The nitriding furnace is a surface nitriding furnace, and the surface nitriding makes the surface have a certain hardness. Nitriding furnace chemical heat treatment refers to a heat treatment process in which a metal or alloy workpiece is kept in an active medium at a certain temperature, so that one or several elements penetrate into its surface layer to change its chemical composition, structure and performance.

ROCHO offers a wide range of pit type electric resistance furnaces, hardening furnaces, annealing furnaces, tempering furnaces for various heat treatment applications, with high quality and and thermal efficiency. 

ROCHO technical team investigated the use of water as a quenching and cooling medium to develop a heat treatment process for 42CrMo seamless tubes and to provide a continuously operating, highly automated seamless tubes quenching line that would increase throughput and improve process results.

ROCHO provides the optimal processes and high-performance heat treatment equipment to meet the requirements of high efficiency, low consumption, light pollution and high automation.

Tin bronze alloy is bronze with tin as the main alloying element. The tin content is generally between 3 and 14%, and it is mainly used to make elastic components and wear-resistant parts. ROCHO provides tin bronze melting processes, and tin bronze induction melting furnace, equipment repair and parts replace, coil repair facilities, and installation services.

ROCHO INDUCTION offers different types of steel melting furnaces, medium frequency induction furnaces, flat furnaces, electric arc furnaces and ladle refineries, to suit the different output and technical requirements of our customers.
