Abstract—The cooling of a metal during heat removal via radiation and convection is considered. The cooling beds used in modern section rolling mills are calculated using the quantity of heat transfer. A formula is proposed for calculating the time of metal cooling from 850 to 50°C. It gives a result 1.78 times less than the formula that …

To remove the heat from the roll, cooling water is applied. The difficulty in the removal of the heat from the roll is the result of two factors. ... If a mill rolls 800,000 tons per year using billets of 1.25 ton weight, it rolls 640,000 billets per year. That is 639,999 billet gaps. If the average billet gap is 5 seconds that is (5 sec x ...

1. Temperature Control. The primary role of roll cooling is to manage the temperature of the rolls. This ensures that the steel remains within specified temperature ranges, preventing overheating and maintaining product quality. 2. Roll Protection. …

Roll cooling serves several critical functions in a rolling mill: 1. Temperature Control. The primary role of roll cooling is to manage the temperature of the rolls. This ensures that the steel remains within specified temperature ranges, preventing overheating and maintaining product quality. 2.

Gupfenstrasse 5. Uzwil. 9240. Switzerland. 's roller cooling system upgrade for three-roll mills such as the SDV, SDW and SDX machines, includes a closed, integrated cooling system with an optional monitored water tank.

In this 18-roll stand, the very thin rolls are supported against lateral buckling. With the 18-HS mill design, high-strength and stainless steel grades can be produced more efficiently. Integrated in a continuous tandem cold mill, our 18-HS allows you to set up a full, continuous production route for stainless steel.

The combination of roll gap cooling, roll gap lubrication and improved exit side cooling systems reduces the roll temperature. This results in a thinner oxide layer on the roll surface with less work roll peeling as a result. ... Traditionally, the most important factor is the evolution of the profiles of the rolls in the mills caused by their ...

Since the cooling water between rolls or stands is widely used in the hot rolling process, the supply of lubricating oil needs to ensure that the lubricating oil is evenly distributed on the roll surface and cannot be washed away by the cooling water. There are three main supply modes of hot rolling lubricating oil (Fig. 1). Pre-mixing mode.

Cooling sections at rolling mill should be designed considering both aspects. Numerical modelling of the thermal behaviour of rolls during rolling can be done with good accuracy. The level of knowledge of numerical methods for heat conduction in a roll and level of computers can make this problem a routine task.
