Carbon electrodes: Properties na Ngwa

Carbon electrodes na-eji n'ihi na ọnwụ metal ikuku oven. E wezụga iji ha na-emepụta Weld metal wepụrụ ntụpọ nke metal Ibé akwụkwọ bee Rivet ma na-arụ ọzọ arụmọrụ. Carbon electrodes na-mere nke eletriki amorphous carbon. Emechara na ngwaahịa ndị mpempe akwụkwọ-black elu ma na-okirikiri mkpara, obe ngalaba nke nke dịgasị iche n'ebe 6 18 millimeters. Standard ogologo mkpara bụ 25-70 sentimita.

N'ihi na ọnwụ dị iche iche na iche nke metal carbon electrodes mụwo angles. N'ihi ya, n'ihi na nhazi nke ferrous ọla otu njedebe nke mkpanaka hone n'akuku nke banyere 65 degrees. Ịrụ ịgbado ọkụ nke ferrous metal ihe, gụnyere maka hardfacing mepụtara electrode jisie n'akuku nke 30 degrees.

N'oge imewe nke electrodes eji dekstruzii technology ma ọ bụ ịkpụzi na okpomọkụ omume ikwọ. The isi ngwaahịa na-agụnye Coke ma ọ bụ coal, na tinye dị iche iche binders (tar, pitch, wdg). Mgbe ụfọdụ, ndị carbon electrode nkejikotara metal ntụ ntụ ma ọ shavings.

Ngwaahịa na-eji dị iche iche ọrụ. Ha na-eji ịcha ígwè ihe, na-eme n'oghere doped, carbon na ala alloy steels. Ke adianade ha ịkpụ eji ọla kọpa, igwe anaghị ma ọ bụ nwayọọ nchara na ndị ọzọ alloys eji imewe nke metal owuwu na n'ibu injinịa, shipbuilding, ígwè ọrụ.

Ịgbado ọkụ nke carbon electrode abụrụwo a nnọọ elu mma. Ọ tụnyere ndị ọzọ ahụkarị ụdị ịcha ọtụtụ uru. Mgbe n'ịrụ ịgbado ọkụ eji a carbon electrode na-eji carbon, abịakọrọ ikuku ma ọ bụ eletrik, nke na-enye ohere ịrụ ịcha magburu onwe metal mwepụ. Ịgbado ọkụ ọrụ a rụrụ na ojiji nke abịakọrọ ikuku ma ọ bụ electric aak, nke ọ bụghị nanị na-agbaze ígwè ma na-deletes onwe ya site na ikuku iyi.

Nke a na usoro nke ịgbado ọkụ metal ngwaahịa nwere ya e ji mara. Ka ihe atụ, ihe niile na-arụ ọrụ nwere ike rụrụ naanị na a mgbe nile na ugbu a, na aak ogologo kwesịrị ịbụ na nso nke 6-15 millimeters. Na nke a, aak na-amụnyewo nnọọ mfe na nwere a zuru ezu kwụsie ike. Otú ọ dị, aak ga-atụfu kwụsie ike, na electrode ga gbazee na agēsure ya abụghị polarity emee.

Kpụrụ mgbe ịgbado ọkụ ihe na carbon electrodes aak egosipụta elu uche ka ọnọdụ ihu igwe (mmiri ozuzo, magnetik dutyu, gas aga). Ọzọkwa, mgbe ndị na-eme ịgbado ọkụ ọrụ, nke na-eji carbon electrodes, aak ọkọkpọhi obere arụmọrụ tụnyere ot metal mkpara. Otú ọ dị, uru nke carbon mkpara nwere ike agaghi eleda. Ha na-ekwe ịgbado ọkụ nonferrous metal web ihe, ma na-eme surfacing elektroprihvatkah hardmetals na a ugbu a nke 1 Ka nso.
