Peripherally Drilled Rolls or Centrally Cored Rolls

Do you use centrally cored rolls or peripherally drilled rolls in your two-roll mixing mills? Or a combination of both? Roll selection for a mixing mill is of decisive importance for the quality of many high-tech products manufactured by the rubber industry. Open two-roll mills in rubber processing are recommended when quick cooling for the batch being

A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING

Especially I am waiting for results from "roll cooling simulation" to give my theory of fire-cracks more background. Secondary scale on hot strip and the impact on wear is another issue. Stresses from Hertzian pressure in 4-high cold mill back up rolls were measured years ago, the results were never published, but of high interest also, maybe later. K. H. Schröder July 2003 K. H. Schröder

white paperSuccessful Execution of Roll Cooling Strategies

In summary, in most mills the primary surface to target is the work roll. Which side of the mill should one be cooling? The determination of which side of the mill to cool depends upon the overall mill design and cooling strategy. In the typical hot mill, cooling is generally done on both sides for several reasons.

Cooling Roll Coolant Systems Bijur Delimon

Cooling Roll Coolant Systems The primary functions of Roll Coolant Systems on either Hot or Cold Steel or Aluminium Rolling Mills is to lubricate the surface of the metal and to remove the heat induced by the reforming of the metal. However, the treatment of the coolant before application and the dispersement of the coolant onto the product are of prime importance in the quality of the final

Roll Cooling – Heat Transfer and Fluid Flow Laboratory

The Heat Transfer and Fluid Flow Laboratory designs cooling of rolls to reach their long working life while rolled product is still well heat treated. There are a few aspects of concern that are reflected when roll cooling is designed by the lab. Especially, wearing of rolls where high temperature decreases the durability of the surface layer

The Hot Rolling Process California Steel Industries

The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.

Mill coolant system design thefabricator

15/05/2001· Baffles, perforated steel, wire mesh, roll media, and submersed conveyors are used individually or together to remove large impurities from the coolant before it is sent from the mill (preferably by gravity) back to the reservoir. Particle size can be measured using a variety of methods so that removal of the contaminant can be cross-referenced

Work roll thermal expansion control in hot strip mill

Work roll thermal expansion (crown) plays an important role in controlling strip profile and flatness of the strips. This can be done with a perfect and controllable cooling system which also takes care of the work roll against damage induced by fire cracking.

27/11/2015· Understanding Rolling Process in Long Product Rolling Mill Rolls and roll pass design. Rolls are the tools of the rolling mill and are the costliest consumable in a rolling mill. The way the rolls are used to execute their duty of deforming steel is in many cases largely determined by the roll pass design. The purpose of the roll pass design is (i) production of correct profile within
