What do steel mills and levelers do respectively?

Steel rolling: hot rolling and cold rolling.

Hot rolling: that is, the billet or ingot is heated to a red-hot state and rolled by a rolling mill into steel products with different cross-sectional shapes that can be used.

Cold rolling: usually, under the condition of no heating, the hot rolled blank is pressed into a thinner and smoother surface plate with the rollers of a rolling mill at room temperature.

Straightening: Straightening or leveling steel with straightening equipment.

About Rolling Operators and Straightening Operators

1。 If the traditional rolling mill is mechanized semi-mechanical manual or mechanical steel feeding, operate the input and output roller table of the rolling mill or manually feed the billet into the rolling mill. Or send the rolled steel to a straightener for straightening. If it is a regulator, it is also responsible for adjusting the working state of the machine to produce qualified products.

2。 If it is a modern fully automatic computer control, everyone looks at the screen and presses the button in the control room.
