(1) When the slab heating system is unreasonable or the heating operation is poor, it is difficult to remove the iron sheet once, and it is pressed onto the surface of the steel sheet during rolling. (2) The setting of the large vertical roller is unreasonable, and the iron sheet is not loose and difficult to remove. (3) Due to the low water pressure of the high-pressure descaling water pipe, the water nozzle is blocked, the angle of the water nozzle is incorrect, and the original garden is used improperly, so that the iron sheet on the steel plate is not removed, and is pressed onto the surface of the steel plate after rolling. (4) Iron oxide scales occur more in boiling steel, and red iron sheets are easily produced in steels with higher silicon content. Medical Gloves are disposable gloves used
