Mechanical Engineering questions and answers. Multiple choice. Select only one true alternative. You are in charge of a rolling mill that has two lines, one is a two-high rolling mill with a small maximum force capacity of 100 kN (on one roll) and the other is a cluster (Sendzimir) type rolling mill with a force capacity of 5 MN (on one roll).

Heretofore, high reduction rolling using unsupported (two high) small diameter rolls (less than at least 30.5 cm (one foot) in diameter) has not been commercially practical. U.S.-A-4,218,907 describes a two high mill which provides operating characteristics only achievable previously with four high mills.

A four-high mill has four rolls, two small and two large. A cluster mill has more than 4 rolls, usually in three tiers. These types of mills are commonly used to hot roll wide plates, most cold rolling applications, and to roll foils. Historically mills were classified by the product produced:

The rolling experiment at both room temperature (RT) and at cryogenic temperature was performed on a two-high rolling mill with the roll diameters of 120 mm. The change of contact length to mean thickness ratio (L/h), calculated by Eq., is shown in Fig. 1 for the current rolling schedule.

Tags Pickle Lines, Rolling Mills; Temper Pass or Skin Pass Rolling. Material can be reduced accurately while skin passing. Hot rolled steel coming from a steel mill or pickle line may need to be reduced 1% to 2% in thickness. This can be done on a coil-to-coil temper pass mill or in line on a cut-to length line.

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

Two High Rolling Mill: This mill consist two rollers arranged as shown in figure. Both the rollers rotate in opposite direction for desire movement of work piece. Work piece is feed between the rollers which apply a compressive force and tends to plastically deform work piece and convert it into desire shape.

Rolling mill stands are historically made as a steel casting but today many are fabricated from cast slabs or rolled plate. The cross section of the post is measured in square inches (mm 2) which determines the housings separating force. Rolling mill stands can be designed as 2 high, 3 high, 4 high, 6 high or 20 high roll configurations.
