Tungsten Carbide Roll Rings, also known as hard alloy roller ring, has been widely used in the rolling production of high-speed wire, bar, threaded steel, seamless steel pipes, etc. due to its good wear resistance, high-temperature hardness, heat fatigue resistance, thermal conductivity, and high strength.

Article 16 of the "Regulations on the Recall of Defective Automobile Products" stipulates: "Manufacturers shall report to the competent department the defects of their automobile products; they shall not handle the defects of their automotive products in an improper manner." What is the wrong way? AQSIQ’s relevant experts clearly stated on the 2nd at the “Policy for the Recall of Defective Automotive Products†publicity meeting that if a car manufacturer finds a defect in the product, it may not solve the product defect in other ways (such as claiming “preferential servicesâ€). . The recall must be conducted strictly in accordance with the procedures of the recall regulations. The reporter learned that at present, some auto manufacturers in China have a negative effect on taboos from taking the initiative to recall. After discovering defects in the products, they do not report to the competent authorities on their own initiative. Instead, they often call "preferential services" or other names. " Quietly let the technical service personnel of the 4S store solve the problem of product defects. People in the industry believe that although this approach can also solve product defects, it infringes on the public and consumers' right to know and harms corporate integrity. After the "Regulations on the Recall of Defective Automobile Products" formally implemented on October 1, this year, if the enterprise still wants to adopt such an improper way to "pass the customs clearance", it will ultimately pay a high price.
The Tungsten Carbide Roll Rings we produce mostly come in two series: WC Co and WC Co Ni Cr, with Co and Co Ni Cr as binders ranging from 6wt% to 30wt%. From a usage perspective, hard alloy rollers have good comprehensive mechanical properties, with a bending strength of over 2200 MPa and an impact toughness of (4-6) × At 10 ^ 6J/m ^ 2, the Rockwell hardness (HRA) can reach 78~90. During the high-speed wire rolling process, the single groove steel passing amount is much higher than that of cold hard cast iron or high-speed steel rollers.
