Sut blastim ol masin samting
Ol wear pat blong hae, medel mo low kromium mo hae manganes steel we oli matjem wetem ol masin blong blastem blong sut, tritmen blong sanbij, ol ges silinda ikwipmen, etc{{0} Ol wear resistens blong ol masin blong sut blong sut we oli sutum i kasem o bitim foren level blong sem taem.
Ol wear-resistant spare pat we fektori bilong fektori bilong mipela i kamapim i gat gutpela lukluk kwaliti na wanpela longpela wear-resistant sevis laip{{2} Sevis laip bilong ol i wankain o winim bilong ol impot spare pat, na i daunim tru frikwensi bilong ol spesel pat riplesmen bilong ol yusa na bringim ol gutpela ekonomik benefit, kisim bikpela preis long ol yusa{3}} .
Long prodaksen bilong ol samting i no inap bagarap, em i mas pasim bikpela samting long na adoptim ol proses meja bilong klinim ol samting bilong pasim wear-resistant long kamapim gut na strongim ol metalujikel kwaliti bilong ol grein baundri long ol wear-resistant kasting, na long dispela rot ol i mekim gutpela moa long ol komprehensif mekanik samting na sevis laip bilong ol wear-resistant kasting{4}} .
Ol wok bilong klinim wok we ol i ken kamapim long prodaksen long kamapim gutpela sevis laip bilong ol hap bilong masin bilong sutim sut i kamap olsem:
1. Yusim ol klinpela pe bilong paia na ol kain kain ferroalloi.
2. Selektim hai-kwaliti refrakteri furnace lining samting.
3. Long taim bilong melting proses, ol mak bilong presipitasen deoksidesen na fainel deoksidesen i mas adoptim na strongim.
4. Long taim bilong melting proses, ol i adoptim planti slag-meking na planti slag striping proses meja na strongim.
5. Strongim namba wan proses bilong bagarap long oven na namba tu proses bilong bagarap long ladle.
6. Long ples we ol kondisen i larim, ol proses bilong stretim ol of-furnas olsem AOD na LF rifain proses i ken kamap.
7. In the casting process, a semi-closed gating system is adopted (i.e., the cross-sectional area of the direct gate is larger than that of the mold runner, and the total cross-sectional area of the inner gate is larger than that of the mold runner - which has a good slag blocking effect), and ceramic filter screens are added to the gating system, etc.
8. Yusim ol klinpela ain ladles na tipot ladel, na holim ol ain ladel i stap klin long daunim ol samting i stap insait long oksijen (daunbilo long 30ppm), haidrojen, naitrojen na ol narapela ges, na tu, ol salfaid, oksait (FeO .<0.5%), silicates and other inclusions (<0.5%) in the wear-resistant materials to the lowest level.
