60Si2Mn inopisa yakakungurutswa simbi yakatenderedzwa mbariro

60Si2Mn chitubu simbi inoshandiswa zvakanyanya silico-manganese chitubu simbi ine simba rakati wedzerei, elasticity uye kuoma kupfuura 55Si2Mn. 60Si2Mn chitubu chesimbi indasitiri inogadzira zvitubu zvakapfava zvine mutoro wakakura kana zvitubu zvecoil zvine dhayamita isingasviki 30mm. Yakakodzerawo kugadzira zvitubu zvinodzivirira kupisa zvine svikiro risingasvibisi nekushanda tembiricha iri pasi pe250 ° C uye ine inochinjana mutoro uye kushushikana kwakanyanya. Makuru akakosha coil zvitubu zvekushanda pasi, pamwe nemotokari kuvhunduka kunyudza masisitimu.

Elongation δ10 (%): ≥5
Kuderera kwenzvimbo ψ (%): ≥25
Kuoma: kupisa kupisa, ≤321HB; kutonhora kudhirowa + kupisa kurapwa, ≤321HB

Tsanangudzo yekupisa:

60Si2Mn kupisa kurapwa kutsanangurwa: kudzima 870 °C ± 20 ° C, kutonhora kwemafuta; kupisa 480 ° C ± 50 ° C (kunyanya zvinodiwa, ± 30 ° C).
Metallographic sangano: tempered troostite.

Mamiriro ekutumira: Simbi inopisa inounzwa mukupisa-kupisa kana kusapisa-kupisa, uye simbi inotonhorera inounzwa mumamiriro ekupisa.
Kupisa kutenderedza kuburitsa zvirevo: 2.0 ~ 18.0mm, ine uye isina annealing. Kutonhora kutenderedza kuburitsa zvirevo: 0.3 ~ 4.3mm (simbi tambo)

Kupisa kurapwa nzira

60Si2Mn kupisa kupisa nzira ndeye isothermal tempering uye grading quenching, sub-tembiricha kudzimwa uye yakanyanya tembiricha kudzikama, deformation kupisa kurapwa maitiro. Iyo nzira inogona kunyatso kuvandudza simba uye hupenyu hwebasa re60Si2Mn chitubu chesimbi. 60Si2Mn ndeyechitubu simbi, yakakodzera kugadzira mota mashizha chitubu. 60Si2Mn chitubu chesimbi yekupisa kurapwa isothermal tempering uye grading quenching, sub-tembiricha kudzimwa uye yakanyanya tembiricha kupisa, deformation kupisa kurapwa maitiro. Iyo nzira inogona kunyatso kuvandudza simba uye hupenyu hwebasa re60Si2Mn chitubu chesimbi.

density

60Si2Mn density ye7.85g / cm3. 60Si2Mn inoshandiswa zvakanyanya silicon manganese chitubu simbi, simba, elasticity uye kuoma kupfuura 55Si2Mn zvishoma zvishoma. Inokodzera mota dzenjanji, indasitiri yemotokari yetirakita kugadzira hombe yezvitubu zvakapfava kana waya dhayamita ye30mm pazasi pechitubu checoil.
