Tom qab ib lub sij hawm khiav, qhov tshwm sim ntawm qhov xaus yog tshwm sim. Hauv qhov xwm txheej hnyav, nws tseem yuav ua rau lub boiler ncaj qha thiab cuam tshuam rau kev ua haujlwm ib txwm muaj. Txhawm rau txuas ntxiv lub neej kev pab cuam ntawm lub boiler, lub ncuav yog siv los kho qhov chaw uas lub boiler hnyav dua, tab sis qhov tshwm sim ntawm cov khoom tawg tuaj yeem tshwm sim tom qab kev tsim kho tiav. Vim li cas thiaj muaj teeb meem li no? Yog tias koj xav daws qhov teeb meem no, koj yuav tsum xub paub qhov ua rau ntawm qhov tawg.
1. Thaum cov castable refractory yog nplawm, cov dej thiab qib tsis tswj tau zoo
Thaum cov dej sib xyaw ua ke, cov dej ntau dhau, uas yooj yim ua rau cov pore sab hauv ntawm cov ntaub ntawv pouring siab, qhov kev siv yog txo, lub ntuj solidification lub sij hawm ntev heev, thiab lub sij hawm txij nkawm yuav nce. . Yog tias cov dej me me dhau lawm, cov kua dej ntawm cov dej tsis zoo, qhov kev vibration tsis ntom, thiab cov pores thiab npuas yog yooj yim tawm, thiab lub zog kuj yuav txo tau zoo heev.
2. Kev tswj tsis raug ntawm kev nplawm thiab kev tsim kho lub sijhawm
Thaum sib tov cov dej, lub sij hawm sib tov yuav tsum nruj me ntsis tswj. Lub sijhawm luv luv, uas yuav ua rau cov khoom sib xyaw ntawm cov khoom sib tov sib xyaw, tsis ntom, thiab lub zog txo. Nyob rau saum npoo, lub aggregate dab dej nyob rau hauv qab, uas ua rau txo qhov kev siv ntawm watering. Cov dej yuav tsum tau siv li ntawm 30 feeb tom qab stirring tas.
3. Kev tswj lub sijhawm kho hniav tsis zoo
Ntawm no yog qhov tso tawm ntawm cov khoom siv refractory castable. Thaum nws tsis yog tag nrho hardened, thaum twg yog qhov tsim nyog tshaj tawm? Thaum qhov kev siv ntawm cov dej tuaj yeem lav tau thiab nws cov npoo thiab cov ces kaum tsis raug puas vim kev puas tsuaj ntawm demarcation, nws tuaj yeem raug tshem tawm. Txhawm rau kom yooj yim rau kev tso tawm ntawm pwm, lub ncuav nto ntawm tag nrho cov pwm ua ntej pouring yuav tsum tau coated nrog ib txheej roj.
4. Lub sij hawm ntawm refractory castable cov ntaub ntawv tsis zoo tswj
Tom qab kev tsim kho tiav lawm, yuav tsum muaj lub sijhawm ziab kom txaus, yog li feem ntau ntawm cov dej hauv cov txheej txheem refractory tuaj yeem raug ua ntej, txhawm rau tiv thaiv kom tsis txhob muaj dej ntau los ntawm kev tso tawm ntau cov dej thaum lub qhov cub, ua rau lub qhov cub tawg. refractory txheej kom tawg thiab poob tawm. Lub hauv paus ntsiab lus ntawm ziab lub qhov cub yuav tsum tau them sai sai rau "yuav tsum ntev lossis luv, nws yuav tsum tsis txhob ceev." Nws yuav tsum tau nqa tawm raws li qhov ntsuas qhov cub ua ntej, qhov cua kub ceev yuav tsum zoo ib yam thiab ruaj khov, tswj lub sijhawm kub thiab txias, thiab ua kom qhov kub thiab txias tsis siab tshaj ± 20 ° C. Txhawm rau tiv thaiv kub ceev, dej tsis tuaj yeem tawm hauv lub sijhawm, tawg los ntawm kev hnav tsis kam thiab txheej refractory; Thib ob, tiv thaiv qhov kub thiab txias hauv cov refractory thiab hnav tsis kam txheej loj heev, ua kom muaj kev ntxhov siab loj heev, thiab ua rau cov tawv nqaij ua rau tawg, nce, thiab poob tawm.
