High definition Two Roll Straightening Machine - Roller Table – Runxiang

The roller table is the main equipment for transporting rolled parts in the rolling mill, and its weight accounts for about 40% of the total weight of the whole rolling mill equipment, which is the most used equipment in the rolling mill. Rolling parts in and out of the heating furnace, reciprocal rolling on the mill and after rolling transport to the finishing process are completed by the roller conveyor.

The roller table is a transportation equipment that uses the rotation of the cylindrical rolls to convey the rolled parts. It links the various processes of the rolling production process with each other. Realize the mechanization of operation, greatly improve labor conditions, improve production efficiency, and provide conditions for the realization of automated operation. Rolling shop roller weight accounts for about 40-60% of the weight of the shop equipment.

In the strip hot strip mill using a number of rolls, they are divided into a number of sections, each section of the rolls either independently or with the rolls to synchronize the speed and direction of the delivery of rolling parts.

In order to enable the rolls to run in the center of the rollway, the use of drum-shaped rolls, and alternately make the left and right sides of the horizontal plane slightly inclined, or so that the axis of the rolls and rolls running in the direction of the alternating angle than the right angle slightly skewed some.

In particular, the output roller table, the past more than the method of alignment, but recently there is a tendency to reduce the roll spacing, and thus the use of an oblique roll arrangement is reducing the rolls. This is in order to roll the thin specifications of the strip to avoid making the strip in the rollway due to the high final rolling speed and cause folding. In addition, the speed and roll diameter of the rollway should be fully considered.

For the middle valve rollway, in addition to the requirements of alignment, in order to fine rolling population temperature control, the requirements of the rolls can be reciprocating movement in the middle of the rollway, and in order to improve the speed control accuracy of the final stand roughing mill and finishing mill, the previously common collective drive is being replaced by a separate drive.
