SU406885A1 - DEVICE FOR DESTRUCTION OF REFRACTORY LAMINATION OF EXHAUST GUTTERS OF METALLURGICAL FURNACES - Google Patents

Description

one

The invention relates to the field of ferrous metallurgy, in particular to devices for the destruction of the refractory lining of the exhaust chutes of metallurgical furnaces, for example, the main chutes of blast furnaces.

A device for destroying the lining of exhaust chutes of metallurgical furnaces is known, which contains a movable lornus with cutting teeth, the cross-sectional profile of which corresponds to the profile of the chute, and a vibrator with a drive installed above the cutting line.

The disadvantages of a lime device are its low productivity and considerable maintenance labor.

In order to improve the performance of the device and ensure its servicing, the proposed device is provided with a spring-loaded flow guide, with a support connected to the casing made in the form of a concave towards the edges of the intake container. In this case, each upper cutting tooth protrudes above the pizhelement at a height of between their cutting edges.

Fig. 1 shows the proposed device, an obi1II type; in fig. 2 and 3 - the same, cut along the AL and view along arrow B.

The device consists of a frame / with a vibrator 2 rigidly fixed on it, the housing 3, made in the form of CONFINED in the direction

the movement of the intake tank with rezizpishn teeth 4, podpruzhii and Sh11 guide support 5 and the drive flexible 6.

The device works as follows.

If it is necessary to replace the worn out blades of the main chute of the blast furnace, install the device in the chute. Turn on the water of the vibrator 2, rigidly attached to the frame / above the cutting edge and the teeth - /. In this case, the cutting teeth destroy the lining and are inserted into it, and the front part of the frame is supported; The perimeter of the housing 3 with cutting teeth corresponds to the irofil and the shaft. They include the water of the flexible element (i, non-repetitive devices along the gutter. Vertical teeth. The teeth are adjacent the lower ones to Va heights between the two; It is collapsed from the action of the spring vibrator on the surface and accepts the tilting moment created by the driving flexible element 6 i slippery along the rotary lining of the runner and guides the device along it from the cast iron tap to the bridge crane area: since it is released from the load, since the angle between it and the verticals exceeds the angle of repose.

The subject is invented and

A device for the destruction of the refractory lining of the outlet grooves of metal furnaces, comprising a movable housing with cutting teeth, the cross-sectional profile of which corresponds to the profile of

chutes, and a vibrator with a drive mounted above the cutting teeth, characterized in that, in order to increase the performance of the device and facilitate its maintenance, it is provided with a spring-loaded guide support connected to a housing made in the form of concave cutting edges intake capacitor, and each upper cutting tooth protrudes above.
