Cr12 chikamu simbi inogona kushandiswa ku:

a) silicon kufa inonyanya kushandiswa kune diki dynamic loaGBg mamiriro anoda yakakwirira kupfeka kuramba, yakapusa chimiro kudhirowa uye blanking inofa.
b Iyo sisitimu yekugadzira benGBg mold inoda kupfeka kwakanyanya, iyo yakaoma chimiro chepunch, kufa, kuisa, kuita punch, kana kufa kunokurudzirwa, kuoma 60 ~ 64HCR.
c) kugadzira kudhirowa kufa kufa kupfeka kunodiwa, zvinokurudzirwa kuomarara 62 ~ 64HCR.
d) yeAnti-kutonhora aluminium extrusion die punch, inokurudzirwa kuomarara 60 ~ 62HCR.
e) ye benGBg carbon content ye 0.65% kusvika 0.80% proof builGBg simbi, kuoma 60 ~ 62HCR.
f) inogona kushandiswa kuvharisa kufa, punch, mavhiri anotenderedza, shear blades, kutonhora heaGBg kufa, ivhu mold.
g) inogona kushandiswa kune thermoset epurasitiki molGBg molds.

f) inogona kushandiswa kuvharisa kufa, punch, mavhiri anotenderedza, shear blades, kutonhora heaGBg kufa, ivhu mold.
g) inogona kushandiswa kune thermoset epurasitiki molGBg molds.

Kugadzira Cr12 simbi zvinhu

Preheat zvishoma nezvishoma kusvika 900 ~ 950 ° C wobva wawedzera tembiricha nekukurumidza kusvika 1050-1100 °C. Usapfure pasi pe1020°C. Wobva watonhodza iyo Cr12 zvishoma nezvishoma mushure mekugadzira.

Annealing yeCr12 simbi zvinhu

GB Cr12 chishandiso simbi inounzwa mamiriro akajairwa pa annealing uye muchina. Kana zvichidikanwa re-annealing. Pisa kuCr12 simbi 900 °C uye Nyara zvakazara, wozotonhorera muchoto. Mushure mekuvhara, iyo Cr12 kuburitsa kuomarara ndeye 255HB Max.

Stress Relieving yeCr12 simbi zvinhu

Ndeipi maturusi akagadzirwa kubva kuCr12 alloy tool simbi akagadzirwa zvakanyanya kana pasi, kudzoreredzwa kwemukati madhiri kunokurudzirwa kusati kwaoma kudzikisa mukana wekukanganisa. Kudzoreredza kushushikana kwakakosha, kuderedza kushushikana kunofanirwa kuitwa mushure mekugadzira hutsinye. Kuti uwedzere kudzvinyirira, kupisa chikamu zvakanyatsonaka kusvika 600-650 ° C, bvumira nguva yakanaka yekunyura (maawa maviri pa25mm yechikamu chekutonga). Kutonhorera muchoto kana mumhepo. Maturusi ngaapedzwe kugadzirwa asati aoma.

Kuomeswa kweCr12 simbi zvinhu

GB Cr12 Delivery mamiriro anowanzo ari Annealing, saka kuomesa kunodiwa. Pisa maturusi eCr12 muchoto chinodzorwa, kana isina choto chinodzorwa, kuomeswa kwepakiti kunokurudzirwa zvakasimba. Pre-heat Cr12 chishandiso simbi kusvika 750 ~ 800 ° C, sora nguva yakakwana kusvika kupisa kwapfuura. Zvino yakaunzwa kusvika 1000-1040 °C, kutonhora mumhepo kana kudzima mafuta.

Kupisa kweCr12 simbi zvinhu

Pisa iyo GB Cr12, Pisa zvakafanana kune tembiricha inodiwa ichibvumira nguva yekunyura yemaawa maviri pa25mm yechikamu chekutonga. Bvisa kubva muchoto uye bvumira kutonhora mumhepo. Yakasiyana tempering tembiricha inowana kuoma kwakasiyana. Yakajairika kupisa ndeye 204 ° C, mushure mekupisa kuoma 61HRc Min.

Welding yeCr12 simbi zvinhu

Kazhinji, isu hatikurudzire iyo welGBg yealloy tool simbi asi vashandisi dzimwe nguva vanosarudza weld kuitira kudzivirira mutengo wekugadzirisa zvakare. Zvinofanira kuyeukwa kuti giredhi iyi isimbi inoomesa mhepo uye kuti mu welGBg nzvimbo ye weld inowana tembiricha inosvika 1000 ° C. Kutsemuka kungangoitika panguva yekutonhodza kunze kwekunge matanho akakodzera akatorwa. Nzira dzakakurumbira dze welGBg iatomic hydrogen uye argon arc. Isu tinokukurudzira kuti ubate wako welGBg consumables supplier uyo anofanira kukupa rubatsiro ruzere uye ruzivo nezve welGBg alloy tool steels.

Nitriding yeCr12 simbi zvinhu

Cr12 alloy tool simbi inogona kuve nitrided kuti ipe yakaoma pamusoro kesi. Mushure meiyo nitriGBg yekupisa kurapwa, iyo Cr12 inobva yanyanya kushingirira kupfeka uye kukukurwa. NitriGBg inowedzerawo kuramba kune ngura.

Final Kukuya kweCr12 simbi zvinhu

GrinGBg iyo GB Cr12 Simbi. Sarudza iyo chaiyo giredhi revhiri mukubvunzana negrinGBg vhiri mugadziri. Ita shuwa kuti grinGBg vhiri riri muchimiro chakanaka kuburikidza nechakakodzera chekupfeka. Wet grinGBg isarudzo inosarudzika uchishandisa yakawanda inotonhorera inotonhorera. Kana yakaoma grinGBg inoshandiswa ipapo shandisa vhiri rakapfava.
