Description
Technical Field
The utility model relates to a production device of a steel wire for a tire bead, in particular to a composite wire supporting brick of a steel wire heating furnace for a tire bead, which has excellent wear resistance.
Background
The steel wire for the tire bead is used as one of two main framework materials in a tire product, and the wire diameter requirement is usually met by adopting a high-carbon steel wire element through dry drawing. In the process, the plastic deformation of the steel matrix is mainly utilized. In the plastic deformation of steel, mainly under the action of external force, the sorbite and the like in a metallographic structure undergo elongation deformation, and in the process, micro cracks with different degrees can be generated. This crack will further propagate as drawing continues, eventually leading to a break of the steel wire during drawing. In order to avoid the fracture of the steel wire, when the steel wire is drawn to a certain wire diameter, the steel wire needs to be subjected to heat treatment, the steel wire is heated to austenitizing phase transition temperature, cracks generated in the early stage in the process of austenite transformation of a steel matrix are eliminated, and the steel wire is transformed into a sorbite structure capable of being drawn continuously. The austenitizing structure phase transition temperature of the steel wire is over 930 ℃, and the steel wire needs to be overhead routed in order to heat the steel wire in the heating furnace fully and uniformly. At present, the heating furnace is mostly made of refractory materials and sintered into wire supporting bricks with T-shaped cross sections, and the wire supporting bricks are placed in a hearth at intervals to play a role of overhead steel wires. Although the wire supporting brick has a good high-temperature resistant effect, the wire supporting brick has the defect of poor wear resistance, the service life is basically one month, the wire supporting brick is worn to be invalid by a steel wire, and the wire supporting brick needs to be stopped for replacement.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is to overcome the defects of the background technology and provide the composite wire supporting brick of the steel wire heating furnace for the tire bead, which has excellent wear resistance, and the composite wire supporting brick can meet the wear resistance requirement of a high-temperature environment, so that the production efficiency of a production line is improved.
The technical scheme provided by the utility model is as follows:
the composite wire supporting brick of the steel wire heating furnace for the tire bead with superior wear resistance comprises a wire supporting brick made of a refractory material, and is characterized in that: the upper surface of the wire supporting brick is covered with a layer of wear-resistant protective cover; the wear-resistant protective cover is matched with the upper surface of the wire supporting brick in shape so as to support steel wires in the heating furnace.
The wear-resistant protective cover is a stainless steel sheet; the stainless steel sheet is bent into a shape suitable for the wire supporting brick.
The utility model has the beneficial effects that: after the composite wire supporting brick is adopted, when a steel wire on a production line enters a treatment line in a heating furnace for operation, the steel wire is not in direct contact with the wire supporting brick any more, but is lifted by a stainless steel sheet, so that the service life of the composite wire supporting brick is prolonged (the wear-resistant protective cover can be replaced once a year, and the replacement of a refractory material wire supporting brick is not needed generally).

Detailed Description
The following further description is made with reference to the embodiments shown in the drawings.
The composite wire supporting brick of the steel wire heating furnace for the tire bead with excellent wear resistance shown in figure 2 comprises a wire supporting brick 1 made of refractory materials, and the cross section of the wire supporting brick is T-shaped. During operation, the steel wires 3 arranged in rows are lifted by the wire supporting bricks arranged at intervals, so that overhead arrangement is realized. This is the wire support arrangement in conventional furnaces.
The improvement of the utility model is that the upper surface of the silk supporting brick is covered with a layer of wear-resistant protective cover 2; the wear-resistant protective cover is matched with the upper surface of the wire supporting brick in shape, and the steel wire in heating can be lifted in the heating furnace only by covering the wire supporting brick.
Preferably, the wear-resistant protective cover is a stainless steel sheet (further, a 310S-type heat-resistant stainless steel sheet is selected); the stainless steel sheet is bent into a shape suitable for the wire supporting brick.
