Ndezvipi zvakanakira zvehupfumi zvinogona kuunza kushandiswa kwechikafu chemhando yepamusoro che petroleum coke carbon chinowedzera kumakambani?

Kushandiswa kwezvishandiso zve petroleum coke recarburizers zvemhando yepamusoro zvinogona kuunza mabhenefiti akakwana ehupfumi mumabhizinesi muzvinhu zvakawanda, kusanganisira kuderedza mari yekugadzira, kuvandudza mhando yechigadzirwa, kugadzirisa mashandiro ekugadzira, uye kuwedzera mabhenefiti ekuchengetedza nharaunda. Ongororo chaiyo ndeiyi inotevera:

I. Kuderedza Mari Yekugadzira uye Kuvandudza Kushandiswa Kwezvinhu

Kuderedza Kushandiswa kweSimbi yeNguruve: Zvishandiso zve petroleum coke zvemhando yepamusoro, zvine graphitized, zvine huwandu hwakagadzika hwekabhoni (kazhinji ≥98%) uye tsvina shoma, zvinogona kutsiva zvinobudirira kabhoni inowanikwa musimbi yenguruve. Sekureva kwedata reindasitiri, kushandisa iyi recarburizer kunogona kuderedza kushandiswa kwesimbi yenguruve ne20%-40%, zvichideredza mutengo patani ye castings neinenge 300-500 yuan. Semuenzaniso, kambani yekugadzira foundry yakachengetedza mari inodarika miriyoni imwe yekutenga simbi yenguruve pagore nekuvandudza chiyero che recarburizer.

Kuvandudza Mwero weKunyudzwa kweMafuta: Kugadziriswa kweGraphitization kunoita kuti maatomu ekabhoni agadzire chimiro chakarongwa, zvichiwedzera mwero wekunyudzwa kubva pa60% yezvinogadziriswazve zvemazuva ose kusvika pa90%-95%. Izvi zvinoreva kuti hapana chinodiwa kuti uwane huwandu hwekabhoni hwaunoda, zvichideredza mari yezvinhu. Semuenzaniso, mukugadzira simbi dzemagetsi, kuwedzera 0.1%-0.3% yezvinogadziriswazve zvegraphitized kunogona kugadzirisa huwandu hwekabhoni musimbi yakanyungudutswa ukuwo kuchipfupisa nguva yekunyungudutswa nemaminitsi gumi nemashanu kusvika makumi maviri uye kuderedza kushandiswa kwesimba.

II. Kuvandudza Hunhu hweChigadzirwa uye Kuvandudza Kukwikwidzana kweMusika

Kuvandudza Kushanda Kwekugadzira: Magirazi madiki egrafiti ari muzvigadziko zve petroleum coke zvemhando yepamusoro anogona kushanda semakristaro, zvichikurudzira kukura kwakafanana kwema graphite flakes musimbi yakakandwa. Musimbi yakakandwa yegrey, izvi zvinogona kuwedzera simba rekudhonza ne15%-25%; musimbi yakakandwa, zvinogona kuwedzera maronda ne10%-20%. Semuenzaniso, mushure mekushandura kune iyi recarburizer, mugadziri wemabhuroko einjini yemotokari akaderedza mwero wekukanganisa kwekukandwa kubva pa15% kusvika pa3%, zvichivandudza zvakanyanya goho rezvigadzirwa.

Kusangana Nezvinodiwa Zvepamusoro: Hunhu hwesarufa yakaderera (≤0.05%) uye nitrogen shoma (≤400ppm) hunoita kuti graphitized petroleum coke recarburizers ive zvinhu zvakakosha pakugadzira mota dzemhando yepamusoro, michina yemagetsi emhepo, nezvimwe zvinhu zvakakosha. Kushandisa recarburizer iyi kunogona kudzivirira zvikanganiso zvekukanda zvakaita sekutsemuka uye maburi anokonzerwa nekusvibiswa kwesarufa nenitrogen, zvichiwedzera kukosha kwechigadzirwa.

III. Kuvandudza Kushanda Kwekugadzira uye Kupfupisa Kutenderera Kwekugadzira

Kuwedzera Kukurumidza Kwekunyungudutsa: Panguva yekugadzira simbi, michina yemhando yepamusoro ye graphitized petroleum coke recarburizers inogona kunyunguduka nekukurumidza uye kupararira zvakaenzana, zvichideredza nguva yekunyungudutsa. Semuenzaniso, chigayo chesimbi chakapfupisa kutenderera kwacho kwekunyungudutsa kwechoto chemagetsi ne15%-20% mushure mekushandisa iyi recarburizer, zvichiwedzera kubuda kwesimbi pagore nematani anopfuura zviuru gumi.

Kugadzirisa Maitiro Ekugadzira: Kuchena kwakanyanya uye kusviba kushoma kwe recarburizer kunodzivirira oxidation uye kuora pakupisa kwakanyanya, zvichideredza kushanduka-shanduka kwekugadzirwa. Semuenzaniso, mukukanda nguva dzose, kushandisa recarburizer iyi kunogona kuchengetedza huwandu hwekabhoni hwakagadzikana musimbi yakanyungudutswa, kudzivirira matambudziko emhando yekukanda anokonzerwa nekushanduka-shanduka kwehuwandu hwekabhoni.

IV. Kuvandudza Mabhenefiti Ekuchengetedzwa Kwezvakatipoteredza uye Kuzadzisa Zvinodiwa zveKubudirira Kunogara Kwenguva Refu

Kuderedza Kusvibiswa Kwemhepo: Hunhu hwesarufa shoma uye nitrogen shoma ye graphitized petroleum coke recarburizers inoderedza zvakanyanya kuburitswa kwe sulfur dioxide ne nitrogen oxides panguva yekutsva. Semuenzaniso, mushure mekushandisa iyi recarburizer, kambani yekugadzira foundry yakaderedza mitengo yayo ye flue gas desulfurization ne40% uye yakaderedza kuburitswa kwe sulfur dioxide pagore nematani akawanda.

Kukurudzira Kudzokorodza Zviwanikwa: Munguva yekugadzira magirafu epetroleum coke recarburizers ane graphitized, kupisa kwemarara kunogona kuwanikwa kuti kugadzirwe magetsi, zvichichengetedza 300 kWh yemagetsi patani yechigadzirwa. Pamusoro pezvo, gasi rekumashure rinogona kuendeswa kune mamwe maindasitiri (akadai semafekitori eceramic) semafuta, zvichiita kuti zviwanikwa zvishandiswe zvakanaka. Semuenzaniso, kuburikidza nemuenzaniso wehupfumi hwakatenderera, nzvimbo yezvekuchengetedza nharaunda yakaderedza kuburitswa kwecarbon nematani 1.2 patani yerecarburizer inogadzirwa.
