Iwaranti yomenzi wombhobho wesakhiwo sentsimbi ye-Q345B
Kuluhlu lwemibhobho yensimbi engenamthungo, kukho into ebizwa ngokuba yi-Q345B ipayipi yensimbi engenamthungo, eyeyechungechunge lwe-alloy ephantsi. Phakathi kwezinto eziphantsi kwe-alloy, le nto ixhaphake kakhulu. Q345B umbhobho wentsimbi ongenamthungo wawubizwa ngokuba yi-16Mn umbhobho wentsimbi ongenamthungo. Zininzi iindlela zokuhlela. Ngokwenkqubo yokuvelisa, kukho: umbhobho oshushu oqengqelekayo ongenamthungo kunye nombhobho obandayo oqengqelekayo ongenamthungo. Ngokwenjongo, kukho: umbhobho wensimbi ongenamthungo wesakhiwo ngokubanzi, umbhobho wentsimbi ongenamthungo wokuhambisa ulwelo, umbhobho wentsimbi ongenamthungo kwibhoyila yoxinzelelo oluphakathi kunye noxinzelelo oluphantsi kunye nombhobho wentsimbi ongenamthungo kwibhoyila yoxinzelelo oluphezulu. Ngokomathiriyeli, kukho: umbhobho wentsimbi ekumgangatho ophezulu wekhabhoni yensimbi engenamthungo, umbhobho wentsimbi esezantsi-ingxubevange yensimbi engenamthungo kunye nombhobho wentsimbi ongenamthungo. Umbhobho wensimbi ongenamthungo usetyenziswa ngokubanzi, unokucutshungulwa kwiindawo zoomatshini, ezisetyenziselwa ukuthutha ulwelo okanye igesi, esetyenziswa njengeebheringi zokuqhuba, kwaye isetyenziselwa ukwakha izakhiwo eziqinileyo.
Umgangatho wesigqeba sangaphandle se-Q345B ipayipi yensimbi engenamthungo yi-gb709 kunye nomgangatho wangaphakathi wesigqeba yi-GB / t1591-94.
Indlela yokubiza amagama iyafana ne-Q345B.
Ngenxa yokuphunyezwa komgangatho, olu hlobo lwentsimbi luvumelekile ukuba luhanjiswe ngokunyamezela okubi.
Umbhobho we-Q345 ongenamthungo luhlobo lwempahla yentsimbi yombhobho. Q imele isivuno sesi sixhobo. I-345 elandelayo ibhekisela kwixabiso lemveliso yale nto, malunga ne-345. Ixabiso lemveliso liyancipha ngokunyuka kwezinto eziphathekayo.
Q345A, akukho mpembelelo;
I-Q345B, i-20 ° impembelelo yeqondo lokushisa eliqhelekileyo;
I-Q345C, impembelelo ye-0 degree;
I-Q345D, yi-20 degree impembelelo;
I-Q345E yi - impembelelo ye-40 degree.
Kumaqondo obushushu eempembelelo ezahlukeneyo, amaxabiso eempembelelo nawo ahlukile.
I-Q345A, i-Q345B, i-Q345C, i-Q345D, i-Q345E, Lo ngumahluko wamabanga, omele kakhulu ukuba ukushisa kwempembelelo kuyahluka.
I-Q345B ipayipi yensimbi engenamthungo luhlobo lwezinto zentsimbi, ezinokuthi zihlulwe zibe yi-Q345A, i-Q345B, i-Q345C, i-Q345D kunye ne-Q345E ngokwebakala. Into abayimelayo kukuba ukushisa kwempembelelo kuyahluka. Q345A, akukho mpembelelo; I-Q345B, i-20 ° impembelelo yeqondo lokushisa eliqhelekileyo; I-Q345C, impembelelo ye-0 degree; I-Q345D, yi-20 degree impembelelo; I-Q345E yi - impembelelo ye-40 degree.
Ihlelwa ngokwenkqubo yokuvelisa: umbhobho oshushu oqengqelekayo ongenamthungo kunye nombhobho obandayo oqengqelekayo ongenamthungo.
Ngokohlelo losetyenziso, kukho: umbhobho wentsimbi ongenamthungo wolwakhiwo jikelele, umbhobho wentsimbi ongenamthungo wokuhambisa ulwelo, umbhobho wentsimbi ongenamthungo kwibhoyila yoxinzelelo oluphakathi kunye noxinzelelo oluphantsi kunye nombhobho wentsimbi ongenamthungo kwibhoyila yoxinzelelo oluphezulu.
Ngezinto eziphathekayo: umgangatho ophezulu wekhabhoni wokwakhiwa kwentsimbi umbhobho wensimbi ongenamthungo, umbhobho wensimbi ophantsi ophantsi, umbhobho wensimbi ongenamthungo.
1. Umbhobho we-Structural seamless (GB / t8162-2018) ngumbhobho wensimbi ongenamthungo wesakhiwo ngokubanzi kunye nesakhiwo soomatshini.
2. Umbhobho wentsimbi ongenamthungo wokuthutha ulwelo (GB / t8163-2018) ngumbhobho wentsimbi ongenamthungo osetyenziselwa ukuthutha amanzi, i-oyile, igesi kunye nolunye ulwelo.
3. Umbhobho wentsimbi ongenamthungo webhoyila yoxinzelelo oluphantsi noluphakathi (gb3087-2018) yintsimbi yomgangatho ophezulu wekhabhoni eshushu-eqengqelekayo nebandayo etsalwa (eqengqiwe) esetyenziselwa ukwenza umbhobho womphunga oshushu kakhulu, umbhobho wamanzi abilayo kwibhoyila yoxinzelelo oluphantsi noluphakathi. , umbhobho womphunga oshushu kakhulu kunye nombhobho we-arch wezitena kwibhoyila ye-locomotive.
4. Umbhobho wentsimbi ongenamthungo kwibhoyila yoxinzelelo oluphezulu (gb5310-2018) yintsimbi yekhabhoni ekumgangatho ophezulu, intsimbi yealloyi kunye nentsimbi ekwaziyo ukumelana nobushushu engenamthungo esetyenziselwa ukwenza umphezulu wokufudumeza webhoyila yamanzi ngoxinzelelo oluphezulu nangaphezulu.
