Level control of blooms before descaling Proxitron
Customer problem. The end user needs to check if the bloom head is bent to avoid damage of the subsequent descaler. As blooms of different heights are transported, also control lines (light barriers) at different heights are necessary.
Highspeed data acquisition system speeds up commissioning ...
In the case of high speed sections of the process such as the shear, pinch roll and the laying head for rod mills, it is absolutely es sential to have a system to monitor and record at high speeds. Many rolling mills use meters on the desk to monitor stand tension and ad .

Wear of Laying Head Pipes in a Wire Rod Mill | SpringerLink
May 29, 2013· Abstract. The failure analysis on the premature wear of a "Laying Head Pipe" in a Wire Rod Mill has been presented. The hotrolled wire rods subsequent to finish rolling pass through the "Laying Head Pipe" which rotates and lays the wire rods in the form of coils for air cooling to achieve the final properties.
How (And When) To Use A Jewelry Rolling Mill
What is a rolling mill? A rolling mill is a tool used to apply pressure to metal to flatten and lengthen it. Each machine has differences, but these are the basics components: a tightening screw, rollers, and a crank. The rollers on jewelry rolling mills may be half flat and half grooved. The flat side is for sheet, the grooved is for wire.
The Additional Processing Steps in the Manufacture of Cold ...
The coldreduced coil, as it exits, is very hard and possesses very limited applicability. It is very stiff and exhibits high amounts of springback when bent. Therefore, this steel must be annealed (heated to high temperatures) to soften it, and make it useful.
Advanced Process and Quality Control in Hot Rolling Mills ...
Defects stem from a variety of causes such as poor billet quality, worn rolling mill parts, and process malfunctions. Detectable defect types are many and include shells, cracks, pinholes, scabs, inclusions, laps and overlaps (Figure 2), as well as repetitive defects ECNDT 2006 .
HOW BALL MILL WORKS?
Oct 10, 2016· Pic. 3. Pipe ball mill. The balls impact on the milled material longer at the pipe ball mills. The drum of these mills lined with flint blocks inside or flint pebbles on the cement. Material continuously fed by the drum axis through a hopper at one end and leaves at the opposite end of the drum through end wall or holes on drum walls. Pipe ball mill (Pic.
Manufacturing Process Routes for Reinforcing Steels
A rolling mill consists of a series of stands, each of which consists of two cylindrical rolls into which grooves are cut to accommodate the material being rolled. The sizes of the grooves are progressively reduced through the mill, so that the crosssectional area of the product is continuously reduced as it is rolled. Hot rolling is a constant volume
Metal Rolling Manufacturing Process
Figure:144. It is known, in metal rolling practice, that the amount of roll force is reduced with a smaller radius of the rolls. Smaller radius rolls, however, deflect easier and must be supported by other rolls. The four high mill uses this principle with two smaller work rolls each supported by a larger backing roll.
Rolling Mill Rolling Mill Cooling Bed Hani Tech
Rolling Mill Cooling Bed is mainly used for slow natural cooling plate line after rolling. In the structure steel production line, Rolling Mill Cooling Bed also has a precurved function to prevent the merchant steel in the natural cooling process due to different quality lead to the irregular bending.
