Description

The invention relates to heat engineering, in particular to heating and thermal furnaces, and can be used in the metallurgical, automotive and other industries of the industry.

The purpose of the invention is to improve the quality of heating the workpieces while reducing energy costs and increasing productivity.

Fig. O-1. Depicts a pass-through heating furnace, a longitudinal section; Fig, 2 - diagram of the operation of the oven 40 ° and more than 45 °

With an angle of less than 4U, and more than hr; in fig. 3 shows the operation of the furnace when the burners tilt at an angle of less than 30 ° and more than 35.

The heating furnace contains a working chamber 1 with insulation 2 of fiberboard (BHP). Pipes 4 are formed with a press (not shown) and tube burners 5 are mounted on both sides, with each press its plane of symmetry, with the burner axes located at an angle of 30-35 ° to the surface of the core5 and the plane passing through the points of intersection of the axes of the burners with the surface of the core is 40--45 ° with a plane normal to the core and passing through the beginning bend that part of the horn-shaped core.

On the horn-like cores 3 up to the line of the beginning of the deformation, cold billets of pipes 4 of a certain length are put on. Then, the burners 5 of the heating device, installed in the insulation 2 of the working chamber 1, are ignited. As the deformed part of the horn-like core heats along the press with the help of a press, the workpiece is pulled, and the proposed location-. Burner design ensures optimal heating of the workpieces. The drained outlet falls from the horn-shaped core. The process of tapping is performed continuously for the invention.

A pass-through heating furnace, containing a lined working chamber with burners, in which are horn-shaped cores for stretching pipe blanks, so that, in order to improve the quality of heating of the blanks while reducing energy costs and increase in productivity, the burners are located on both sides of each core in the plane of its symmetry, and the axes of the burners are at an angle of 30-35 to the surface of the core s and the plane passing through the intersection points of the axes of the burners from the top of the core is an angle of 40-45 with a plane normal to the generator of the core and passing through the beginning of the curved part of the horn-like core.
