Yuav ua li cas tswj cov hluav taws xob cua sov hlau nyob rau hauv lub tsev lag luam kiln nquag?
1) Cov nplai oxide nyob rau hauv lub cub tawg yuav tsum nquag ntxuav nrog txhuam, txhuam los yog compressed cua kom tsis txhob muaj luv luv Circuit Court poob ntawm cov hlau alloy, thiab feem ntau yuav tsum tsis txhob ntxuav tsawg tshaj li ib hlis ib zaug.
2) Txhua lub sij hawm cov khoom siv hluav taws xob tiv thaiv hluav taws xob xws li cov phaj hauv qab thiab lub tshuab hluav taws xob siv rau lub sijhawm, nws yog qhov zoo tshaj los nqa thiab khob kom tshem tawm cov hlau oxide nplai kom tsis txhob tawg lossis faus cov khoom. Tshwj xeeb, chromium-manganese nitrogen steel yog qhov hnyav dua thaum siv rau theem tom qab.
3) Cov hniav hauv qab ntawm lub thawv rauv qhov rooj thiab lub nplhaib riam ntawm lub qhov cub zoo yuav tsum tau nruj nreem ntxig rau hauv cov xuab zeb sealing tank, thiab cov xuab zeb hauv cov xuab zeb foob tsis tuaj yeem overfilled thiab yuav tsum tiaj tus. Yog tias cov xuab zeb poob rau hauv qhov cub, nws yuav tsum tau muab ntxuav kom huv si raws sijhawm. Rau cryogenic furnaces, ib txheej ntawm asbestos hlua liner tuaj yeem siv tau.
4) Sab nraud kub ntsev da dej rauv yuav tsum tsis tu ncua hoisted tawm ntawm lub crucible kom tshem tawm molten ntsev. Lub condensate ntsev nyob rau saum npoo ntawm lub caij tuaj yeem ntxuav nrog dej kub, thiab cov ntsev condensed ntawm lub cib tuaj yeem raug tshem tawm los ntawm kev khawb.
5) Lub hau ntawm lub qhov cub hluav taws xob hluav taws xob yuav tsum tau nruj nreem kaw kom tsis txhob "tooj liab te" poob rau hauv qhov cub thiab eroding cov khoom.
6) Tsis txhob sib cuag nrog cov hlau tsis muaj hlau xws li tooj liab, txhuas, zinc, tin, thiab txhuas nrog cov khoom siv hluav taws xob cua sov, txawm tias nws yog hmoov zoo, yaj los yog ncu, qhov yaig ntawm cov khoom ntawm qhov kub thiab txias yog qhov txaus ntshai heev. Qhov no yog vim qhov eroded ib feem ntawm "pockmarked pit", qhov cross-section ua me me, thiab thaum kawg nws burns tawm vim overheating.
7) Lub trolley npog phaj 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 thiab cov khoom faus thiab overheated melting tshwm sim. 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 thiab contraction thiab creep elongation thaum cua sov thiab nres lub cub tawg, lub bolts ntawm tus pas nrig hlau clips yog nquag oxidation loosening, thiab yuav tsum tau xyuas thiab nruj nreem.
9) Lub qhov ntawm cov pas nrig yuav tsum tau nruj nreem thaiv kom tsis txhob muaj cov pa tiv thaiv hluav taws kub ntawm no, ua rau lub cev pas nrig oxidize thiab tev tawm, kom cov pas nrig thiab cov clamp tsis zoo.
10) Nyob rau hauv tankless carburizing furnaces los yog thaum siv ib tug tswj chaw uas muaj CO, carbon dissociation yuav tshwm sim thiab ua rau luv luv circuits. Yog li ntawd, lub qhov rooj rauv yuav tsum tau qhib tsis tu ncua los yog tsis tu ncua purged nrog compressed cua kom hlawv cov pa roj carbon combustion nyob rau hauv lub sij hawm.
