Ob txheej txheem JCOE thiab RBE txheej txheem yog cov txheej txheem steel yeeb nkab siv los ua cov kav dej ntev.
1, Cov txheej txheem JCOE (tseem hu ua JCOE txheej txheem) yog cov txheej txheem kub-dov coiled ncaj seam welded yeeb nkab txheej txheem. Nws lub npe tag nrho yog "J-shaped dabtsi yog khoov, C-shaped forming, O-shaped retraction, thiab E-shaped expansion". Cov hlau phaj yog tsim rau ntau yam txheej txheem xws li khoov, sib sau, thim rov qab thiab nthuav dav. Cov txheej txheem no feem ntau tsim nyog rau kev tsim cov kav hlau steel nrog txoj kab uas hla loj, siab siab thiab loj phab ntsa tuab. Cov txheej txheem JCOE tuaj yeem tsim cov kav hlau nrog cov kab uas hla ntawm 406mm txog 1422mm thiab phab ntsa tuab ntawm 6mm txog 80mm.
2, Cov txheej txheem RBE yog cov txheej txheem tsim cov kav ntev ntev, thiab nws lub npe puv yog "Rov qab khoov thiab nthuav dav". Cov txheej txheem no tsuas yog ua tiav los ntawm thawj zaug khoov lub phaj kub-kuav los tiag rau hauv U zoo, tom qab ntawd thim rov qab khoov rau hauv cov hlua ncaj nraim welded yeeb nkab, thiab ua cov txheej txheem tom ntej xws li vuam, annealing, straightening, thiab flaw detection. Cov txheej txheem tsim nyog rau kev tsim cov kav hlau steel nrog txoj kab uas hla ntawm 406mm txog 1626mm thiab phab ntsa tuab ntawm 6mm txog 65mm.
Yog li ntawd, qhov sib txawv ntawm cov txheej txheem JCOE thiab cov txheej txheem RBE yog nyob rau hauv lawv cov txheej txheem sib txawv ntawm cov yeeb nkab ua, thiab txoj kab uas hla thiab phab ntsa tuab ntawm cov yeeb nkab steel tsim kuj txawv me ntsis.
