Ngaba uyazi izinto ezichaphazela iipropati zoomatshini ze-hot rolled steel coil?

Xa uvelisaiikhoyili zentsimbi eziqengqelekayo ezishushu, kubalulekile ukuqonda izinto ezichaphazela iimpawu zayo zoomatshini. Into ebalulekileyo engenakuyityeshelwa bubushushu. Amaqondo obushushu okufudumeza nokupholisa eekhoyili zentsimbi adlala indima ebalulekileyo ekumiseleni umgangatho kunye nokusebenza kweekhoyili zentsimbi. Kweli nqaku sijonga ngokunzulu impembelelo yobushushu kwiimpawu zoomatshini zekhoyili yentsimbi esandul’ ukutshiswa eshushu.
Inkalo yokuqala echaphazeleka kukusetyenziswa kobushushu yintsimbi ye-hrc yexabiso. Ukulungiswa kobushushu kudla ngokufuna amandla ongezelelweyo kunye nezixhobo ezikhethekileyo, nto leyo enokuchaphazela ixabiso lokugqibela lemveliso. Nangona kunjalo, ukubaluleka kwezi ndlela zonyango kukuba zibonelela ngeempawu zoomatshini eziphuculweyo. Ngokubeka iikhoyili zentsimbi kwinkqubo yokufudumeza nokupholisa elawulwayo, kunokwenzeka ukutshintsha isakhiwo sayo kwaye kwandiswe amandla ayo ngokubanzi, ubulukhuni kunye nokuguquguquka.
Intsimbi eqhotsiweyo eshushu kakhulu kwiikhoyili, ingakumbi ezo zenziwe ngentsimbi ye-Q235B, ziphathwa ngononophelo lobushushu ukuze ziphucule iipropati zazo zoomatshini. Inkqubo yonyango lobushushu ibandakanya ukufudumeza ikhoyili kubushushu obuthile (ngesiqhelo ngaphezulu kobushushu bayo bokuphinda i-recrystallization) ize emva koko iyicime ngokukhawuleza. Oku kupholisa ngokukhawuleza kunceda ukufezekisa isakhiwo esincinci ngaphakathi kwentsimbi, nto leyo eyonyusa amandla nokuqina.
Iimpawu zoomatshini zeIshidi lentsimbi elihonjisiweyo eliphambili elishushu kwiikhoyili q235bzikwachaphazeleka lizinga lokupholisa emva kwenkqubo yokufudumeza. Ukupholisa okucothayo kukhokelela ekwakhiweni kwesakhiwo esirhabaxa, nto leyo echaphazela kakubi amandla oomatshini entsimbi. Kwelinye icala, ukupholisa ngokukhawuleza kunceda ekuphuculeni isakhiwo sengqolowa kunye nokuphucula iimpawu zoomatshini ngokubanzi.

Ukuqinisekisa umgangatho ophezulu, kubalulekile ukusebenza nabathengisi abathembekileyo abanamathela kwimigangatho engqongqo yokuvelisa. Ngokufumana i-hot rolled steel sheet kwi-coil prime kumvelisi othembekileyo, unokuqiniseka ngokuhambelana kunye nokuthembeka kweempawu zoomatshini zentsimbi yakho. Ukongeza, abathengisi abathembekileyo badla ngokukwazi ukubonelela ngamaxabiso akhuphisanayo kwiimveliso zabo ngaphandle kokubeka emngciphekweni umgangatho.
Ngamafutshane, ubushushu budlala indima ebalulekileyo ekumiseleni iimpawu zoomatshini zeekhoyili zentsimbi ezigoqwe ngobushushu. Ngenkqubo yokufudumeza nokupholisa elawulwayo, amandla, ubulukhuni kunye nokuguquguquka kwentsimbi kunokulungiswa. Kubalulekile ukukhetha umthengisi obeka phambili umgangatho kunye nokuhambelana xa evelisa iikhoyili zentsimbi ezigoqwe ngobushushu eziphezulu. Ngokwenza oku, uqinisekisa ukuba ufumana imveliso engcono ngexabiso elikhuphisanayo.
