High Alumina Refractory Cib
High alumina refractory cib. Al₂O₃ cov ntsiab lus tsawg kawg yog 48%, aluminosilicate tsev neeg. Cov khoom siv tseem ceeb yog bauxite. Tsim thiab raug rho tawm haujlwm ntawm qhov kub thiab txias. Refractoriness tshaj 1770 degree.
Cov high alumina refractory cib no muaj cov thermal stability zoo, muaj zog slag kuj, thiab siab kub zog. Cov ntsiab lus alumina siab dua muab kev ua haujlwm zoo dua. Peb qib raws Al₂O₃ feem pua.
Danyang Dingfeng Industrial Rauv Co., Ltd. Yog tias koj yuav mus rau cov lag luam wholesale siab siab alumina refractory cib ua nyob rau hauv Suav teb, txais tos kom tau txais pricelist los ntawm peb lub hoobkas. Tag nrho cov khoom customized yog nrog cov khoom zoo thiab tus nqi qis.
Khoom txhais

Cov high alumina refractory cib no muaj cov thermal stability zoo, muaj zog slag kuj, thiab siab kub zog. Cov ntsiab lus alumina siab dua muab kev ua haujlwm zoo dua. Peb qib raws Al₂O₃ feem pua.
Kev sib xyaw siv bauxite thiab silica xuab zeb. Piv txwv li: kwv yees li 70% alumina, 30% silica xuab zeb, ntxiv rau qee cov hlau oxide ntxiv. Hluav taws kub ntawm 1500℃rau 1600 degree, thiab txias crushing zog hits saum toj no 80 MPa.
Physical thiab Chemical Properties
High alumina refractory bricks muaj lub zog kub zoo. Koj ntsuas nws los ntawm load softening kub thiab siab kub creep. Siab dua Al₂O₃ muab cov lej zoo dua.
Hauv qab 70% Al₂O₃, lub load softening kub nyob ntawm seb ntau npaum li cas mullite theem koj muaj piv rau cov kua theem. Ntau mullite txhais tau tias siab dua load softening kub. Tus nqi thiab qhov xwm txheej ntawm cov kua theem cuam tshuam rau qhov kub thiab txias ua haujlwm ntau heev. Txo impurities nyob rau hauv cov ntaub ntawv raw nce lub load softening kub thiab txhim kho creep kuj.
Cov mis peb siv feem ntau: qib tshwj xeeb bauxite clinker 40% mus rau 45%, bauxite hmoov 45% mus rau 51%, mos av nplaum 7% mus rau 10%, kyanite hmoov 3% mus rau 5%, thiab pulp pov tseg kua 4% mus rau 5%. This mix gives high strength, high bulk density, low firing temperature (1440℃to 1460℃), reasonable cost, and long life.
Nta
Siab refractoriness
Zoo dua li av nplaum cib thiab semi-silica cib. High alumina bricks khiav ntawm 1750℃mus rau 1790 degree.
High load softening kub
High Al₂O₃ thiab cov impurities tsawg txhais tau tias tsawg dua cov iav melting theem. Load softening kub khiav ntawm 1420℃mus rau 1550 degree. Zoo dua li av nplaum cib, tsis zoo li silica cib.
Zoo slag kuj
Ze li nruab nrab. Lawv tiv thaiv ob qho tib si acid thiab yooj yim slags. Cov ntsiab lus SiO₂ muab me ntsis zoo dua rau cov kua qaub slag.
Zoo tshuaj stability
Resistant slag, molten hlau, oxidation, thiab txo. Siab dua Al₂O₃ thiab tsawg impurities ua kom txhua yam zoo dua.
Daim ntawv thov
High alumina refractory bricks nkag mus rau hauv txhua yam kub kub rauv. Blast furnaces, kub moj tej tawg qhov cub, hluav taws xob furnaces, reverberatory furnaces, teb kilns. Kuj siv rau checker bricks, stopper hau, nozzle cib - nyob qhov twg koj xav tau zoo thermal stability thiab corrosion kuj.
