Yuav ua li cas los tsim cov yas refractory kom ua tiav xoom expansion?
Refractory plasticsyog ib qho yooj yim thiab ceev los tsim thiab ruaj khov siv. Yog tias koj xav kom cov yas ua tiav xoom nthuav dav, koj yuav tsum tau txais kev tsim xoom-expansion kom offset expansion thiab contraction ntawm cov yas ntawm qhov kub thiab txias.
1. Yas muaj qee yam plasticity thaum kub siab
Refractory plastics muaj qee yam plasticity thaum kub siab. Zero expansion ntawm plastics txhais tau hais tias lawv tuaj yeem tiv taus qhov kev hloov pauv loj hauv qhov cub kub thiab tiv thaiv lub tshuab hluav taws xob ntau zaus thiab kub nce. Cov pwm yas tuaj yeem raug tshem tawm tam sim tom qab kev tsim kho. Yog tias nws yog rau kev saib xyuas, tsis xav tau qhov cub. Nws tuaj yeem muab tso rau hauv kev siv ncaj qha thaum lub qhov cub kub kub nce.
Txawm li cas los xij, thaum lub sij hawm tsim kho, kev saib xyuas yuav tsum tau them nyiaj rau kev tsim kho kom ntseeg tau tias qhov deformation ntawm cov qauv hlau thiab cov hauv ob sab phlu yog synchronized. Tsis tas li ntawd, cov thauj tog rau nkoj cib yuav tsum sib npaug zos kom tsis txhob tawg thiab lub ru tsev tawg thaum siv.
2. Zero expansion tsim yog cov lus piav qhia ntawm kev tsim kho
Kev tsim xoom-expansion txhais tau hais tias thaum lub sij hawm tsim kho, cov pwm yuav tsum tau teeb tsa ua ntej kom ntseeg tau tias thaj chaw tsim kho kom huv si, thiab tom qab ntawd cov yas refractory yuav tsum tau muab tso rau ntawm qhov chaw ramming. Tsuas yog ib txheej ntawm cov khoom tuaj yeem muab tso rau ntawm ib lub sijhawm. Lub taub hau rauj yog downward, thiab lub taub hau rauj yog txav thiab sib tshooj rov qab los ua kom cov yas Flat, chav zais cia. Yog hais tias lub thauj tog rau nkoj bricks tau tsim, tamping nto ntawm cov yas refractory yuav tsum yog 16 mus rau 20mm siab tshaj qhov chaw hauv qab ntawm lub thauj tog rau nkoj cib. Muab cov ntoo pwm tso rau ntawm cov pob zeb thauj tog rau nkoj kom ncaj nws thiab rauj tawm ntawm cov hniav. Cov yas nyob ib ncig ntawm lub thauj tog rau nkoj cib yuav tsum tau pounded nruj nreem.
Kev tsim kho ntawm cov yas refractory yuav tsum tau nteg tawm thiab pounded txheej los ntawm txheej. Txhua txheej yuav tsum tau shaved thiab khaws cia ntawm qhov siab tib yam li qhov chaw tsim kho. Yog hais tias muaj ib ntus thaum lub sij hawm pounding ntawm plastics, cov ntawv yas yuav tsum tau siv los npog cov pounded nto. Qhov saum npoo ntawm cov khoom yuav tsum tau shaved thaum lub sij hawm tsim kho thaum lub caij ntuj nag. Thaum kev tsim kho raug cuam tshuam rau lub sijhawm ntev, kev sib koom ua ke yuav tsum tau sab laug ntawm ob kab ntawm thauj tog rau nkoj cib.
3. Kev piav qhia ntawm cov yas siv rau ntawm qhov cub
Yog tias cov yas refractory siv rau ntawm lub qhov cub sab saum toj, qhov kev coj ntawm lub taub hau rauj yuav tsum yog kab rov tav thaum lub sij hawm ramming, thiab cov pob qij txha ntawm cov khoom nto thiab qhov chaw ua hauj lwm ntawm lub qhov cub sab saum toj yuav tsum yog ntsug. Cov txheej txheej txheej yuav tsum tsis txhob sib tshooj nrog cov pob qij txha ntawm cov khoom nto thaum lub sij hawm tsim khoom; plastics Nyob rau sab saum toj ntawm lub cub tawg, pib pounding los ntawm cov pob qij txha ntawm lub billet; Thaum lub sij hawm tsim kho, txiav cov khoom vertically rau hauv lub cub tawg ntawm lub kaum sab xis thiab npog nws nrog cov ntawv yas kom tsis txhob poob dej. Siv tib cov hniav zoo li no ua ntej anchoring cib los yog dai cib. Cov ntoo pwm bricks yog fastened thiab yas yog tsav mus rau hauv lawv. Tom qab cov hniav raug tsim, cov thauj tog rau nkoj cib yog embedded thiab fastened.
Txawm li cas los xij, cov formwork yuav tsum tau muab tshem tawm sai li sai tau tom qab kev tsim kho yas kom tso cai rau cov dej ntws tawm. Thaum txiav, maj mam txhuam cov yas nyob ib ncig ntawm lub ntsej muag kawg ntawm lub thauj tog rau nkoj cib nrog ib tug ntoo rauj los yog rauj taub hau kom nws haum nruj. Trimming muaj xws li shaving, xuas nrig ntaus qhov cua los yog txiav expansion pob qij txha.
Thaum lub sij hawm tsim kho, cov yas refractory yuav tsum tsis txhob sib cuag nrog dej; Thaum tsim castables nyob rau hauv kev sib cuag nrog refractories plastics, refractory plastics yuav tsum tau waterproofed; lub formwork yuav tsum tau muab tshem tawm sai li sai tau ua ntej lub qhov cub kom cov masonry kom qhuav lawm.
Vim qhov "zero-expansion" tsim ntawm refractory plastics, cov kab nrib pleb thiab nthuav dav ntawm cov masonry tom qab ziab thiab qhov cub tau ntim nrog cov fibers refractory los tiv thaiv lub qhov cub hauv ob sab phlu los ntawm kev ntes hluav taws thiab haus luam yeeb ntawm qhov kub thiab txias. Cov kab nrib pleb thiab cov pob qij txha nthuav dav yuav kaw nyob ib ncig ntawm 1350 degree.
