Description

(54) Ingot support mechanism for zone handling melters with variable handling chamber length

The purpose is to absorb the axial force caused by the weight of the ingot being processed, which acts on the nucleus during melting of zone apparatuses of variable length of the handling chamber, while maintaining its design length.

This is achieved by an ingot support mechanism, wherein at least three bars are vertically and slidingly mounted in the body of the protective cup fixedly connected to the rotation shaft of the ingot holder. The blades at the lower end abut the ring, slidably mounted on the auxiliary support, with the separating handling chamber in two parts. The auxiliary support is vertically sliding along the guide rod. The lower part of the handling chamber is closed by a lower support on which is placed a foil, one end of which passes through an adjustable sliding clutch and anchored in the body of the working chamber.

The adjustable slip clutch is located on the auxiliary support.

BACKGROUND OF THE INVENTION The present invention relates to an ingot support mechanism for zonal apparatuses with variable handling chamber lengths.

The support mechanism serves to absorb the axial force given by the weight of the ingot to be applied to the nucleus during the melting process. The support mechanism used up to now intercepts the ingot by means of lever swinging arms, respectively. by means of locking pins extending from a coaxially arranged tube around the ingot.

Another support mechanism uses pull-out trays to the point of conical expansion of the ingot and the subsequent filling of the locking balls.

Said support mechanisms are suitable for large-scale zone devices, their height including bases reaches several times the length of the ingot being processed. These support mechanisms are not suitable for zone devices with variable length of the handling chamber, including the foundations, which are less than twice the length of the ingot being processed.

For zonal apparatuses of variable length of the handling chamber, the ingot support mechanism according to the invention is suitable, the principle being that at least three bars are vertically and slidingly mounted in the protective bowl body fixedly connected to the rotation shaft of the ingot holder.

The lower end is supported by a sliding bearing mounted on an auxiliary support vertically displaceable on the guide rod. The auxiliary support is located in the lower part of the upper part of the handling chamber, which is divided into upper and lower parts.

The lower part of the handling chamber is closed by the lower support on which the foil is placed. One end of the foil passing through the adjustable sliding clutch is anchored in the body of the working chamber. The adjustable sliding clutch is firmly connected to the auxiliary support.

The ingot support mechanism according to the invention allows the processing of high-weight ingots in zonal apparatuses with a variable length or bellows construction chamber.

It fits into the composite handling chamber so that it does not extend its construction length. Allows automatic and continuous approach to the conus read ingot, so there is no danger of monocrystal growth when touched.

In the drawing, a section of a zone apparatus with a bellows handling chamber, with a suspended ingot and an ingot support mechanism is shown in cross-section.

Example

A protective bowl J is fixedly mounted on the rotation shaft 2 of the ingot holder 16. In the protection bowl X, three bars χ are arranged vertically and slidingly, distributed uniformly along the rotation shaft 2 of the ingot holder 16.

The lower ends of the rods X are embedded in a ring 6 which slides against the support slide 8. The auxiliary support 6 is displaceably mounted on a common guide rod of the fi lonic apparatus. Further, a working chamber 4, an upper flange 11 and a lower flange XX of the upper and lower parts 6 and 2 of the handling chamber are located on the guide rod.

On the lower flange of the mining chamber part 2 of the handling chamber is fixed a sleeve X2 in which the foil 11 is wound. The extension end of the foil 11 passes through the adjustable sliding clutch XX and is fixed to the working chamber 6.

During the melting process, the working chamber 6 and the molten zone inductor are moved upwards along the ingot to be processed, away from the embryo 11 clamped in the lower holder,

Also, the lower part X of the handling chamber is lengthened and the upper part 0 of the handling chamber is shortened. By adjusting the driving force on the adjustable sliding clutch 14, the auxiliary support χ is actuated by means of a roll-up foil 13 by pulling on its extension end anchored in the body of the working chamber X.

This is then moved upwards at the speed of movement of the working chamber 2. At the same time as the auxiliary support 1, the ring 6 with the countersunk rods J is mounted thereon. The ring A is made of a material with a low coefficient of friction so that, when the shaft 2 rotates, the rotation of the ingot holder 16 with the protective cup J and the rods J slips smoothly on the auxiliary support 6.

The protective bowl J serves as protection against the dropping of material from the molten zone of the ingot 16 into the handling chamber and at the same time as guiding the bars 1. After extending the bars 1 to a position in which they support the ingot Ji, adjustable sliding clutch 14.

When this value is exceeded in the further course of the melting, the adjustable sliding clutch 14 slips along the foil 13 and the rods J, supporting a defined ingot Ji with which they rotate simultaneously.
