Nrhiav kev daws teeb meem refractory txhim khu kev qha rau cov chaw ua haujlwm kub siab?SK34 cov cib hluav tawsyog cov kev xaiv ntseeg siab rau metallurgy, iav tsim, ceramics, thiab lwm yam. Tsim los nrog cov tshuaj lom neeg meej thiab kev ua haujlwm thermal zoo dua, cov cib no muab kev ruaj khov thiab kev ua haujlwm zoo, ua lub hauv paus rau cov cub tawg thiab cov cub tawg ua haujlwm siab thoob ntiaj teb.
1. Cov yam ntxwv tseem ceeb ntawm SK34 Firebricks
Cov cib hluav taws SK34 sawv tawm rau lawv qhov kev ruaj khov thermal, lub zog kho tshuab, thiab kev tiv thaiv corrosion, uas tau los ntawm kev tsim khoom siab heev thiab kev sib xyaw ua ke ntawm cov khoom siv. Cov yam ntxwv tseem ceeb suav nrog:
- Kev kam rau siab kub heev:Ntsuas SK34 (1710–1750 ° C refractoriness) nrog 1350 ° C refractoriness nyob rau hauv load (RUL) ntawm 0.2 MPa, lawv ua tau zoo hauv kev ua haujlwm kub nruab nrab mus rau siab yam tsis muaj softening lossis deformation, qhov tseem ceeb rau kev ua kom sov tas li.
- Kev Pleev Xim Tshuaj Zoo Tshaj Plaws:Muaj 34–42% alumina (Al₂O₃) thiab <2.5% ferric oxide (Fe₂O₃), lawv tiv taus kev yaig ntawm cov kua qaub thiab txo qis kev puas tsuaj ntsig txog cov khoom tsis huv, ua rau lub neej ua haujlwm ntev dua hauv cov chaw ua haujlwm hnyav.
- Cov Qauv Muaj Zog & Ntom:Nrog rau qhov ceev ntawm 2.15–2.20 g/cm³ thiab lub zog tsoo txias ≥30 MPa, lawv tiv taus kev puas tsuaj thiab kev cuam tshuam. Qhov porosity qis (19–23%) txo qhov poob cua sov thiab tiv thaiv cov khoom yaj nkag mus, khaws cia kev ruaj khov ntawm cov qauv.
- Kev Ruaj Ntseg Zoo heev ntawm Thermal Shock:Lawv muaj 0.6% linear expansion ntawm 1000°C thiab ±0.3% linear change tas mus li ntawm 1350°C (2 teev), lawv nyiaj tau qhov kub hloov pauv sai yam tsis muaj kev tawg lossis tawg, txo kev txij nkawm thiab lub sijhawm tsis ua haujlwm.
- Kev Loj Hloov Tau Yooj Yim:Muaj nyob rau hauv qhov loj me tus qauv (230 × 115 × 25 mm, 230 × 115 × 75 mm) thiab cov duab tshwj xeeb (arch, corbel bricks), lawv haum rau ob qho tib si cov khoom siv cua sov tus qauv thiab tshwj xeeb, txhim kho kev siv tau yooj yim.
2. Cov Ntawv Thov Kev Lag Luam Tseem Ceeb
Kev ua tau zoo sib npaug ntawm SK34 firebricks ua rau lawv tsis tseem ceeb rau txhua qhov chaw tseem ceeb:
Kev Ua Hlau:Lawv muab cov cub hluav taws xob arc, cov cub hluav taws xob induction, cov ladles, thiab cov cub hluav taws xob rov ua kom sov hauv kev tsim hlau/hlau, tiv taus cov hlau yaj thiab slag erosion, ua kom cov txheej txheem smelting ruaj khov.
Iav & Khoom Siv Ua Los Ntawm Av nplaum:Zoo tagnrho rau cov cub tawg iav thiab cov cub tawg ceramic, lawv qhov kub siab thiab kev ruaj khov thermal tswj tau qhov cua sov sib xws, qhov tseem ceeb rau cov khoom zoo hauv kev tsim iav thiab ceramic sintering.
Lub zog tshuaj lom neeg thiab cua sov:Siv rau hauv cov ntaub thaiv tshuaj lom neeg, cov chaw hlawv khib nyiab, thiab cov chav hlawv boiler, lawv tiv taus cov pa roj corrosive thiab qhov kub siab, ua kom muaj kev nyab xeeb thiab ua haujlwm tau zoo.
Lwm Cov Chaw:Kuj siv rau hauv cov foundry cupolas, brick kilns, thiab industrial cua sov systems, hloov kho rau ntau yam kev xav tau ntawm kev lag luam kub siab.
Xaiv SK34 firebricks rau kev ua tau zoo hauv qhov kub heev. Peb cov khoom ua tau raws li cov qauv zoo thoob ntiaj teb, nrog cov kev daws teeb meem uas hloov kho tau raws li koj cov kev xav tau tshwj xeeb. Tiv tauj peb hnub no kom paub seb SK34 firebricks tuaj yeem txhim kho koj cov khoom siv kom ua haujlwm tau zoo thiab siv tau ntev npaum li cas.
