lt is inevitable to find the microcrack on the rolling groove. The microcrack will gradually extend, stretch and deepen. The groove shall be repaired immediately while the depth of crack reaching 0.2-0.4mm. Otherwise, the crack will deepen quickly, which leads to a risk of broken roller. The range of normal yield is reguated as follows:

With over twenty years’ experience on the production of cemented carbide roll rings, LMM has established an inte-grated system including R&D and extraction of powder and production and marketing of alloy. Through our professional service, you can make the correct choice for the material to match your product.

During the use of Cementer carbide roll , under good cooling conditions, a thin and dense oxide film is formed on the surface of the roll body. This uniform, thin and dense oxide film can exist for a long time without falling off, so that the wear resistance of the Cementer carbide roll is significantly improved.

The tungsten carbide rolls is mainly used on the finishing mill for bar, deformed steel bar and common wire. In this way, we can greatly reduce the frequency of changing groove and roll, thus to reduce the labor intensity and improve the work efficiency. The surface quality and yield shall be improved to a maximrurn degree, which leads to a rernarkable ecornmoic benlefit.

Single-End Cobalt drills now available with Thru-Tool Cooling (TTC). The TTC design offers superior cooling and chip removal characteristics to promote a longer tool life. They are available in ST Type 60°, R Type and B Type 60°/120° forms. Tool coatings available—please call for a quote.

To convert from cast iron or steel rolls to carbide rolls, LMM carbide roll product experts will work with the rolling mill to improve roll cooling, machining and handling capabilities. Most rolling mills can be easily changed from cast iron to tungsten carbide.

The sleeve insertion and assmbly of cemented carbide roll rings shall be carried out in accordance with the requirementsof precision. There shall be appropriate space between the roll rings and axle or between the roll rings and sleeve. The fit is neither tight nor loose. You should check whether the roll rings contorms to the technological requirement and cleanthe mounting surface of roll rings, sleeve and axle before the installation. it is prohibited to beat the roll rings with hammeror other hard things while assemblying.

The S Type Centerdrill is a dual-purpose drill used for the heaviest duty burnishing and chamfering applications where a more rigid setup is required. This drill has a 60° angle design, followed by an 82° angle flare making it a dual-purpose tool. Snap Ring grooves are offered in HSS, standard drill sizes #14 thru #18; please refer to our Technical Information page to learn more about their function.

It can be seen from the metallographic photos that the metallographic structure of the Cementer carbide roll is much better than other materials in terms of the shape, quantity, size and distribution of carbides, as well as the matrix structure and grain size.

The Metric ST Type Centerdrill provides the same advantages as the standard ST Type Centerdrill but are available in standard metric sizes.

Titanium is the ideal choice for difficult applications in various industries such as medical, energy, chemical processing, and aerospace.

lt is normal to find the microcrack on the rolling groove. The groove shall be repaired immediately while the depth of crack reaching 0.2 mm. lt is necessary to prevent the roller from being broken. While repairing, we must ensure to remove the crack thoroughly. Otherwise, it will bring a potential risk to next rolling.It is difficult and inconvenient to check if the surface is polishing. To ensure the complete remove of microcrack, we can increase the grinding quantity. Under thenormal condition, the repair is controlled in the range of:

How to find a trustworthy Tungsten Carbide Rolls manufacturerIf you want to find a trustworthy Tungsten Carbide Rolls supplier with long-term cooperation, maybe you need to concern about as the following

Proper cooling is essential to ensure optimal performance of carbide rolls. The recommended minimum pressure is 4 to 6 bar and 250 to 300 liters per minute per molding.

The WC powder, cobalt powder, and other rare elements are formulated in good proportion. Join the ball mill through the 24 hours of wet grinding, and mixed into the forming powder, then put them into the spray drying tower.

Compression molding will be prepared and put the powder into the mold, press molding with a hydraulic press; Put the roughcast into the furnace and burn it into the roll roughcast.

LINK Hey Drills offer the high quality and precision workmanship of our standard line of Centerdrills, with strategically positioned flats for locking set screws and to accommodate adjacent tooling. The position of the center flat is exactly 90° from the Hey Flat location.

The main raw material is tungsten carbide powder. LMM funded 20,000,000.00 USD, and imported the carbide powder manufacture equipment in 2010.Tungsten carbide powder is produced by APT, and burning in electric heating rotary calcination furnace, and then come into being blue tungsten oxide, then through burning and producing the tungsten powder.

Centerdrills are used for centering parts to be turned between centers. Link Industries offers a variety of different types of centerdrills, material options and coatings to handle all of your applications.

As can be seen from the flow chart, roll manufacturing forms a closed-loop system from product design, production and manufacturing, use and maintenance, and improved design, and the quality of rolls is constantly improving.

Link Industries reserves the right to make changes, alterations, and substitutions to the products, services, or other information presented without prior notice. For the latest information contact Link Industries.

Due to their higher wear resistance, LMM tungsten carbide rolls last up to 20 times longer than cast iron rolls. This reduces mill downtime while increasing productivity and lowering operating costs

Before determining the grade of cemented carbide for every stand, we shall have a thorough understand about theirproperties so as to make the correct choice (Please refer to the Product manual).

The tungsten powder with good carbon black is added to the intermediate frequency carbonization furnace. In the end, the WC the powder was milled by the ball milling machine, and the high quality tungsten carbide powder was produced.

The tungsten powder is screened by a vibrating screen. And then through the air classification equipment, it is classified into different granularity.
