WALL RAMMING MACHINE



Description

It is used for wall refractory ramming operation of coreless induction furnaces. Furnaces, which have different capacities , can be rammed by only one machine with adjustable piston working diameter. Spring – loaded mechanism allows to ram conic formers. Standart products such as 2 pistons, 3 pistons and 5 pistons machines allows ramming from 500 kg. to 40 ton capacity induction furnaces. Special productions are available for greater capacity furnaces.

Advantages

- Compacts refractory material with equal density which causes similar melt penetration on inner surface of refractory.
- Remove risks such as cracks and gas pockets on refractory.
- Completes ramming operation in a very short time.
- Extends life of refractory.
- More melting done with the time saving.
- Manpower is used more efficent and economic.
- Suitable for use in low capacity furnace.
- Operation is done fully automatic with adding automatic crane device.
- 100% service guarenteed, Turkish product.

Working principle

When bottom ramming operation is completed, refractory former is placed into the middle of furnace. Wall ramming machine adjustment bolt is disassembled and machine working diameter is made suitable for operation in former. Refractory is filled in layer by layer and refractory is de-aired with fork tool between layers. Machine is hanged on the crane, pin locks holding the pistons are pulled off, machine is placed down into former. On account of ramming operation start from the lower part of the wall, machine is left hanging in the air with several cm away from the bottom and airflow is provided. It is started with 2 bar and pressure increase up to 4 bar. When operation starts, pistons will stroke to former, at the same time machine will turn around its own axis. For effective strokes, distance of pistons to former should be adjusted very well. Strong strokes will make machine turn around its axis. Wall refractory ramming operation is continued with machine is lifted up step by step 10 cm intervals. Determination of ramming time may be different depends on refractory material properties and terms of use so this value is indicated by operator. Operation is continued with adding refractory material when necessary. Wall refractory ramming material is stopped when its position is 10-20 cm to furnace mouth. Refractory ramming operation which is on the mouth of furnace is completed manual. F.R.L. unit should be used at the entire refractory ramming operations.
