Introduction to the milling technology with the bead mill ...

The actual dispersion system in a bead mill consists of a milling chamber and an agitator; the milling chamber is filled with the grinding beads (material e.g. glass, zircon oxide, steel) and the product to be dispersed. In the milling vessel, the grinding medium is kept moving by the agitator, which itself is driven by a motor. ...

Stainless Steel | Metal Casting Resources

Stainless steel can be cast or wrought. The main difference is in how it is formed into a final product. Cast stainless steel is made by pouring liquid metal into a molding container with a specific shape. Wrought stainless steel starts out at a steel mill, where continuous casters make stainless into ingots, blooms, billets, or slabs.

Intro to Continuous Casting - CCC - U of I

Over 90% of commercial aluminum alloys are cast by semi-continuous vertical casting machines, typically as 0.05 - 0.5m diameter round sections. This process is similar to steel continuous casting, with the significant difference that it must be stopped periodically when the bottom of the cast "ingot" reaches the floor of the casting pit.

Basics of Continuous Casting of Steel - Cast Iron Casting ...

Continuous casting, also known as strand casting, is the process where a metal is heated until it liquefies. The molten metal is then allowed to solidify until it becomes a semi-finished slab that is later rolled in the finishing mill. It is used to cast metals of uninterrupted lengths.

Tolerances | Industrial Tube and Steel Corporation

Round bars are made with sufficient stock on the outside diameter to guarantee clean-up at the nominal dimensions. Stock allowance is a function of the bar diameter. Example: 3.00" + 0.118" = 3.118" tolerance is +/- 0.030" Max size = 3.148 Min size = 3.088. A 3.000" bar is guaranteed to finish at 3.000".
