    The invention relates to equipment for the chemical heat treatment of parts from metallic materials in a controlled atmosphere.
    A known device for heat treatment of products, containing a number of technological units placed on the same line, and located along the front of the nodes is a loading (transporting) airtight common to all nodes tunnel with loading and unloading lock chambers adjacent to the specified tunnel, respectively (USSR author's certificate f 443923, C. C 21 D 9/00, 1969).
    A disadvantage of the known solution is the impossibility of operation of the installation units with different atmospheres, in addition, all the nodes are rigidly interconnected. And closed in the total volume, which makes the installation less flexible and difficult to maintain.
    The purpose of the invention is to reduce the flow of protective atmosphere and simplify maintenance.
    The goal is achieved by the fact that in an installation for heat treatment of metallic materials containing at least one arranged in a line, at least one chamber heating furnace with a damper, a quenching bath, a loading area, a mechanism for transferring the processed material to the technological positions of the installation and a source of controlled atmosphere, connected to the technological positions of the installation, the mechanics of the transfer of the material being processed is made in the form of a manipulator with a fork forks, the chamber furnace damper, quenching The anna and forked grip are enclosed in independent protective covers with inlets on the lateral front side, and in the intervals between the furnace and bath loading section, reflective plates are installed, having controlled atmosphere inputs and dispensing tubes arranged fanlikely to create a gas or flame curtain, while the entrance the openings of the casing, the flaps and the casing of the quenching bath are located in the same plane, and the inlet of the protective casing of the forked grip is located in close proximity to the plane ti accommodating inlets damper housings and tubs.

    FIG. 1 shows a chamber heating furnace with a manipulator, a section, FIG. 2 - chamber heating furnace, quenching bath chamber (horizontal section) and loading grid (top view), which are installed in one line, parallel to the track of the manipulator moving along this line; in fig. 3 - the end of the chamber heating furnace, to the sides of which the reflective plates are attached, the end of the quenching bath with a chamber casing and the loading grid; in fig. 4 - reflective plate, side section.
    The installation consists minimally of one chamber heating furnace 1 (Fig. 2 and 3), a quenching bath 7 with leather of chamber type ear 6 and other technological devices, for example a loading grate 13 located in one line, and at least one manipulator 8 moving in parallel this line. The chamber heating furnace 1, heated by heating elements 22, has doors 2, controlled by a lifting device 24 and located in a protective casing 3, the inlet 4 of which has an end face 11 in the same plane as the front side 12 of the inlet 5 of the casing 6 quench bath 7. In the casing 6 of the chamber type quenching bath 7, there is a nitrogen inlet 21 and a smoke outlet 20. The inlets 4 of the chamber heating furnace 1 and 5 of the quenching bath 7 are fitted with fan-shaped flame or gas tubes 15. On the other hand, the chambers A heating grid 13 is placed in the heating furnace for loading the charge 25 (FIGS. 2 and 3). On each side 11 of the end of the inlet 4 of the chamber heating furnace 1 in the same plane with the end 11 there is attached a reflective plate 14 having an inlet 17 of the controlled atmosphere and a tube 16 for forming a flame or gas fan (Fig. 4).
    The reflective plates 14 practically fill the space between the loading grid 13 with the charge 25 and the chamber heating furnace 1, as well as between the latter and the casing 6 of the quenching bath 7. The receiver 18 is designed to remove gases
    19. Parallel to the line of the loading grid 13, the chamber heating furnace 1 and the casing 6 of the quenching bath 7 moves along a stationary path (Fig. 1 and 2) the manipulator 8, the forks 9 of which are located in the protective casing 10, and its inlet 26 is located near face side 11 inlet
    4-chamber heating furnace 1,
    and also the end of the 12 inlet
    5 chambers 6 quenching bath 7 (Fig 1 and 2). Under the close arrangement of both inlets 4 and 5, the minimum technologically feasible distance is podralauma, in necessary cases, the gap between the two inlets 4 and 5 can be blocked with a suitable casing of a known design. The manipulator torus 8 has an observation hole 23.
    The proposed installation works as follows.
    The manipulator 8 receives the charge 25 from the loading grid 13 and in front of the reflective plate 14 or in its protective casing 10 is washed with a suitable controlled atmosphere. The evaporating gases through receiver 1B exit through outlet 19. After that, the charge is introduced into the chamber heating furnace 1, where heating or thermochemical treatment takes place in a controlled atmosphere. After that, the manipulator 8 transfers the charge 25 to the chamber 6 of the quenching bath 7, where it is immersed in oil and tempering using its own mechanism. When transferring the charge, the reflective plate 14 prevents heat from the charge 25 from escaping, and, in addition, through the inlet 17, a controlled atmosphere is introduced into the protective casing 10 of the manipulator 8, which prevents the charge 25 from unwanted reactions with the air.
