Abstract:

 The paper's idea is considering the possibility of using a low concentration of polyacrylamide water solutions as a quenchant for uniform and intensive hardening of machine components and tools. An advanced method of prediction microstructure and mechanical properties of steel in large hardened products are also considered. The idea consists of comparing cooling curves in small probes and large steel components during their quenching. It is assumed that cooling curves are the same if m exponent factors are equal between each other. This new approach provides more accurate prediction as compared with the existing method, which is based on a calculation cooling rate at a temperature 700oC. It is underlined in the paper that primary attention should be paid to software development to govern correctly quenching process to receive essential benefits. The cost of polyacrylamide water solutions insignificantly prevails the cost of plain technical water due to deficient concentration and low cost of polyacrylamide. Customers can prepare polyacrylamide water solutions by themselves, providing appropriate control of quenching processes.
