3. Ukuqengqeleka okubandayo:

Iikhoyili eziqengqeleke nzimaIikhoyili eziqengqelekayoAmaphepha enziwe ngombane we-GB yenkcenkceshe yetoti ye-WISCO yokusetyenziswa kwentsimbi yesilicon.

4. Ipleyiti yentsimbi ebilisayo kunye nepleyiti yentsimbi ebuleweyo:

1. Ukubilisa ipleyiti yentsimbi yintsimbi yentsimbi eshushu-isolwe kwintsimbi eqhelekileyo yekhabhoni yolwakhiwo lwentsimbi.Ukubilisa intsimbi luhlobo lwentsimbi ene-deoxidation engaphelelanga.Kuphela umlinganiselo othile we-deoxidizer ebuthathaka isetyenziselwa ukukhupha intsimbi etyhidiweyo.Isiqulatho seoksijini yentsimbi etyhidiweyo siphezulu.Xa isinyithi esinyibilikisiweyo sitofwa kungundo lwe-ingot, ikhabhoni kunye neoksijini ziyasabela ukuvelisa isixa esikhulu segesi, nto leyo ebangela ukuba intsimbi enyibilikisiweyo ibile., Intsimbi ebilayo yafumana igama layo kule nto.Insimbi ene-rimmed inomxholo ophantsi wekhabhoni, kwaye ngenxa yokuba ingasebenzisi i-ferrosilicon ye-deoxidation, umxholo we-silicon kwintsimbi nawo uphantsi (Si <0.07%).Umaleko wangaphandle wentsimbi ebilayo ukhazimliswa phantsi kweemeko zobundlobongela bentsimbi etyhidiweyo ebangelwa kubila, ngoko ke umaleko womphezulu ucocekile kwaye uxinene, unomgangatho olungileyo womphezulu, iplastikhi elungileyo kunye neempawu zesitampu, akukho mingxunya enkulu yokuncipha, kunye nokusika intloko. Izinga lokuvelisa i-rimmed steel lilula, ukusetyenziswa kwe-ferroalloy kuncinci, kwaye ixabiso lentsimbi liphantsi.Iipleyiti zentsimbi ezibilayo zisetyenziswa ngokubanzi ekwenzeni iindawo ezahlukeneyo zokutsibela, ulwakhiwo kunye nezakhiwo zobunjineli kunye nezinye ezingabalulekanga kangako kumatshini.Nangona kunjalo, kukho ukungcola okuninzi kumbindi wentsimbi ebilayo, ulwahlulo lunzulu, ulwakhiwo aluxineneyo, kwaye iipropathi zomatshini azifani.Kwangaxeshanye, ngenxa yesiqulatho segesi ephezulu kwintsimbi, ukuqina kuphantsi, ukubanda kwe-brittleness kunye nobuntununtunu bokwaluphala bukhulu kakhulu, kwaye ukusebenza kwe-welding nakho kubi.Ngoko ke, iipleyiti zetsimbi ezibilisayo azifanelekanga ukuvelisa izakhiwo ezidityanisiweyo kunye nezinye izakhiwo ezibalulekileyo ezithwala imithwalo yempembelelo kunye nokusebenza phantsi kweemeko zokushisa eziphantsi.

2. Ipleyiti yentsimbi ebulewe yintsimbi yentsimbi eyenziwe ngentsimbi eqhelekileyo ye-carbon structural ebulewe yintsimbi ngokuqengqeleka eshushu.Intsimbi ebulewe yintsimbi ekhutshwe ngokupheleleyo.Intsimbi etyhidiweyo ikhutshwe ngokupheleleyo kwi-ferromanganese, i-ferrosilicon kunye ne-aluminiyam phambi kokugalelwa.Umxholo we-oksijini wensimbi etyhidiweyo iphantsi (ngokuqhelekileyo i-0.002-0.003%), kwaye intsimbi etyhidiweyo izolile kwi-ingot mold.Akukho nto ibilisayo, ngoko ke igama lentsimbi ebuleweyo.Ngaphantsi kweemeko eziqhelekileyo zokusebenza, akukho bhubhu kwintsimbi ebuleweyo, kwaye isakhiwo siyafana kwaye sihlangene;ngenxa yomxholo we-oksijeni ephantsi, insimbi iqulethe i-oxide encinci inclusions, ubunyulu obuphezulu, i-brittleness ephantsi ebandayo kunye nokuthambekela kokuguga;ngelo xesha, ulwahlulo lwentsimbi ebulewe luncinci, Ukusebenza ngokulinganayo kunye nomgangatho uphezulu.Ukungalungi kwentsimbi ebuleweyo kukucutha okugxininisiweyo, isivuno esiphantsi kunye nexabiso eliphezulu.Ke ngoko, intsimbi ebuleweyo isetyenziswa ikakhulu kumacandelo amelana nempembelelo kumaqondo obushushu aphantsi, izakhiwo ezidityanisiweyo, kunye namanye amacandelo afuna amandla aphezulu.

Iipleyiti zetsimbi eziphantsi-alloy zombini zibulawa kunye neeplati zetsimbi ezibuleweyo.Ngenxa yamandla ayo aphezulu kunye nokusebenza okuphezulu, inokugcina intsimbi eninzi kunye nokunciphisa ubunzima besakhiwo, ukusetyenziswa kwayo kuye kwanda kakhulu.

5. Ipleyiti yentsimbi ekumgangatho ophezulu wekhabhoni:

I-high-quality carbon structural steel yintsimbi yekhabhoni enomxholo wekhabhoni ongaphantsi kwe-0.8%.Le ntsimbi iqulethe i-sulfure encinci, i-phosphorus kunye ne-non-metallic inclusions kune-carbon structural steel, kwaye ineempawu ezingcono zomatshini.

Umgangatho ophezulu we-carbon structural steel unokwahlulwa ngokweendidi ezintathu ngokweziqulatho zekhabhoni ezahlukeneyo: intsimbi ephantsi kwekhabhoni (C≤0.25%), intsimbi ephakathi kwekhabhoni (C yi-0.25-0.6%) kunye nentsimbi ephezulu yekhabhoni (C> 0.6) %).

Ngokomxholo ohlukeneyo we-manganese, i-high-quality carbon structural steel ingahlulwa ibe ngamaqela amabini: umxholo we-manganese oqhelekileyo (umxholo we-manganese 0.25% -0.8%) kunye nomxholo ophezulu we-manganese (umxholo we-manganese 0.70% -1.20%).Le yokugqibela inobuchwephesha obungcono.Ukusebenza kunye nokucubungula ukusebenza.

1. I-high-quality carbon structural steel sheet-rolled-rolled sheet kunye ne-steel strip Umgangatho ophezulu we-carbon structural steel hot-rolled thin steel sheet kunye ne-steel strip isetyenziswa kwi-automobile, i-aviation industry kunye namanye amacandelo.Imigangatho yayo yentsimbi yintsimbi: 08F, 10F, 15F;intsimbi ebulewe: 08, 08AL, 10, 15, 20, 25, 30, 35, 40, 45, 50.
