Increasing performance of steelmaking units is possible with changing methods of steel production. Such variances entail serio us changes in the subsequent redistributions: in metals processing by pressure and in thermal treatment of finished metal products. It is known that these two metallurgical processes are equipped with a large number of heating and thermal furnaces, and their thermal work does not always meet increased requirements for products quali ty. Issues of improving thermal performance of furnaces are also relevant in mechanical engineering. High technological requirements are associa ted with very strict environmental ones. Therefore, a new concept is needed for the design and construction of modern highly automated industrial heating furnaces. In order to improve the design and technical and economic indicators, technical obsolescence and the construction of new industrial furnaces are carried out. In design and construction of furnaces, fuel-burning devices of new designs and modern materials are used. In turn, this necessitates the use of new approaches to working space and heating system design of the furnace, taking into account arrangement of heated products charge. Such events are carried out, as a rule, in operating workshops, that causes certain difficulties due to limited space provided for placement of new furnaces and equipment for their operation and maintenance. A complex study was made of the design and thermal performance of a block of three chamber thermal furnaces. They were built in a limited space of the workshop with specific loading and delivery of heated thin sheet.
