## Abstract

The invention relates to processes and apparatuses for pushing through/pushing in/turning through/turning in components/linings, as an individual component/section/subassembly for batch feeding/melting furnace/conveying path for the melt/conveying path for other emissions/transportation means for the melt, in that the pushing through/pushing in/turning through/turning in takes places in a manner controlled by means of pushing-through/pushing-in/turning-through and turning-in elements and the corresponding drives or under fully automatic control, preferably observing the maximum permissible compressive and tensile forces of the components/linings of individual components/sections/subassemblies which can be pushed through/pushed in/turned through/turned in in each case, in order to avoid joints in the respective region and to prevent inadmissibly high forces/pressures/traction/torques on the respective components/linings, during a heating operation/melting operation/cooling operation.

## Claims

### Claim 1

A process for the feeding in of materials, melting furnaces, conveying of the melt, conveying of other outputs from the melting furnace and means of conveying the melt, by means of adjustable pressure elements,
characterized in that
a controlled pushing in/pushing through of individual elements (16, 19) or sections or subassemblies by means of the motion elements (43, 46, 49, 50, 67) and the corresponding driving unit (33, 34, 35, 36, 37, 38, 39, 40, 41, 42) takes place.

### Claim 2 (depends on 1)

The process according to claim 1, characterized in that the controlling is fully automated.

### Claim 3 (depends on 1)

The process according to claim 1, characterized in that the individual elements (16, 19) or sections or subassemblies perform a linear motion.

### Claim 4 (depends on 1)

The process according to claim 1, characterized in that the individual elements (16, 19) or sections or subassemblies perform a rotational motion.

### Claim 5 (depends on 1)

The process according to claim 1, characterized in that the individual elements (16, 19) or sections or subassemblies perform a variable motion.

### Claim 6

A device for the feeding in of materials, melting furnaces, conveying of the melt, conveying of other outputs from the melting furnace and means of conveying the melt, by means of adjustable pressure elements,
characterized in that
the motion elements (43, 46, 49, 50, 67) permit the controlled or fully automatically controlled pushing in or pushing through of individual elements (16, 19) or sections or subassemblies by means of corresponding driving units (33, 34, 35, 36, 37, 38, 39, 40, 41, 42).

### Claim 7 (depends on 6)
