Akwa aluminom eluigwe na ala brik

Igwe blọk arc dị elu nke aluminom bụ ihe na-agbanwe agbanwe na-anọpụ iche, nke nwere ike iguzogide mbibi nke slag acidic na slag alkaline. N’ihi na o nwere SiO2, ike ya iguzogide slag alkaline esighị ike karịa nke slag acidic. Na mgbakwunye, nguzogide slag nke ngwaahịa alumina dị elu na-emetụtakwa nkwụsi ike nke ngwaahịa dị na slag. N’ikwu okwu n’ozuzu, mgbe ịkpụzi mgbali elu na mgbanyụ ọkụ dị elu, ngwaahịa nwere porosity dị ala nwere nguzogide slag dị elu.

Arc nke brik arc ụwa niile bụ okirikiri okirikiri, njedebe nke ọzọ bụ uzo. N’agbanyeghi oke o nwere, ọ ga -agbanwe ma na -emegharị ahụ. Ebe ọ na -enweghị okporo osisi ma nwee ntakịrị ntụzịaka n’ogo, enwere ike wulite ya na okirikiri. Ihe a na -akpọ arc eluigwe na ala, a na -eji ụdị brik a na ladle. A na -ejikarị brik refractory brik arc elu ụwa niile dị ka ihe mkpuchi nke ịwụ nchara. Ọ na -abụkarị ụrọ. Ugbu a jiri brik alumina dị elu dochie ya. Nnukwu brik arc zuru ụwa ọnụ bụ silicate aluminom nwere ọdịnaya alumina karịa 48%. Quality refractory. Emebere ya ma tinye ya na bauxite ma ọ bụ akụrụngwa ndị ọzọ nwere ọdịnaya alumina dị elu. Nkwụsi ike dị elu dị elu, nrụgharị dị elu karịa 1770 ℃. Nguzogide slag ka mma.

A na -ejikarị brik na -emegharị brik na -emegharị ahụ ka ọ bụrụ mkpuchi nke ladle. Ọ na -abụkarị ụrọ, mana ugbu a, a na -eji brik alumina dị elu dochie ya. Dabere na ọnọdụ ojiji, anyị kwenyere na brik arc ụwa nwere uru ndị a:

1. Ike mkpakọ na nguzogide abrasion na ụlọ okpomọkụ. Ezi nguzogide kemịkal, ọkachasị slag acidic. Oke okpomọkụ creep ọnụego dị ala. Ọmarịcha arụmọrụ mgbochi mgbochi.

2. Njikọ ndị na -ehulata nwere ike ịkwaga n’enweghị ihe ọ bụla ma nwee ike ịlaghachi na azụ ka ịhazigharị okirikiri mgbe a na -edo brik, yabụ ọ dị mma iji wuo brik na -agbanwe agbanwe, na oghere brik nwere ike iru 1 mm. A na -ebelata ọkpụrụkpụ brik na -ekpuchi ya, a na -abawanyekwa ikike nke ịgbà nchara.

3. Ogwe kwụ ọtọ nke brik arc ụwa niile pere mpe, nke bụ 70% na -erughị nkwonkwo kwụ ọtọ nke brik refractory ọkọlọtọ, nke na -ebelata iji apịtị na -agbanwe agbanwe ma na -echekwa ọnụ ahịa ihe. Enwere ike ịhazi nha ya n’ogologo ọ bụla.

3. Ogologo ndụ ọrụ, yana ọtụtụ brik ụrọ klaasị rịrị site na 210%.

4. Site na mbelata oriri ọgwụgwọ otu, ọ na-egosikwa ịdị elu nke arc eluigwe na ala dị elu. Na Mbelata oriri otu nwere ike ịkọwa mbelata kwekọrọ na ntinye nke na-abụghị ọla na nchara nchara.

5. Mgbe ịmaliteghachiri ọrụ, lelee na nguzogide nzere nke ngalaba nke brik alumina dị elu na slag na nchara nchara dị mma karịa nke brik ụrọ multi-clinker.

6. Enwere ike iji brik na -emegharị brik mgbe a na -edo brik n’ihi ịdị okirikiri na nsọtụ abụọ ahụ. Gaa n’ihu na n’ihu ka ịhazigharị okirikiri, yabụ na ọ dị mma iji wuo brik na -agbanwe agbanwe, na oghere brik nwere ike iru 1 mm.

7. Ọdịdị kwụ ọtọ nke blọk arc ụwa niile pere mpe, nke bụ 70% na -erughị nkwonkwo kwụ ọtọ nke brik na -agbanwe agbanwe, nke mere na mmetụta mbuze nke akwa igwe a wụrụ awụ na -agbago na ala na miri n’ime nkwonkwo brik bụ gbazie.

8. N’ihi mmụba nke ịdị mma nke brik na -agbanwe agbanwe, enwere ike ibelata ọkpụrụkpụ nke bricking lining, na ike nke ịgbà nchara na -abawanye n’otu aka ahụ.

9. N’ihi ndụ ogologo oge na ịkpụ blọk dị mma, ọrụ ị na -arụ nkwọ nchara n’azụ ọkụ na -ebelata yana ọnụego ojiji nke mgbọ ígwè na -abawanye.
