30CrMnSiA Umbhobho weNtsimbi oshinyeneyo waseWall

30CrMnSiA Thick Wall Ingxubevange Steel Umbhobho Featured Umfanekiso

Inkcazelo emfutshane:

I-30CrMnSiA i-alloy pipe yentsimbi inamandla amakhulu kodwa ukusebenza kakubi kwe-welding.Emva kokufudumala, inamandla aphezulu kunye nokuqina okwaneleyo, kwaye inobunzima obuhle.Emva kokucinywa kunye nokuthambisa, inokwenziwa i-shafts yevili lokusila, iigiya kunye ne-sprockets.Inokwazi ukuqhubekeka kakuhle, i-deformation encinci, kunye nokumelana nokudinwa okuhle kakhulu.Isetyenziselwa iishafti, iintsimbi zepiston, njl.njl. Isetyenziselwa iindawo ezahlukeneyo zokunganxibi kwiimoto kunye neenqwelomoya.

Impahla Ephathekayo

1. Amandla aphezulu kunye nokuqina: Inamandla esivuno esihle kunye nokomelela kokuqina, kunye nokuqina okubalaseleyo.

2. Ukumelana nokunxiba kakuhle: Inqanaba eliphezulu lobunzima lenza ukuba lilungele ukusetyenziswa kwiindawo eziphezulu zokunxiba.

Inkqubo yoNyango lobushushu

Ukucima: Ukufudumala ukuya kwi-880 ° C ukuya kwi-920 ° C, kulandelwa ukupholisa ngokukhawuleza emanzini okanye kwioli.

Ukufudumeza: Ukufudumeza ukuya kuma-200°C ukuya kuma-500°C ukuphumeza ubulukhuni obunqwenelekayo kunye nokuqina.

Iinkalo zeSicelo

1. Amacandelo abalulekileyo olwakhiwo, afana nezixhobo zokumisa inqwelomoya, iitanki kunye nezixhobo zesithuthi esixhotyisiweyo.

2. Izibophelelo eziphezulu kunye nezixhumi.

3. Iigiya eziphezulu zomthwalo kunye neebheringi.

Ubume bokuhanjiswa

Ukunikezelwa ngonyango lobushushu (oluqhelekileyo, olune-annealing okanye ubushushu obuphezulu) okanye ngaphandle konyango lobushushu.

Inamandla amakhulu, kodwa yintsimbi ephakathi kunye nekhabhoni epholileyo enobunzima obukhulu, ngoko ukusebenza kwayo kwe-welding kubi kakhulu.

Emva kokufudumala, izinto eziphathekayo zinamandla aphezulu kunye nokuqina okwaneleyo, kwaye zinobunzima obuhle.Emva kokucima kunye nokufudumeza, izinto eziphathekayo zinokusetyenziswa njengeentsimbi zokusila, iigiya, kunye ne-sprockets.I-blade yokugaya nge-carbide milling cutter kunye ne-polish ngomatshini wokupolisha.Kufuneka kungabikho ngxaki ukuba uburhabaxa bomphezulu bufikelela ku-3.2.Izinto eziphathekayo zimnyama ngombala, kwaye i-galvanizing inokuphucula umgangatho womphezulu kwaye inqande irusi.
