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.

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.

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.

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).

Decarbonizing Annealing Line (DCL): Cold-rolled strip steel is heated to the annealing temperature in a radiant tube furnace (RTF), slowly cooled to 600 ℃ with a cooling rate controlled at 10 ℃/sec at first, and then rapidly cooled below 100 ℃. The atmosphere inside the furnace is hydrogen (up to 75%) and nitrogen, and the protective atmosphere can be humidified, or a proper amount of ammonia gas can be introduced to achieve decarburization or nitridation of the strip steel. After annealing, the surface of the steel strip will be coated with MgO, and finally, the coating will be dried and cooled to the ambient temperature.

Final Hot-stretching and Flattening Line (FCL): 

After being coated with insulation coating, the strip steel is heated to around 700 ℃ by an open flame, then it proceeds into the radiation tube (RTF) and is heated to the process temperature, holding for a period of time. After that, the workpiece is slowly cooled to 600 ℃ with a cooling rate controlled at 10 ℃/sec and then rapidly cooled below 300 ℃. In this section of the furnace, nitrogen and hydrogen are used as protective atmospheres in the RTF. Finally, the strip steel is cooled to 80 ℃ using air jet cooling (AJC) after having been discharged from the furnace.

Annealing Line for Non-oriented Silicon Steels (ACL):

Cold-rolled steel strips are heated to the annealing temperature through a radiant tube furnace (RTF) or an open flame non-oxidation heating furnace and are uniformly heated for a certain period of time. The atmosphere inside the furnace is hydrogen and nitrogen, or a humid atmosphere is added to control the degree of decarbonization. After that, strips are slowly cooled to 600 ℃ at the beginning and then quickly cooled to 80 ℃. After annealing, the surface of steel strips will be coated with insulation coatings which will be dried and sintered afterwards.
