Kev tsim cov txheej txheem rau Railway Tie Phaj
Rail khi daim hlau, cov khoom tseem ceeb hauv kev tsheb ciav hlau fastening, yog tsim los ntawm ntau txoj kev, suav nrog casting, forging, thiab dov. GNEE Rail, lub tuam txhab ua lag luam rail fastener, ntiav cov cuab yeej siv dov los tsim cov ntawv khi, ua kom zoo nrog Q235 carbon steel, paub txog nws cov ntsiab lus carbon nruab nrab thiab cov khoom zoo ntawm lub zog, plasticity, thiab weldability. Casting, ib txoj hauv kev, siv QT400-18 carbon steel rau nws cov weldability, machinability, thiab cuam tshuam toughness. Forging, lwm txoj kev tsim khoom, suav nrog cov hlau cam khwb cia dawb lossis Q345 carbon steel, nyob ntawm cov kev xav tau tshwj xeeb. GNEE Rail muaj cov kev pabcuam kev cai kom tau raws li cov neeg siv khoom xav tau, tso cai rau kev hloov kho ntawm khi phaj qhov ntev.
