The invention relates to non-ferrous metallurgy and can be used to melt someone in a suspended state.

According to the main author. St. jVo 819544 known melting chamber, containing a vertically located, cylindrical-conical body, a loading nozzle, an oxygen nozzle and a nozzle for unloading melting products, made in the form of a Laval I nozzle.

The disadvantage of such a melting chamber, whose walls are cooled with water, is the possibility of burning out the comic part when melting shih.ht with a high (600-1000 kcal / kg) calorific value due to the high (350-500 thousand kcal / mh) thermal capacity of the walls.

To ensure the operability of the burners and melting devices, it is usually used either the method of spiral cooling of the walls with water, or the formation of garnssage on the coffered surfaces due to the usual flow of water.

However, the spiral method of water flow to cool the walls is complicated in design, especially for large-sized devices, and requires a large water pressure (2-4 atm) to provide a flow rate of cooling water of at least 4 m / s.

The usual flow of water through caisson devices is provided with insufficient heat loss from surfaces (less than 200-300 thousand kcal / mh) at (high heat output with high calorific value, as a result of which water in the stagnant zones goes to boiling with formation of steam Mep1kov and occurs iporap the hull wall.

The aim of the invention is to increase the service life and reduce water consumption.

The goal is achieved by the fact that the caisson wall of the small chamber is equipped with a perforated partition at its lower end, placed in the cavity of the caisson wall, and ribs are made on the firing side of the wall.

FIG. 1 given melting chamber, general view; in fig. 2 is a cross section. LN FIG. one; on ({) ig. 3 - perforation.

The melting chamber contains cylindrical 1 and conical 2 parts of the body, a pipe 3 for discharging melting products, a cover 4 with an integrated nozzle 5 for supplying oxygen and an incendiary device 6. Caisson wall of the chamber body and has cavities for supplying 7 and discharging 8 water, divided) The first are a partition 9 with perforations 10 for uniform distribution of the water flow over the working surface II, on which the longitudinal ribs 12 are located.

between adjacent ribs 0-20 mm. The contact of the ribs with the firing wall is provided by a solid one-sided welding seam.

J The melting chamber works in the following way.

When the charge is burned in the cavity of the melting chamber, intense heat exchange occurs between the hot products and the chamber steaks. Cooling water

The walls are supplied with a pressure of 1.5-2 atm through the nozzle 13 into the supply cavity 7. Due to the perforation 10 in the lower part of the partition 9, which separates the cavities 7 and 8, water enters the heat-release zone through a continuous flow. The even distribution of the flow and the presence of the longitudinal ribs 12 cause the water to flow at the same speed I1 of the firing wall i, heats and removes heat from the wall, lowering the temperature and temperature.
