1. Dab tsi yog qhov "Killed" steel mob, thiab vim li cas nws thiaj siv?
Cov hlau tua tau tag nrho deoxidized thaum lub sij hawm steelmaking. Qhov no ua rau cov hlau ntau homogeneous nrog cov hnab ntim roj tsawg (porosity) thiab cov tshuaj lom neeg ntau dua, uas yog qhov tseem ceeb rau kev ncaj ncees ntawm cov kav dej seamless, tshwj xeeb tshaj yog rau cov ntawv thov tseem ceeb.
2. Dab tsi yog qhov kev sib tw tseem ceeb hauv kev xa khoom loj - txoj kab uas hla seamless kav?
Kev tsim cov kav dej loj heev seamless (piv txwv li, tshaj 24 ntiv tes) yog qhov nyuaj heev thiab raug nqi vim muaj kev txwv nyob rau hauv billet loj, tho machinery, thiab tuav. Rau txoj kab uas hla loj, welded kav yog qhov kev xaiv ntau dua thiab kev lag luam.
3. Yuav ua li cas yog qhov nto tiav ntawm cov yeeb nkab seamless?
Qhov saum npoo tuaj yeem muaj lub nplai zeb los ntawm kub dov. Rau kev ua kom huv si, cov kav dej tuaj yeem raug muab tshem tawm (acid- ntxuav) los yog abrasive blasted. Txias- cov kav dej muaj qhov ua kom zoo dua, ci tiav.
4. Qhov kev pheej hmoo ntawm Lamellar Tearing hauv cov kav dej seamless yog dab tsi?
Lamellar Tearing yog ib qho kev pheej hmoo feem ntau cuam tshuam nrog cov pob qij txha welded hauv cov phaj tuab uas tsis muaj -cov hlau muaj nyob hauv. Txij li cov kav dej seamless tsis muaj longitudinal weld, lawv yog qhov tsis muaj kev pheej hmoo ntawm lamellar tearing raws lawv qhov ntev.
5. Cov kav dej seamless puas tuaj yeem galvanized?
Yog lawm, seamless carbon steel kav tuaj yeem kub -dip galvanized los muab zinc txheej rau kev tiv thaiv corrosion. Qhov no yog ib qho kev siv sab nraum zoov lossis kev faib dej, txawm tias qhov siab - txheej txheem kub tuaj yeem cuam tshuam me ntsis rau cov khoom siv kho tshuab.
