Dispela i bringim yumi i go long bikpela disisen bilong painim ol samting: ESR.

Taim yu painim ol 'raw steel' bilong wokim ol 'high-pressure die casting' (HPDC) mol, yu no inap long makim 'chemical grade' bilong en. Namba wan as bilong 'premature heat checking' em i no rong kemistri, tasol ol 'microscopic non-metallic inclusions' na 'chemical segregation' insait long 'forged block'.

Ol i save meltim ol standet ain insait long wanpela 'Electric Arc Furnace' (EAF). Maski em i no gat bikpela pe, EAF steel i gat ol liklik pipia (salfa, fosforas, oksait). ESR em i wanpela sekenderi rifaining proses. Ol i save melt isi isi 'steel ingot' bilong EAF long rot bilong wanpela 'reactive chemical slag'. Slag i wok olsem wanpela liklik filta, na i save rausim olgeta pipia.

Isotropic Properties:Standet 'forged steel' i gat strong bilong 'directional' (em i strong moa wantaim 'grain' na i no wantaim 'grain' bilong en). ESR i rausim dispela 'directionality'. Wanpela ESR H13 blok em i wankain strong long olgeta sait (transves na longitudinal), na i pasim 'mold' long bruk aninit long ol 'multi-directional injection pressures'.

[Mold and Die Steel Sourcing Guide -> ]

Q1: Yumi ken yusim standet EAF H13 long wanpela aluminium dai-kasting mol na noken yusim ESR long sevim mani?

A: Em i no gutpela long ol longpela prodaksen ran. Standet EAF materiel em i orait long ol sotpela-ran prototaip o low-presa ekstrusen tul. Tasol, long 'high-pressure aluminium die casting, sapos i no gat 'isotropic toughness' insait long EAF 'steel' dispela bai mekim 'heat checking' i go hariap tru, na dispela bai mekim 'mold' i bagarap hariap na i no inap long sevim ol 'raw material'.

Q2: Wanem em i gutpela wok strong bilong SKD61 long aluminium ekstrusen?

A: Long ol 'aluminium extrusion dies' (we i save bungim bikpela 'abrasive wear' na presa), ol i save tanim 'steel' i go antap moa long ol 'die-casting molds, planti taim namel long 48 HRC na 52 HRC.

Q3: Ol i ken stretim wanpela H13 mol we i bruk long rot bilong weldim?

A: Yes, H13 na 1.2344 em ol i ken weldim, tasol em i wanpela hatpela wok bilong wokim ol samting long ain. Ol i mas hatim dispela 'mold' pastaim long 320 digri (600 digri F) pastaim long ol i weldim, na holim dispela 'temperature' long taim bilong stretim, na bihain ol i mas rausim hariap 'stress-' (tempered) bihain long stopim 'Heat-Affected Zone (HAZ) long bruk.

Q4: Ol H13 blok we ol i wokim long giaman i save kamap taim ol i strong yet?

A: Nogat. Ol i save givim 'raw hot work tool steel' long wanpela 'annealed' kondisen (planti taim em i liklik o wankain olsem 235 HB). Long dispela 'soft state', 'manufacturing facility' i ken yusim CNC masin long katim ol kompleks 'cavity geometry' pastaim long ol i salim blok i go aut long mekim laspela 'vacuum heat treatment'.

Q5: Bilong wanem em i bikpela samting long hatim 'mold' long masin pastaim?

A: Taim yu putim 650 digri molten aluminium i go insait long wanpela "kol" (rum tempereja) H13 mol i save kamapim bikpela 'thermal shock' we inap long brukim ain hariap tru. Ol i mas hatim ol 'mould' ausait long 150 digri - 200 digri (300 digri F - 390 digri F) pastaim long ol i stat long wokim bilong daunim 'thermal delta'.
