Nowadays, the working scope of the hot rolling mill is to use pressure rollers with a large number of specifications to gradually reduce the wheelbase of the mirror wheel. Finally, the laminated metal blank and coil are strongly extruded in various types of square steel and angle steel. It is made of scrap iron, iron and cast iron and made of several thin steel plates with different thickness. As the initial raw material of the hot rolling mill, the circumference of the pipe is used to determine its circumference, and the size is actually the width of the thin iron plate to be used.
In the cutting machine, the rotating shaft that rolls up and groups the iron and is installed at the end of the hot rolling mill is cut off, and the conductor plate iron is extracted through the forming guide rail. The semi closed chassis passes through the first group of mirror rollers of the hot rolling mill. After being compressed by the rollers in a special way, some rounded corners are rolled up around the original flat and thin iron sheet. The cold rolling mill is a device for metal rolling process, which refers to the vehicle of complete sets of equipment.
This kind of equipment mainly includes computers, auxiliary equipment, lifting and transportation equipment and the whole production process, and the equipment to realize the metal rolling process. It refers to the rolling of complete sets of equipment, including the main equipment and auxiliary equipment, and the whole production process of lifting and auxiliary equipment of transportation equipment. However, the so-called mill is usually only referred to as the main equipment, and the rolling is alternately wound from the upper and lower hollow rollers to the left or right.
It is usually used in steel mills and track hot rolling mills. The rolling mill has been replaced by an efficient two high rolling mill. The working roll has a small diameter, transmits rolling torque, and the rolling pressure is received by the large-diameter support roll. The advantage of the rolling mill is that it has high relative stiffness, is the rolling of large pressure, and can roll thinner steel strip. It has reversible and continuous cold rolling. It is widely used as plate cold rolling mill with hot rolling mill or cold rolling mill and flat mill, Rolled parts are plastically bent around small idling rolls and can roll up metal and alloy strips that are difficult to deform.
