This process gives steel a higher strength-to-weight ratio than can be made on a hot mill. A modern five-stand tandem cold mill may receive a sheet about 1/10 inch (0.25 cm) thick and 3/4 of a mile (1.2 km) long; 2 minutes later that sheet will have been rolled to 0.03 inch (75 mm) thick and be more than 2 miles (3.2 km) long.

Measuring 72 inches wide, 20 inches deep, and 37.5 inches tall, this 12-drawer rolling workbench weighs 317 pounds. It is not lightweight at all, which is not surprising given that it is made from heavy-duty steel. It does come with four 5-inch wheels, two of which are locking to keep the workbench stable.
High casting speeds in the range of 2 m/min to 4 m/min and width of 800 mm to 1600 mm is possible. The caster is connected to rolling mill via a roller hearth reheating furnace which equalizes the slab temperature to 1120 deg C. The rolling mill can include four, five, or six finishing stands depending on product mix and required finishing gauge.
The rolls of F#5 stand of the Thin Slab Caster Rolling (TSCR) mill failed during operation. Visual observation of the failed component is shown in Fig. 2a–c which indicates that the fracture line had initiated from the outside and spread over the whole cross section starting from the filet area. The closer view of the fracture surface showed ratchet marks on the …
The EJ201 and EJ202 engines had an aluminium alloy cylinder head with cross-flow cooling. Unlike the EJ20 engine, the intake ports for the EJ201 and EJ202 engines created a 'tumble swirl' motion for air as it entered the cylinder for better mixing of the air and fuel for more uniform flame travel and faster combustion.
The top guide was supplied assembled; complete with roll cooling and descale nozzles for direct installation into the mill! Units were supplied for the mill entry, mill exit and a spare unit. On a 4 hi rolling mill stand, the roll stack has two backup rolls and two work rolls.
