Ol samting bilong lainim samting bilong mil mil.
Bikpela kromium aloi kast ain i save makim aloi waitpela ain i gat kromium konten bilong 12-30% na wanpela kabon i stap insait long 2.4-3.6%{{2} Long rot bilong hai aloying na hat tritmen, martensait o austenit o wanpela miks bilong tupela matriks na spesel karbaid bilong kromili lining plet i ken kisim i kisim i kam bilong {{3} 3} the palat bilong kromium i gat kromiam long kromium i ken kisim {{3} 3} the palat bilong kromium bilong kromium i ken kisim {{3} 3} the palat bilong kromium bilong kromium i ken kisim i kisim i kam long eutectic carbide with a microhardness of HV1300-1800, which is dispersed in a broken network and isolated form on the martensite (the hardest structure in the metal matrix) matrix, reducing the impact on the matrix. The splitting effect is equivalent to embedding high-hardness particles on the matrix. It not only has good wear resistance, but also has high hardness and good toughness, we i antap tru long hat bilong ol simen karbides na ol komon mineral grinding tes. Olsem na, hai kromium aloi lain plet i gat bikpela strong, strong na bikpela wear resistens, na pefomens bilong en i makim nau hai level bilong ol metal wear-resistant materiel i no inap bagarap i stap.
Proses bilong wokim ol balmil.
1. Ol i save yusim intamediet frikwensi lektrik furnas long smeltim, maikro-aloi, belhat na kastim hai-kwaliti kabon stiel, hai kromium na ol narapela aloi samting long wanpela go.
2. Yusim vekim kasting na daireksenel solidifikesen teknoloji, ol grein i kamap gutpela tru na ol i rausim ol samting bilong kasting i pinis.
3. paia tritmen na wara strong proses. Kwenching na tempering senisim intanel straksa bilong lining plet. Em i hat long 1100 digri bilong lukautim hat, na bihain em i kam aut long furnace{{4} Bihain long kemikal i strongim bel bilong em long 600 digri, na bihain em i kisim liklik tempereja i go insait long win i kol, na bihain em i stap aninit long liklik temperaja i go insait long win i go insait masin. Long sait bilong pefomens, Dongchen i gat bikpela samting tru long hat na strong bilong laining bod.
