“…The scheme of regenerative burner operation is shown in Fig. 1 [10][11][12][13][14][15]. The specific feature of the regenerative burner is a very high preheating of combustion air, which enables to achieve a high fuel utilization factor up to 90 %.…”

“…As a rule, the ring furnaces are used for heating billets when rolling pipes, wheels and tires of railway rolling stock, for heat treatment of metal products as well as for heating nonferrous billets before rolling and upsetting. The purpose of heating is to get a structure providing the given physical properties and operating parameters or to make these materials plastic, which is required for further mechanical treatment [1][2][3][4][5][6][7].…”

High productivity of rolling and pipe rolling mills, good quality of finished metal products is possible to provide in the presence of powerful heating furnaces, well heating the metal with minimal oxidation and decarburization. Such conditions are provided by ring furnaces which are widely used for heating the preparations at rolling of pipes, wheels and bands of the railway rolling stock. The purpose of the heat – receiving structure of the metal, providing a set of physical and working properties, or impart to these materials the ductility required for subsequent machining. The article deals with the design and thermal performance of the ring furnace operating at ChelPipe’s Pipe Rolling Plant No.2. The problems arising during the operation of the thermal unit are analyzed. The paper describes the calculation of heating of metal and heat balance of the ring furnace. In the course of the analysis of the results of design studies, the shortcomings of the existing heat recovery system are revealed and measures for the reconstruction of the furnace to reduce fuel consumption and increase productivity (replacement of the existing brick lining with fibrous, the use of regenerative burners, the use of non-water-cooled partitions, etc.) are proposed. The paper analyzes the design and thermal performance of the ring furnace for heating of pipe billets before rolling. It shows a heat balance of the ring heating furnace and provides measures for furnace reconstruction aimed at reduction in fuel consumption and increase in efficiency: replacement of the existing lining with fiber lining, use of regenerative burners, application of non-water cooled walls.

“…Generally, the annular furnaces are used for heating of billets when rolling of pipes, wheels and tires of railway rolling stock. The purpose of heating is to obtain a structure that provides specified physical and operating properties, or to impart plasticity to these materials that is necessary for subsequent machining [1][2][3][4][5][6][7][8][9][10][11][12][13].…”
