IBha yokuvuthela KwiPlate ye-Steel MillCasting Liner

 

 

I-high -i-chromium cast iron liners zinokunganyangeki okuphezulu kunye nempilo ende yenkonzo, kwaye kudala zibonwa lishishini. Ukusebenza kwabo okuphezulu kubonisa inqanaba eliphezulu lentsimbi yangoku yokunxiba{2}}izinto ezixhathisayo. Nangona kunjalo, ngenxa yomxholo we-alloy ephezulu kunye neendleko eziphezulu zokuvelisa, ukunyuswa kwabo kunye nokusetyenziswa kwabo kuye kwachaphazeleka kumanqanaba ahlukeneyo, okubangela ukuba bangasetyenziswa ngokubanzi. -Iintsimbi eziphoswe ngechromium eziphezulu zaziwa ngokomelela kwazo okuphezulu, ukuqina kunye nokumelana nokunxiba. Ziye zasetyenziswa ngokubanzi kwiibhola ezinkulu zebhola kwishishini le-samente phesheya, kunye nobomi benkonzo jikelele malunga neminyaka eyi-8, kwaye kwigumbi lesibini nelesithathu, linokuba ngaphezu kweminyaka eyi-12, kwaye ezinye zinokuhlala iminyaka engama-20, zibonisa ukuxhathisa okugqwesileyo.

 

 

 

Ephakamileyo-ipleyiti yealloyi yechromium

1. Ubume beMaterial: Ukunxiba okuphezulu kwe-chromium alloy cast-i-resistant liner yenziwa ikakhulu yichromium, carbon, molybdenum, nickel kunye nezinye izinto. Umxholo wechromium udla ngokuba phakathi kwe-12% kunye ne-30%, kwaye umxholo wekhabhoni yi-1.0% ukuya kwi-3.0%. Uvavanyo lokubunjwa kweekhemikhali zomenzi othile ophezulu we-chromium alloy liner lubonisa ukuba umxholo we-chromium ngu-25%, umxholo wekhabhoni ngu-2.0%, kunye nomxholo we-molybdenum yi-2.5%, kwaye iqulethe inani elincinci le-nickel kunye ne-vanadium, ehlangabezana neemfuno zecandelo eliphezulu le-chromium ephonswe kwi-95 GB / Tpule74 ye-iron sti.
2. Iimpawu ze-metallographic: Ubume bemetallographic bokunxiba kwe-chromium alloy cast ephezulu{0}}i-resistant liner ine-matrix ye-martensite, i-eutectic carbides kunye ne-secondary carbides. I-eutectic carbides ihanjiswa kwinethiwekhi eqhubekayo okanye engapheliyo, kunye nobunzima obufikelela kwi-HV1600. Uvavanyo lwe-metallographic lomgca othile lubonisa ukuba umlinganiselo we-eutectic carbides yi-35%, isasazwe ngokulinganayo kwi-matrix ye-martensite, iqinisekisa ukuxhathisa okugqwesileyo.
3. Iimpawu zokusebenza koomatshini: I-chromium alloy cast cast enxitywayo-isixhobo esixhathisayo sinobulukhuni obuphezulu kunye nokungagugi. Ubunzima be-Rockwell HRC bunokufikelela kwi-58-65. Obona bunzima belayini ethile yi-HRC62, kwaye kuvavanyo lokunxiba lwesanti yequartz, umlinganiselo wokunxitywa yi-0.08g/cm kuphela. Ngokumalunga nokuqina kwempembelelo, amandla okufunxa impembelelo anokufikelela kwi-15-25J. Amandla okufunxa impembelelo yohlobo oluthile lomgca ovavanyiweyo phantsi kwempembelelo ye-20J yamandla kukuba akukho zintanda okanye iifracture ezenzekayo.
4. Amanqaku aphambili enkqubo yokuphosa: Umgca we-chromium ophezulu we-alloy uphoswa kusetyenziswa ukuphosa kwesanti okanye ukuphosa ugwebu olulahlekileyo. Ukuchithwa kwesanti, izinto zokubumba zikhethwa njengesanti ye-silica kunye ne-resin, kwaye isikhunta kufuneka somiswe kwiqondo lokushisa eliphezulu. Kwinkqubo yokuphosa i-liner, ukushisa kokumisa yi-300 degree, kwaye ixesha lokubamba liyi-4 iiyure ukukhusela iziphene zokuphosa. Ekulahlekeni kwe-foam elahlekileyo, ukubunjwa kwe-foam kufuneka kufakwe ngepeyinti ye-refractory, yomiswe, kwaye emva koko iphantsi koxinzelelo olubi. I-liner eveliswa ngumenzi othile ngenkqubo ye-foam elahlekileyo inobunzima bomhlaba u-Ra <12.5HB, ngokuchaneka kwenqanaba le-CT9.
5. Inkcazo yenkqubo yokushisa ukushisa: Ukunyangwa kobushushu bomgca ophezulu we-chromium alloy liner kubandakanya ukucima kunye nokuvutha. Iqondo lokushisa lokucima liyi-950-1050℃, kwaye ixesha lokubamba lichongwa ngokuhambelana nobukhulu. Kwi-liner ye-20mm, ixesha lokubamba liyi-2 iiyure. Ukupholisa ioli okanye ukupholisa umoya kusetyenziswa. Ukuqina komgca othile emva kokucinywa yi-HRC60. Iqondo lokushisa elifudumeleyo liyi-200-300℃, kwaye ixesha lokubamba liyi-2 iiyure ukuphelisa uxinzelelo lwangaphakathi. Amandla okufunxa impembelelo ye-liner ethile emva kobushushu anyuka nge-10%, ngelixa ugcina ubulukhuni obuphezulu.
