1 .Intshayelelo emfutshane yombhobho wolwakhiwo

Umbhobho ongenamthungo wesakhiwo (i-GB / T8162-2008) isetyenziselwa isakhiwo esiqhelekileyo kunye nesakhiwo somatshini wombhobho ongenamthungo.I-tube yensimbi engenamthungo yahlulwe kwiindidi ezahlukeneyo zokusetyenziswa.

Umbhobho wensimbi engenamthungo wesakhiwo (i-GB / T14975-2002) ngumbhobho oshushu (i-extruded, eyandisiweyo) kunye ne-cold-drawn (eqengqelekayo) ipayipi engenamthungo eyenziwe ngensimbi engenasici esetyenziselwa imichiza, i-petroleum, i-textile, unyango, ukutya, oomatshini kunye namanye amashishini, iipayipi ezichasene ne-corrosion kunye nezakhiwo.

I-GB/T8162-2008 (umbhobho ongenamthungo wesakhiwo) isetyenziselwa ubukhulu becala kunye nesakhiwo soomatshini. Izinto ezimele ummeli (uphawu) : intsimbi ye-carbon 20, i-45 yensimbi, i-Q235, i-alloy steel Q345, i-20Cr, i-40Cr, i-20CrMo, i-30-35CrMo, i-45CrMo kunye ne-so.

Umbhobho wentsimbi ongenamthungo

Ngenxa yenkqubo yayo yokuvelisa yahlukile, yahlulahlulwe yaba ityhubhu yentsimbi eshushu eqengqelekayo (extruded) engenamthungo kunye nebandayo etsalwa (iqengqiwe) engenamthungo ityhubhu yentsimbi eluhlobo.

A.Amagqabantshintshi okuqukuqela kwenkqubo

Ukuqengqeleka okushushu (ityhubhu yentsimbi ekhutshiweyo engenamthungo) : iityhubhu engqukuva → ukufudumeza → ukugqobhoza → ukuqengqeleka okuqengqelekayo okuthathu, ukuqengqeleka okuqhubekayo okanye ukukhutshwa → ukuhluba ityhubhu → ukulinganisa (okanye ukunciphisa) → ukupholisa → ityhubhu engenanto → ukulungisa → uvavanyo loxinzelelo lwamanzi (okanye ukubonwa kwesiphene) → ukumakisha → ukugcinwa.

Umzobo obandayo (uqengqeleka) ityhubhu yentsimbi engenamthungo: ityhubhu engqukuva → ukufudumeza → ukugqobhoza → isihloko → ukuqhola → ukuchola → ukufakwa kweoli (icwecwe lobhedu) → umzobo obandayo ohamba ngeendlela ezininzi (ukuqengqeleka okubandayo) → ityhubhu engenanto → unyango lobushushu → ukulungisa → uvavanyo loxinzelelo lwamanzi (ukubona impazamo) → ukumakisha → ukugcinwa.
