Abstract

The invention relates to the field of foundry and can be used to cool the cupolas. The purpose of the invention is to increase the reliability of work. Water under pressure is fed through conduit 8 to the upper 2 and lower manifolds. The cavity of the upper collector 2, which is made in the form of a funnel 4, is filled with water, which through the gap 5 is directed to the case 1 of the cupola and flows along it in a continuous uniform flow, cools it, and collects in the sump. An additional portion of cold water from the lower collector is fed into the water flow in the lance area. This is done for the purpose of more intensive cooling of this zone, since it is overheated and the water coming from the upper collector 2 has already partially heated up. The adjustment of the gap 5 is carried out by displacing the sections of the valve 3 along the generatrix of the funnel 4. 2 Il. S (L 4 S71 SL; o oo

Description

The invention relates to foundry and can be used to cool the cupola.

The invention is increased reliability.

FIG. 1 shows schematically the proposed device; in fig. 2 - node I on phi. one.

| A device for cooling the housing 1 of the frame comprises an upper annular collector with an adjustable cone flap 3. Co. | 1 the collector 2 is made in the form of a sonic funnel 4 closed from above, positioned with the bottom edge with a gap 5 relative to the body 1, and conical the flap 3 is made of sections 6 fixed with screws 7 on the outer surface of the funnel 4 with the possibility of moving it forming to regulate the size of the gap 5.

In order to supply water to the collector 2 there is an npi-fastened pipe 8. A collector 2 with a flap 3 is installed in the upper part of the housing 1. In addition, the device contains a Upper collector 9 for directing water to the housing 1 of the cupola in the soHfe 10 and 11. A collection box 12 is installed in the part of the cupola for collecting waste water.

The device works as follows.

Water under pressure is fed through conduit 8 to the upper and lower collectors 2 and 9. The cavity of the upper collector 2 is filled with water, which through the gap 5

sent to the housing 1 of the cupola and flows along it in an equal uniform flow, cooling it, and is collected in a water collector 12. In the water flow in the area of tuyeres 11, an additional portion of cold water is fed from the lower collector 9 with the aim of more intensive cooling of this zone, because it is overheated, and the water coming from the upper collector 2 is already partially heated.

The device allows to simplify the design of the cooling system by making the upper collector 2 in the form of a funnel 4, which forms a closed volume with the body of the cupola 1 having a movable gate -J5 ku 3 to adjust the size of the gap 5, and to increase the reliability of operation, as the effect of the cooling process changes the pressure of the water in the system and eliminates the splashing of water from the funnel 4.
