Ọkpụkpụ Coke Oven Silica Brick
Brick brik siliki kwesịrị ịbụ ihe na -eweghachi acid nke nwere okwute, cristobalite na obere quartz fọdụrụ na iko iko.
1. Ọdịdị silicon dioxide karịrị 93%. Ezi njupụta bụ 2.38g/cm3. Ọ nwere nguzogide acid slag mbuze. Ike elu okpomọkụ dị elu. Ọnọdụ okpomọkụ nke ịdị nro ibu bụ 1620 ~ 1670 ℃. Ọ gaghị agbarụ mgbe ejiri ogologo oge mee ya na oke okpomọkụ. N’ozuzu, enweghị ntụgharị kristal karịa 600 Celsius. Ọnụ ọgụgụ mgbasawanye obere okpomọkụ. Akwa na -eguzogide ujo ujo. N’okpuru 600 ℃, ụdị kristal na -agbanwe karịa, olu na -agbanwe nke ukwuu, na nguzogide ujo na -adịwanye njọ. A na -eji silica eke dị ka akụrụngwa, a na -etinyekwa ego kwesịrị ekwesị nke na -egwupụta ihe iji kwalite mgbanwe nke quartz na ahụ akwụkwọ ndụ akwụkwọ ndụ ka ọ bụrụ phosphorite. Ejiri nwayọ gbanye ọkụ na 1350 ~ 1430 ℃ na ibelata ikuku.
2. A na-ejikarị ya eme ihe maka ụlọ coking na mgbidi nkewa nke ụlọ ọkụ nke ọkụ ọkụ coke, onye na-emegharị ya na ụlọ slag nke ọkụ na-eme ka nchara na-enwu enwu, nnukwu ite ọkụ, ite na-agbaze iko, ihe na-agba ọkụ nke na-ajụ oyi. ihe na seramiiki, wdg na akụkụ ndị ọzọ na-ebu ibu. A na-ejikwa ya maka akụkụ na-ebu oke ibu nke ekwú ọkụ na-ekpo ọkụ na elu ụlọ na-emeghe ọkụ nke acid.
3. Ihe brik silica bụ quartzite dị ka akụrụngwa, na -agbakwunye obere ego nke mineralizer. Mgbe a na -agba ya ọkụ na oke okpomọkụ, ihe mejupụtara ya nwere tridymite, cristobalite na iko etinyere na oke okpomọkụ. Ọdịnaya AiO2 karịrị 93%. N’ime brik siliki a na-ere nke ọma, ọdịnaya tridymite bụ nke kachasị elu, na-aza 50% ruo 80%; cristobalite bụ nke abụọ, na -aza naanị 10% ruo 30%; na ọdịnaya nke quartz na iko iko na -agbanwe n’etiti 5% na 15%.
4. A na -eji ihe quartzite eme brik silica, tinye ya na obere ihe na -egwupụta ihe, wee gbaa ya ọkụ na oke okpomọkụ. Ihe mejupụtara mineral ya bụ tridymite, cristobalite na enyo nwere nnukwu okpomọkụ. Ọdịnaya SiO2 Ya karịrị 93%.
5. Brik siliki bụ ihe na -egbochi ihe acidic, nke nwere nguzogide siri ike na mbibi acidic slag, mana mgbe alkaline slag na -emebi ya nke ọma, oxides dị ka Al2O3 na -emebi ya ngwa ngwa, ma nwee ezigbo nguzogide oxides dịka iCaO, FeO , na Fe2O3. mmekọahụ.
6. Nnukwu mwepu nke ibu bụ nkwụsi ike ujo dị ala na nrụgharị dị ala, n’ozuzu n’etiti 1690-1730 ℃, nke na-egbochi oke ngwa ya.
Silica brik-anụ ahụ Njirimara
1. Nguzogide acid
Brik siliki bụ ihe na -egbochi ihe acid nwere ike iguzogide mbibi acid slag, mana mgbe alkaline slag mebiri ha nke ọma, oxides dị ka AI2O3 na -emebi ha ngwa ngwa, ma nwee ezigbo nguzogide oxides dịka CaO, FeO, na Fe2O3.
2. Mgbasawanye
Igwe ọkụ nke brik silica na -abawanye site na mmụba nke ọnọdụ okpomọkụ na -arụ ọrụ na -enweghị mbelata. N’oge usoro oven, olu brik silica na -abawanye site na mmụba nke okpomọkụ. N’ime usoro ekwenti, mmụba kachasị nke brik silica na -adị n’etiti 100 na 300 ℃, na mmụba tupu 300 ℃ bụ ihe dịka 70% ruo 75% nke ngụkọta mgbasa. Ihe kpatara ya bụ na SiO2 nwere isi mgbanwe ụdị kristal anọ nke 117 ℃, 163 ℃, 180 ~ 270 ℃ na 573 ℃ na usoro oven. N’ime ha, mmụba olu nke cristobalite kpatara bụ nke kachasị n’etiti 180 ~ 270 ℃.
3. Ọnọdụ nrụrụ n’okpuru ibu
Ọdịdị nrụrụ dị elu dị n’okpuru ibu bụ uru nke brik silica. Ọ dị nso na ebe mgbaze nke tridymite na cristobalite, nke dị n’agbata 1640 na 1680 Celsius.
4. Kwụsie ike
Mperi kasịnụ nke brik silica bụ nkwụsi ike dị ọkụ dị ala na nrụgharị dị ala, n’ozuzu n’etiti 1690 na 1730 ° C, nke na -egbochi oke ngwa ha. Isi ihe na -ekpebi nkwụsi ike nke brik silica bụ njupụta, nke bụ otu n’ime ihe ngosi dị mkpa maka ịchọpụta ntụgharị quartz ya. Obere njupụta nke brik silica, ka ntughari wayo zuru oke, yana obere mmụba fọdụrụ n’oge usoro oven.
5. Ihe brik siliki chọrọ nlebara anya
1. Mgbe ọnọdụ ọrụ na -adị ala karịa 600 ~ 700 ℃, olu brik silica na -agbanwe nke ukwuu, arụmọrụ nke iguzogide oyi ngwa ngwa na ọkụ adịghị mma, na nkwụsi ike ọkụ adịghị mma. Ọ bụrụ na igwe ọkụ coke na -arụ ọrụ na ọnọdụ okpomọkụ a ogologo oge, a ga -agbaji ngwa ngwa ngwa ngwa.
2. Ịrụ ọrụ Njirimara anụ ahụ nke brik siliki coke:
(1) Ibu arọ nro dị elu. Bricks Coke oven silica nwere ike iguzogide ibu dị egwu nke ụgbọ ala na -eburu ọkụ n’elu ụlọ ọkụ n’okpuru oke okpomọkụ, enwere ike iji ya ogologo oge na -enweghị nrụrụ;
(2) Igwe ọkụ ọkụ dị elu. A na -eme Coke site n’iche ọkụ n’ime ụlọ coking site na ikpo ọkụ ọkụ na mgbidi nke ụlọ ọkụ, ya mere, brik siliki a na -eji arụ mgbidi nke ụlọ ọkụ kwesịrị inwe ọkụ ọkụ dị elu. N’ọkụ okpomọkụ nke ụlọ ọkụ ọkụ coke, brik silica nwere conductivity thermal dị elu karịa brik ụrọ na brik alumina dị elu. Ọ bụrụ na e jiri ya tụnyere brik siliki coke nkịtị, enwere ike ịbawanye nrụpụta ọkụ nke nnukwu coke oven silica brik site na 10% ruo 20%;
(3) Ezi iguzogide ujo ujo na oke okpomọkụ. N’ihi ịchaji na coking ọkụ ọkụ oge ụfọdụ, ọnọdụ okpomọkụ nke brik silica n’akụkụ abụọ nke mgbidi ụlọ ọkụ ahụ na -agbanwe nke ukwuu. Mgbanwe ọnọdụ okpomọkụ nke ịrụ ọrụ nkịtị agaghị eme ka mgbawa siri ike na pepụ nke brik silica, n’ihi na karịa 600 ℃, blọk silica coke nwere ezigbo nguzogide ujo dị ọkụ;
(4) Mpịakọta kwụsiri ike na oke okpomọkụ. N’ime brik silicon nwere ezigbo ntụgharị kristal, quartz fọdụrụ abụghị ihe karịrị 1%, na mmụba n’oge kpo oku na -etinye uche tupu 600C, mgbe ahụ mmụba ahụ na -ebelata nke ukwuu. N’oge arụ ọrụ nke oven coke, ọnọdụ okpomọkụ anaghị agbada n’okpuru 600 Celsius, na masonry agaghị agbanwe nke ukwuu, na nkwụsi ike na nsụchi nke masonry nwere ike idobe ogologo oge.
