Long Bar Induction Heat Treatment Production Line

With the rapid upgrading of heavy-duty mechanical supporting workpieces, the traditional long bar induction heat treatment production line furnace body has exposed many structural bottlenecks in long-term uninterrupted continuous operation. The original integrated single-layer welded frame has weak anti-vibration performance, and high-frequency induction thermal shock is prone to cause local deformation, frame shaking and coil offset deviation. In addition, the old-fashioned fixed integrated furnace cavity has poor heat insulation and airtight isolation performance, uneven induction heating temperature field inside the furnace, easy heat radiation loss, and poor matching linkage with feeding, induction heating and circulating cooling auxiliary mechanisms, which seriously affects the overall quenching and tempering forming quality of long bars, increases equipment failure shutdown frequency, and raises factory comprehensive operation and maintenance costs. Forever Electromechanical focuses on the actual working conditions of on-site induction production, and launches a full-process targeted structural upgrade for the supporting furnace body of long bar induction heat treatment production lines to empower stable and efficient intelligent production.

Forever Electromechanical’s core upgrade scheme optimizes and replaces the overall load-bearing framework of the furnace body in a targeted manner. It adopts high-strength low-alloy thickened steel profiles and assembled reinforced anti-deformation overall welding structure, matching integrated cast steel load-bearing base and multi-point shock absorption limit support assembly. Compared with the traditional single-layer simple structure, it can effectively counteract high-frequency electromagnetic vibration and continuous high-temperature thermal stress impact, stabilize the overall horizontal stress of the furnace body, completely avoid common faults such as frame distortion, side wall sinking and internal induction coil displacement, and greatly extend the overall service cycle of the induction furnace body and supporting electrical components.

Steel bar induction hardening and tempering line

At the same time, the furnace body internal cavity insulation and closed isolation structure are fully optimized and upgraded. The furnace lining is equipped with new high-temperature resistant nano-composite multi-layer heat insulation cotton and integral pouring refractory protective layer, and the joint gap of the split furnace body is equipped with high-elastic high-temperature soft sealing pressure strips in all directions. It effectively isolates internal induction heat radiation, reduces heat conduction loss by a large margin, realizes uniform and constant temperature in the full-length heating area of the furnace body, perfectly adapts to synchronous matching of medium-frequency induction heating, rapid temperature measurement and online constant temperature control, and ensures consistent metallurgical mechanical properties of each batch of long bar workpieces after induction quenching and tempering.

Furthermore, Forever Electromechanical adds a standardized modular quick-disassembly structure to the furnace body, independently reserves integrated reserved ports for induction coil wiring, circulating water cooling, online infrared temperature measurement and linkage feeding, and optimizes the compact overall layout of the furnace body. The upgraded furnace body is convenient for daily quick inspection, coil maintenance, internal ash cleaning and on-site rapid assembly and debugging. After actual on-line production verification, the upgraded production line has lower comprehensive energy consumption, more stable heating operation, greatly reduced abnormal failure rate, fully meets the high-standard batch production demand of various alloy long bars, and creates reliable high-efficiency induction heat treatment supporting equipment for industrial manufacturing enterprises.
