The present invention compared with prior art has the following advantages:
1, the wire rod heating and cooling are full and uniform, and it is lengthened to 9800～10000mm with preheating section length by original 7960mm, and cooling section length is lengthened to 2225～2435mm by original 2200mm.
2, avoided spark phenomenon, the diameter of annealing wheel is increased to the 460mm into φ 440～φ, increased the contact length of wire rod on annealing wheel, make wire rod contact with annealing wheel well, and then effectively avoided owing to the wire rod spark phenomenon that loose contact causes on annealing wheel, improved the work-ing life of annealing nickel strap simultaneously.
3, owing to change into the cooling tank in the cooling section horizontally disposed, guarantee that wire rod can both fully cool off in any position, and, can guarantee that the fluid temperature that enters cooling tank is not higher than specified temperature timely and effectively to the cooling fluid cooling owing in coolant circulation system, be provided with plate-type heat exchanger.
4, carbon brush wheel good heat dissipation effect, it is provided with air cooling system by taking turns at carbon brush, thereby has effectively guaranteed the insulation level of insulating element.
5, applicable to the annealing of major diameter wire rod, being particularly useful for diameter is the wire annealing of φ 3.5mm～φ 4.0mm, its quantity that goes up carbon brush by the machine carbon brush wheel of will annealing is increased to eight groups, has increased the annealing electric current greatly, for big wire annealing provides prerequisite.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
