Rolling Bar Mill Processes And Operations

Metal production specialists use a host of techniques to fabricate custom-made parts, fittings, and other industrial and commercial products. Each process creates an absolutely unique product with specific attributes. The various techniques and processes like bar milling, sheet metal fabrication, etc. serve specific purposes. This article focuses on the rolling process.

Rolling accounts for around 90 % of all materials formed by metalworking process. Hot Rolling is performed at the elevated temperature above the re-crystallization temperature. In this phase, the coarse-grained, fragile, and permeable structure of the continuously cast steel is broken down into a wrought structure having finer grain size and enhanced attributes.

Rolling Bar Mill Process

Rolling bar mill process is used to recast a bar into a specific shape, form, and length to make it fit varied jobs and specifications, the same as running a router or shaper down a narrow length of wood. In this process round or square bars are taken to shape them into hexagonal or angled bars, adding grooves or other features down the entire length. It can also be produced by using different materials like brass and stainless steel. To create each shape, the specialist puts together a series of cutters that could be bevels, round overs, slots, or some other. In the end, it is milled down to a smooth surface and formed into the proper dimensions.

Basically, a rolling mill comprises a set of roll stands as well as an array of equipment that perform both rolling and auxiliary operations. The process begins by transferring the steel material to be rolled from the stock to the reheating furnace. Here it is heated to the rolling temperatures.

Rolling Bar Mill Operations

The diverse tasks being completed in a rolling bar mill plant comprises of (I) rolling of the heated steel material in the mill, (ii) shifting of the material under rolling from one roll stand onto the next, (iii) turning or twisting and shearing of the material in case of certain mills, (iv) transporting the steel product after rolling, (v) cooling the rolled material on cooling bed in certain mills, (vi) cutting, marking or stamping of the rolled product, and (vii) trimming, packing, and transport to the stock of finished product.

Conclusion

The rolling process is a standard technique used in various industries to produce the exact item you need.
