Abstract

The utility model relates to an isothermal spheroidizing annealing thermal treatment device of large metal product forged pieces in particular to large bearing rings which are larger than phi 600mm, in particular to an energy-saving double-chamber multi-roller path large isothermal spheroidizing annealing furnace, a first furnace chamber and a second furnace chamber are arranged in a furnace body, a spaced thermal insulation furnace wall is arranged between the first furnace chamber and the second furnace chamber, and two roller guide tracks at least arranged between the first furnace chamber and the second furnace chamber. The energy-saving double-chamber multi-roller path large isothermal spheroidizing annealing furnace has the advantages of reasonable structure, great yield, high production efficiency, mutual utilization of thermal energy between double chambers and high thermal efficiency, and the multi-roller guide track structure is more applicable to rolling of a large material tray, thereby being capable of spheroidizing and annealing the large rolling bearing rings which are larger than phi 600mm.

Description

The energy-saving double-chamber multi-rollway isothermal spheroidizing stove

Technical field:

The utility model relates to the isothermal spheroidizing thermal treatment unit of a kind of large-scale metal products forging (especially＞Φ 600mm large-scale bearing ring).

Background technology:

Prior art is handled for the isothermal spheroidizing of metal parts (for example high silicon and alloy steel forging in the bearing ring forging), the general two raceway structures of single chamber (single passage) that adopt, and adopt back, two chamber (two channels) heat energy to utilize mutually, energy-saving effect is remarkable, when former pair of raceway props up material bearing disc, to the used big charging tray of heavy froging, the easy flexural deformation of charging tray in use, the balance that influences charging tray in the pusher process is moved reliably.

The utility model content:

It is a kind of rational in infrastructure that the purpose of this utility model is to provide, can make full use of heat energy realize energy-conservation, output is big, productivity is high; Can prevent to be used for the diastrophic large-scale isothermal spheroidizing furnace of big charging tray of large size bearing external member again.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of energy-saving double-chamber multi-rollway isothermal spheroidizing stove, be provided with first burner hearth and second burner hearth in its body of heater, be provided with an insulation furnace wall that separates between described first burner hearth and second burner hearth.

In order to adapt to the large-scale charging tray running that the heavy froging isothermal spheroidizing is used, be many fulcrums form promptly with contacting of each charging tray, described first burner hearth and second burner hearth are provided with 2 rolling wheel guide rails respectively at least.

The utility model is rational in infrastructure, output is big, productivity is high, and heat energy utilizes mutually between two chambers, the thermo-efficiency height, and many rolling wheel guide rails structure more adapts to the rolling of big charging tray, can carry out＞Spheroidizing Annealing of the large-size rolling bearing lasso of Φ 600mm.

Description of drawings:

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the A-A sectional view of Fig. 1.

Fig. 3 is the B-B sectional view of Fig. 1.

Among the figure: 1, first burner hearth; 2, second burner hearth; 3, the insulation furnace wall that separates; 4, rolling wheel guide rails;

Embodiment:

As Fig. 1, Fig. 2, a kind of energy-saving double-chamber multi-rollway isothermal spheroidizing stove shown in Figure 3, be provided with first burner hearth 1 and second burner hearth 2 in its body of heater, separate by an insulation furnace wall 3 that separates between described first burner hearth 1 and second burner hearth 2,2 rolling wheel guide rails 4 (2 or more rolling wheel guide rails 4 also can be set) are set respectively in described first burner hearth 1 and second burner hearth 2, can be many fulcrums form with contacting of each charging tray like this, twin furnace can push away or draw material simultaneously, also can stagger the time and carry out, the big charging tray of many raceways is both applicable to the large product forging, also applicable in the isothermal spheroidizing of miscellaneous goods forging.
