Understanding Rolling Process in Long Product Rolling …

Good figures for rod and bar mills are 90 % to 93 %, for structural mills, the good mill utilization figures are 75 % to 78 %. If a mill rolls 80 % of the calendar year, that is 365 x 24 x 0.80 = 7008 hours. If the mill rolls 800,000 tons per year, it runs at an average production rate of 114.16 tons/hour.

is known as continuous casting, because the process never stops. If the steel mill has rolling equipment, the hot metal may be rolled rather than cast. Slabs, ingots, billets and blooms are often shipped by sea in transit to a rolling mill where they can be rolled into long products such as profiles, beams and channels.

TMT Bar Manufacturing Plants and Process with Latest ...

The hot rolled bar from the finished mill stand enters into the 'Thermex System' and is rapidly cooled by a special water spray system. This rapid cooling hardens the surface of the TMT Re-bars to a depth optimized for each section, forming a martensitic rim while the core remains hot and & Austenitic. This rapid cooling is called quenching.

IS : 1786 - 2008

VIZAG TMT bars have rare combination of high strength with excellent ductility. The tensile to yield strength ratios are always greater than 1.12. In normal bars, the increase in the yield strength of the bars is accompanied by the loss of percent elongation. But in the case of VIZAG TMT bars this loss is negligible and the

Calculating Machining Time For Any Machining Operation

It is often necessary for CNC people to determine how long machining operations will take to perform. You may be trying to determine which of two or more processes will be used to machine a workpiece - or you may just be wondering how long a machining operation will require to complete. Frankly speaking, the formulae related to calculating machining time are pretty …
