Zvishandiso Zvekushandisa & Kugadzira Maitiro:
RP Electrodes inogadzirwa kubva kuPetroleum-yakanyorwa cake seyakavhenganiswa chigadzirwa, neyepakati-svutugadzike-point coal tar yakashandiswa seyakagadzirwa.
Maitiro ekugadzira kazhinji anosanganisira:
● Calcining of petroleum coke at ~ 1250 ° C
● Kugadzira kuburikidza nekumusoro-kudzvanywa kwekuwedzera kana kuumbwa
● Pakutanga kubheka pa800-900 ° C to Stabilze chimiro
● vacuum pitch kusakwana kuderedza porosity uye kuvandudza oxidation kuramba
● Kudzora kusimbisa kusungwa
● Kufemerwa kusvika pamakumi maviri nemasere kusvika 2800 ° C in aceson kana lwg-mhando machira ekuvandudza magetsi maitiro uye kutendeka kwechimiro
Kutenderera kwese kwekugadzira kunofamba-famba mazuva makumi mana, zvichienderana nezvinobatsira zvirimwa uye kuronga.
Masango ekushandisa:
● Diki kusvika kuEviki-saizi eafs yeCarbon uye Alloy Simbi Kugadzirwa
● Yakanyungudika Arc Mahara yekugadzirwa kweFerrosilicon, metallurical-giredhi silicon, uye yero phosphorous
● Kuwanikwa uye kukanda mabasa uko kunodzikira lectrode yekushandisa haisi yekutanga kunetseka
● Metallurgical maitiro ane mwero mwero zvazvino uye zvinowanzoitika zvinodiwa
Kubata & Kuchengetedza Kurudziro:
●Chengetedzo yakaoma:Chengetedza mune yakanyorova-yemahara, tembiricha-inodzorwa nharaunda kuti dzingadzivise nzvimbo dzexidation uye kukuvara kwemukati.
●Tembiricha yekushisa:Yakakodzera kuchengetedza tembiricha ndeye 20-30 ° C
●Kurongedza:Inorema-basa yemapuranga crates ine yemukati foam buffers uye moisture-inopesana firimu
●Kubata:Shandisa isiri-simbi inotsvedza uye kusimudza zvishandiso kuti udzivise kukuvadza kwakashata. Dzivisa kuyerera magetsi pane zvakaoma nzvimbo kudzivirira chipping kana kupaza.
Performance Preanss:
● Kuenderana kwekuenderana kuri pasi pekugara uchiita eaf mashandiro
● Yakavimbika oxidation kuramba uye masimba emuchina
● Chisarudzo chehupfumi chekushanda zvine mwero zvinoitwa nemwero zvinodikanwa
● Zvinoenderana neindasitiri-standard rp-giredhi nipples
● Inoda kudzora chiviridzo chevira chinokonzerwa neyakawandisa cte
