What Aspects Regarding the Manufacturing and Application of Tun

  • Because of their superior performance, tungsten carbide plates rollers have become increasingly more widely used in the production of steel in recent years. However, despite recent improvements, there are still some problems associated with the manufacturing and utilization of carbide rolls.

    1. Conceive a novel composition for the roller shaft material. Conventional roller shafts made of ductile iron will have a difficult time withstanding increased rolling power and delivering a greater torque. Consequently, the development of high-performance cemented carbide composite roll shaft materials is required.

    2. In the process of producing carbide rollers, the residual thermal stress that is caused by thermal expansion between the inner metal and the outer cemented carbide must be reduced as much as possible, if not eliminated entirely. One of the most important aspects that goes into determining how long a roller will last is its carbide residual thermal stress. Because of this, the difference in the coefficient of thermal expansion between the chosen inner metal and the cemented carbide that surrounds it should be as small as is practically possible, and one should also take into consideration the possibility of removing any residual thermal stress from the carbide roller ring through heat treatment.

    3. Because of the differences in the rolling force, rolling torque, and heat transfer performance of the various racks, the various racks should adopt different grades of tungsten carbide rollers in order to ensure a reasonable match of the strength, hardness, and impact toughness.

    In the rolling of wire and rod, conventional cast iron rolls and alloy steel rolls have been replaced by tungsten carbide rollers, which have shown a great deal of superiority. Furthermore, the ongoing development of roller manufacturing techniques and use technology will continue to expand the applications of carbide roller rings, and these rings will become more important in rolling machining with wider applications.

    How to make tungsten carbide rollers?

    How does Ukocarbide. com make tungsten carbide roller?

    Ukocarbide. com is a reputable business that has been in operation for more than 16 years and has become an industry leader in the production of tungsten carbide cold rollers of all types (PR, FO, CA/RT/RO).

    How is a tungsten carbide roller produced by the company Ukocarbide. com?

    There are four primary production processes, which are as follows:

    Pick the highest-quality raw material. Ensure 100% virgin. Before production begins, there will be a stringent inspection of the material (analysis of C percent and other chemical elements).

    Inspection carried out while production is underway. Maintain a record of each stage of production, including inspections of the mixed material (WC powder combined with Co powder), inspections of the sintered product (Hardness, density, TRS...), and so on. Every index ought to be subject to stringent control.

    The grinding and ribbing are done with the customer's required size and logo markings.(if you want to view the content, click here)

    Before packing, there will be an inspection. Ensure that each and every piece of tungsten carbide rolling stock is in pristine condition and of the highest quality.

    In addition to this, Ukocarbide. com offers a service for repairing (regrinding) tungsten carbide rollers.

    An outline of the progression of the roller throughout history

    The development of metallurgical technology and the evolution of rolling equipment have both contributed to the ongoing evolution of both the types of rolls available and the processes by which they are produced. The rolling of soft non-ferrous metals in the Middle Ages was done with rolls made of low-strength gray cast iron, which was cast from iron ore. The United Kingdom achieved mastery of the technology necessary for the production of chilled cast iron rolls for rolling steel plates around the middle of the 18th century. The second half of the 19th century saw significant technological advancements in European steelmaking, which necessitated the rolling of larger tonnage steel ingots. This was necessary because the strength of gray cast iron or chilled cast iron rolls was not sufficient to meet the requirements. Rolls of ordinary cast steel contain between 0.4 and 0.6 percent carbon steel. The introduction of heavy-duty forging equipment has further contributed to the enhancement of the already formidable durability of these forged rolls' composition. Cast and forged hot and cold rolls have seen significant improvements in their wear resistance and toughness as a result of the introduction of alloying elements and the heat treatment processes, both of which were pioneered in the early 20th century. The surface quality of the rolled strips can be improved by the addition of molybdenum to the cast iron rolls that are used for hot-rolling the strips.

    The core strength of the casting roll is significantly improved as a result of the rinsing compound casting. After World War II, there was a significant increase in the use of alloying elements in rolls. After rolling equipment has grown in size, continuousness, high speed, automated development, increased rolling material strength, and increased deformation resistance, this is a higher requirement for roll performance. as a consequence ofRolls made of semi-steel and rolls made of ductile iron appeared during this time period. In the decades following the 1960s, powder tungsten carbide rolls were eventually developed with great success. The introduction of centrifugal casting technology and differential temperature heat treatment technology for rolling rolls in the early 1970s in Japan and Europe led to a significant improvement in the overall performance of strip rolls. Both of these technologies are still in use today. Rolls made of composite materials and cast iron with a high chromium content have also been used successfully on hot strip mills. Rolls made of forged white iron and semi-steel were utilized in Japan during the same time period. For the finishing of small-sized steels and wire rods, Europe began using cold-rolled rolls in the 1980s. These rolls were made of high-chromium steel rolls and ultra-deeply hardened layers. Additionally, special alloy cast iron rolls were used. The advancement of modern steel rolling technology has resulted in the creation of rolls with greater performance capabilities. The strong and toughness forged steel or ductile ink cores that are produced by the centrifugal casting method and other new composite methods such as the continuous casting compound method (CPC method), spray deposition method (Osprey method), electroslag welding method, and hot isostatic pressing method, respectively, are cast using these methods. On new generation profiles, wire rods, and strip mills in Europe and Japan, respectively, cast iron, composite high-speed steel rollers, and metal ceramic rollers have been applied.
