Yuav ua li cas txuas ntxiv mus rau lub sijhawm siv cov hluav taws xob hluav taws xob hluav taws xob kub kub
Kev kub siab hluav taws xob cua sov xov hlau feem ntau tuaj yeem ua los ntawm alloys xws li hlau chromium aluminium, npib tsib xee chromium, thiab lwm yam. Ua ntej tawm hauv lub Hoobkas, cov tub ntxhais kawm hauv kev lag luam feem ntau cuam tshuam rau kev kawm txog kev tiv thaiv kab mob antioxidant rau cov hluav taws xob cua sov cua sov. Txawm li cas los xij, thaum lub sij hawm kev thauj mus los, winding, installation thiab lwm yam txheej txheem, lawv yuav tsim thiab ua rau ib puag ncig kev puas tsuaj, yog li txo lub sij hawm siv ntawm high-kub hluav taws xob cua sov xov hlau. Yog li, peb yuav ua li cas txuas ntxiv mus txuas ntxiv lub sijhawm siv ntawm cov hluav taws xob hluav taws xob hluav taws xob kub kub? Tam sim no, cia peb saib ua ke nrog tus editor.
1. Tiv thaiv qhov kub thiab txias
High kub hluav taws xob cua sov hlau
Lub sijhawm ua haujlwm thiab qhov kub thiab txias ntawm cov cua sov xaim hluav taws xob yuav txo qis nrog kev hloov pauv kub, thiab cov khoom siv hluav taws xob ruaj khov yuav tsum raug xaiv.
2. Xaiv cov ntaub ntawv uas muaj cov kab hluav taws xob uas muaj qhov kub thiab txias
Lub thickness ntawm cov khoom ncaj qha cuam tshuam rau lub neej kev pab cuam ntawm hluav taws xob rauv sawb hlau. Raws li txoj kab nce ncaj qha, cov khoom siv hlau ntau ntxiv tsim cov oxides tshiab rau ib chav tsev ntawm qhov tsos. Yog li ntawd, nyob rau hauv tej qhov kub thiab txias, thicker high-temperature hluav taws xob cua sov hlau Cheebtsam yog ntev thiab thicker siv muaj ib tug thinner lifespan.
3. Kho raws li atmospheric ib puag ncig ntawm lub cub hluav taws xob thiab qhov kub thiab txias ntawm cov hluav taws xob cua sov hlau
Vim muaj kev cuam tshuam ntawm atmospheric ib puag ncig ntawm qee qhov feem ntau siv hluav taws xob rau qhov ua haujlwm kub ntawm cov cua sov, thiab kev pheej hmoo ntawm "ntsuab corrosion" ntawm 800-950 degree C thiab 1470-1740 degree F, nws yog Tsis tsim nyog siv Nicrotal hauv hluav taws xob rauv taws nrog CO tiv thaiv huab cua. Hauv qhov no, nws raug nquahu kom siv Kanthal alloy, tab sis nws yuav tsum tau ua ntej oxidized nyob rau hauv hluav taws xob furnaces ntawm 1050 degree C thiab 1920 degree F rau 7-10 teev, thiab high-temperature hluav taws xob cua sov yuav tsum periodically re oxidized.
4. Tiv thaiv kev yaig ntawm cov khoom, kua, thiab roj hauv kev lag luam thiab tswj hluav taws xob rauv taws
Cov impurities nyob rau hauv cov huab cua, xws li roj, plua plav, volatiles, los yog carbon deposits, yuav ua rau puas cua sov ntsiab. Sulfur yog teeb meem rau tag nrho cov nickel alloys. Cov tshuaj chlorine hauv ntau lub xeev tuaj yeem ua rau KANTHAL thiab NIKROTHAL alloys puas tsuaj, thiab cov tshuaj hlau los yog ntsev tuaj yeem ua rau cov cua sov puas.
