Kev puas tsuaj rau lub refractory hauv ob sab phlu ntawm teb kiln feem ntau cuam tshuam rau kev txuas ntxiv ntawm kev tsim khoom thiab yog ib qho ntawm cov khoom siv sib tsoo. Qhov ua rau muaj kev sib tsoo muaj xws li cov qauv tsim, cov khoom siv refractory zoo, masonry zoo thiab kev ua haujlwm thiab kev saib xyuas. Los ntawm kev txheeb xyuas tag nrho ntawm ntau yam kev puas tsuaj hauv ob sab phlu, nws yuav pab tau kom nrhiav tau qee qhov laj thawj thiab siv kev tiv thaiv ua ntej kom tsis txhob muaj xwm txheej loj tshaj plaws.
Cov ntaub ntawv ntawm refractories hauv ob sab phlu puas
1. Hom kev puas tsuaj
Lub refractory hauv ob sab phlu ntawm lub qhov cub tawg yog raug rau kev sib xyaw ua ke ntawm cov khoom siv dag zog, kev sib txhuam ntawm cov khoom siv, thermal stress, airflow thiab tshuaj yaig nyob rau hauv lub xeev kev sib hloov mus ntev, uas feem ntau ua rau cov teeb meem hauv qab no:
(1) Lub lifting block yog raug rau cov neeg kho tshuab kev sib hloov lub ntiajteb txawj nqus eccentricity nyhuv, kub kub nyhuv thiab pob zeb cuam tshuam kev sib txhuam rau lub sij hawm ntev, uas ua rau lub prefabricated block rau twist, cov khoom refractory poob tawm, lub thickness yuav txo tau, thiab cov khoom siv refractory poob, lub thickness yuav txo tau, thiab lub lifting block yog raug rau lub mechanical rotation gravity eccentricity effect, high temperature effect thiab pob zeb cuam tshuam kev sib txhuam rau lub sij hawm ntev, uas ua rau lub prefabricated block rau twist, cov khoom refractory poob tawm, lub thickness yuav txo tau, thiab lub lifting block yog raug rau lub mechanical rotation gravity eccentricity effect, high temperature effect thiab pob zeb cuam tshuam kev sib txhuam rau lub sij hawm ntev, uas ua rau lub prefabricated block rau twist, cov khoom refractory poob tawm, lub thickness yuav txo tau, thiab cov prefabricated blocks yuav tsum tau ua los ntawm cov khoom siv refractory. refractory bricks puv nruab nrab ntawm cov lifting blocks kom deform thiab poob tawm.
(2) Melting poob ntawm kub kub calcined txheej
(3) Cov cua ntws nrog qhov sib txawv ntawm qhov kub thiab txias hauv lub cev ua rau cov hmoov av sintered rau hauv cov blocks thiab adhered rau saum npoo ntawm cov khoom refractory los ntawm kub sintering. Thaum lub qhov cub lub cev tig, qhov sib cais ntawm lub ntiajteb txawj nqus ua rau cov khoom siv refractory tuaj yeem tev tawm, cov cib hauv ob sab phlu yuav thinner, lub qhov cub lub cev kub nce, thiab cov qauv hlau hloov mus rau qhov sib txawv, txo cov kev pab cuam lub neej ntawm lub qhov cub.
2. Qhov tshwm sim ntawm ntau yam kev puas tsuaj
Lub Tuam Txhab Refractory Technology Company tau ua qhov kev tshawb fawb dav dav ntawm cov ntaub ntawv refractory hauv ob sab phlu tom qab siv thiab xam qhov tshwm sim ntawm qhov kev puas tsuaj loj:
(1) Mechanical stress accounts rau 37%: tshwm sim los ntawm deformation ntawm lub tog raj kheej thiab thermal expansion ntawm cov cib.
(2) Cov tshuaj yaig rau 36%: tshwm sim los ntawm kev yaig ntawm clinker silicates thiab alkali ntsev.
(3) Thermal stress account rau 27%: tshwm sim los ntawm overheating thiab thermal shock.
Nrog rau qhov sib txawv ntawm qhov cub, kev ua haujlwm thiab kev ua haujlwm sib txawv ntawm qhov cub hauv ob sab phlu, cov saum toj no peb yam ua haujlwm sib txawv, uas feem ntau yog nyob ntawm lub xeev deformation ntawm cov nplaim taws, cov khoom siv hluav taws xob thiab lub tog raj kheej lub tog raj kheej thaum lub sijhawm ua haujlwm, kom lub hauv paus yog raug ntau yam kev ntxhov siab.
