Vim yog qhov kev sib hloov ntawm lub tshuab hluav taws xob thaum lub sijhawm ua haujlwm, thiab kev sib txhuam thiab kev ntxhov siab ntawm cov khoom siv phom sij hauv, nws yuav tsum tau ua kom cov refractories cib yuav tsum tau khaws ib qho chaw nthuav dav raws li kev nthuav dav coefficient.refractory brickslawv tus kheej thaum lub sij hawm masonry, thiab sab hauv yuav tsum tiaj tus, du, tsis muaj kauj ruam, thiab tsis zoo. Rau qhov kawg no, nruj me ntsis tswj cov ntsiab lus tseem ceeb ntawm masonry kev tsim kho thiab optimizing lub masonry txoj kev yuav txo tau cov thinning tus nqi ntawm refractory firebricks. Txoj kev optimized masonry muaj xws li:
(1) Center point calibration: Siv ib theem thiab ib tug plumb bob los nrhiav 3 ntsiab lus kom paub meej tias 2 axial center kab ntawm lub tog raj kheej, thiab nyob rau tib lub sij hawm nrhiav 5 circumferential siv kab thiab roundness calibrate qhov nruab nrab ntawm lub tog raj kheej. Masonry raws li qhov nruab nrab ntawm lub tog raj kheej tuaj yeem kuaj xyuas qhov deformation ntawm lub tog raj kheej thiab xyuas kom meej tias qhov sib txawv ntawm qhov sib txawv ntawm cov hluav taws kub cib tsis sib xws thaum lub sij hawm masonry.
(2) Xaiv cov qauv masonry: Thaum lub sij hawm masonry, kab rov tav cib pob qij txha yog staggered los ntawm axial staggered masonry txoj kev, uas zoo txo qhov sib xws ntawm tus txheeb ze zawv zawg ntawm txhua lub nplhaib ntawm refractory bricks, txo lub zos kev nyuaj siab ntawm refractories bricks, thiab thiaj li. qhov tshwm sim ntawm cib kaum kev puas tsuaj. Tsis txhob xaiv cov txheej txheem ntawm cov mortar tsis txaus nyob rau hauv masonry, vim hais tias txoj kev masonry yuav ua rau lub cib pob qij txha yuav tsum zoo ib yam thiab nws yooj yim rau bending, uas yuav ua rau lub zos kev nyuaj siab ntawm hluav taws kub bricks yuav loj thaum lawv swb txheeb ze rau ib leeg, thiab nce qhov tshwm sim ntawm kev puas tsuaj rau lub zos ces kaum ntawm lub refractories bricks.
(3) Reserve expansion pob qij txha: Txawm hais tias refractory hluav taws cib yog ib yam ntawm cov khoom zoo li refractory sintered ntawm qhov kub thiab txias, lawv tseem yuav nthuav mus rau qee yam vim yog cua sov hauv kev tsim khoom thiab kev ua haujlwm tiag tiag; Thaum lub sij hawm masonry txheej txheem ntawm "tshem tawm chaw", ib tug 5 hli expansion sib koom ua ke yog teem nyob rau hauv lub circumferential kev taw qhia ntawm txog 1 meter rau txhua txhua 5 rings ntawm refractories cib kom tso lub thermal expansion ntawm refractory hluav taws cib, yog li txo qhov extrusion thiab tawg ntawm refractory. hluav taws kub.
(4) Nws yog nruj me ntsis txwv tsis pub siv rauj rau bricklaying: Refractory cib raug rho tawm haujlwm ntawm qhov kub thiab txias. Txawm hais tias lawv nyuaj, lawv tseem nkig thiab tsis tuaj yeem tiv taus qhov cuam tshuam ntawm cov ntaub ntawv nruj. Lawv yuav tsum tau muab tso nrog cov cuab yeej hloov tau xws li ntoo hammers thiab roj hmab hammers. Yog hais tias nws yog tsim nyog los siv ib tug rauj rau bricklaying, nws yog tsim nyog los cushion nws nrog ntoo boards kom tsis txhob muaj kev sib cuag ncaj qha nrog refractory hluav taws cib thiab ua kom puas.
(5) Xauv cib:
ib. Refractories cib masonry yog nqa tawm nyob rau hauv rings. Txoj hauj lwm masonry yuav tsum ua kom tiav nyob rau tib hnub. Tag nrho lub nplhaib ntawm cib xauv thiab ua haujlwm tiav yuav tsum tsis txhob cuam tshuam rau hauv nruab nrab, txwv tsis pub cov av nkos yuav raug nyem vim lub sijhawm coagulation tsis sib haum.
b. Nyob rau hauv qhov tseeb masonry ntawm hluav taws cib nrog tsim qhov ntev, vim lub thickness sib txawv ntawm refractory mortar thiab qhov tso cai sib txawv me me ntawm refractory hluav taws cib, nws yog ib qhov tsim nyog los siv cov txheej txheem cib rau qhov kawg ntawm lub masonry. Feem ntau, qhov kev kwv yees pib los ntawm txoj hauj lwm ntawm peb mus rau tsib refractory firebricks mus nrhiav qhov tsim nyog loj ntawm lub xeem refractories cib.
c. Thaum siv cov cib ua tiav rau kev xauv cov cib, thaum qhov ua tiav loj dua 50% ntawm qhov loj me, cov qauv cib qub yuav hloov thiab cuam tshuam rau nws lub zog tiag tiag. Nws kuj tseem tuaj yeem tawg tau tom qab raug rau lub zog loj thaum lub sij hawm tig ntawm lub tshuab hluav taws xob thiab tsis tuaj yeem tiv taus lub siab, uas yuav cuam tshuam rau kev ncaj ncees ntawm cov refractory bricks thiab ua rau muaj kev nyab xeeb xws li poob los yog tawg. Yog li ntawd, feem ntau yuav tsum tsis pub ntau tshaj 2 cov txheej txheem refractories cib yuav tsum tshwm sim hauv txhua lub voj voog ntawm cov cib; Qhov ntev ntawm cov txheej txheem refractory firebricks yuav tsum tsis pub tsawg tshaj 50% ntawm cov thawj refractory firebricks, thiab lub thickness yuav tsum tsis txhob tsawg tshaj li 80% ntawm cov thawj refractory firebricks; Yog tias yuav tsum tau 2 lub cib ua tiav, lawv yuav tsum tau muab tso rau ntawm ob sab ntawm ib lossis ob lub cib tag nrho, thiab 2 cov txheej txheem cib tsis tuaj yeem muab tso rau ib leeg. Qhov kawg xauv cib ntawm tag nrho cov kiln yuav tsum tau ua kom zoo, thiab nws yog nruj me ntsis txwv tsis pub kaw lub cib nrog castables ib leeg, tab sis lub xeem xauv cib tuaj yeem kho nrog castables. Lub locking bricks yuav tsum ruaj thiab yuav tsum tsis txhob muab misplaced.
Los ntawm optimizing lub refractory cib nteg txheej txheem thiab txoj kev, qhov zoo ntawm hluav taws cib nteg nyob rau hauv lub teb kiln yog zoo dua, thiab kev khiav hauj lwm efficiency ntawm hluav taws cib yog zoo dua. Thaum lub sij hawm masonry txheej txheem, tsuas yog tsim nyog refractory firebricks yog nruj me ntsis siv, thiab nws yog nruj me ntsis txwv tsis pub siv cov cib tsis zoo nrog cov ces kaum tawg los yog tawg. Txhawm rau kom tsis txhob muaj kev puas tsuaj ntawm cov khib nyiab pov tseg ntawm qhov khoob ntawm cov hluav taws kub refractory cib, cov paj masonry yog xaiv los tsim cov khib nyiab khib nyiab pov tseg, thiab cov roj hmab hammers yog siv rau hauv cov masonry los txo qhov nyuaj ntawm cov hluav taws kub; expansion pob qij txha yog tshwj tseg raws li lub thermal expansion ntawm lub refractories bricks lawv tus kheej kom zoo zam lub refractory bricks los ntawm tawg los ntawm lub zog quab yuam; Kev ntsuas tau raug coj los ntsuas thaum ntsuas cov cib kom paub meej tias qhov loj ntawm qhov kawg ua tiav cib tsim nyog kom tsis txhob nce lub siab ntawm lub voj voog vim qhov loj thiab ua rau lub voj voog xoob vim qhov me me, uas cuam tshuam rau tag nrho cov qauv ntawm cov masonry.
