Foundry

Batching station

Batching and charging
Completely automated systems for batching of the metallic and additive charge materials for cupola and induction furnace plants are designed and built.
The system computer controls batching of the recipes, calculates corrections and ensures the requested analysis.

Long campaign cupola for shuttle operation

Melting in the foundry
Cupolas with long campaign operation are an economical way of melting in the foundry.
Operation with metal temperatures of up to 1550ºC, high metallurgical flexibility and optimised energy usage through blast heating and oxygen addition are the main characteristics.
KÜTTNER provides a process control system developed for foundries, which optimises operation in regards to quality and cost.
Besides warehousing, material, and recipe organization this system also handles additives and corrective calculations as well as cost monitoring. It is completed by integrated statistical evaluations and an extensive protocol system, which supports record keeping for quality control systems such as ISO 9000 ff.
KÜTTNER supplied cupolas with melt capacities of up to 100 tph. More than 450 cupolas have been built until now.

Shake out with castings cooler

Casting and sand separation and sand cooling
KÜTTNER offers shake out conveyors and drums, controllable shake out conveyors and hooking systems. Careful casting treatment and use of external exhaust volumes for cooling of the castings are main objectives for an economical approach. Solutions are based on vibration technology as well as hanging track cooling and rotating table coolers.
The separated sand is collected, cooled and recirculated into the green sand system for reuse.

Shake out station

Casting shake out and sand regeneration
In foundries with chemically bonded sands the moulds and castings are separated on stationary shake outs.
The sand, having a temperature of up to 600ºC, is buffered, crushed and pneumatically conveyed in an Airlift, which achieves an intense cleaning of the sand particles.
With fine sieve application, Fe-separation, cooling and sifting a superior sand regeneration quality is accomplished.

Foundry planning

Foundry planning
Besides an extensive program of processes, plants and machinery for the ferrous and non-ferrous industry, KÜTTNER plans and coordinates the construction and installation of turnkey foundries with electric and cupola melting.
