20 # sheet eshushu esongwayo

(1) Iimpawu Intsimbi yeyomgangatho ophezulu we-carbon carbon steel, i-extruded extruded, i-carburized kunye nentsimbi eqinile. Intsimbi inamandla aphantsi, ukuqina okulungileyo, iplastiki kunye ne-weldability. Amandla e-tensile yi-253-500MPa, kwaye ubude yi-≥24%.
Iipropati ze-20 ngokusisiseko zifana nezo zentsimbi ye-15, kodwa amandla angaphezulu kancinci. Usetyenziso: lulungele ukwenziwa kweendawo ezincinci kunye neziphakathi ze-carburizing kunye ne-carbonitriding ezingabalulekanga ekwakhiweni kweemoto, iitrektara kunye nokwenziwa koomatshini ngokubanzi, njengezihlangu zebrake, i-lever shafts, iifolokhwe zesantya sebhokisi yegiya, iigiya zokuhambisa kunye neeCamshafts kwiitrektara, ukunqunyanyiswa kwe-equalizer shafts, i-equalizer bushings yangaphakathi nangaphandle, njl.; isetyenziselwa ukwenza iindawo ezahlukeneyo zoomatshini ezingagxininisi kodwa zifuna ukuqina okuphezulu phantsi kweemeko ezishushu okanye eziqhelekileyo; kumatshini onzima kunye nobukhulu obuphakathi wokuvelisa oPhakathi, njengeentonga ezibopheneyo okanye ezicinezelweyo, amakhamandela, imilenze, imikhono, i-clamps, njl njl. Kwi-injini ye-steam kunye ne-boiler yokuvelisa ishishini, isetyenziswa kakhulu kwimibhobho, iiflange, iiheader kunye nezibophelelo ezahlukeneyo. ukusebenza kumajelo angabonakaliyo kunye noxinzelelo lwe-≤6N / isikwere kunye nobushushu be-≤450℃; esetyenziselwa ukwenza iminqamlezo koololiwe, oololiwe kunye nezithuthi Ii-Castings ezinjengeentloko kunye neepiston.
Ukulungelelanisa kunokukhuthaza i-spheroidization yentsimbi, ukucokisa i-proeutectoid ferrite enkulu, kunye nokuphucula ukusebenza kokusika okungenanto ngaphantsi kwe-160HBS.
Indlela yenkqubo yeendawo zokudayela zentsimbi yile: ukugquma→ukubumba idayiti akukho nto→ukubamba→umatshini orhabaxa omatshini→ukubumba okubandayo okuphumayo→ukufakwa kwakhona kwekristale→ukugqiba oomatshini→ukucima,ukuthambisa→ukusila nokupholisha→ukudityaniswa.
(2) Ukuhanjiswa kwemeko kunye nobunzima Imeko engatshisiyo, ubunzima ≤156HBS.

Ukubunjwa kweekhemikhali zomgangatho we-JB / T 6057-92 yentsimbi (iqhekeza elikhulu,%)

Iimpawu zoomatshini
(5) Iqondo lotshintsho lwenqanaba (ixabiso eliqikelelweyo) Ac1=735℃, Ac3=855℃, Ar3=835℃, Ar1=680℃
(6) Ubume besiqhelo Ubushushu bungama-920 ~ 950℃, kwaye isithando somlilo sipholile. Ubunzima buyi-131 ~ 156HBS.
(7) Ukucaciswa kokuthambisa unyango lweendawo ezicinezelekileyo ezibandayo Ubushushu yi-700 ~ 720 ℃, ixesha lokubamba ngu-8 ~ 15h, kwaye izinga lokupholisa liyi-50 ~ 100 ℃ // h, kwaye ubushushu buhla ukuya kwi-550 ~ 600 ℃ kunye neziko, kwaye iziko lipholiswa ngumoya.
Ubunzima phambi kokuba unyango ≤143HBS, kwaye ubunzima emva kokuthambisa ≤131HBS.
(8) Ukucima iinkcukacha zoBubushushu 910℃±10℃, ukupholisa nge-10% ye-NaCl brine.
(9) Umlinganiselo wamandla esivuno fy=245Mpa, imodyuli elastiki E=206Gpa, umlinganiselo wePoisson ν=0.3.
(10) Amandla okucheba ngama-275 ~ 392MPa, amandla e-tensile yi-253 ~ 500MPa, amandla emveliso yi-275MPa, kwaye ubude ngama-25%.
(11) Ukushisa kwe-anneal yi-600-650 degrees kuphela, kwaye ixesha lokubamba li-1-2h.
