Dab tsi yog Cov Txheej Txheem Ntawm Cov Hlau Stainless Seamless Yeeb Nkab
Apr 06, 2022| 1. Kub dov (extruded seamless steel yeeb nkab): round tube billet → cua sov → perforation → peb-yob skew dov, nruam dov los yog extrusion → yeeb nkab tshem tawm → sizing (los yog txoj kab uas hla txo) → txias → straightening → hydraulic kuaj (los yog flaw detection ) → cim → warehousing
Cov khoom siv raw rau dov seamless raj yog ib puag ncig lub raj dawb, uas yog txiav los ntawm lub tshuab txiav mus rau hauv ib lub billet nrog ntev li ntawm 1 meter, thiab xa mus rau lub cub tawg rau cua sov los ntawm txoj siv conveyor. Cov nqaij npuas kib tau muab tso rau hauv qhov cub thiab ua kom sov li ntawm 1200 degrees Celsius. Cov roj yog hydrogen lossis acetylene. Kev tswj qhov kub thiab txias hauv qhov cub yog qhov teeb meem tseem ceeb. Tom qab lub round raj dawb paug tawm ntawm lub cub tawg, nws yuav tsum tau pierced los ntawm lub siab piercer. Feem ntau, ntau lub tshuab xuas nrig ntaus yog lub conical roller punching tshuab. Lub tshuab xuas nrig ntaus tshuab no muaj kev ua haujlwm siab ntau lawm, cov khoom lag luam zoo, qhov loj ntawm perforation thiab txoj kab uas hla nthuav dav, thiab tuaj yeem hnav ntau qib steel. Tom qab perforation, lub round raj dawb paug yog successively hla-dov, tsis tu ncua dov los yog extruded los ntawm peb yob. Tom qab extrusion, lub raj yuav tsum tau muab tshem tawm thiab sizing. Lub tshuab sizing rotates rau hauv steel billet ntawm kev kub ceev los ntawm conical laum me ntsis rau punch qhov los tsim steel kav. Sab hauv txoj kab uas hla ntawm cov yeeb nkab steel yog txiav txim siab los ntawm sab nraud ntawm lub laum me ntsis ntawm lub tshuab sizing. Tom qab cov yeeb nkab steel yog sizing, nws nkag mus rau hauv lub txias ntauwd thiab txias los ntawm cov dej tsuag. Tom qab cov yeeb nkab steel yog txias, nws yuav ncaj. Tom qab straightening, cov yeeb nkab steel raug xa mus rau cov hlau tsis haum (lossis kuaj hydraulic) los ntawm txoj siv conveyor rau kev kuaj pom qhov tsis zoo. Yog tias muaj cov kab nrib pleb, npuas thiab lwm yam teeb meem hauv cov yeeb nkab steel, nws yuav raug kuaj pom. Tom qab kev soj ntsuam zoo ntawm cov yeeb nkab steel, nws yuav tsum dhau qhov kev xaiv nruj heev. Tom qab kev soj ntsuam zoo ntawm cov yeeb nkab steel, tus lej xov tooj, specification, ntau lawm batch naj npawb, thiab lwm yam yog txau nrog cov xim. Thiab nqa mus rau hauv lub warehouse los ntawm crane.
2. Cold drawn (dov) seamless steel yeeb nkab: round tube billet → cua sov → perforation → heading → annealing → pickling → oiling (tooj liab plating) → multi-pass txias drawing (txias dov) → billet → tshav kub kho → straightening → Hydrostatic test (Kev kuaj pom qhov tsis haum) → Kev cim → Cia.
Txoj kev dov ntawm cov khaub thuas rub (dov) seamless steel yeeb nkab yog qhov nyuaj tshaj li kub dov (extruded seamless steel yeeb nkab). Thawj peb kauj ruam ntawm lawv cov txheej txheem ntau lawm yog qhov pib zoo ib yam. Qhov sib txawv pib ntawm theem plaub. Tom qab lub voj voog puag ncig yog emptied, nws yuav tsum tau taub hau thiab annealed. Tom qab annealing, ib tug tshwj xeeb acid kua yuav tsum tau siv rau pickling. Tom qab pickling, thov roj. Tom qab ntawd nws yog ua raws li los ntawm ntau dhau ntawm kev kos duab txias (txias dov) thiab tom qab ntawd billet raj, kev kho cua sov tshwj xeeb. Tom qab kev kho cua sov, nws yog straightened.
