Rau qhov tshwm sim tawg ntawm boiler, peb yuav tsum xub nrhiav qhov laj thawj, los daws qhov teeb meem. Kab lus no yuav piav qhia rau koj txog qhov ua rau tawg tom qab lub teeb rwb thaiv tsev castable refractory tsev rauv:
1. Qhov "grey-dej piv" ntawm castable refractories tsis tau raug tswj kom tsim nyog hauv cov txheej txheem sib xyaw:
Tom qab cov khoom tsim, qhov porosity sab hauv ntawm cov khoom yog siab, lub zog ntawm cov khoom yog txo, thiab lub ntuj solidification lub sij hawm ntev dhau lawm, ncua lub sij hawm noj qab haus huv. Ntxiv dej tsawg dhau, cov khoom siv tsis zoo, kev co tsis ntom, yooj yim tawm hauv qhov hws, qhov tsua, thiab lwm yam, lub zog yuav txo qis heev.
2. Kev tswj tsis zoo ntawm lub sijhawm sib xyaw thiab lub sijhawm vibration ntawm castable refractories:
Lub sijhawm sib xyaw yog luv dhau, cov khoom siv tsis sib xyaw sib xyaw, tsis ntom, thiab lub zog txo qis. Cov khoom nchuav yuav tsum siv tamper los ua stratification. Lub sijhawm co lub sijhawm ntev dhau lawm, thiab cov khoom siv tau yooj yim rau stratify. Cov hmoov zoo ntab rau ntawm qhov chaw thiab cov pob zeb ua rau hauv qab, ua rau cov khoom siv kom txo tau lub zog thiab yooj yim poob. Cov khoom yuav tsum tau siv li ntawm 30 feeb ntawm kev sib tov thiab yuav tsum tau muab nchuav rau hauv lub thickness thiab qhov siab ntawm ib zaug. Kev tsim khoom lag luam yuav tsum tau ua nyob rau hauv ib puag ncig saum toj 5 degree, vim tias qhov kub thiab txias tsis dhau, cov khoom siv tsis yooj yim kom qhuav cov khoom, txawm tias cov khoom qhuav, yog qhov tshwm sim tsis tseeb, cov khoom lag luam yuav tsum tau nchuav mus rau hauv thawj txheej. ntawm cov khoom lag luam ua ntej ziab khoom, yuav tsum pov ob txheej ntawm cov khoom. Yog hais tias qhov kev tsim kho clearance tshaj nws qhov chaw pib, nws yuav tsum tau kho raws li qhov yuav tsum tau ntawm kev sib haum xeeb pob qij txha.
3. Kev tswj tsis zoo ntawm lub sijhawm tawm mus ntawm castable refractories:
Pwm cov khoom ua ntej hardening. Yuav tsum nyob rau hauv lub zog ntawm cov khoom lag luam kom ntseeg tau tias nws cov ntug thiab lub kaum sab xis yuav tsis raug puas los ntawm pwm, nws tuaj yeem disassembled. Ua ntej ntxuav cov pwm, tus qauv bearing yuav tsum ncav cuag 70 feem pua lub zog ntawm cov khoom. Txhawm rau txhawb cov pwm, ua ntej casting, tag nrho cov pwm casting nto yuav tsum tau coated nrog ib txheej roj.
4. Tsis muaj qhov tsim nyog tswj lub sijhawm noj qab haus huv ntawm castable refractories:
Tom qab ua tiav ntawm lub boiler, yuav tsum muaj lub sijhawm ziab kom txaus, yog li feem ntau ntawm cov dej hauv txheej hluav taws tuaj yeem sib cais, kom tsis txhob muaj dej ntau hauv qhov cub tsis tuaj yeem tawm hauv lub sijhawm, kom cov refractory. txheej cais thiab poob tawm. Ua ntej qhov cub, cov khoom lag luam muaj lub zog zoo sib xws (lub sijhawm noj qab haus huv txaus) mus txuas ntxiv. Lub hauv paus ntsiab lus ntawm qhov cub yog "qhov nruab nrab ntev yuav tsum tsis txhob luv, nruab nrab qeeb qeeb yuav tsum tsis txhob ceev". Raws li qhov preset qhov cub nkhaus, cov cua kub ceev yuav tsum zoo ib yam thiab ruaj khov, thiab lub sij hawm tswj qhov kub thiab txias yuav tsum tau tswj kom zoo, kom qhov kub thiab txias hloov yuav tsum tsis txhob ntau tshaj ± 20 degree ntawm castable refractories. Tsis txhob kub siab heev, tsis tuaj yeem tso dej tawm hauv lub sijhawm, rhuav tshem cov khaubncaws sab nraud povtseg; Thib ob, nws tuaj yeem tiv thaiv qhov kub thiab txias hauv cov hluav taws kub tiv thaiv txheej yog qhov loj heev thiab ua rau muaj kev ntxhov siab loj heev, kom cov txheej txheem tiv thaiv hluav taws tawg, nthuav tawm thiab poob tawm.
