Ekebere brik aluminom dị elu
Uru ngwaahịa: nrụpụta dị elu na oke ịkpa oke ọkụ, site na mmụba nke ọdịnaya Al2O3, arụmọrụ nguzogide slag ka mma.
Ngwa ngwaahịa: A na -ejikarị ya maka mkpuchi nke ite ọkụ, ọkụ na -enwu ọkụ, ọkụ ọkụ eletrik, ite ọkụ, ite ọkụ na -emegharị, na igwe ọkụ. Tụkwasị na nke ahụ, a na -ejikwa brik aluminom dị elu eme ihe dị ka bricks na -eme ka ọkụ na -agbanwe agbanwe, plọg maka usoro ịwụsa, blọkọ ọnụ, wdg.
nkọwa ngwaahịa
Ntinye brik alumina dị elu na ebe a na -esi nri bụ teknụzụ dị oke mkpa, ọkachasị na mpaghara nwere ihe owuwu dị mgbagwoju anya, nnukwu mgbanwe na curvature na akụkụ arched nke elu ụlọ ọkụ. Ịwụnye brik ndị na-adịghị mma nke ọma nwere ike ibute ọkụ ọkụ ma ọ bụ ịgba ọkụ. Brick refractory brik ga -eweta nnukwu nsogbu na -ewu. Ya mere, ọ dị mkpa ịhazi brik nwere ụdị pụrụ iche nke pụrụ iche, nke nwere ike belata ihe isi ike nke owuwu ma wepụ oghere ndị nwere ike ịdapụta n’ihi nsogbu ụlọ mgbe ị na-eji brik dị elu nke alumina. Ndụ ọkụ ọkụ.
Ogo ogo nke brik alumina dị elu pụrụ iche kwesịrị imezu ihe ndị a:
(1) Ndidi akụkụ: ịdị elu dị elu ± 2%; elu ihu wedge nnukwu na obere isi obosara ndidi ± 2mm; Ndidi nha nha ± 1mm; ogologo ndidi ± 1%. Brik alumina dị elu emere nkeonwe, ihe dị iche bụ 2mm.
(2) Ọnwụ ihu. Kwe ka akụkụ ọkụ ma ọ bụ oyi nwee akụkụ abụọ mebiri ruo 40mm ogologo na omimi 5mm; mana ekweghị ka ọ gafere.
(3) Mfu angular. Enwere naanị otu nkuku mebere brik alumina dị elu nke emere na elu na-ekpo ọkụ na oyi, na ngụkọta ogologo nke akụkụ atọ nke mmebi nkuku ekwesịghị gafere 50mm. A naghị atụle mfu nkuku nke gafere 20mm.
(4) Mgbawa. A na-ekwe ka elu brik nwee ntutu dị ka obere mgbawa; enweghị ihe mgbawa ọ bụla yiri nke a na -eyi; A na -anabata mgbawa ndị ọzọ na -adịghị ogologo karịa 40mm ma ọ bụghị obosara karịa 0.2mm.
(5) Olulu, akara agbaze na mkpọtụ. Olulu a na -ekwe na akara agbazere bụ 10mm n’obosara na 10mm n’ịdị omimi; ọkpụrụkpụ bụ 0.5 mm. Nnukwu brik alumina nwere akụkụ dị iche iche siri ike n’otu brik agaghị agafe 70% nke ngụkọta.
