ROLLER HEARTH FURNACE FOR HARDENING &TEMPERING OF LARGE BARS/PIPES
<p>VRL-L series heat-treatment line pioneered by ARES is suitable for continuous quenching and tempering, normalizing, annealing, solid solution, and other heat treatments of large-diameter thick-walled tubes and bars of alloy steels, alloy structural steels, nickel-chromium steels, etc. With diameters ranging from 80-400mm. VRL production lines can have different equipment combinations for different heat treatment process requirements.</p> <p><br /> The heating furnace of VRL-L heat treatment lines adopts V-shaped inclined rollers, which enables the furnace to have a heat straightening function: under high temperatures, the constraint of the furnace rollers on the raw material can improve its straightness during the heating process. Adopting the self preheating burner heating system, the furnace temperature is accurately controlled.</p> <p><br /> The quenching machine adopts an annular air or water ring to achieve an all-round strong and uniform cooling of the treated materials, ensuring the quenching depth and straightness of the material and reducing the straightening process. According to demand, the tempering heat treatment furnace can be equipped with either V-shaped inclined rollers or flat rollers, and there is a cooling device behind the tempering furnace to avoid material brittleness during tempering.</p> <p><br /> In addition, The VRL-L series heat treatment line can be configured with Heat Treatment Line Remote Service System (RDMS) and Industrial Furnace Production Data Intelligent Analysis System (FDAS).</p> <p> </p> <p><strong>Material：</strong> Alloy structure steel, Stainless steel<br /> <strong>Product shape： </strong>Large diameter bars and pipes<br /> <strong>Product size： </strong>Φ80-400 mm<br /> <strong>Treatment process：</strong>Quenching and tempering,Normalizing<br /> <strong>Cooling style：</strong> Water cooling, air cooling, fog cooling<br /> <strong>Maximum temperature：</strong><strong> </strong>1050℃<br /> <strong>Fuel：</strong>NG, Mix gas, Electricity<br /> <strong>Capacity：</strong>5.0 ～ 20.0 t/h</p>
