Today’s hot rolling processes require optimum and reliable products and components throughout the mill train.

We offer you a wide variety of standard grades to satisfy almost every application request. Special non-standard grades are also available, as well as a sophisticated R&D-department, that is continuously working on developing new grades.

Our tungsten carbide roll rings are available in standard block sizes and up to a diameter of 600mm, they come either ground but without grooves or ready-to-use, with grooves.

 

• high-performance rolls for hot rolling mills
• wide variety of standard grades
• available for nearly every rolling application
• excellent surface finish of the rolled product
• machining service and training available

 

Cemented carbide roll rings (also known as tungsten carbide roll rings) possesses good thermal conduction property. Compared with other materials, it is much better in terms of heat resistance, wear-resistance and strength. What’s more, its hardness reduces a little under the condition of high temperature. So, the cemented carbide roll rings is invented with the appearance of a high-speed wire rod mill. With the development and improvement, it is widely applied in the production of high-speed wire, bar, and deformed steel bar.

Production Process and Production Facilities

The main raw material is tungsten carbide powder. HXY 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.

Screened & Classified:

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

Ball Milling & Mixxing:

Tungsten powder in a certain proportion, adding carbon black and other additives after ball milling and mixing.

High Quality TC Powder:

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.

Forming Powder:

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.

Press & Burning:

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.

Finish Machine:

Through flat grinding, internal hole grinding, and cylindrical grinding comes into being the product of the ring. Also according to different rolling, different rolling mills, processed into wire grooved roll rings, wire thread roll rings, bar combination rolls, and roll steel.
