Txhawm rau txo cov nqi tsim khoom, qee lub tuam txhab siv hlau packers hauv steelmaking nroj tsuag. Lawv yuav tsum tau nce tus nqi tso zis ntawm cov hlau packers thiab ua kom cov pace ntau lawm. Cov roj kub hauv cov roj tank ntawm cov packers tau nce siab, qee zaum ncav cuag li 72 degree, uas ua rau kev tsim khoom tsis txaus siab. Nyob rau hauv qhov kev pom ntawm qhov teeb meem uas cov roj kub ntawm lub hydraulic system ntawm cov hlau packer yog siab dhau lawm, qhov teeb meem technical tau raug daws los ntawm kev saib xyuas cov ntaub ntawv tseem ceeb, zom cov txheej txheem kev khiav hauj lwm ntawm cov khoom siv txawv teb chaws, tshawb xyuas thiab kawm.
