peb khaws cov khoom zoo, tus nqi sib tw, ntau txhiab tons ntawm cov khoom lag luam, kev xa khoom zoo tshaj plaws thiab kev koom tes txhim khu kev qha rau cov neeg siv khoom thoob ntiaj teb. Peb tau koom nrog kev lag luam steel rau ntau tshaj 20 xyoo, kev pabcuam zoo tshaj plaws thiab tus nqi sib tw tshaj plaws yog ib qho ntawm peb qhov zoo tshaj plaws uas ua rau peb niaj hnub no!
Cov pa roj carbon steel kauj yog tsim los ntawm cov slabs (feem ntau yog nruam nruam slabs), uas yog rhuab thiab ces ua rau hauv strips los ntawm roughing thiab xov mills. Qhov kub steel sawb los ntawm lub xeem tiav zeb yog txias rau qhov kub thiab txias los ntawm laminar ntws thiab dov rau hauv coils los ntawm ib tug coiler. Cov coils txias yog ua tiav rau hauv cov ntawv hlau, tiaj tus coils, thiab cov khoom siv slit strip los ntawm cov kab sib txawv raws li qhov sib txawv ntawm cov neeg siv khoom.
