HP Graphite electrode
Nkọwa
Ngwaahịa a na-tumadi etinyere elu ike elecric arc oku dị ka a conductive ihe, na elu ike graphite electrode e mepụtara na elu àgwà akụrụngwa na àgwà na-achịkwa nditịm n'oge mmepụta usoro.Our ngwaahịa meriri ntụkwasị obi nke ọrụ site ezi mma, ọnụahịa ezi uche dị na ya na ọrụ nlebara anya.
Anyị nwere HP graphite electrodes dayameta 100-700mm.
Njirimara
1.High n'ibu ike, ala eletrik na-eguzogide.
2. Nnukwu ịdị ọcha, ịdị elu dị elu, nkwụsi ike kemịkalụ siri ike.
3.High machining ziri ezi, imecha elu dị mma.
4.High iguzogide oxidation na thermal ujo.
5.Anti-oxidation ọgwụgwọ maka ogologo ndụ.
6. Na-eguzogide mgbawa & spalling.
Ọdịmma chọrọ
1.E kwesịrị inwe ihe na-erughị ntụpọ abụọ ma ọ bụ oghere na elu electrode.
2. E kwesịghị inwe mgbawa transverse n'elu electrode.Maka mgbawa ogologo oge, ogologo ya kwesịrị ịbụ ihe na-erughị 5% nke gburugburu electrode na obosara kwesịrị ịbụ 0.3 ruo 1.0 mm.
3. Obosara nke mpaghara ojii na elu electrode kwesịrị ịbụ ihe na-erughị 1/10 nke gburugburu electrode na ogologo ya kwesịrị ịbụ ihe na-erughị 1/3 nke electrode.
