Tensile test - Siv ib qho piv txwv los ntawm txhua pawg ntawm tsis pub ntau tshaj 50 steel kav rau kev sim tensile. Siv cov qauv los ntawm txhua pawg ntawm ntau tshaj 50 steel kav rau ob qhov kev sim tensile.

Flattening test - Siv cov yeeb nkab ua tiav los ntawm txhua pawg, tab sis tsis yog ib qho uas siv rau kev nthuav dav, thiab coj ib qho qauv ntawm txhua qhov kawg rau kev sim flattening. Rau Qib C steel kav nrog lub cheeb sab nraud sib npaug los yog tsawg dua 2.375 ntiv tes, kua muag lossis tawg ntawm 12 thiab 6 cov ntsiab lus tsis yog lub hauv paus rau kev khawb.

Expansion test-Siv cov yeeb nkab ua tiav los ntawm txhua lub batch, tab sis tsis yog ib qho siv rau kev sib tw flattening, thiab coj cov qauv ntawm txhua qhov kawg rau kev nthuav dav.
Hardness test-Nqa ob lub kav hlau los ntawm txhua pawg rau Brinell lossis Rockwell hardness test.
Hydraulic test los yog kev sim tsis ua kom puas-Txhua cov yeeb nkab steel yuav tsum tau sim hydraulically. Kev kuaj tsis muaj kev puas tsuaj tuaj yeem siv los ntawm kev sim hydraulic raws li tus neeg yuav khoom lub npe.

Kev ua haujlwm
Tom qab cov yeeb nkab steel tau muab tso rau hauv lub boiler, nws yuav tsum muaj peev xwm tiv taus kev nthuav dav thiab kev ua haujlwm crimping yam tsis muaj kev tawg lossis tawg. Superheater steel kav yuav tsum muaj peev xwm tiv taus qhov tsim nyog forging thaum lub sij hawm tsim khoom nyob rau hauv ib txwm ua haujlwm, thiab tsis muaj qhov tsis xws luag yuav tshwm sim ntawm qhov vuam thiab khoov qhov chaw.
Lub cim tseem yuav suav nrog seb nws puas yog lub raj kub txheej txheem lossis lub raj ua kom txias.
