Yuav ua li cas tswj cov hluav taws xob cua sov hlau nyob rau hauv lub qhov cub muaj?

1) Cov nplai oxide nyob rau hauv lub cub tawg yuav tsum tau ntxuav tas li nrog txhuam, txhuam los yog cov cua compressed kom tsis txhob poob ntawm cov khoom siv hlau thiab ua rau luv luv. Feem ntau, kev ntxuav yuav tsum tsis pub tsawg dua ib hlis ib zaug.

2) Tom qab siv lub sijhawm, cov khoom siv hluav taws xob tiv thaiv hluav taws xob xws li cov phaj hauv qab thiab cov tso tsheb hlau luam yog qhov zoo tshaj plaws los nqa thiab khob kom tshem tawm lawv cov oxide nplai kom tsis txhob tawg lossis faus ntawm cov khoom. Tshwj xeeb tshaj yog rau chromium-manganese-nitrogen steel, qhov spalling yog qhov hnyav dua nyob rau lub sijhawm tom qab.

3) Cov hniav qis ntawm lub thawv-hom qhov rooj thiab lub nplhaib txiav ntawm lub qhov cub-hom npog yuav tsum tau nruj nreem ntxig rau hauv cov xuab zeb foob zawj. Cov xuab zeb nyob rau hauv cov xuab zeb foob yuav tsum tsis txhob overfilled thiab yuav tsum tau theem. Yog tias xuab zeb poob rau hauv lub qhov cub, ntxuav nws raws sijhawm. Rau qhov kub tsis tshua muaj cua sov, ib txheej ntawm asbestos hlua liner tuaj yeem siv tau.

4) Lub crucible yuav tsum tau ncua sij hawm tawm ntawm sab nraud cua sov ntsev da dej rauv kom tshem tawm cov ntsev molten. Lub condensed ntsev ntawm qhov chaw ntawm lub caij tuaj yeem ntxuav nrog dej kub, thiab cov ntsev condensed ntawm lub txee tuaj yeem raug tshem tawm los ntawm kev khawb.

5) Lub npog ntawm lub qhov cub tooj dag yuav tsum tau txuas nrog kom nruj kom tsis txhob "tooj liab te" los ntawm kev poob rau hauv lub cub tawg thiab corroding cov khoom.

6) Tsis txhob kov cov hlau tsis muaj hlau xws li tooj liab, txhuas, zinc, tin, txhuas, thiab lwm yam, nrog rau cov khoom siv hluav taws xob. Txawm hais tias nws yog hmoov zoo, molten kua lossis chav, qhov corrosion ntawm cov ntsiab lus ntawm qhov kub thiab txias yog qhov teeb meem heev. Qhov no yog vim hais tias qhov eroded ib feem ua "qhov", qhov ntoo khaub lig ua me me, thiab thaum kawg burns tawm vim overheating.

7) Lub hau npog ntawm lub trolley rau nqa hluav taws xob annealing rauv yuav tsum tau nruj nreem nias kom tiv thaiv nws. Thaum lub casting yog annealed, xuab zeb poob rau hauv nws mus faus cov khoom thiab overheat thiab yaj. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau xyuas ntau zaus thiab tshem tawm cov xuab zeb hauv lub sijhawm.

8) Vim yog thermal expansion, txias contraction thiab creep elongation thaum cua sov thiab nres lub cub tawg, lub bolts ntawm cov hlau lead hlau clamp yog nquag oxidation thiab loosening, thiab yuav tsum tau xyuas thiab nruj nreem.

9) Lub qhov taub ntawm cov hlau lead-tawm yuav tsum tau thaiv kom nruj, kom tsis txhob xau cov roj tiv thaiv thiab hlawv ntawm no, ua rau lub cev pas nrig oxidize thiab tev tawm, ua rau tsis zoo ntawm cov hlau lead-tawm pas nrig thiab cov clamp.

10) Thaum lub qhov cub tsis muaj tank tsis muaj carburizing lossis qhov chaw tswj tau muaj CO tau siv, carbon dissociation yuav tshwm sim thiab ua rau luv luv. Yog li ntawd, lub qhov rooj cub tawg yuav tsum tau qhib ntau zaus los yog cov cua compressed yuav tsum tau siv rau tshuab tsis tu ncua, kom cov khoom siv hluav taws xob kub hnyiab tau hauv lub sijhawm.
