Quenched and Tempered Reinforcement bars The reinforcement steel bars (rebar) are produced these days by the application of the technology of quenching and tempering of the bars during its production in the rolling mill. The rebars produced by this technology are popularly known TMT (thermomechanically treated) reinforcement bars.
The water quenching and self tempering treatment is applied directly in line after the finishing stand without any reduction of rolling speed or loss of productivity. By a judicious combination of Tempcore treatment and microalloying chemistry new higher grades (yield strength higher than 700 MPa and tensile strength higher than 800 MPa) can
steels. (In the process the quenching gas is backfilled Into the vacuum fur nace and recirculated through a con vectiondominated watercooled heat exchanger.) Present vacuum furnace tech nology provides gas quench capa bility at pressures of 2 to 20 bar (15 to 285 psig). In the United States pressures in the 2 to 10 bar (15 to 135
Rolling abnormalities can also cause roll breakage. Other reasons for roll failures include unreasonable design of rolls and the roll grooves excessive single pass deformation deep fire cracks fatigue and spalling etc. Some of the important reasons for roll abnormalities and failures are described below.
High vacuum operation. Onebar/twobar quench cooling. Features Standard oneyear warranty. This is a totally packaged and assembled unit that is shipped as one piece requiring only the water gas and power to be connected to the appropriate locations. This furnace meets AMS 2750E Class 5 uniformity specifications.
The production line can quench and temper (quench and temper) steel bars with a diameter of 120140mm. The heating mode is online continuous heating. The complete set of round steel quench and temper heat treatment furnace production line only needs a crane to lift the steel bars onto the storage rack and other ac

Quenching and tempering achieves an extremely finegrained and homogeneous microstructure. They are also called QT bars. QT steel bars are characterized by high strength and good ductility. We can provide you Quenched and Tempered Bars of grades such as SAE4140 etc. For details contact Mr Mithun Gupta on 91 .
It is essential that a manufacturer understand how a specific alloy will react in order to select the best material for an application. Of course quenching is known to make the metal in question brittle and so it is often necessary to apply other processes before or after quenching to ensure success or to avoid quenching all together. Today
A quenching apparatus for quenching elongated bartype workpieces wherein a plurality of interchangeable roll stands comprised of generally horizontal and vertical roll pairs define an elongated workpiece pass. At least one of the rolls of each roll pair is moveable towards and away from its associated roll normal to the workpiece pass in order to accommodate workpieces of various dimensions.
In bar mills directly after the last rolling stand the bar passes through the Cooling System achieving a short and intensive cooling of the surface. Because of the reduction in the temperature at a rate higher than the critical rate for martensite quenching the surface layer of the rebar is converted to a hardened structure while the core

The prohibitive cost of a two atmosphere helium backfill was 1 065. Our new furnace will enable us to fully harden three 2000pound roll dies at once using the more costeffective process gas of nitrogen. In contrast the cost of a 10 atmosphere backfill of nitrogen will be only 89.". Hill predicts that with these increased efficiencies and
Introduction. Quenching is a heat treatment process that involves heating steel to a temperature above the critical temperature Ac3 (hypoeutectoid steel) or Ac1 (hypereutectoid steel) preserving the heat for a period of time to allow for complete or partial austenitization of the steel then cooling it off rapidly at a rate above the critical cooling rate to a temperature below Ms for
4140 Hot Rolled Bar. OVERVIEW. SIZES FORMATS. CHEMICAL PROPERTIES. MECHANICAL PROPERTIES. OVERVIEW. Standard alloy steel. This grade has good wear resistance toughness ductility and hardness. It is especially strong when in the quench and tempered state.
The price of steel bar quenching and tempering heat treatment production line is affected by many factors and the specific factors are as follows 1. The quality of steel bar quenching and tempering production line directly affects its price.
QBar Quenchingsystem is an ideal solution for producing high strength rebar. The quenching and tempering configuration can be implemented in new or existing mills to economically produce quenched rebar.
