VL/EH32 Nkoj Lub Tsev Phaj

 

 

Qhov zoo ntawm shipbuilding steel phaj VL / EH32 feem ntau muaj cov hauv qab no:

 

I. Cov kev cai pom zoo

 

Flatness: Qhov saum npoo ntawm cov hlau phaj yuav tsum tiaj tus thiab yuav tsum tsis muaj qhov tsis sib xws. Qhov no yog qhov tseem ceeb rau kev ua haujlwm tom ntej (xws li vuam, txiav, thiab lwm yam) thiab kev teeb tsa hauv lub nkoj. Yog tias qhov chaw tsis tiaj tus, nws tuaj yeem cuam tshuam qhov vuam zoo, ua rau cov vuam tsis ruaj khov lossis txawm tias muaj teeb meem xws li tawg. Nyob rau tib lub sijhawm, qhov tsis sib xws ntawm qhov chaw kuj tseem cuam tshuam rau kev zoo nkauj thiab kev ua haujlwm tag nrho ntawm lub nkoj qauv.

Tsis muaj kab nrib pleb: Yuav tsum tsis muaj kab nrib pleb ntawm qhov chaw. Cov kab nrib pleb yog qhov tsis xws luag uas yuav txo tau lub zog thiab toughness ntawm steel phaj. Thaum siv lub nkoj, nws yuav ua rau muaj kev puas tsuaj ntawm lub nkoj thiab ua rau muaj kev phom sij rau kev nyab xeeb ntawm lub nkoj. Txawm tias cov kab nrib pleb me me tuaj yeem nthuav dav hauv kev ntxhov siab thiab thaum kawg ua rau muaj xwm txheej loj.

Tsis muaj folding: Yuav tsum tsis muaj qhov tshwm sim folding ntawm lub phaj steel. Folding yuav ua rau lub zos thickness ntawm steel phaj thiab cuam tshuam rau cov uniformity thiab stability ntawm cov qauv. Hauv kev tsim cov nkoj, qhov folding yuav dhau los ua qhov kev ntxhov siab ntawm qhov chaw, txo cov kabmob muaj peev xwm ntawm cov phaj steel thiab ua rau muaj kev pheej hmoo ntawm kev puas tsuaj ntawm lub nkoj.

 

II. Qhov yuav tsum tau ua kom huv huv

 

Tsis muaj roj stains: Yuav tsum tsis muaj roj stains lossis lwm yam impurities ntawm lub phaj hlau. Cov roj stains yuav cuam tshuam qhov vuam zoo thiab txo lub zog ntawm qhov sib koom ua ke. Thaum lub sij hawm vuam txheej txheem, cov roj stains yuav ua rau muaj qhov tsis xws luag xws li pores thiab slag inclusions, txo cov compactness thiab corrosion kuj ntawm vuam. Tsis tas li ntawd, cov roj stains kuj tseem tuaj yeem cuam tshuam cov adhesion ntawm cov txheej txheem thiab ua rau cov txheej txheem tiv thaiv corrosion tsis tuaj yeem tiv thaiv cov phaj hlau zoo.

Tsis muaj xeb: Qhov saum npoo yuav tsum muaj xeb tsawg li sai tau. Txawm hais tias shipbuilding steel daim hlau feem ntau raug kho los tiv thaiv corrosion, ntau xeb yuav cuam tshuam rau cov nyhuv ntawm cov tshuaj tiv thaiv corrosion thiab ua kom lub corrosion ntawm steel phaj. Thaum lub sij hawm siv lub nkoj, xeb kuj tuaj yeem poob, ua paug rau ib puag ncig, thiab tuaj yeem thaiv lub nkoj lub qhov dej thiab lwm yam khoom siv.

Tsis muaj nplai: Cov phaj hlau tuaj yeem tsim cov nplai thaum lub sijhawm tsim khoom, thiab cov nplai no yuav tsum tau muab tshem tawm. Lub xub ntiag ntawm nplai yuav cuam tshuam rau qhov zoo ntawm qhov chaw thiab kev ua haujlwm ntawm cov phaj steel, txo nws cov corrosion kuj thiab vuam kev ua tau zoo. Thaum lub sij hawm welding, nplai yuav muab sib xyaw rau hauv qhov vuam thiab tsim qhov tsis xws luag xws li slag inclusions, cuam tshuam qhov vuam zoo.

 

III. Dimensional raug qhov yuav tsum tau

 

Uniform thickness: Lub thickness ntawm steel phaj yuav tsum tau khaws cia nyob rau hauv ib tug ntau yam ntawm kev teev. Cov tuab tuab tsis sib xws yuav cuam tshuam rau lub zog thiab ruaj khov ntawm lub nkoj qauv thiab tuaj yeem ua rau muaj kev ntxhov siab ntawm qhov sib txawv, ua rau cov qauv kev puas tsuaj. Nyob rau tib lub sijhawm, cov thickness tsis sib xws tseem yuav ua rau muaj kev nyuaj rau kev ua thiab kev teeb tsa thiab ua rau kev tsim kho nyuaj thiab nqi.

Kev kam rau me me hauv qhov dav thiab qhov ntev: Qhov dav thiab ntev ntawm cov phaj steel yuav tsum ua tau raws li cov qauv tsim, thiab kev kam rau siab yuav tsum tau tswj nyob rau hauv ib qho me me. Kev ua siab ntev ntev ntawm qhov dav thiab qhov ntev yuav ua rau muaj teeb meem xws li xoob splicing thiab qhov loj me tsis sib haum thaum lub sij hawm tsim nkoj, cuam tshuam rau cov qauv kev ncaj ncees thiab cov tsos zoo ntawm lub nkoj.

IV. Lwm yam kev xav tau

 

Cov cim meej meej: Lub npoo ntawm cov hlau phaj yuav tsum tau cim nrog cov ntsiab lus meej, qauv, cov khoom siv, thiab lwm yam kom paub meej thiab tswj tau yooj yim. Cov cim no tseem ceeb heev rau cov khoom siv traceability thiab kev tswj kom zoo thaum lub caij nkoj tsim.

Nruab nrab roughness: Qhov saum npoo roughness yuav tsum ua tau raws li cov qauv tsim nyog. Tsim nyog qhov chaw roughness tuaj yeem txhim kho qhov adhesion ntawm cov coatings thiab txhim khu kev tiv thaiv corrosion. Txawm li cas los xij, yog tias qhov roughness loj dhau lawm, nws yuav cuam tshuam rau qhov zoo ntawm cov phaj steel thiab tej zaum yuav tsis siv rau qee lub sijhawm tshwj xeeb (xws li qhov chaw uas yuav tsum tau muaj qhov du).
