Q345 / S355JR Steel phaj Kub Rolled Mild Steel Sheet Rau Kho Kom Zoo Nkauj Thiab Siv Cov Duab

Cov lus piav qhia luv luv:

Carbon Steel Phaj yog ib lub phaj steel tsis muaj alhoying ntsiab, lossis cov phaj steel nrog tsuas MN. Nws yog hom hlau nrog cov ntsiab lus carbon muaj tsawg dua 2.11% thiab tsis muaj ntxiv ntawm cov hlau cov ntsiab lus. Nws kuj tseem tuaj yeem hu ua cov pa roj carbon hlau lossis cov hlau. Dawb steel. Ntxiv rau cov pa roj carbon, tseem muaj ib qho me me ntawm silicon, manganese, leej faj, phosphorus thiab lwm cov ntsiab lus hauv nws. Qhov ntau dua cov ntsiab lus carbon, qhov zoo dua lub hardness thiab lub zog, tab sis cov vacity yuav mob heev.

Qhov Zoo Ntawm Cov Pa Roj Carbon Hlau Phaj

1. Tom qab kev kho cua sov, lub hardness thiab hnav tsis kam tuaj yeem hloov kho.

2. Lub hardness yog qhov tsim nyog thaum lub sij hawm annealing, thiab lub contamility yog qhov zoo.

3. Nws cov ntaub ntawv nyoos muaj ntau heev, yog li nws yooj yim mus nrhiav, yog li cov nqi tsim tsis yog siab.

Carbon Steel Phaj Kev Kawm Ntawv

1. Raws li daim ntawv thov, nws tuaj yeem muab faib ua peb pawg: qauv, cuab yeej, thiab cov qauv sib xyaw dawb.

2. Raws li txoj kev smelting, nws tuaj yeem faib ua peb hom: Qhib cov hlau, Converter steel thiab hluav taws xob rauv steel

3. Raws li txoj kev deoxidation, nws tuaj yeem faib ua cov hlau npau npau, tua cov hlau, cov hlau tua ib nrab thiab cov hlau tshwj xeeb.

4. Raws li cov pa roj carbon. Nws tuaj yeem faib ua peb hom: cov pa roj carbon ntau, cov carbon nruab nrab thiab cov roj carbon thiab cov roj carbon ntau.

Khoom Paub meej

Cov hlau tuaj yeem muab faib ua cov hlau tsis muaj roj, nruab nrab cov pa roj carbon thiab cov roj carbon hlau. Tsawg Carbon Hlau - Cov ntsiab lus carbon feem ntau tsawg dua 0.25%; Nruab Nrab Carbon Steel - Cov ntsiab lus carbon ntau feem ntau ntawm 0.25 thiab 0.60%; Cov pa roj carbon hlau siab - cov ntsiab lus carbon ntau dua ntau dua 0.60%.
