Codsiyada recarburizers kala duwan
Carburizer waa walxo kiimiko ah oo si wax ku ool ah u wanaajin kara saamaynta carbonization ee alaabta iyo deegaanka birta.Waxaa jira carburizers badan oo loo isticmaalo warshadaha birta iyo birta.Recarburizers kala duwan ujeedooyin kala duwan ayaa leh saameyno kala duwan.
1. Recarburizer graphite artificial
Qalabka ugu muhiimsan ee garaafka macmalka ah waa kookaha batroolka ee budada ah, kaas oo garoonka (ama pregelatinization organic saafi ah) lagu daro sida binder, iyo qadar yar oo qalab kale ah ayaa lagu daray.Iyada oo leh walxo cayriin oo kala duwan, waa la riixaa oo la sameeyaa, ka dibna lagu farsameeyaa jawi aan oksaydheyneynin oo ah 2500-3000 ° C si loo sameeyo garaafka.Ka dib daaweynta heerkulka sare, waxa ku jira dambas, baaruud iyo gaas si weyn ayaa loo dhimay.
Sababo la xiriira qiimaha sarreeya ee alaabta garaafyada macmalka ah, inta badan dib-u-carbiyeyaasha garaafyada macmalka ah ee caadi ahaan loo isticmaalo waxay isticmaalaan agab dib loo warshadeeyay sida chips, electrodes-ka qashinka ah iyo baloogyada graphite marka la soo saaro electrodes graphite ee aasaaska si loo yareeyo kharashka wax soo saarka.Marka la dhalaalinayo birta ductile-ka, si tayada birta ee kabka looga dhigo mid sare, dib-u-karbareiyuhu waa inuu noqdaa graphite macmal ah.
Codsiga recarburizer garaafka: Garaafayeeyaha recarburizer wuxuu wanaajin karaa qaab dhismeedka biraha shubka, si dhakhso ah ayuu u dhalin karaa xudunta garaafka ee birta shubka ah, wuxuu gaabin karaa wakhtiga kaarboonaynta, wuxuuna wanaajin karaa saamaynta carbonization.
2. Recarburizer batroolka kookaha
Coke batroolka waa dib-u-carbuure si weyn loo isticmaalo, kookaha batroolkuna waa wax ka soo baxay sifaynta saliidda cayriin.Saliida hadhaaga ah iyo garoonada batroolka ee lagu helo cadaadiska ama nadiifinta faakuumka ayaa loo isticmaali karaa sidii alaabta ceeriin ee soo saarista kookarka batroolka, iyo kookaha batroolka ayaa la heli karaa ka dib marka la karsado.Soosaarka kookaha batroolka ceyriinka ah wuu ka yar yahay xaddiga saliidda ceyriinka ah, iyo waxa ku jira wasakhda kookaha ee batroolka ceyriinka ah waa sarreeyaa, markaa si toos ah looguma isticmaali karo karburizer ahaan waana in marka hore la miisaamaa.Coke batroolka cagaarka ah wuxuu leeyahay isbuunyo, irbad, midabyo iyo qaabab dareere ah.
Codsiga recarburizer coke batroolka: Coke batroolka recarburizer wuxuu si wax ku ool ah u kordhin karaa heerkulka foornada, kaliya ma kordhin karo heerkulka foornada, laakiin sidoo kale wuxuu wanaajiyaa dhalidda birta, hagaajinta iyo hagaajinta jawiga qallafsan ee birta.
3. Coke iyo Anthracite
Habka birta samaynta foornada qaansada ee korontada ku shaqeysa, kookaha ama anthracite ayaa lagu dari karaa sidii dib-u-burburiye ahaan.Foornada kicinta dhalaalidda birta ayaa dhif ah loo isticmaalaa dib-u-qarxiyaha sababtoo ah dambaska sarreeya iyo waxa ku jira oo kacsan.Calciner-ka waxaa lagu kariyey anthracite, iyo heerkulka calcination waa 1200-1300.Madaw madow, dhalaal macdan ah, kaarboon go'an 85-93, baaruud dhexdhexaad ah iyo ka kooban nitrogen.
Isticmaalka dib-u-carburiyaha dhuxusha la kariyey: Ujeedada dib-u-carburiyaha dhuxusha la kariyey waa in si wax ku ool ah loo kordhiyo kaarboonka oo loo gaabiyo wakhtiga kaarboonaynta.Isticmaalka dib-u-carburiyaha dhuxusha calcined waxay si wax ku ool ah u badbaadin kartaa waqti.
