CrWMn yotentha yozungulira zitsulo zozungulira

CrWMn kufa mbale zitsulo ndi aloyi chida zitsulo, mafuta kuzimitsa otsika mapindikidwe ozizira ntchito kufa steel.The wearability zitsulo, chifukwa kujowina gawo lalikulu la 1.20% ~ 1.60% ya tungsten, kupanga carbides kotero pambuyo quenching ndi kutentha otsika kukhala ⼀kuuma ndi Abrasion resistance.Tungsten imathandiza kuti njere zisapangike chitsulo mosavuta. Chitsulochi chimakhudzidwa ndi kupanga carbon, zomwe zingachititse kuti tsambalo liwonongeke. ili ndi zolakwika monga kusweka mosavuta ndi kugaya chifukwa cha tsankho la carbide. Kuzimitsa kumakonda kukhala chitsulo cha carbon, ndipo kuchuluka kwa ntchito kumachepetsedwa.Kuuma kwachitsulo ndi kupsa mtima kwachitsulo komanso kulimba kwachitsulo cha chromium ndi chromium silicon chitsulo pambuyo pake. kuzimitsa ndi zabwino, ndipo kulimba ndi kwabwino.
CrWMn makamaka ntchito mpweya chida zitsulo sangathe kukwaniritsa zofunika gawo lalikulu mtanda, zovuta mawonekedwe a mbali kufa, amafuna zochepa quenching mapindikidwe.
1) Mtundu uwu wa zitsulo chimagwiritsidwa ntchito pokonza zitsulo woonda, zitsulo sanali ferrous, mfundo zofunika katundu kuwala ndi zovuta mawonekedwe ozizira kupondaponda kufa, makamaka m'minda ya wotchi, chida, chidole ndi malonda makampani, etc. hedging austenite zitsulo mbale, silicon zitsulo pepala ndi mkulu mphamvu mbale zitsulo si abwino.

2) makulidwe achitsulo angagwiritsidwe ntchito kupanga zinthu <1 mm wa blanking kufa zovuta zooneka nkhonya, concave kufa, kuika chidutswa, ndi kwambiri ⼀ zingwe zojambula zakuya kufa. Kupanga nkhonya kunawonetsa kuuma kwa 58 mpaka 62 HRC, ndipo kupanga nkhungu ya concave kunanena kuti kuuma 60 ~ 64 HRC.

3) Amagwiritsidwa ntchito poyika nkhonya kufa ndi kukana kwamphamvu kwambiri komanso mawonekedwe ovuta kupindika kufa. Kuuma kwa nkhonya kufa kumalimbikitsidwa kukhala 58 ~ 62HRC ndipo 60-64hrc ikulimbikitsidwa kukhala 60-64hrc popanga nkhonya kufa.

4) A convex die and concave die for cold extrusion die of aluminium parts.The hardness of 60 ~ 62HRC akulimbikitsidwa kufa nkhonya ndi 62 ~ 64HRC akulimbikitsidwa nkhonya kufa.

5) Pakuti ozizira extrusion kufa mbali mkuwa ndi ozizira extrusion kufa ndi kufa mbali zitsulo, analimbikitsa kuuma ndi 62-64hrc.

6) Akapangidwa, amatha kugwiritsidwa ntchito popanga nkhungu zazikulu zomwe zimagwiritsidwa ntchito pamakina opondereza opitilira 1mm, zomwe nthawi zambiri zimakulitsa kuuma kwachitsulo mpaka 50-55hrc. Komabe, zolakwika zowoneka bwino za minofu monga mawonekedwe a banded carbide kapena chromatography yamadzimadzi ziyenera kuchepetsedwa kapena kupewedwa.
