10 # Umbhobho wentsimbi ongenamthungo
Inkcazelo emfutshane:
Iinkcukacha ngemveliso:
Ububanzi bangaphandle bombhobho wensimbi 20-426
Umbhobho wentsimbi ubukhulu bodonga lwe-20-426
Ukwenziwa kweekhemikhali:
● Inombolo ye-10 yensimbi engenamthungo yokwakheka kweekhemikhali:
Carbon C: 0.07~0.14″ isilicon Si: 0.17 ~ 0.37 Manganese Mn: 0.35 ~ 0.65 Sulfur S: ≤0.04 Phosphorus P: ≤0.35 chromium Cr: ≤0.15 I-Nickel0 ≤5 ye-Nick0: ≤0.
Ipropathi yoomatshini:
Iimpawu zobuxhakaxhaka beNo. , ubulukhuni: ubushushu,≤156HB, ubungakanani besampulu: 25mm.
Umgangatho ophezulu wekhabhoni yesakhiwo sentsimbi:
No. 10 umbhobho intsimbi ingenamthungo ayiqulathanga ezinye izinto ialloy (ngaphandle izinto ezishiyekileyo) ngaphandle carbon (C) element kunye nomlinganiselo othile lesilicon (Si) for deoxidation (ngokubanzi akukho ngaphezu 0.40%), manganese (Mn) (ngokubanzi hayi ngaphezu kwe-0.80%, ukuya kuthi ga kwi-1.20%) i-alloy element.
Intsimbi enjalo kufuneka ibe neekhemikhali zombini kunye neempawu zomatshini.Iziqulatho zesulfure (S) kunye nephosphorus (P) zilawulwa ngokubanzi ngaphantsi kwe-0.035%.Ukuba ilawulwa ngaphantsi kwe-0.030%, ibizwa ngokuba yintsimbi ephezulu, kwaye "A" kufuneka ifakwe emva kwebanga, njenge-20A;Ukuba i-P ilawulwa ngaphantsi kwe-0.025% kwaye i-S ilawulwa ngaphantsi kwe-0.020%, ibizwa ngokuba yintsimbi eyongezelelweyo ephezulu, kwaye "E" kufuneka yongezwe emva kwebanga ukubonisa umehluko.Ukwenzela ezinye izinto ezishiyekileyo zokuxuba eziziswe kwintsimbi ngezinto ezikrwada, ezifana nechromium (Cr), nickel (Ni), ubhedu (Cu), njl., umxholo weCr≤0.25%, Ni≤0.30%, Cu≤0.25%.Ezinye iintlobo zemanganese (Mn) ziqulathe ukuya kuthi ga kwi-1.40%, ezaziwa njengentsimbi yemanganese.
No. 10 ingenamthungo umbhobho wentsimbi formula wokubala :[(idayamitha yangaphandle - udonga ubukhulu)* udonga ubukhulu]*0.02466=kg/m (ubunzima ngemitha)
