Tungsten carbide roll ring has characteristics of good wear resistance, high temperature red hardness, thermal fatigue resistance and thermal conductivity and high strength, it is a key component of high-speed wire rod rolling. Tungsten carbide roll ring is mainly used for high-speed wire rod mill pre-finishing unit, and finishing units, reducing sizing unit, rolling play area and improve the performance of rolling material effect decreases. Tungsten carbide roll ring line production to meet the needs of making various types of high carbon steel, alloy steel and special steel.
Tungsten carbide roll ring material is developed on the basis of the tungsten carbide tool material, it is made of refractory metal compound (WC) as a matrix, and transition metals (Co, Fe, Ni) as the binder phase. Tungsten carbide roll ring has good abrasion resistance, high-temperature red hardness, thermal conductivity and high temperature strength and other characteristics, it has been widely used in making high-speed wire rod, bar, rebar, and other rolling seamless steel pipe production. During normal use, the surface due to the impact of high frequency alternating thermal shock and hot water fog and thermal fatigue cracking, commonly known as crack, different forms of wear or fracture failure is the main reason in this case appears thermal fatigue crack initiation and propagation. When the groove face cracked it must be grinded to prevent crack propagation caused by abnormal breakage roller ring.
Tungsten carbide roll rings performance requirements
When the roller ring used, the roll diameter roller ring is smallest , and line the fastest, roll ring subjected to thermal shock highest frequency. Therefore, it requires roll ring material having excellent abrasion resistance to ensure the dimensions of finished wire after a certain amount of rolling ; and requires a high fracture toughness to resist the thermal expansion of the higher frequency shocks caused thermal fatigue cracks; the same time, need to have a high thermal conductivity to suppress thermal fatigue crack initiation. During use, the maximum operating speed of tungsten carbide roll rings up to 18000 r / min, and rolling up to the maximum temperature of the contact 1200 ℃. It is in this harsh working conditions, the roller ring wear resistance, toughness, resistance to thermal fatigue performance high demands. To achieve these performance requirements, often using coarse-grained low cobalt grades roller ring, such as WC-6% Co.
