I-Q235 steel plate kanye ne-Q345 steel plate ngokuvamile azibonakali ngaphandle. Umehluko wombala awuhlobene nezinto zensimbi kodwa ubangelwa izindlela zokupholisa ezihlukene ngemva kokuba insimbi isikhiqizwe. Ngokuvamile, ubuso bubomvu ngemva kokupholisa kwemvelo. Uma kusetshenziswa ukupholisa okusheshayo, ungqimba oluminyene lwe-oxide lwakha phezulu, oluzovela lumnyama.
Ngomklamo wamandla ojwayelekile, i-Q345 isetshenziswa ngoba inamandla angaphezu kwe-Q235 yensimbi, yonga insimbi ngo-15% - 20% uma kuqhathaniswa ne-Q235. Ngomklamo wokulawula ukuzinza, i-Q235 ingcono. Umehluko wamanani ngu-3% - 8%.
Mayelana nokuhlonza, kunezitatimende eziningana:
A.
- Embonini, izindlela zokushisela zingasetshenziswa ukuhlukanisa phakathi kwezinto ezimbili. Isibonelo, insimbi encane eyindilinga ishiselwa ezingcezu ezimbili zensimbi kusetshenziswa induku yokushisela i-E43, bese kusetshenziswa amandla okugunda. Izinhlobo ezimbili zezinto zepuleti lensimbi zingahlukaniswa ngokusho kwesimo sokubhujiswa.
- Imboni ingasebenzisa isondo lokugaya ukuze ihlukanise phakathi kwezinto ezimbili. Uma ugaya insimbi ye-Q235 ngesondo lokugaya, izinhlansi ziyizinhlayiya eziyindilinga futhi zimnyama ngombala. Ngenkathi okwensimbi ye-Q345, izinhlansi zihlukene kabili futhi zigqamile ngombala.
- Ngokomehluko wombala we-shear surface yezinsimbi ezimbili, izinhlobo ezimbili zensimbi nazo zingahlukaniswa. Ngokuvamile, unqenqema lokugunda lwe-Q345 lumhlophe ngombala.
B.
- Ngokusho kombala we-steel plate, izinto ze-Q235 ne-Q345 zingahlukaniswa: umbala we-Q235 uluhlaza, futhi i-Q345 ibomvu ngandlela-thile (lokhu kuphela kwensimbi engena ensimini futhi ayikwazi ukuhlukaniswa ngokuhamba kwesikhathi).
- Ukuhlolwa kwezinto ezibonakalayo okuhlukaniseka kakhulu ukuhlaziya amakhemikhali. Okuqukethwe kwekhabhoni ye-Q235 ne-Q345 kuhlukile, futhi okuqukethwe kwamakhemikhali nakho kuhlukile. (Lena yindlela engenangqondo).
- Ukuhlukanisa phakathi kwezinto ze-Q235 ne-Q345 usebenzisa i-welding: faka izingcezu ezimbili zensimbi yezinto ezingaziwa futhi ushise ngenduku evamile yokushisela. Uma kukhona ukuqhekeka ohlangothini olulodwa lwepuleti lensimbi, kufakazelwa ukuthi yi-Q345 material. (Lokhu okuhlangenwe nakho okungokoqobo).
