Rolling Mill Parts

TMT Quenching System

Quenching and self tempering system also known as Thermo mechanical treatment Consist of a  steel fabricated quenching box where Hot bar during rolling is subjected to rapid Cooling by a series of cooling elements Located within. Water from a circulation system is pumped to these cooling nozzles through control valves. Within the box, bar surface is rapidly cooled with core of the bar remaining hot. Once the bar exit out of quenching box, heat from the core will reach the outer surface to give a tempering effect.

INSTRUMENTATION

All process parameters are precisely controlled to achieve the right mechanical properties of the finished QST bar through a dedicated instrumentation system. 

System consists of two radiation pyrometers to monitor the bar temperature before & after the quenching process, Transmitters to monitor the water flow, pressure, temperature. All process parameters are displayed on operator computer monitor. Water flow to the system is controlled by a motorized control valve on the main header.

BY PASS LINE

A by pass line is provided on the quenching box frame to convey the non quenched bar to cooling bed when the QST process is not in operation.

Lubrication Units

AVTAR Oil lubrication systems are used to maintain regular supply of ambience temperature oil to mating parts of Gear Boxes in Rolling Mill.

Oil Lubrication Unit is PIT Hole type box, fabricated out of M.S. Plate body come complete with all accessories like Oil Reservoir , Heat Exchanger, Oil Strainer, Contact Thermometer / Manometer, Duplex Fitter, Pressure Gauge, Pressure / Flow Switch, Inlet & Outlet Nozzles, Lubricating Pump Unit, Complete Pipeline to & from the Gear Boxes. Complete with Control Panel.

The system is so designed that the lubricant flows back to the reservoir under the influence of gravity. AVTAR manufacture all standard and custom size oil lubrication systems bases of the LPM etc.
