Abstract

The invention relates to the field of ferrous metallurgy and can be used in heating wells, working with liquid discharge, for example, in regenerative heating wells. The purpose of the invention is to increase the term of slutkby. The device for draining the pshak from the heating well contains a chute consisting of 1 lined and 2 parts non-lined, mating at an angle of 86-96. The non-lined part 2 of the gutter is located along the thickness of the bottom, and the lined part is located in the bottom of the 3 chambers of hedgehogs

The invention relates to ferrous metallurgy and can be used in heating wells operating with liquid slag removal, for example, in regenerative heating wells.

The purpose of the invention is to increase the service life of the device.

The drawing shows the device, a longitudinal section.

A slag discharge unit discharges a chute consisting of lined I and non-lined. 2 parts mating at an angle of 86-96. The non-lined part of the chute is located in thickness, and the lined part in the as-not 3 is 460-640 mm thick with the combustion chamber 4, equipped with a burner 5, which is inclined from the vertical axis to the junction of parts 1 and 2 of the chute tap hole 6 is connected to the working chamber 7

well

The device works as follows.

Slag from the opening 6 of the working chamber 7 of the heating well by gravity flows into the lined part 1 of the gutter. Due to the operation of the burner 5, the temperatures in the combustion chamber 4 are sufficient to ensure the liquid mobility of the slag. Pass the lined part 1 of the gutter, the slag through the non-lined part 2 enters the slag ladle. Due to the inclination of the burner 5 towards the interface between the parts 1 and 2 of the chute, the temperature at the exit from the combustion chamber is sufficient to prevent the formation of slag build-up at the exit from the combustion chamber. The junction of the gutter parts at an angle of 86-96 ° to each other prevents the accumulation of slag on the non-lined part of the gutter. Due to this, the slag as it accumulates is freely removed from the working chamber 7 of the well. This structure will ensure operation for a long time without repairing 1, ill., 2 tab.

The bottom of the well chamber is buried in the ladle, and the slag letting out has a significant service life and practically does not require labor costs for its maintenance.

Under comparable conditions, a check was made of the selected design parameters of the slag tap.

Table 1 shows the performance of the tap-hole depending on the angle of inclination of the burner.

As can be seen from Table 1, the received interval of inclination of the burner from the vertical axis of the 3-4 axis is optimal.

Table 2 shows the results of testing the tap-hole at different angles of conjugation of the lined and non-lining parts of the gutter and the angle of inclination of the burner 3 ° .. -The data of Table 2 indicate,. 5 rationality of mating parts

gutters at an angle of 86-96.

At the angle of inclination of the burner 3 and the angle of conjugation of the parts of the gutter 90, the thickness of the bottom of the Burning chamber is 0 NIN, 3, 5, 75, 640 and 805 mm. When the bottom of the combustion chamber is 345 mm thick, its rapid burnout occurs (after a month of operation). With a bottom thickness of 805 mm, difficulties appear in the installation under the chute of the slag ladle, and the consumption of refractories increases.

The remaining devices for the discharge of slag from a well with a bottom thickness of 0 460, 575 and 640 mm are operated for three months and never require repair. Their condition indicates that it is possible to work for a long 5 times.
