Nws paub zoo tias qhov tsos, kev siv tau thiab lub neej ua haujlwm ntawm cov khoom yog qhov qhia ncaj qha ntawm cov khoom ua haujlwm, thiab yog peb yam tseem ceeb rau kev txiav txim siab qhov zoo thiab qhov tsis zoo ntawm cov khoom. Hauv tsab ntawv kawg, peb tau qhia rau koj txog kev txhim kho ntawm cov txheej txheem tsim khoom ntawm Heli Heavy Industries lub rooj cob qhia thiab qhov chaw ntawm kev coj ua yav tom ntej nrog lub npe ntawm "Kev Txhim Kho Tshiab, Kev Hloov Tshiab". Hauv tsab ntawv no, peb yuav qhia rau koj txog Heli Heavy Industries cov khoom los ntawm cov ntaub ntawv thiab cov txheej txheem qub dua.
Cov ntsiab lus ntawm cov tshuaj lom neeg yeej ib txwm yog qhov ntsuas ntawm qhov zoo ntawm cov khoom siv hlau. Piv txwv li, kev nce ntxiv ntawm cov pa roj carbon ntawm cov hlau yuav ua rau cov hlau muaj zog thiab lub zog tensile ntau dua, thaum txo nws cov plasticity thiab cov yam ntxwv cuam tshuam.
Ntawm cov kab ntau lawm ntawm Heli Heavy Industry, muaj ob lub chaw kuaj mob. Lub chaw kuaj mob thawj zaug nyob hauv lub chaw tsim khoom, thiab yog lub luag haujlwm rau kev tshuaj xyuas cov khoom xyaw thiab kev tshuaj xyuas cov khoom seem. Lub chaw kuaj mob thib ob tau teeb tsa hauv Heli. Lub chaw ua haujlwm tsim khoom ntawm Li Heavy Industry feem ntau yog lub luag haujlwm rau kev tshuaj xyuas cov qauv ntawm cov khoom tiav thiab kev pab tshuaj xyuas cov txheej txheem kho cua sov. Lub chaw kuaj mob muaj lub tshuab ntsuas carbon thiab sulfur, lub tshuab ntsuas ntau yam ntse, lub tshuab kuaj metallurgical, thiab lwm yam.
6801-BZ/C Arc Combustion Carbon thiab Sulfur Analyzer
Lub tshuab ntsuas pa roj carbon thiab sulfur 6801-BZ/C arc combustion carbon thiab sulfur yuav tshuaj xyuas cov pa roj carbon thiab sulfur hauv cov khoom siv kom raug. Ntxiv rau qhov cuam tshuam ntawm carbon rau qhov tawv thiab plasticity ntawm cov hlau, nws kuj cuam tshuam rau qhov tsis kam ntawm cov hlau hauv huab cua. Hauv ib puag ncig sab nraum zoov, cov pa roj carbon ntau dua, qhov yuav muaj feem ntau dua rau nws yuav raug xeb. Yog li ntawd, kev txiav txim siab ntawm cov pa roj carbon yog ib kauj ruam tsim nyog hauv kev tsim cov hlau. Sulfur kuj yog ib qho khoom phom sij hauv qab qhov xwm txheej ib txwm muaj. Nws ua rau cov hlau tsim cov khoom kub brittleness, txo cov ductility thiab toughness ntawm cov hlau, thiab ua rau tawg thaum lub sijhawm forging thiab dov. Sulfur kuj ua rau kev ua haujlwm vuam tsis zoo, txo qhov tsis kam ntawm corrosion. Txawm li cas los xij, ntxiv 0.08-0.20% sulfur rau cov hlau tuaj yeem txhim kho kev siv tshuab thiab feem ntau hu ua cov hlau txiav dawb.
6811A lub tshuab ntsuas ntau yam ntse
Lub tshuab ntsuas ntau yam ntse 6811A tuaj yeem ntsuas cov ntsiab lus ntawm ntau yam tshuaj lom neeg xws li manganese (Mu), silicon (Si), thiab chromium (Cr). Manganese yog ib qho tshuaj deoxidizer thiab desulfurizer zoo hauv cov txheej txheem ua hlau. Ntxiv cov manganese kom txaus tuaj yeem txhim kho kev hnav tsis kam ntawm hlau. Silicon yog ib qho tshuaj txo qis zoo thiab deoxidizer. Tib lub sijhawm, silicon tuaj yeem ua rau cov hlau elastic ntau ntxiv. Chromium yog ib qho tseem ceeb ntawm cov hlau tsis xeb thiab cov hlau tiv taus kub. Nws tuaj yeem ua rau cov hlau tawv thiab tiv taus xeb, tab sis tib lub sijhawm txo cov yas. Yog li ntawd, qee qhov kev tawg ntawm hlau uas tshwm sim thaum lub sijhawm kho cua sov yuav muaj cov ntsiab lus chromium ntau dhau.
Lub tshuab kuaj hlau
Hauv kev tsim cov cheeb tsam plaub lub log, cov khoom siv ntawm lub hauv paus log txhawb nqa, lub hau log txhawb nqa sab thiab lub log txhawb nqa yog hlau ductile, uas muaj qhov xav tau siab rau tus nqi spheroidization. Lub tshuab microscope metallurgical tuaj yeem saib ncaj qha tus nqi spheroidization ntawm cov khoom.
Ntxiv rau, nickel (Ni), molybdenum (Mo), titanium (Ti), vanadium (V), tungsten (W), niobium (Nb), cobalt (Co), tooj liab (Cu), txhuas (Al), Cov ntsiab lus xws li boron (B), nitrogen (N), thiab av tsis tshua muaj (Xt) yuav muaj feem cuam tshuam rau kev ua tau zoo ntawm cov hlau thiab yuav tsum tau tswj hwm hauv qee qhov ntau.
Ob lub chaw soj nstuam zoo li ob lub chaw kuaj xyuas kev lis kev cai, saib xyuas Heli cov khoom siv tas li, tiv thaiv kev tawm ntawm txhua yam khoom tsis zoo, thiab xa cov khoom tsim nyog thiab zoo rau cov neeg siv khoom.
