SU1444609A1 - Arrangement for immersing charge under the layer of covering flux and slag in induction furnace bath - Google Patents

Abstract

This invention relates to metallurgy, in particular to secondary non-ferrous metallurgy. The purpose of the invention is to simplify the design of the device. A device for immersing the charge under the layer of coating flux and slag in a bath of an induction furnace includes a body, a vertical axis mounted on it, a console attached to the vertical axis, a plunger fixedly mounted on the console, a mechanism for reciprocating the plunger vertically. The console is connected to the vertical axis by means of a joint with the possibility of swinging in the vertical plane up and down from the horizontal position, and the length of the console to the magnitude of the stroke of the pusher must be at least 5. The design of the device is greatly simplified by replacing the complicated and cumbersome back-return mechanism translational movement of the pusher vertically. 1 hp f-ly, 3 Il. with S (L

The invention relates to metallurgy, so that the pusher is above the vanities can be used on the electric in the right place, after which the force

cus induction furnaces in a color me-cylinder 10 (manually controlled) of metallurgy, mainly in the secondary console 4 with a pusher, and

nonferrous metallurgy. the value of the lowering of the pusher 1 is determined

The aim of the invention is to simplify depending on the level of the metal in the furnace,

device design. so that in the process of immersing the bottom

FIG. 1 shows a device, the type of pusher is immersed in the melt, then

ku; in fig. 2 - view along arrow A is connected to the power cylinder 10 on the reverf. one; in fig. 3 - scheme of work tol-sivnuyu work in automatic mode

Katel vertically. Yu with a constant course. For immersion

The device for immersing the solidified bottom of the entire bath surface. - duction furnace 2. Pusher using roystva 9.

the hinge 3 is fixed at the end of the console 4 with waste materials (consisting of swinging scrap and waste in the plane of the consolidated raw material group. The console 4 by means of the 5-colored metal and alloys joint), which are attached to the lugs 6 of the vertical furnace, are above melt. When the axis 7 moves with a possibility of swinging up and down, the lower end of the pusher rises up the ticking plane up and down from the go-20 above the ground, and during the downward movement the pusher of the horizontal position, with the butt end capturing a certain portion of my console length to the stroke value It should not be less than 5. Verti-layer of coating flux and slag. The mixture, the shaft axis 7 is rotatably mounted with a quenched liquid metal, does not float up to the sleeve 8, rigidly fixed to the side and quickly melts, with a significant increase in the wall of the charging device 9, the productivity of the furnace, which decreases moving along the rail track, increases in color metals, economite-bake site of the furnace (in the case of the absence of electric power and more efficient use of the charging device, moving the fluxes.

state on the working platform of the furnace, the sleeve 8B of the proposed device, the oscillating can be mounted on a special (pivoting) movement of the console converts the bed). The cantilever is rotated vertically in a reciprocating motion of the plane by a vertical cylinder of the push rod. rum 10 (hydraulically or pneumatically — in Fig. 3 are indicated: H in size), the brush of which pushes the pusher hingedly along the vertical from the beginning to the console 4, and the casing to the end of the melting (working bracket 11, fixed) pusher); h is the thickness of the maximum-lower end of the vertical axis 7. Of the layer of blended materials over the expansion of the console 4 in the horizontal plane of the melt (during the smelting process, the metal level is carried out by the power cylinder 12, the furnace rises in a furnace krivoscha-metsa and the level of zashchishchitta in the furnace); PU 13, rigidly mounted on vertical-Hi, is an additional stroke of the pusher, axle 7, and the housing is directed to the trunnion 14, which is necessary for pushing the pusher into the furnace attached to the charging device 9. and withdrawal from the oven (kinematic stroke).

Hydraulic and electrical circuits The size of the automatic movement of the plowing device is made according to the type known, l must be slightly greater than h.

ensure the operation of the power cylinder 10, at a certain ratio, the length of the hand-operated konkak and of the auto-salt L to the course of the pusher H (working

tical reversive work with a given approach) arc of a circle, described by the end

by a constant stroke of a pusher console, which is hinged on

The remote control device. The pusher will deviate a little from the top. All elements of the device can be out of a ticking straight, and the pusher will be re-prepared from the usual constructional elements to move reciprocatingly and also materials using typical products-50 to deviate a little from the vertical straight. LI. For normal operation of the device

The device works as follows. It is necessary that the ratio of the length of the consoil cylinder 10 raise the cantilever L to the thrust pusher H was not metal 4 to the extreme upper position, less than 5. With a smaller ratio of this length, the bottom of the pusher 1 was lifted by -L consoles N pusher to move, pushing higher than the furnace loading window, for-55 at the accepted frequency of cycles we will turn console 4 to horizontally to swing and there will not be a vertical cylinder with a power cylinder 12 - and move boot triad 9 will go sideways by turning

relative to the hinge mixture in the melt.
