Tmt stands for the thermo mechanical treatment of bars.
Tmt bar rolling mill process.
If a mill rolls 80 of the calendar year that is 365 x 24 x 0 80 7008 hours.
The thermo mechanical treatment involves 3 essential steps that are.
If the mill rolls 800 000 tons per year it runs at an average production.
Tmt rod or tmt bar manufacturing is a medium or large scale operation.
Our rolling mill has facility to roll tmt steel bar with the most modern crm centre de recherches metallurgiques belgium tempcore technology themo mechanical treatment which is the quenching process used by producers in the nation namely tata steel and visakhapatnam steel plant.
The very first step of the manufacturing process involves passing the steel wires through a rolling mill stand.
In this article we intend to explore how to start a rolling mill business or tmt bar manufacturing business.
Best quality tmt bars pass through series of processes that determines the strength flexibility of it.
We are manufacturing hot rolling mill products from last four decades.
Tmt bar mill offered are backed by precision design and construction standards that make these efficiently handle the demands of tmt bar production.
Wire rod rolling mill up to 600 000 tons per year with high speed rolling technology re bar rolling mill up to 1 000 000 tons per year with slit rolling technology light section rolling mill structure rolling mill heavy section rolling mill up to 700 000 tons per year steel.
After the bars pass the outer surface of the bars solidifies while the core remains hot.
Good figures for rod and bar mills are 90 to 93 for structural mills the good mill utilization figures are 75 to 78.
In this the steel bars are passed through a specially designed water cooling system.
It is a highly profitable business depending on the manufacturing technology you are using.
This creates a temperature gradient in the bars.
Understanding rolling process in long product rolling mill.
The full form of tmt is thermo mechanical treatment.
The mill is backed by complete process support as required to achieve.
The manufacturing process of tmt bar involves series of processes like rolling water quenching heat treatment cooling at various stages of manufacturing.
Thereafter these rolled steel wires are again passed through the tempcore water cooling system.
