SK32-36 Pālolo ʻEleʻele
Ka wehewehe kikoʻī
ʻO ka hui mineral o nā pōhaku lepo ka nui o kaolinite (Al2O3 · 2SiO2 · 2H2O) a me 6% ~ 7% impurities (potassium, sodium, calcium, titanium, iron oxides). ʻO ke kaʻina hana ahi o nā pōhaku lepo ka mea nui o ka kaolinite decomposing a hana i nā kristal mullite (3Al2O3 · 2SiO2) ma o ka hoʻomau mau ʻana. I ka wā o ke kaʻina hana, ʻo SiO2 a me Al2O3 i loko o nā pōhaku lepo e hana i nā silicates hoʻoheheʻe haʻahaʻa eutectic me nā haumia, e hoʻopuni ana i nā kristal mullite.
Hoʻokaʻawale nui ʻia nā pōhaku lepo refractory i loko o ka pālolo refractory bricks no nā kapuahi pahū, nā pōhaku lepo refractory no nā umu wela wela, a me nā pōhaku lepo refractory nui no nā kiln aniani e like me kā lākou hoʻohana.
ʻO nā pōhaku lepo palolo no nā umu ahi
ʻO nā pōhaku lepo palolo no nā umu ahi he mau pōhaku lepo i hana ʻia me ka pālolo refractory ma ke ʻano he mea maka a hoʻohana ʻia no ke kūkulu ʻana i nā linings o ka umu ahi. Hoʻohana ʻia nā pōhaku lepo palolo no nā kapuahi pahū no ka ʻāʻī, ke kino, ka puʻu ahi, ka lalo o nā linings puʻupuʻu liʻiliʻi a me ke kino o nā kapuahi nui.
Pono ka ikaika refractory kiʻekiʻe i ka mahana o ka lumi a hiki ke pale aku i ka hana lōʻihi a me ke komo ʻana o ka uku; ka liʻiliʻi liʻiliʻi liʻiliʻi ma lalo o ke kiʻekiʻe o ka mahana a me ka hana lōʻihi, kahi kūpono i ka mālama pono ʻana o ka lining; haʻahaʻa ʻike porosity a me Fe:O. ʻO ka haʻahaʻa haʻahaʻa, e hōʻemi ana i ka waiho ʻana o ke kalapona i loko o nā pores, e pale ana i ka hoʻonui ʻana a me ka wehe ʻana i nā pōhaku lepo refractory i ka wā hoʻohana a me ka pōʻino; liʻiliʻi nā mea hoʻoheheʻe haʻahaʻa. ʻOi aku ka maikaʻi o ka hana ʻana o nā pōhaku lepo palolo no nā umu ahi ma mua o nā pōhaku lepo maʻamau. [2]
ʻO nā pōhaku lepo palolo no nā umu ahi wela
Hana ʻia nā pōhaku lepo no nā umu wela wela i ka pālolo refractory a hoʻohana ʻia e kūkulu i ka umu ahi wela. Hoʻohana ʻia nā pōhaku lepo no nā kapuahi wela i nā kapuahi wela, nā keʻena mālama wela a me nā paia pā. Pono nā pōhaku lepo no nā kapuahi wela e loaʻa ai ke kūpaʻa haʻalulu maikaʻi, ka wela hoʻoluʻu haʻahaʻa kiʻekiʻe a me ka kolo liʻiliʻi.
Kina 3) Hoʻokaʻawale ʻia nā pōhaku lepo pālolo no nā umu wela wela i ʻekolu mau papa e like me nā hōʻailona kino a me nā kemika: RN-42, RN-40 a me RN-36. ʻO nā hōʻailona kino a me nā kemika a me nā hoʻomanawanui dimensional penei:
(1) Inā ʻaʻole ʻoi aku ka laulā o ka papa ma mua o 0.25mm, ʻaʻole i kaupalena ʻia ka lōʻihi;
(2) Ke 0.26-0 ka laula māwae o ka papa. 50mm, ʻaʻole ʻoi aku ka lōʻihi ma mua o 30mm;
(3) Ke ʻoi aku ka laulā o ka papa ma mua o 0.50mm, ʻaʻole kūpono ia. [3]
ʻO nā pōhaku lepo palolo nui no nā kiln aniani
ʻO nā pōhaku lepo palolo nui no nā kīʻaha aniani he mau pōhaku lepo palolo me ke kaumaha o ka ʻāpana ʻaʻole i emi iho ma mua o 50kg i hoʻohana ʻia no ke kūkulu ʻana i nā kiln aniani.
