The Rolling Mill accepts the slabs arriving from the tunnel furnace, rolls them to the proper thickness or gauge to meet the customer's order, and sends them through the runout table cooling water sprays to the coiler, where they are wrapped in a spiral to form coils.

The roughing mill is made up of six independent rolling mill stands, the last four of which incorporate small vertical rolling mills called edgers. Slabs heated in the furnace until they glow bright orange-yellow are rolled through one stand at a time to produce so-called transfer bars suitable for finish rolling. High-pressure water-jet

Thread Rolling Figure 13.16 (a) Features of a machined or rolled thread. (b) Grain flow in machined and rolled threads. Unlike machining, which cuts through the grains of the metal, the rolling of threads causes improved strength, because of cold working and favorable grain flow. Figure 13.15 Thread-rolling processes: (a) and (c) reciprocating

The cold rolling mills use the motor to drag the reinforcement, and the load-bearing roll and working roll of the cold rolling mill jointly apply the force to the two surfaces of the reinforcement. By changing the gap between the two rolls, the purpose of rolling cold-rolled ribbed bars with different diameters is realized.

These slabs are inspected, scarfed and then reheated in slab reheating furnace to the rolling temperatures before being rolled to hot rolled coils in a semi continuous or continuous hot strip mills. Development of thin slab casting and rolling (TSCR) technology is a step forward to reduce the number of process steps in the production of hot ...

A method for reducing the thickness of a slab of metal under conditions which tend to cause alligator defects to occur. The method comprises the steps of directing a relatively thick slab of metal several times through a rolling mill or mills to incrementally reduce the thickness of the slab until the thickness approaches a value that tends to produce a longitudinal and lateral …

In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change in its cross-sectional area.. The types of rolls used in rolling mills are depended upon the shape, size and the gap between the rolls and their contour. Because of workability and limitations in …

Rolling speeds at the finishing mill will be higher than at the roughing mill. Hence rolling cannot be done with stock present in both roughing and finishing mills. Finishing mill rolling of reheated slab: The finishing mill usually has five to seven finishing roll stands, which reduce the thickness of the transfer bar down to the gauge required.

Hot rolling takes advantage of the metal's ductility at high temperatures to execute great section reductions. Flat product hot rolling mills are fed from flat slabs, previously heated and homogenized in reheating furnaces in order to achieve suitable temperatures for the subsequent transformation process.

Some ingots are sent directly to a universal plate mill for immediate rolling of steel plates. Most ingots, however, are sent to semifinishing mills (also known as slabbing or blooming mills) for reduction and shaping into slabs, blooms, or billets.
