Uru arụmọrụ nke Bricks Carbon Magnesia

Uru nke brik carbon magnesia bụ:iguzogide slag ozize na ezigbo thermal ujo iguzogide. N'oge gara aga, mwepu nke brik MgO-Cr2O3 na brik dolomite bụ na ha na-etinye akụkụ slag, na-ebute spalling nhazi, na-eduga na mmebi oge. Site n'ịgbakwunye graphite, brik carbon magnesia kpochapụrụ adịghị ike a. Ihe e ji mara ya bụ na slag na-abanye naanị n'ime elu na-arụ ọrụ, ya mere oyi akwa mmeghachi omume Ejidebere n'elu ọrụ, usoro ahụ nwere obere peeling na ogologo ndụ ọrụ.

Ugbu a, na mgbakwunye na asphalt ọdịnala na brik carbon magnesia nke resin (gụnyere brik magnesia gbanyere mmanụ ọkụ),brik carbon magnesia a na-ere n'ahịa gụnyere:

(1) Magnesia carbon brik mere nke magnesia nwere 96% ~ 97% MgO na graphite 94% ~ 95% C;

(2) Magnesia carbon brik mere nke magnesia nwere 97.5% ~ 98.5% MgO na graphite 96% ~ 97% C;

(3) brik carbon Magnesia mere nke magnesia nwere 98.5% ~ 99% MgO na 98% ~ C graphite.

Dabere na ọdịnaya carbon, a na-ekewa brik carbon magnesia n'ime:

(I) brik magnesia nke etinyere mmanụ na-agba ọkụ (ihe nwere carbon na-erughị 2%);

(2) brik magnesia jikọtara carbon (ọdịnaya carbon na-erughị 7%);

(3) sịntetik resin bonded magnesia carbon brik (ọdịnaya carbon bụ 8% ~ 20%, ruo 25% n'ọnọdụ ole na ole). A na-agbakwunyekarị antioxidants na asphalt/resin bonded magnesia carbon brik (ọdịnaya carbon bụ 8% ruo 20%).

A na-emepụta brik carbon Magnesia site na ijikọta ájá MgO dị elu dị ọcha na graphite scaly, carbon black, wdg. Usoro mmepụta ihe na-agụnye usoro ndị a: nchikota akụrụngwa, nyocha, grading, ịgwakọta dị ka usoro ihe onwunwe si dị na nhazi nhazi ngwaahịa, dịka si The Nchikota A na-ebuli ọnọdụ okpomọkụ nke ụdị gị nso nso 100 ~ 200 ℃, a na-ejikọta ya na ihe nkedo iji nweta ihe a na-akpọ MgO-C apịtị (ngwakọta ahụ na-acha akwụkwọ ndụ akwụkwọ ndụ). Ihe apịtị MgO-C na-eji resin sịntetik (karịsịa resin phenolic) na-akpụzi na ọnọdụ oyi; ihe MgO-C apịtị jikọtara ya na asphalt (na-ekpo ọkụ na ọnọdụ mmiri) na-akpụzi na ọnọdụ dị ọkụ (ihe dịka 100 Celsius) na-etolite. Dị ka ogbe nha na arụmọrụ chọrọ nke ngwaahịa MgO-C, akụrụngwa na-eme mkpọtụ, akụrụngwa na-akpụzi mkpakọ, ndị extruders, presses isostatic, igwe na-ekpo ọkụ, akụrụngwa kpo oku, na akụrụngwa ramming nwere ike iji hazie ihe apịtị MgO-C. ka ezigbo udi. A na-etinye ahụ MgO-C a kpụrụ akpụ na kiln na 700 ~ 1200 Celsius maka ọgwụgwọ okpomọkụ iji gbanwee ihe na-ejikọta ya na carbon (a na-akpọ usoro a carbonization). Iji mee ka njupụta nke brik carbon magnesia dịkwuo elu ma mee ka njikọ ahụ sie ike, a pụkwara iji ihe ndị yiri ihe nkedo mee ihe iji mee brik ahụ.

N'oge a, a na-ejikarị resin sịntetik (karịsịa resin phenolic) dị ka ihe na-ejikọta brik carbon magnesia.Ojiji nke sịntetik resin bonded magnesia carbon brik nwere uru ndị a bụ isi:

(1) Akụkụ gburugburu ebe obibi na-enye ohere nhazi na mmepụta ngwaahịa ndị a;

(2) Usoro nke ịmepụta ngwaahịa n'okpuru ọnọdụ ngwakọta oyi na-azọpụta ike;

(3) Enwere ike ịhazi ngwaahịa ahụ n'okpuru ọnọdụ anaghị agwọ ọrịa;

(4) N'iji ya tụnyere tar asphalt binder, ọ dịghị ihe na-emepụta plastik;

(5) Mmụba carbon ọdịnaya (karịa graphite ma ọ bụ bituminous coal) nwere ike melite eyi nguzogide na slag iguzogide.
