Brik Magnesia

Ntughari alkaline nwere ọdịnaya magnesium oxide karịa 90% na periclase dị ka isi kristal.

1. Nrụgharị nke brik magnesia dị elu dị ka 2000 ℃, na ọnọdụ ịdị nro dị n’okpuru ibu anaghị agbanwe nke ukwuu dabere na ebe mgbaze nke oge njikọ na oge mmiri mmiri na -emepụta na oke okpomọkụ. Na mkpokọta, ibu na-ebido mmalite okpomọkụ nke brik magnesia bụ 1520 ～ 1600 ℃, ebe ịdị ọcha dị elu nke magnesium nwere oke mmalite nro dị nro ruo 1800 ℃.

2. Ibu ịdị nro na -amalite okpomọkụ nke brik magnesia adịghị iche na okpomoku daa. Nke a bụ n’ihi na ihe mejupụtara ngwakọta nke brik magnesia bụ periclase, mana kristal periclase na brik magnesia anaghị eti mkpu kpuchie netwọkụ, mana jikọtara ọnụ. Cement. N’ime brik magnesia nkịtị, a na-ejikarị usoro silicate na-agbaze dị ala dị ka forsterite na magnesite pyroxene dị ka ngwakọta. Ọ bụ ezie na mkpụrụ kristal periclase mejupụtara brik magnesia nwere ebe na -agbaze dị elu, ha na -agbaze n’ihe dị ka 1500 Celsius. Akụkụ silicate dị, yana viscosity nke mmiri mmiri ya pere mpe na oke okpomọkụ. Ya mere, ọ na -egosipụta na oke nrụrụ nrụrụ aka na ndakpọ okpomọkụ nke brik magnesia nkịtị adịghị iche nke ukwuu, mana enwere nnukwu ihe dị iche na nrụgharị. Okpomoku dị nro na-amalite ịdị nro nke brik magnesia dị ọcha nwere ike iru 1800 Celsius, ọkachasị n’ihi na ngwakọta mkpụrụ ọka periclase bụ forsterite ma ọ bụ dicalcium silicate, yana mgbaze na-agbaze nke eutectic nke ya na MgO hibere. , Ike lattice n’etiti kristal buru ibu yana nrụrụ plastik na oke okpomọkụ dị obere, a na -ejikọkwa kristal nke ọma.

3. Ọnụ ịgbatị kwụ n’ahịrị nke brik magnesia na 1000 ～ 1600 ℃ bụ 1.0%～ 2.0%, ọ bụ ihe dịka ma ọ bụ ahịrị. Na ngwaahịa ndị na-emegharị ahụ, nrụrụ ọkụ nke brik magnesia bụ nke abụọ na brik nwere carbon. Ọ na -abawanye na ọnọdụ okpomọkụ. Elu na ala. N’okpuru ọnọdụ mmiri jụrụ oyi 1100 ° C, ọnụ ọgụgụ nke ihe na -ekpo ọkụ nke brik magnesia bụ naanị 1 ruo ugboro abụọ. Brik Magnesium nwere nguzogide siri ike na slags alkaline nwere CaO na ferrite, mana adịghị ike na slags acidic nwere SiO2. Na

4. Ya mere, ọ kwesịghị ịdị na -akpọnye brik silica mgbe a na -eji ya, ọ ga -ekewakwa ya site na brik ndị na -anọpụ iche. N’ụlọ okpomọkụ, brik magnesia na -eduzi dị obere, mana na oke okpomọkụ, enweghị ike ileghara conductivity ya anya. Ọrụ nke brik magnesia dịgasị iche iche n’ihi akụrụngwa dị iche iche, akụrụngwa mmepụta, na usoro teknụzụ ejiri. Na

5. A na-eji brik Magnesia eme ihe na akwa mkpuchi akwa ọkụ, ite ọkụ ferroalloy, igwe ọkụ na-agwakọta, igwe anaghị agba nchara, ihe ọkụkụ lime maka ihe ụlọ, na ihe nrụpụta ihe na ụlọ ọrụ iko n’ihi ezigbo arụmọrụ okpomọkụ ha na nguzogide siri ike na slag alkaline. Ndị na-agbanwe ọkụ na-ekpo ọkụ, igwe ọkụ na-eme ka ọkụ dị ọkụ na ọwara mmiri dị n’ime ụlọ nrụgharị.

6. N’ozuzu, enwere ike kee ya ụzọ abụọ: brik magnesia sintered (nke a makwaara dị ka brik magnesia chụrụ n’ọrụ) na brik magnesia jikọtara ọnụ (nke a makwaara dị ka brik magnesia na -enweghị ọkụ). A na -akpọ brik Magnesia nwere ịdị ọcha dị elu na oke ọkụ na -agba ọkụ, n’ihi na kọntaktị kpọmkwem nke mkpụrụ ọka periclase; brik nke magnesia fused dị ka akụrụngwa a na -akpọ fused brik ejikọtara ọnụ.

7. ngwaahịa alkaline refractory ngwaahịa na periclase dị ka isi kristal adọ. Ngwaahịa ahụ nwere njiri mara oke ike igwe dị elu, ezigbo nguzogide slag, nguzogide mbuze siri ike, yana olu kwụsiri ike na oke okpomọkụ.

8. Brik Magnesia nwere nrụgharị dị elu, nguzogide alkali dị mma, ọnọdụ mmalite dị elu maka ịdị nro n’okpuru ibu, mana nguzogide ujo na -adịghị mma. A na -eji brik magnesia brik mebere ya dị ka akụrụngwa. Mgbe azọpịsịrị ya, kpụkọta ya ọnụ, gwakọta ya na ịkpụ ya, a na -agba ya n’ọkụ dị elu nke 1550 ruo 1600 Celsius. Ọkụ ọkụ nke ngwaahịa dị oke ọcha dị elu karịa 1750 Celsius. A na-akpụ brik magnesia na-abụghị nke a na-etinye site na ịgbakwunye kemịkalụ kemịkal kwesịrị ekwesị na magnesia, wee gwakọta, ịkpụzi, na ihicha.

9. A na-ejikarị ya eme ihe maka ịkpụpụta alkaline oghe ọkụ, ala ọkụ eletrik na mgbidi ọkụ, mkpuchi mkpuchi oxygen, ihe na-anaghị agbaze ọkụ na-enwu enwu, nnukwu ọwara ọkụ dị elu, blọk magnesia na ciment rotary kiln lining, ala ọkụ na ọkụ nke kpo oku. ọkụ Mgbidi, brik checkered na regenerator nke nnukwu ite ọkụ, wdg.

1. Nhazi ọkwa brik magnesia

Na mkpokọta, enwere ike kee ya ụzọ abụọ: bred magnesia (nke a makwaara dị ka brik magnesia chụrụ n’ọrụ) na brik magnesia jikọtara ọnụ (nke a makwaara dị ka brik magnesia na -enweghị ọkụ). A na -akpọ brik Magnesia nwere ịdị ọcha dị elu na oke ọkụ na -agba ọkụ ka ọ bụrụ njikọta brik magnesia kpọmkwem n’ihi kọntaktị kpọmkwem nke mkpụrụ kristal periclase; brik mere nke magnesia fused dị ka akụrụngwa a na -akpọ fused brik ejikọtara ọnụ.

2. Nhazi ọkwa na iji brik magnesia

Bricks Magnesia nwere nrụgharị dị elu, ezigbo nguzogide slag alkaline, ọnọdụ mmalite dị elu maka ịdị nro n’okpuru ibu, mana nguzogide ujo na -adịghị mma. A na -eji brik magnesia brik mebere ya dị ka akụrụngwa. Mgbe azọpịsịrị ya, kpụkọta ya ọnụ, gwakọta ya na ịkpụ ya, a na -agba ya n’ọkụ dị elu nke 1550 ruo 1600 Celsius. Ọkụ ọkụ nke ngwaahịa dị oke ọcha dị elu karịa 1750 Celsius. A na-eme brik magnesia na-abụghị nke a na-etinye site na ịgbakwunye kemịkalụ kemịkalụ kwesịrị ekwesị na magnesia, wee gwakọta, kpụzie, na ihicha.

Nke atọ, iji brik magnesia

A na-eji ya eme ihe maka ịkpụzi alkaline oghe ọkụ, ala ọkụ eletrik na mgbidi, mkpuchi na-adịgide adịgide nke onye na-atụgharị ikuku oxygen, igwe anaghị agba nchara na-enwu enwu, nnukwu ọwara ọkụ dị elu, blọk magnesia na ciment rotary kiln lining, okpuru ọkụ ọkụ na mgbidi ọkụ ọkụ, lelee brik maka onye na -emegharị ite ọkụ, wdg.
