E355 Din2391 H8 Bks Srb Lub tog raj kheej yeeb nkab
E355 DIN2391 H8 BK+S SRB lub tog raj kheej yeeb nkab yog qhov siab -kev ua tau zoo honed raj tshwj xeeb tsim rau kev siv hydraulic kheej kheej. Ua raws li DIN 2391 tus qauv, lub raj no ua kom muaj qhov tseeb tshwj xeeb, cov khoom siv kho tshuab, thiab qhov zoo ntawm qhov chaw, ua rau nws tsim nyog rau kev xav tau kev lag luam ib puag ncig.

E355 DIN2391 H8 BK+S SRB lub tog raj kheej yeeb nkab yog qhov siab -kev ua tau zoo honed raj tshwj xeeb tsim rau kev siv hydraulic kheej kheej. Ua raws li DIN 2391 tus qauv, lub raj no ua kom muaj qhov tseeb tshwj xeeb, cov khoom siv kho tshuab, thiab qhov zoo ntawm qhov chaw, ua rau nws tsim nyog rau kev xav tau kev lag luam ib puag ncig.
Cov khoom siv E355 (sib npaug rau ST52) yog ib qho tsis yog - alloy zoo hlau paub txog nws lub zog zoo thiab tawv. Nws cov tshuaj muaj pes tsawg leeg suav nrog cov qib tswj cov pa roj carbon (tsawg dua lossis sib npaug li 0.22%), silicon (tsawg dua lossis sib npaug li 0.55%), thiab manganese (tsawg dua lossis sib npaug li 1.6%), nrog rau cov ntsiab lus phosphorus thiab sulfur tsawg (tsawg dua lossis sib npaug li 0.025%), uas ua rau zoo weldability thiab formability. Txoj kev xa khoom BK+S qhia tias lub raj txias - rub thiab kev ntxhov siab - tau txais kev cawmdim, txhim kho nws cov khoom siv kho tshuab. Qhov no ua rau lub zog tensile yam tsawg kawg nkaus (Rm) ntawm 600 MPa, yield zog (ReH) ntawm 520 MPa, thiab elongation (A5) tsawg kawg yog 14%, xyuas kom durability thiab tsis kam mus deformation nyob rau hauv siab siab.
Sab hauv txoj kab uas hla ntawm H8 lav qhov kev tswj xyuas qhov tseeb, qhov tseem ceeb rau kev sib khi zoo thiab kev txav piston du. Lub raj tau dhau los ua SRB (Skived thiab Roller Burnished) ua, uas xa cov ultra- du sab hauv nto nrog roughness ntau ntawm RA 0.1–0.4 μm. Qhov no txo qis kev sib txhuam thiab hnav, ncua lub neej foob, thiab txhim kho tag nrho lub tog raj kheej efficiency.
Muaj nyob rau hauv cov kab uas hla ntawm 40 hli mus rau 480 hli thiab ntev mus txog 12 meters, cov hlab no tau dav siv nyob rau hauv hydraulic systems rau kev tsim kho machinery, txhaj tshuaj molding khoom, cranes, thiab lwm yam hnyav - daim ntaub ntawv. Kev sib xyaw ua ke ntawm cov khoom siv zoo tshaj plaws, kev tsim khoom raug, thiab kev kho saum npoo av ua rau E355 DIN2391 H8 BK+S SRB lub tog raj kheej lub tog raj kheej xaiv kev ntseeg siab rau siab -kev ua haujlwm hydraulic kheej kheej.
