Tungsten carbide rolls have the characters of high wear resistance, high corrosion resistance and good compressive properties which is an important part of the steel bar and wire rod rolling.
Tungsten carbide roll bushing is primarily applied in high-speed wire 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.
The mass diameter ≤480mm, thickness ≤130mm. We have an annual production capacity of 200 tons, which fully meets the steel bar and wire rod manufacturers demand for the tungsten carbide roll rings.
Carbide rings 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, instrument and so on.
The Facts about The Carbide Ring:
1.Carbide 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 rings can keep their shape and luminescence time for any other ring on the market for a long time.
4.Carbide ring, known as the "permanent polishing ring"
5.Carbide rings do not bend.
Standard includes ISO, GB, ASTM, DIN, JIS. OEM and ODM are available
Application
bar & wire rod mill, hot strip mill, cold strip mill, PC mill, section mill, plate rolling mill, non-ferrous mill, etc.

Forging Steel Roll
Forge steel rolls have better toughness, surface hardness uniformity and fatigue resistance, are used to rough rolling rolls and backup roll for cold rolling mill and hot rolling mill.
Forged steel rolls are made from steel ingots by forging. Forging can solve metallurgical defects such as loose and shrinkage holes in the ingot, and crush the coarse cast structure to obtain a high-quality roll with dense structure and uniform composition. Forged steel rolls have better toughness, surface hardness uniformity and fatigue resistance than similar casting rolls. In order to meet the specific requirements of different rolling mills and rolling conditions, different alloy elements can be added into the steel for improving the performance of rolls.
The production process of forged steel rolls includes smelting, ingot casting, forging, post-forging heat treatment, rough processing, final heat treatment and finishing. Forged steel rolls are heat-treated differently depending on the material and application.
Standard includes ISO, GB, ASTM, DIN, JIS.
OEM and ODM are available
Application
cold rolling mill work roll and strip rolling mill working roll and backup roll
H-type steel universal –shaft
High-speed roll(HSS roll)
Cr4 steel backup roll
Cr5 forged steel roll
Graphitic Steel Roll
The graphitic steel roll has similar features and usage to semi-steel adamite roll. Standard includes ISO, GB, ASTM, DIN, JIS.
Application
Work roll of two-high strip mills machine, medium plate reversible rolling mill,
a rough rolling mill, blooming mill, steel billet rolling mill, high-speed wire rod roughing mill bar, frame.
Metallographic Structure
The metallurgical structure of roll-body work layer is: Pearlite + carbide or fine pearlite + a little bainite + carbide
(1) Abrasion resistance is the most common form of damage of the mill rollers, which affects the surface precision and dimensional accuracy of the rolled piece. Since the wear mechanism of the rolled piece and the roll in the roll gap is complicated, there is still no wear resistance. The index can characterize the roll wear resistance, so the wear resistance of the roll can only be judged indirectly based on composition and hardness.
The basis for selecting the hardness of the rolls is the rolling stock, the rolling mill and the rolling conditions, as well as the cost, and sometimes importantly, the operating habits and experience with the rolls. The higher the hardness, the worse the toughness must be considered. The hardness of the rolls is generally measured in terms of Shore hardness because the Shore hardness machine is portable and can be used on rolls without leaving a small indentation on the rolls.
(2) Toughness index The toughness index will be selected according to the main damage of the roll surface. The toughness indexes that can be selected are yield strength, impact toughness, hot and cold fatigue, fracture toughness, and contact fatigue strength. According to the specific use conditions of the rolls and the main damage mechanism, it is generally only necessary to select one of them as the roll toughness index.
Rolls may have residual stresses due to uncoordinated deformation during casting, heat treatment, surfacing, and cutting. When used, the residual stress and the working stress are superimposed to jointly induce different damage phenomena.
(3) The strength requirements of the working layer and the core of the core strength roll are different. Generally speaking, the roll strength should be the core strength to resist bending and torsion stress and avoid breaking the roller.
The working layer of the roll sometimes requires strength directly, such as compressive strength, which can represent the ability of the roll surface to resist fracturing. Due to the high cost of testing the toughness index, the strength of the roll surface against various cracks is sometimes roughly indicated by the strength.
