Embodiment: the utility model is described further below in conjunction with accompanying drawing;

A kind of continuous annealer; Comprise dryer 8, degreasing machine 9,10 compositions of Abrollhaspel, it is characterized in that: Abrollhaspel 10 links to each other with degreasing machine 9, and degreasing machine 9 the other ends link to each other with dryer 8; The S roller was 7 before dryer 8 the other ends were provided with; Before the S roller be 7 to be 6 to link to each other with dancer roll, dancer roll is that 6 the other ends are provided with process furnace 5, process furnace 5 the other ends link to each other with holding furnace 4, holding furnace 4 the other ends with spray hydrogen cooling tank 3 and link to each other; It is 2 that spray hydrogen cooling tank 3 the other ends are provided with back S roller, and back S roller is that 2 the other ends link to each other with reeling machine 1.During practical implementation, feeding cart charging → Abrollhaspel unreels → winder collection → cross cut shears broken end → spot welding machine joint → degreasing machine oil removing → cleaning machine flushing with clean water → water proof roller dewaters → air flow dryer oven dry → stokehold centering → stokehold s roller and Abrollhaspel set up uncoiling tension and and stove after set up between the s roller stove internal tension → copper strips preheating → process furnace heating → spray but hydrogen-cooled → stove after s roller automatic centring device centering and and the s roller between set up copper strips tension force → shears docking → deviation correcting device correction → reeling machine and be with a rolling → paper placing machine structure to put paper → following trolley discharging.The degreasing function guarantees that copper strip surface is clean and contains minor amount of oil; Dryer guarantees that copper strips advances not water content of surface, stokehold; S roller system is for providing intermediate tension in the stove; Dancer roll system carries out trace to middle tension force and regulates, and guarantees the stability of intermediate tension; Process furnace, holding furnace are electrically heated, and the inside is full of nitrogen hydrogen protection gas, makes band can fully go back the true qualities of native copper in heat preservation zone; Spray hydrogen cooling tank cools off copper strips through spraying cold hydrogen, prevents high temperature oxidation; Reeling machine, through the hydraulic pressure center support system, the assurance band can be rolled up together.The utility model control system component is by temperature control unit; Dc drive control system; Tension pick-up control and tension force Weighting system; Converter plant; The photoelectricity center support system; The photoelectric error correction system; The MCC A/C transmission control; Moment control device; The Hydraulic Station system; The PLC PC of being furnished with various special functional modules; And computer data management system is formed.

It is industrial computer+programmable logic controller+programmable logic controller scheme that the electrical autocontrol overall system adopts IPC+PLC+PLC.Adopt field bus technique whole electrical autocontrol systems connection.Through exploitation, form the automatic control system that function meets the demands fully to above equipment reasonable disposition and application software.The outstanding feature of system has adopted collecting and distributing control theory promptly to control to want Decentralization to concentrate exactly.Burst control, burst are kept watch on, Fragmentation, realize centralized management through network service.Copper strips speed, tension force, furnace temperature realize monitoring and management by computer system completely.Adopt all-digital dc speed-regulating system, require system performance good, safety is high, satisfies high dynamic quality and high adjusting speed accuracy.In annealing process, speed needs to carry out with the form of S type curve given, guarantees at the initial section and the ending segment that quicken all excessively with smooth curve, and it is all very steady to reach startup in the annealing process, operation, docking process.Speed control need have that raising speed comprises startup, speed stabilizing, minimum velocity, parking, stops fast, anxious function such as stop.
