6-High Rolling Mills. Six-high rolling mills are the similar to 4-high rolling mills however, they have work rolls, intermediate rolls, and back up rolls. Refer to Drawings (right), which shows a 6-high reversing mill for rolling light gauge steel. The intermediate rolls can be adjusted horizontally to prevent edge drop, which means the edge ...

sulfite pulp mills because it resists sulfuric acid compounds. Its use has been broadened, however, to handling many chemicals in the process industries. Type 317 contains 3-4% molybdenum (higher levels are also available in this series) and more chromium than Type 316 for even better resistance to pitting and crevice corrosion.

Mini Mills: Obtains most of its iron from scrap steel recycled from used automobiles and equipment or by-products of manufacturing. Material is melted in an Electric Arc Furnace (EAF). Material is continuously cast from the laddle into a slab form and while still heated is rolled to a final sheet product.

A #4 finish is a straight-grained finish commonly thought of as 'brushed' finish, as are #3 and #6 finishes. A standard #4 finish could be about 0.8 (32) Ra, while a #4 Dairy or Sanitary finish have an roughness average between 0.3 (12) Ra and 0.4 (16) Ra. Two other finishes; #7 and #8 are buffed. The surface of #8 is very nearly flawless.

These backup rolls are larger and contact the back side of the smaller rolls. 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.

Thus, the yield strength of cold rolled steel is higher than that of hot rolled steel. As an example, a hot rolled steel product may have a yield strength of 235 MPa. In comparison, a cold rolled steel product with the same chemical composition has a yield strength of 365 MPa. The main advantages of cold working are: Accurate finished dimensions.

nin) by bleaching; and 4) paper formation and manufacture. A typical layout of a mill using the kraft chemical pulping process is shown in figure 2-1. Mechanical, semichemical, and sulfite pulp mills differ in detail, particularly in wood preparation, fiber separation, …

NOTE: Hot-rolling and cold-rolling should not be mistaken for different grades of steel. Steels of different grades can be produced as hot-rolled or cold-rolled. HOT-ROLLED STEEL. Hot-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.

Basic differeneces between hot rolled steel and cold rolled steel Theoretically, the only difference between hot rolled and cold rolled steels is that hot rolled steel is rolled to its final dimensions while hot enough to scale (over about 1700 degrees F) while cold rolled steel is rolled to its final dimensions well below scaling temperatures.

The heart of the temper mill is the cold rolling mill stand which produces the temper pass. It will include electric powered drive motors and speed reduction gearing suited to the process desired. The design of the rolling mill can be a 2-high or 4-high (even 6-high in some cases). The mill stand can be work roll driven or back up roll driven.

A high-grade machine finish, which needs close control. It is relatively easy to produce with cylindrical, centerless, or surface grinders. It is also preferred for products that do not require continuous motion or large loads. 0.4: 16: High-quality surface are often produced using emery buffing, lapping, or coarse honing.

Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.
