiritsidwanso ntchito ku Japan.Pambuyo pake, idayambitsidwa ndi mphero zoweta zachitsulo za Baosteel, zomwe zimayimira mbale zachitsulo zotentha (zomwe zimagwirizana ndi SPCC), zofanana ndi mbale zotentha za 10 # ndi 15 # zitsulo mumtundu wa GB699 (National Standard for High Quality). Carbon Structural Steel), yokhala ndi mpweya wambiri wa 0.1% -0.15%
Chithandizo cha Pamwamba:
1. Wakuda
2.Black Painted (chophimba cha varnish)
3.Magalati
4.Kupaka mafuta
5.Malinga ndi makasitomala.
JIS STKM11A ~ 18C/DIN ST52/ASTM A106, mwatsatanetsatane komanso mwankhalwe pamwamba pa mipope yachitsulo yokokedwa kuzizira yokhala ndi mainchesi amkati ndi akunja ndi apamwamba kuposa mapaipi ogudubuza otentha.Mafotokozedwewo amatha kusinthidwa kuti akwaniritse zofunikira zamphamvu zamakomedwe, mphamvu zokolola, elongation, etc;Mapaipi ozizira okokedwa bwino achitsulo okhala ndi ma diameter amkati ndi akunja angagwiritsidwe ntchito pamasilinda a pneumatic;Silinda yamafuta amafuta;Kugwedezeka kwa njinga yamoto ndi njinga;Air conditioner condenser;Foloko yakutsogolo ya Locomotive ndi foloko yakumbuyo;Mkono wamakina;Mafilimu obwezeretsanso granular;Chitoliro chotulutsa mpweya;Makina odzaza botolo;Makina odzaza;Jack;Mlimi;Wodzigudubuza kwa makina osindikizira, etc.
Machubu a JIS G3445 Precision zitsulo amagwiritsidwa ntchito makamaka pamagalimoto ndi makina olondola pamagalimoto ndi silinda.kugwiritsa ntchito kuthamanga, komanso kunyamula nthunzi, madzi, mizere yamapaipi a gasi.
