“Krasny Kotelshchik” is Improving Quality of Product Heat Treatment
The Taganrog Boiler-Making Works “Krasny Kotelshchik” (TKZ) completed modernization of batch-type gas furnace. The furnace is intended for heat treatment of component parts of the shell-type equipment being supplied by TKZ to various Russian and foreign power plants including nuclear power plants.
Shells & vessels workshop of “Krasny Kotelshchik” specializes in these products. Owing to the modernization of the batch-type gas furnace this production division will enhance the quality of performed operations. In particular, heat treatment operators will be able to carry out a uniform heating of metallic products with a maximum heat treatment temperature equal to 1 150 ºС.
Further to the above, the furnace compliance with the modern safety requirements has been provided, its thermal efficiency has been improved. It was possible to achieve this on account of installation of a central recuperative heat exchanger and lining of the furnace inside surface with new refractories. Also, the furnace was shifted to automatic touch-sensitive control which significantly reduces labor hours for heat treatment of shell-type equipment components.
