Sheet metal descaling system for hot rolling mill plant

We have created an entire descaling plant for a customer steel mill, an international leader in sheet metal manufacturing.. The descaling system has a fundamental function inside a hot rolling mill plant: it eliminates the slag or the surface calamine present on the metal by projecting metallic grit. In addition to superficially cleaning the sheet metal, the descaling system, equipped with 600 ...

The Hot Rolling Process - California Steel Industries, Inc.

The workhorse roughing mill has 135” wide rolls for rolling ‘broadside’ (as the first roughing mill is commonly called) to make a slab wider. A 5,000 hp motor drives 42”-diameter work-rolls through 28:1 gears to reduce the slab’s thickness by as much as 2-½”. The last four roughing mills each incorporate edgers for width control and roll the bar from five to six inches thick ...

Hot rolling

The base material demand of the Hot Rolling Mill is met by self-produced and imported slabs. Before being rolled into sheet, the slabs are heated to the temperature required for hot forming (1200 - 1270 °C) in two suitable pusher type furnaces operating with sliding rails (fired by a mixture of any ratio of natural gas and coke oven gas) and in one natural gas-fired walking-beam furnace. The ...
