1. Tom qab tso nyiaj ib feem peb ntawm cov nqi ntawm lub hauv paus ntawm lub cub hluav taws xob, cov khoom lag luam suav yuav tsum muab tso rau ntawm nws, ua raws li cov nqi ntxiv raws li qhov xav tau. Nyob rau hauv cov xwm txheej uas tus nqi siab yog qhov tseem ceeb, nws yog ib qho tseem ceeb rau compress ib feem ntawm cov nqi fragmented tiv thaiv lub recarburizer kom txo tau qhov surfacing thiab kom ntseeg tau tias qhov kev pom zoo.
2. Kev sib txuas ntawm cov khoom siv yog raws li hauv qab no: ib qho me me ntawm cov khoom siv hlau, recarburizer, steel seem, thiab cov khoom siv rov ua dua tshiab. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qhov nqus ntawm cov recarburizer tshaj 88%, nrog rau qhov kub txog 1560 degree, tso cai rau tshem tawm slag los ntawm lub qhov cub. Nws yog ib advisable kom tsis txhob tshem tawm tag nrho cov molten hlau los ntawm lub cub tawg; es, qee cov hlau molten yuav tsum tau khaws cia. Tom qab ntawd, lub recarburizer, hlau filings, steel seem, thiab lwm yam ntaub ntawv yuav muab ntxiv. Nws yog qhov zoo los tuav ib feem ntawm cov hlau molten nyob rau hauv qab ntawm lub cub tawg los yog tso ib co hlau pins rau hauv qab kom txhim khu kev nqus. Kev siv cov txheej txheem ntxuav uas txo qhov nqus ntawm cov khoom no tsis pom zoo. Tsis tas li ntawd, nws yog ib qho tseem ceeb kom tsis txhob npog graphite npua hlau nrog slag thaum lub sij hawm melting txheej txheem, vim qhov no yuav ua rau cov khib nyiab slag thiab tsis zoo rau cov pa roj carbon uptake.
Nyob rau hauv kev sib piv rau cov tsoos cam khwb cia hlau, graphite carburizers muaj ntau yam zoo:
1. Cov khoom no tsis tso cov khoom seem thaum siv, ua rau muaj kev siv siab;
2. Nws yog tus neeg siv-phooj ywg hauv cov txheej txheem ntau lawm, ua rau kev txuag nqi;
3. Cov ntsiab lus phosphorus thiab sulfur yog qis dua li ntawm cov hlau cam khwb cia, pab txhawb kev ua haujlwm ruaj khov;
4. Daim ntawv thov ntawm graphite carburizers tuaj yeem txo cov nqi cuam tshuam nrog cov castings.
