I-China ithengisa ngokuqondile ikhoyili yensimbi egoqiwe ebandayo DC01-DC06 imiqulu yensimbi enamandla amakhulu
incazelo
Ikhoyili egoqiwe ebandayo isho umucu wensimbi ogoqwa ube ugqinsi oluthile ngokuqondile ngerola ekamelweni lokushisa bese igoqwa kuyo yonke ikhoyili yikhoyili. Uma kuqhathaniswa nekhoyili egoqiwe eshisayo, ikhoyili egoqiwe ebandayo iyakhanya, isiphetho esiphezulu, kodwa izoveza ukucindezelwa kwangaphakathi okwengeziwe, ngemva kokuginqika okubandayo ngokuvamile kudinga ukwelashwa okugoqiwe.
Ikhoyili yensimbi egoqiwe eshisayo isetshenziswa njengezinto ezingavuthiwe, emva kokukhetha i-asidi ukususa isikali se-oxide, ukugoqa okubandayo, ukugingqika kube ikhoyili eqinile. Amandla, ubulukhuni, ukuqina kanye ne-plasticity index of rolling hard rolls ithuthukiswa ukuqina komsebenzi obandayo okubangelwa ukuguquguquka okubandayo okuqhubekayo. , ngakho-ke ukusebenza kwesitembu kuzoba mpofu, kungasetshenziswa kuphela ukuguqulwa okulula kwezingxenye. Amakhoyili agoqeke kanzima angasetshenziswa njengezinto ezingavuthiwe ezitshalweni ezifaka amadiphu ashisayo ngoba imigqa yokufaka i-hot-dip galvanizing ifakelwe izintambo ze-deignition. Isisindo semiqulu eqinile egoqiwe ngokuvamile singamathani angama-20-40. Ama-pickling rolls ashisayo asongwa ngokuqhubekayo ekamelweni lokushisa. Ububanzi bangaphakathi bungama-610mm.
Izici zomkhiqizo
Ngenxa yokungabikho kokwelashwa kwe-annealing, ubulukhuni obuphezulu (HRB> 90), ukungakwazi ukusebenza kahle, kungenziwa kuphela ngaphansi kwama-degree angama-90 wokugoba okuqondile okuqondile (okuncike ekuqondeni kokugoqa).
Ukukubeka kalula, ukugoqa okubandayo kuyacutshungulwa futhi kugoqwe ngesisekelo sekhoyili egoqiwe eshisayo. Ngokuvamile, i-hot rolling - pickling - inqubo ebandayo yokugoqa.
Ishidi eligoqiwe elibandayo licutshungulwa kusuka eshidini eligoqiwe elishisayo ekamelweni lokushisa. Nakuba izinga lokushisa lensimbi lizokhuphuka ngesikhathi sokucubungula, lisabizwa ngokuthi ukugoqa okubandayo. Ngenxa yokuguquka okubandayo okuqhubekayo kokuginqika okushisayo, izakhiwo zemishini zimbi futhi ubulukhuni buphezulu kakhulu. Kumele ihunyushwe ukuze kubuyiselwe izinto zayo ezisebenza ngomshini, kanti lezo ezingenawo ama-anneal zibizwa ngokuthi amakhoyili asongwe kanzima. Amakhoyili asongwe kanzima ngokuvamile asetshenziselwa ukwenza imikhiqizo engadingi ukugotshwa noma ukwelulwa. Amakhoyili anogqinsi olungaphansi kuka-1.0 agoqwa nhlangothi zombili noma izinhlangothi ezine, ngenhlanhla.
Isicelo
Cold rolled strip isetshenziswa kabanzi ekukhiqizeni izimoto, imikhiqizo kagesi, isitokwe rolling, zezindiza, ukunemba amathuluzi, ukudla okusemathinini, njll Cold ipuleti iphuma isifinyezo esivamile carbon kwesakhiwo steel abandayo ipuleti iphuma, eyaziwa nangokuthi ipuleti eligoqiwe abandayo, ngokuvamile eyaziwa ngokuthi abandayo iphuma ipuleti, ngezinye izikhathi ngephutha ibhalwe ipuleti rolled. Ipuleti elibandayo liwumugqa oshisayo ogoqiwe wensimbi evamile ye-carbon structural, ephinde ibande igoqelwe ibe amapuleti ensimbi anogqinsi olungaphansi kuka-4mm. Ngenxa yezinga lokushisa elivamile, akukho isikali se-oxide, ngakho izinga eliphezulu lepuleti elibandayo lihle, ukunemba okuphezulu kwe-dimensional, okuhambisana nokwelashwa kwe-annealing, izakhiwo zayo zemishini kanye nokusebenza kwenqubo kungcono kunepuleti lensimbi eligoqiwe elishisayo, emikhakheni eminingi, ikakhulukazi emkhakheni wokukhiqiza izinto zikagesi zasendlini, kancane kancane ithathe indawo ye-hot rolling steel plate.
