Txoj kev txias-draw steel yeeb nkab extrusion txoj kev yog tso cov yeeb nkab uas muaj cua sov rau hauv lub tog raj kheej kaw, thiab cov pas nrig perforated thiab tus pas nrig extrusion txav mus ua ke kom extrude qhov extrusion los ntawm qhov me me tuag. txoj kev no
Cov kab me me steel yeeb nkab.
General-purpose seamless kav yog dov los ntawm cov pa roj carbon zoo tib yam steel, low-alloy structural steel los yog alloy structural steel. hauv paus
Extubation muab faib ua peb hom khoom:
1. Raws li tshuaj muaj pes tsawg leeg thiab txhua yam khoom;
2. Muab khoom raws li cov khoom siv kho tshuab;
3. Raws li kev ntsuas hydraulic. Cov yeeb nkab steel muab raws li thawj ob hom, yog tias lawv siv los tiv thaiv cov kua siab, kuj raug rau kev sim hydrostatic.
Cov ntsiab lus tseem ceeb rau kev ntxuav cov yeeb nkab txias txias:
1. Hnav cov khoom tiv thaiv kev ua haujlwm ua ntej khaws cov yeeb nkab txias txias. Kev tshuaj xyuas kom ntxaws ntawm qhov chaw ua haujlwm ntawm qhov chaw kuj tseem yuav tsum tau, feem ntau yog los xyuas seb lub sling ntawm cov yeeb nkab steel puas tiav.
Kev ua haujlwm tuaj yeem ua tiav tom qab ua tiav.
2. Thaum pickling, pickling tsuas yog siv hydrochloric acid pickling. Feem ntau, cov ntsiab lus ntawm hydrochloric acid yog 18 feem pua rau 20 feem pua.
3. Cov neeg ua haujlwm tseem yuav tsum paub txog cov kua qaub thiab qhov kub thiab txias thiab tonnage ntawm cov kua qaub txias-draw steel yeeb nkab hauv lub tank ua ntej ua haujlwm. Cov no tuaj yeem kuaj tau los ntawm kev siv cov cuab yeej ntsuas
Thib plaub, rau cov yeeb nkab uas muaj dej txias txias, qhov hnyav yuav tsum tau tswj ntawm 2 thiab 5 tons txhua zaus, thiab lub sijhawm yuav tsum tau tswj tsis pub dhau 5 mus rau 15 feeb. Lub sijhawm yuav tsum tau kho raws li qhov hnyav. Pickling
Nws kuj xav tau kev co tsis tu ncua. Thaum cov yeeb nkab tau qis rau hauv lub tank acid, yuav tsum muaj qee qhov kev xav kom tiv thaiv cov hydrochloric acid los ntawm kev ua phem rau tib neeg.
