Ceramic wire drawing rings are made of solid zirconium oxide. Unlike any steel rings they may be subjected to multiple regenerative grinding. Ceramic rings are recommended for installation on the average car, fine and superfine wire drawing. According to statistics, about 10% of machines a rough drawing and working with rings made of ceramics. Ceramic rings can be used for drawing clad wire, galvanized: galvanized, silver-plated, leaded, etc. Recommended use of zirconia rings: When mounting / dismounting ceramic wire drawing rings required caution, as the ring relative fragility. Do not simultaneously mixed-use rings of different types (ceramic and metal) on the same drawing machines. Compliance with the temperature, precluding expansion or loss of properties of coolant (fimitola).
Compliance with alkaline-acid balance (P / N) and the use of filtering systems coolant. To ensure continuity of production recommended to have stocks of the rings at a rate of 1 / 3 of the number in use in the workplace. The advantages of ceramic ring: Increased wear resistance compared with steel wire drawing rings and the possibility of multiple polishing the working surface. Long service life (by 5-7 or more times longer than steel, depending on operating conditions). Environmental safety in production (no appropriate application of spraying).
