Description

one

The invention relates to furnaces for the heat treatment of special products and can be applied, iadr, to heat the hardening of the rolling rings.

A device is known for heating products, which are bodies of rotation, for quenching, containing an induction electric furnace and an electric resistance furnace sequentially arranged during the process. Transportation of products through the working spaces of the furnaces is carried out by taltings: they are equipped with a special pusher;

However, when moving the heated products inside the furnace, the rings and 0 are purchased; the shaft, for the elimination of which it is necessary to leave large grinding allowances, which increases the cost of processing.

The purpose of the invention is to prevent the products from being soaked.

This is achieved by the fact that the device contains a guide for moving zzel. S, consisting of two parts, one of which is made stacked. The guide represents the lower part of the unit chamber sealing the working space of both of them. In this case, maneuvering

A gutter consists of two walls that are angled to each other. One of these steno K has st} -ienp, made oblique. At the end of a single sealed chamber, there is a discharge device, at the initial part of which there is an orientator in the form of a stop for the upper part of the products. The lower part of the discharge chute is designed as

product guide.

FIG. 1 shows a device in advance; iha f-ig. 2 - camera, longitudinal section; in fig. 3 - the same, across the cut.

The device contains an induction electric furnace 1 and an electric resistance furnace 2, preferably located along the process. Both furnaces are connected as one unit by chamber 3, sealing their working space. Lower part of the sealing part

The chambers are installed in a portable chamber for moving the products inside the furnaces, made in the form of a groove consisting of walls 4 and 5. The wall 4 of the guide channel is flat and flat, mostly 2-40

At the beginning of the parts, part of each wall section 5 is at the same level.

with wall 4. Zaghem wall 5 constantly rises and when it reaches a certain height, it cuts off to form a step 6. In addition to the Bottom, made as a sore, the chamber also has an upper part 7, which | В: in the place with Pizhiya 1 seals the working space dinners stoves, image muffle. Thanks to a single sealing chamber, the working space of induction pechi 1 and electric furnaces with counter-electric resistance 2 are integrated into one whole. There is an unloading chamber at the anti-sharpening end of the camera (Noah device 8 with an inclined chute 9, the lower part of which consists of directing signals for products falling in an oriented position. At the initial discharge area there is an orientation device installed in the first type of stop 10. The end of chute 9 is immersed ; In quinea 11 with quenching liquid, forming a hydraulic shutter. Chute 9 can be made detachable The device works as follows. Products 12, for example quality podshitsikov rings, are fed by a loading device pusher in the initial portion of the single sealing chamber 3 and moving along it, the passage successively induction electric 1, where about: neither is heated to the temperature of the quenching temperature, and electric furnace sop: contraction, where they are held at the quenching temperature to complete the phase transformations in steel. In addition, the product chambers 3 are supported on the walls 4 and 5 of the lower part of the chamber. The products roll under the action of t HiecTH until it touches the initial part of the next section of the wall 5, while turning around the axis to some degree. Each successively all the towers located along the length of a single chamber 3, each product rotates at a minimum angle of 90 ° in sum, which makes it possible to avoid the formation of an ovality of the product. After reaching the unloading chamber of the single sealing chamber, the product rests with the upper part against the support 10 of the orientator and, in an oriented position, slides along the groove 9 onto the coivayer 13 of the spring bath //. The subject of the invention is a device for "heating up parts, comprising an electric" induction furnace and a device for transporting products, characterized in that, in order to prepare for the oxidation of products, the device for their manufacture is designed as a guide, connecting and educational and electric furnaces. into a single sealed chamber and made in the form of a chute consisting of walls arranged at an angle to each other, one being made of walls with successively arranged steps.
