Ukuqondisa
Ngemuva kokukhishwa kwe-annealing, izimpahla zidluliselwa ngomshini wokuqondisa ama-roller ayisikhombisa ukuze kuzuzwe ukuqondisa okufanele kwamashubhu.
Eddy okwamanje
Ngemuva kokuqondisa, ishubhu ngalinye lidluliswa emshinini wamanje we-eddy ukuze kutholwe ukuqhekeka kwendawo nokunye ukonakala.Amashubhu kuphela adlula i-eddy current afanele ukuthunyelwa kumakhasimende.
Ukuqeda
Ishubhu ngalinye ligcotshwe ngamafutha amelana nokugqwala noma lifakwe ivanishi ukuze livikeleke futhi limelane nokugqwala ngokwesidingo samakhasimende, isiphetho seshubhu ngalinye simbozwa ngamakepisi epulasitiki ukuze kugwenywe umonakalo osendleleni, ukumaka kanye nemininingwane iyafakwa futhi izimpahla zilungele ukuthunyelwa. .
I-Q355 Amapayipi ensimbi angenamthungo e-Hot Rolled Carbon asetshenziswa kakhulu emshinini wenuzi, ukuthutha igesi, i-petrochemical, i-shipbuilding kanye nezimboni zamabhayela, anezici zokumelana nokugqwala okuphezulu kuhlanganiswe nezakhiwo ezifanele zemishini.
