Seamless steel yeeb nkab kev kho cua sov txheej txheem

Kev kho cua sov txheej txheem ntawmseamless steel yeeb nkabyog cov txheej txheem uas hloov lub koom haum hlau sab hauv thiab cov khoom siv kho tshuab ntawm seamless steel yeeb nkab los ntawm cov txheej txheem ntawm cua sov, tuav thiab txias. Cov txheej txheem no txhawm rau txhim kho lub zog, toughness, hnav tsis kam thiab corrosion kuj ntawm cov yeeb nkab steel kom ua tau raws li qhov xav tau ntawm kev siv sib txawv.

 

Cov txheej txheem kev kho cua sov
1. Annealing: Seamless steel yeeb nkab yog rhuab saum toj no qhov tseem ceeb kub, tuav rau ib tug txaus lub sij hawm, thiab ces maj mam txias rau chav tsev kub.
Lub hom phiaj: Tshem tawm kev ntxhov siab sab hauv; txo hardness, txhim kho kev ua haujlwm; refine cov nplej, cov koom haum tsis sib xws; txhim kho toughness thiab plasticity.
Daim ntawv thov Scenario: Tsim nyog rau siab carbon steel thiab alloy steel yeeb nkab, siv rau lub sijhawm uas yuav tsum tau siab plasticity thiab toughness.

2. Normalizing: Cua sov seamless steel yeeb nkab rau 50-70 ° C saum toj no qhov tseem ceeb kub, tuav thiab txias ib txwm nyob rau hauv cov huab cua.
Lub hom phiaj: ua kom zoo dua cov nplej, cov koom haum tsis sib xws; txhim kho lub zog thiab hardness; txhim kho txiav thiab machinability.
Daim ntawv thov Scenario: Feem ntau yog siv rau nruab nrab carbon steel thiab tsis tshua muaj alloy steel, haum rau daim ntaub ntawv uas yuav tsum tau muaj zog, xws li pipelines thiab mechanical Cheebtsam.

3. Hardening: Seamless steel tubes yog rhuab saum toj no qhov tseem ceeb kub, cia sov thiab ces txias sai heev (xws li dej, roj los yog lwm yam xov xwm txias).
Lub hom phiaj: txhawm rau ua kom tawv thiab lub zog; kom hnav tsis kam.
Disadvantages: Tej zaum yuav ua rau cov khoom ua nkig thiab ua rau muaj kev ntxhov siab sab hauv.
Daim Ntawv Thov Scenario: Siv dav hauv kev tsim cov tshuab, cov cuab yeej thiab cov khoom hnav-tiv taus.

4. Tempering: Cua sov lub quenched seamless steel yeeb nkab mus rau ib tug haum kub hauv qab no qhov tseem ceeb kub, tuav thiab txias maj mam.
Lub hom phiaj: tshem tawm brittleness tom qab quenching; txo cov kev ntxhov siab sab hauv; txhim kho toughness thiab plasticity.
Daim ntawv thov Scenario: Feem ntau yog siv ua ke nrog quenching rau daim ntawv thov uas yuav tsum tau muaj zog thiab toughness.

 

Cov nyhuv ntawm kev kho cua sov ntawm kev ua haujlwm ntawmCarbon Seamless Steel Yeeb Nkab
1. Txhim kho lub zog, hardness thiab hnav tsis kam ntawm cov yeeb nkab steel; txhim khu lub toughness thiab plasticity ntawm steel yeeb nkab.

2. Ua kom zoo rau cov qauv nplej thiab ua kom lub koom haum steel zoo sib xws;

3. Kev kho cua sov tshem tawm cov impurities thiab oxides thiab txhim kho corrosion kuj ntawm cov yeeb nkab steel.

4. txhim kho lub machinability ntawm steel yeeb nkab los ntawm annealing los yog tempering, txo qhov nyuaj ntawm kev txiav thiab ua.

 

Kev siv thaj chaw ntawm seamless yeeb nkabKev kho cua sov
1. Roj thiab roj tsheb thauj mus los pipeline:
Lub tshav kub-kho seamless steel yeeb nkab muaj zog dua thiab corrosion kuj, thiab yog haum rau kev kub siab thiab hnyav ib puag ncig.

2. Machinery manufacturing kev lag luam:
Siv rau kev tsim khoom siab zog thiab siab toughness mechanical qhov chaw, xws li shafts, gears thiab lwm yam.

3. Boiler kav dej:
Thaum tshav kub kub-kho seamless steel yeeb nkab tuaj yeem tiv taus qhov kub thiab txias, feem ntau siv hauv boilers thiab kub exchangers.

4. Kev tsim kho engineering:
Siv nyob rau hauv zus tau tej cov high-strength structural thiab load-bearing qhov chaw.

5. Kev lag luam tsheb:
Siv nyob rau hauv kev tsim cov tsheb qhov chaw xws li tsav shafts thiab shock absorbers.
