Description

An electric furnace for heat treatment of products, including kasher, lining, heaters, equipped with a lifting mechanism, retractable under and use of a cooling machine. However, cooling in a furnace with open deers although it allows the cooling rate of the cooling level to be quenched, but results in "not uniform tel'surature in the furnace. It is unequal to measure but is cooled from the divisions at the time of a vykvlvANI hearth.

The proposed furnace is equipped with multi-layered screens separating the lining of the 1m.patcher and from the windows, and a part of the screens is filled in the form of squares located along the wall and fixed to the sections of pipes that pass through | refrigerant when combining pipes with “ala1m. and lining. This makes it possible to increase the productivity of the furnace.

FIG. 1 until: on the proposed furnace, longitudinal section; in fig. 2 and 3 - the same, with lowered (three heating) and raised (LRI cooling) SHI: bvramI.

The electric furnace contains a stationary futures chamber 1, | VY1D | V (an example of 2, moving 1PA to the rails on the headers. Using the mechanism 1. 3 movement, the door 4, covering the open opening of the chamber 7, l mechanism 5, podmv1a. The door can be

not lifting and fixed permanently or pivotally on the hollow.

On the vertical walls of the lined chamber, on the door and the standout;

On the walls, l) Veri and the gadfly, stationary and movable multilayered E | Cranes, made of thin metal of YOUR metal, are installed. Statsnona rshI are made of iloaky verti cal 7 and 5 and horizontal 9 and 10 e / cranes.

iB, between the vertical screens 7 and S, pipes 11 are installed, connected to a fan with another INSTALLATION SYSTEM for supplying the hloschonositel.

At the junction of vertical (7 and S) and horizontal screens (at the chamber arch), there are optional screens, made in the form of separate sections 12. The number of sections may be different and depends on the length of the furnace. In the inlet section (D t external 13 and internal 14 screens having the shape of corners and connected to each other (for example, pr (HELP studs)).

 The section is fastened on two pieces of pipe 75. One end of the segment passes through the holes in the shield; x 13 and 14, to which it is welded, D (ruddy end goes through the lifting lined 16 and immobile / fixed in it.

The gate of 16 pairs shifts (rises and discharges) in | Vertier (ballroom).

iB in its lower floor, the re-KipbiiBiaeT horizontal gate is horizontal; b, located in the latest lining layer of the chamber. The channel b has the same cross-section with the section of the pipe 15, and its axis passes between the screens 9 and 10. To the channel is b ooeAHiHeHbi of the pipe 17 for removal of air from the furnace. On the chamber roof there are fans 18, the impellers of which are placed in p-rostran ST; the range between sKipa.HaiMH 9 and 10.

On VYDV.IZH1NOM Pada, the trellis pods 19 are loosened and the products 20 are placed on them.

The kiln operation is carried out in the following sequence.

Sliding under 2 is out of chamber 1. There is a load of g1Division on supports / B-pod 19. The door 4 and the door are opened with (the task is rolled into the chamber /. Then D (trust the player. The gate 16 is in the lower position. At this point, the sections of screens 13 and 14 lie respectively on SKipaHax 9 10. Channel Both ends of pipe sections 15 are framed on one side by an outer lining layer with a friend - external stationary siKpaHOiM 7. Fans 18 and heating elements 6 are turned on. Thanks to the rasa directional circulation, heat is transferred intensively from: to: Delhi m and fast heating .

The air circulating: in the furnace, while moving from the fan between e: cranes 9 and 10, screens 13 and 14, the lining and the screen 7. Then it washes under, stands and products and sucked by the fan.

At the end of heating and holding at a given temperature, the heaters are turned off. And the gate 16 rises. In this case, the gate is established in such a way that the axes of the pipe 15 and the channel b are the same; The horizontal section of screen M is wiped into Eyuran 9, and the vertical section 1 with the entire lower part lies on screen 7, not the circulating gas to the heaters and foot (equal to: ke.) Cold air is introduced into the space between E1 screens 7 and S. screens 7

and 5, it moves with hot air circulating in the furnace, then it washes under 2, sub 19V, product 20 and moves towards the fan.

Further, the air passes between screens 9 and 10 and ehedron.m 14 is directed into the space between screens 7 and 5.

A part of air (by weight equal to the amount of hot air, c (wi-fi into the furnace through pipes 11) through pipes 15, channels b and pipes 17 is ejected from the furnace. For cooling equilibrium cooling is equal to (i), more than the amount of cold air injected through pipes // into the furnace in 1 hour.

In the process of cooling, the cold air moves in the space between screens 9, 10, and 7 S and does not come into contact with the lining.

This allows you to cool the product without significant cooling of the lining (especially at low temperatures), save a part of the aumulator thermal masonry for subsequent QI | KL01V and significantly increase the cooling rate of the products. Using the amount of cold air introduced into the furnace, it is possible to vary the rate of cooling of the products in the wide limits.

At the end of the cooling of the products, the supply of cold air to the furnace is stopped, the hooks are lowered and the door is stopped. Then, under the roll out of the furnace, the door is lowered. Unloading of processed products and loading new ones. repeats.

Prevention of Invention

Electric furnace for heat treatment of products, including KaiMepy, lining, heaters,

gates equipped with a lifting mechanism, a movable platform and a device for supplying refrigerant, characterized in that, in order to increase the productivity of the furnace, it sleeps with multilayer e-specks, one of

(which are made in the form of squares located along the side walls and fixed on the cut section passing through them and on the gate valves (pipes for discharge of the coolant when combined and pipes with channels of footguards.
