removed with high-pressure water immediately before the steel goes into mill stands At high temperatures, however, carbon steel is oxi- dized so quickly that, even when scale is removed, the steel is reoxi-dized immediately and rolling is always done on steel covered with scale The existence of scale during hot rolling between steel and rolling rolls.

HPGR or high-pressure grinding rolls have made broad advances into nonferrous metal mining. The technology is now widely viewed as a primary milling alternative, and there arc a number of large installations commissioned in recent years. After these developments, an HPGR based circuit configuration would often be the base case for certain ore ...

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

The rolling process is shown in Fig. 2.1: 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.

The impact toughness of rebars produced by the THERMEX process and ordinary rolling process was investigated by the Charpy impact test at temperatures between-40 0 C and 100 0 C.

In the process of Rolling the most significant aspect is the generation of heat through friction and deformation in the roll bite and in a typical Cold Tandem Mill, work roll temperatures normally fall in the range of 55oC – 70oC with strip recoil temperatures and inter-stand strip temperature rarely exceeding 160 oC depending on product.

Non-uniform moisture: See above. Non-uniform nip pressure: See above. Crushed roll. Sometimes called a "baggy sock roll" and is the result of stacking rolls on end in an excessively high pile which in turn causes the lower rolls to fail in an axial direction. Excessive axial pressure: Stack rolls to a more conservative height.
