Solutions for hot rolling mills.

Disadvantages of hot rolling: 1Expensive process: hot rolling is an expensive process because it requires expensive tools great skill to handle and maintain itCorrect temperature difficult to maintain: the correct temperature range for working is difficult to maintain.

Endless hot strip rolling processIn conventional hot strip production slabs of thickness of about 250mm are heated in a furnace and are reduced to 30 to 60mm in thickness after passing through the roughing mill and then further reducing it to within a range of 04mm by rolling in the finishing mill.

Find here manufacturerssuppliers and exporters of hot rolling mills along with complete detailsThese mill are widely used to produce sheet metal or simple cross sections such as rail road bars from billets– a free powerpoint ppt presentation displayed as a flash slide show on powershow.

Hot rolling begins with heating the billet or blooms to a high temperature of around 1100 degrees celsiusThe temperature is of particular importanceHot rolling and hot extruding drawing involves working above the recrystallization point of the steelThe mill passes the heated material through a variable number of stands.

Hot rolling the first hot-working operation for most steel products is done on the primary roughing mill blooming slabbing or cogging millsThese mills are normally two-high reversing mills with 04 m diameter rolls designated by size.

In this paper a real application of opti- mal control of a hot rolling mill is presentedIt is used the state space model formulation in the minimization of the strip thickness variations.

Hot rolled production.

It also should optimize the number of passes required for rolling to reduce the total rolling time cycle with minimum time spent for changing and adjustment of rollsDetermine the location of neutral point for flat rollingNeutral point is the point along the contact length where velocity of the strip equals velocity of the roll.

Hot steel rolling.

Jul 01 2007 this paper considers some of the control issues in hot rolling millsHence to set the context first we give a brief description of a typical processThe role of a hot strip mill process is to roll the slabs produced in a continuous casting process and produce strips of thickness 01 shows a typical layout of a hot strip mill.

Bar and wire rod mills sms group.

Most primary rolling is done in either a two high reversing mill or a three-high continuous rolling millFinal products from hot rolling include plates strips and a wide variety of bars and sectionsPlates and strips are normally rolled between two plain cylindrical rolls or on four-high mills.

Note: hot-rolling and cold-rolling should not be mistaken for different grades of steelSteels of different grades can be produced as hot-rolled or cold-rolledHot-rolling refers to a mill process in which you roll the steel at a temperature above its recrystallization temperature; a heat that typically exceeds 1000 f.

Rolling is one of the key processes in metal manufacturing but there are two ways to ‘roll’ steel: hot rolling and cold rollingIt is a common misconception that these processes relate to a metal’s specification or grade; instead they refer to how a metal is processed at the mill.

What is hot rolling.

Ppt – what is the hot rolling mill? powerpoint.

These rolls can either be flat or grooved contoured for the hot rolling of rods or shapesUnder these conditions the rolls grip the piece of metal and deliver it reduced in cross-sectional area and therefore increased in lengthX the initial hot-working operation for most steel products is done on the primary roughing mill blooming.

This process is vastly used in respect of any other rolling processIn this process the metal is heated above the recrystallization temperatureIn the hot working process the metal is changing its grain structure because of the heat now there were a new set of strain-free grains in the metal and this process needs less amount of force which correspondingly reduces the quality of the.
