Kev piav qhia
Tundish nozzle los ntawm ZhenAnyog ib feem tseem ceeb ntawm kev nruam casting ntau lawm. Molten steel ntws los ntawm tundish mus rau hauv lub crystallizer los ntawm lub tundish nozzle.Nyob rau hauv cov txheej txheem no, lub qhov hluav taws xob qhov hluav taws xob yuav eroded thiab widened, tus nqi ntawm molten steel nyob rau hauv chav tsev lub sij hawm yuav nce, thiab cov nto ntawm molten hlau nyob rau hauv lub pwm yuav nce, yog li nws yog ib qho tsim nyog los txhim kho qhov nrawm nrawm kom zom cov hlau molten ntau dhau.
