Noble hlau roasting rauv rauv refractory kev tsim kho thiab masonry yuav tsum

Cov txheej txheem ntawm lub qhov cub masonry thiab cov kev cai ntawm cov hlau muaj nuj nqis ore roasting rauv yog sib sau ua ke thiab sib sau ua ke los ntawm refractory cib chaw tsim tshuaj paus.

Lub tshuab hluav taws xob ntawm cov khoom siv hluav taws xob muaj txiaj ntsig zoo muaj lub voj voog, suav nrog tsib ntu: hauv ob sab phlu, sab hauv sab hauv lub tshuab hluav taws xob hauv ob sab phlu, lub khob hliav qab rauv phab ntsa hauv ob sab phlu, sab sauv ncaj ncaj rauv phab ntsa hauv ob sab phlu, thiab lub tshuab hluav taws xob hauv ob sab phlu.

1. Tej yam kev mob rau roasting rauv siv:

(1) Lub plhaub ntawm lub cub tawg ntawm lub cub tawg tau raug ntsia thiab dhau qhov kev tshuaj xyuas.

(2) Qhov kub ntawm qhov chaw tsim kho yuav tsum tsis txhob qis dua 5 ° C, thiab yog tias nws qis dua 5 ° C, nws yuav tsum tau kho raws li lub caij ntuj no kev tsim kho.

(3) nruj me ntsis tswj cov hom, kom muaj nuj nqis thiab zoo ntawm cov ntaub ntawv refractory uas tau nkag mus rau hauv lub site kom ntseeg tau tias lawv ua tau raws li cov qauv tsim thiab kev tsim kho thiab tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm lub sijhawm tsim kho.

2. Cov txheej txheem kev tsim kho ntawm lub cub tawg thiab qhov yuav tsum tau ua:

(1) Kev tsim kho txheej txheem:

Lub tshuab hluav taws xob txais tos thiab teeb tsa kev ua haujlwm → kev teeb tsa ntawm scaffolding thiab nqa ncej → graphite hmoov dej iav los tiv thaiv corrosion txheej rau ntawm phab ntsa sab hauv ntawm lub cub tawg, asbestos rwb thaiv tsev → cub tawg ua hauj lwm txheej, rwb thaiv tsev txheej lub teeb thiab hnyav refractory cib masonry → Rauv lub ru tsev refractory cib masonry → Tshem lub lifting ncej → Tshem lub scaffolding → Distribution phaj refractory castable castable tsim thiab txij nkawm → ntxuav ntawm qhov chaw tsim kho thiab ua tiav thiab xa.

(2) Kev ntsuas kev tsim kho:

1) Scaffolding installation:

Sab hauv scaffold rau hauv ob sab phlu ntawm lub cub tawg siv fastener-hom steel yeeb nkab scaffolds los muab kev tsim kho cov neeg ua haujlwm nrog taug kev thiab tsim kho lub hom phiaj. Yog li ntawd, nws yuav tsum tau ua raws li cov qauv tsim kom ntseeg tau tias nws ruaj khov thiab ruaj khov.

2) Kev thauj mus los ntawm cov khoom siv refractory:

Kab rov tav kev thauj mus los: Cov khoom siv refractory nyob rau hauv qhov chaw tsim kho feem ntau yog thauj los ntawm cov tsheb thauj khoom, ntxiv los ntawm kev tuav tuav, thiab cov neeg ua haujlwm tsim kho thiab cov khoom siv refractory tuaj yeem nkag mus thiab tawm ntawm lub qhov cub plhaub manhole.

Kev thauj mus los ntsug: Siv cov lifting ncej tsim sab hauv thiab sab nraum lub qhov cub kom txav cov khoom siv refractory thiab cov neeg ua haujlwm tsim kho nce thiab nqis.

3) Kev tsim cov log tsheb thiab cov qauv:

Rauv manholes thiab lwm yam arched masonry yuav tsum tau arch log tsheb thiab casting cov ntaub ntawv uas yuav tsum tau rau kev tsim kho yuav tsum tau ua kom tiav ntawm qhov chaw raws li yuav tsum tau.

4) Kev tshuaj ntsuam refractory cib:

Tom qab tag nrho cov refractory cib nkag mus rau hauv qhov chaw, lawv raug cais raws li cov ntaub ntawv sib txawv thiab cov lus qhia tshwj xeeb thiab khaws cia kom zoo. Cov cib refractory nrog cov ces kaum loj heev, tawg, khoov thiab lwm yam tsis xws luag raug xaiv thiab siv tsis tau rau masonry. Lawv tuaj yeem khaws cia rau kev ua cov cib. .

5) Pre-ntev thiab ua refractory bricks:

Txhawm rau ua kom cov txheej txheem tsim kho, cov cib refractory ntawm lub vault thiab txhua lub qhov feem ntau yog ua ntej ua ntej txiav txim rau kev ua thiab kev siv cov refractory bricks. Nws tseem tuaj yeem tshawb xyuas seb qhov kev txhawb nqa kev tsim kho puas ruaj khov thiab txhim khu kev qha, thiab seb cov cuab yeej abrasive puas tsim thiab xav tau. Cov teeb meem kev tsim kho tau tshawb pom thiab daws tau ua ntej los ntawm kev ua ntej masonry, kom cov neeg ua haujlwm tsim kho tuaj yeem nkag siab zoo txog kev txiav txim siab masonry, cov kev xav tau zoo thiab siv cov khoom siv refractory.

a. Lub pre-masonry ntawm lub masonry yog tib yam li formal masonry, qhov txawv yog hais tias cov ntub masonry yog hloov mus rau qhuav pre-ntev, thiab expansion sib koom ua ke yuav tsum tau raws li tus tsim thiab kev tsim kho.

b. Lub prefabrication ntawm lub vault bricks yuav tsum tau nqa tawm nyob rau hauv lub hauv av raws li ib tug tej yam kev mob raws li qhov tseeb tej yam kev mob, thiab lub prefabrication ntawm txhua lub qhov yuav nqa tawm nyob rau hauv lub tsev los yog nyob rau hauv lub hauv av ntawm qhov chaw tsim kho.

c. Lub qhov masonry masonry siv tshwj xeeb-puab refractory cib. Thaum ua ntej masonry, masonry refractory cib masonry yuam kev loj yuav tsum tau nruj me ntsis tswj raws li tus tsim yuav tsum tau. Thaum qhov kev ua yuam kev loj dhau los ua kom tau raws li qhov yuav tsum tau ua ntawm masonry, cov refractory bricks yuav tsum tau ua kom paub tseeb tias qhov zoo ntawm masonry tsim raws li qhov yuav tsum tau ntawm kev tsim kho.

d. Tom qab ua ntej masonry ntawm lub qhov thiab vault refractory bricks tiav thiab kev soj ntsuam yog lawm, lub refractory bricks yog suav thiab cim, thiaj li hais tias cov formal masonry yuav nqa tawm kom raug thiab smoothly.

6) Lub tshuab hluav taws xob kuaj xyuas, kev lees paub thiab kev teeb tsa:

Tom qab lub plhaub ntawm lub cub tawg tau teeb tsa thiab dhau qhov kev lees paub, rub tawm cov kab nruab nrab ntawm lub tshuab hluav taws xob lub cev, thiab rov ntsuas qhov ovality ntawm lub plhaub ntawm lub cub tawg thiab qhov siab ntawm cov masonry ntawm txhua qhov. Txheej qhov siab kab yog cim.
