Tungsten carbide roll ring is an important part of the steel roll with a mass diameter ≤480mm and thickness ≤130mm. The tungsten carbide rolls for rolling mills is primarily applied in high-speed wire rod mill production lines, seamless pipe stretch reducing mill, three-dimensional rolls for cold-rolled ribbed steel bar, and composite roll for hot-rolled bar screw thread steel, etc. Carbide rolls are made of the hardest metal on earth, they are harder than titanium rings and longer than gold rings. This ring is usually used as a seal, disc cone, and so on. The Facts about The Tungsten Carbide Roll: 1. The carbide roll ring is the most wearable ring on earth. 2. tungsten is about 10 times harder than gold, 5 times harder than tool steel, 4 times harder than titanium. 3. Due to its extremely high hardness, tungsten carbide roll rings can keep their shape and luminescence time for any other ring on the market for a long time. 4.

Pearlitic Nodular Cast Iron Roll Pearlitic nodular cast iron roll is a kind of spheroidal graphite iron roll, which is known as ductile iron roll and is a roll made by spheroidizing the molten iron with magnesium and pouring it into the sand-lined cold type. Due to the spheroidizing treatment, the graphite carbon inside the cast iron is changed from flake to spheroid, which eliminates the phenomenon of graphite tip stress concentration caused by flake graphite, which significantly improves the strength of cast iron, similar to the cast steel roll, but the abrasion resistance is much higher than the cast steel roll. There are three types of nodules of magnesium, cerium, and calcium and magnesium are commonly used. Spheroidal graphite iron roll can be applied in open-rolling mills, roughing mills and rolling mills before finishing rolling on various sections and plates. When the finished roll bears a large load, it is best to use a ductile iron roll with a casting groove,
