Abstract
The utility model relates to a wire frame for steel wire coil heat treatment, which comprises a wire frame core constructed by a steel tube, and a plurality of reinforcing steel bars fixed on the outer side of the wire frame core and evenly distributed along the length direction. The utility model adopts a plurality of reinforcing steel bars as the support for annealed wires, adopts the hollow steel tube as the support for the reinforcing steel bars, and can improve the thermal fatigue resistance performance without using special steel material. Besides, as the wire frame adopts conical structure, the wire coil cannot be damaged due to the tight contact with the wire frame core during taking out process after thermal treatment, meanwhile the stability of the wire frame is also improved and the wire frame cannot fall off easily. A plurality of slots are formed between adjacent reinforcing steel bars and wire frame core, in the slots, namely vent holes are arranged on the wire frame core for the heat treatment atmosphere to evenly distribute in each corner, so as to reduce the local part decarburization phenomenon on the wire coil due to uneven atmosphere during the annealing process.
Description
Technical field
The utility model relates to a kind of steel coil of wire thermal treatment coil holder.
Background technology
At present, employed coil holder in the large-scale annealing furnace generally adopts four cylindrical steel sealing of tube to form quadrangulars, or adopts a large diameter steel pipe to form the center columnar structure, and it is one similar to the coil holder base that weld on the top again, but the less circular top cover of diameter.Because temperature is higher in the annealing furnace, thermal treatment is reused for a long time with coil holder, must possess certain thermal fatigue resistance.Tradition rolling wire annealing stove coil holder, equipment producer all recommends to use the 0Cr18Ni10Ti stainless steel to make coil holder, and 240 millimeters steel pipes of diameter are adopted at the center, the non-domestic steel market conventional products of material, the cost of manufacture height, fabrication cycle is long; In addition, at above-mentioned second kind center columnar structure, because whole coil holder is higher, the processing back coil of wire is difficult for drawing off.After particularly smart line was annealed, coil of wire strength ratio was lower, was easy to cause the collision of the coil of wire and coil holder during taking-up, thereby the damage coil of wire reduces quality product even causes product rejection or reprocess the change size.
The utility model content
The utility model has overcome above-mentioned shortcoming, provides that a kind of cost is low, service-strong thermal treatment coil holder.
The technical scheme in the invention for solving the technical problem is: a kind of thermal treatment coil holder, and comprise the coil holder core that constitutes by a steel pipe and be fixed on the described coil holder core outside, and equally distributed along its length a plurality of reinforcing bars.
Distance gradual change from top to bottom between described coil holder core and the reinforcing bar increases, and makes coil holder integral body be cone-shaped.
Can be provided with stiffening web between described coil holder core and the reinforcing bar.
The bottom of described coil holder core can be provided with base, and described reinforcing bar is also fixing with described base welding.
The top of described coil holder core can be provided with hoisting ring, is natural light degree of slipping over coil holder core junction around the described hoisting ring.
Described hoisting ring can extend upward also by described reinforcing bar, and bending constitutes.
Can be provided with a plurality of pores on the described coil holder core.
Described base can comprise doughnut-shaped steel plate and be arranged on the supporting steel plate that radially distributes between doughnut-shaped steel plate that the bottom of described reinforcing bar and the welding of described supporting steel plate are fixing.
The utility model adopts the support of a plurality of reinforcing bars as the annealing wire rod, and hollow steel pipe need not to use special steel as the support of described reinforcing bar, just can improve thermal fatigue resistance.In addition, whole coil holder adopts conical structure, after thermal treatment finishes, prevents that the coil of wire that takes out from producing damage with the collision of coil holder core, and the while has also strengthened the stability of coil holder, difficultly topples over.Between adjacent reinforcing bar and coil holder core, constituted some grooves, and in groove, promptly the coil holder core is provided with pore, helps heat-treating atmosphere and be full of each corner, reduce in the annealed process, because of the uneven reason of atmosphere causes coil of wire partial decarburization phenomenon.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in fig. 1, the utility model comprises the coil holder core 2 that is made of a steel pipe and along the equally distributed a plurality of reinforcing bars 4 of described coil holder core 2 length directions, described coil holder core is provided with a plurality of pores 7.Be provided with the stiffening web of making by steel plate 5 between described coil holder core 2 and the reinforcing bar 4.The gradual change from top to bottom of the width of described stiffening web 5 increases, make between described coil holder core 2 and the reinforcing bar 4 distance also gradual change from top to bottom increase, therefore make whole coil holder form up-small and down-big cone structure.The bottom of described coil holder core 2 is provided with base, and described base comprises doughnut-shaped steel plate 3 and be arranged on the supporting steel plate 1 that radially distributes between doughnut-shaped steel plate that the bottom of described reinforcing bar 4 is fixing with each described supporting steel plate 1 corresponding also welding.The top of described coil holder core be provided with by described reinforcing bar extend upward and bending constitute hoisting ring 6.
Based on said structure, the utility model adopts the support of a plurality of reinforcing bars 4 as the annealing wire rod, and Hollow Steel 2 pipes need not to use special steel as the support of described reinforcing bar 4, just can improve thermal fatigue resistance, and fabrication cycle is short, and comprehensive cost is low.And whole coil holder adopts conical structure, after thermal treatment finishes, prevents that the coil of wire that takes out from producing damage with the coil holder collision, and the while has also strengthened the stability of coil holder, difficultly topples over.Between adjacent reinforcing bar 4 and coil holder core, some grooves have been constituted, and in groove, promptly coil holder core 3 is provided with pore, helps heat-treating atmosphere and is full of each corner, minimizing is in the annealed process, because of the uneven reason of atmosphere causes coil of wire partial decarburization phenomenon.
More than thermal treatment provided by the utility model is described in detail with coil holder, used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
