Process & plants
1. Casting design
Casting and feeding system design represents the first step in the foundry production process.
L’ACIERIE et FONDERIE de la HAUTE SAMBRE has chosen Magmasoft® software combined to 3D CADSolidworks® to supply our customers a reliable service for casting design and simulation.
2. Pattern construction
Pattern construction in polystyrene – wood or resin is made by our sub-contractors.
Our department carry out on plate adjustment reworking and feeding systems.
3. Moulding
Moulding department performs moulds on chemical process – dimensions maxi 3m600² using silica and chromite sands.
Special layers are used in order to avoid surface recarburation.
4. Pouring
The foundry is equipped with :
- 2 induction furnaces of 2,5 Tons each
- 1 induction furnace of 500 kg
- 1 induction furnace VOD (vacuum oxygen decarburation) with maxi capacity of 4.5 Tons
which allows decarburation and degazing the differents materials made in our company.
- Our laboratory is equipped with a spectrograph 19 elements
5. Finishing
All finishing operations are operated inside the company.
2 shot blasting machines (one ferrite steel shot and one stainless steel shot) and 1 sand blasting CORINDON are used to avoid contamination of differents materials produced.
6. Heat treatment
2 heat treatment furnaces :
- 1 electric furnace 5 T – maxi 1200°C
- 1 electric furnace de 3.5 T – maxi 1250°C
Combined with 2 water tanks equipped with mixing and cooling system and a air cooling system to optimize the alloys quality.
7. Controls
The laboratory is equipped to perform all tests :
- Spectrometric chemical analysis
- Mechanical tests (tensile test – impact test – hardness)
- Corrosion test (SCC – HIC Tests)
- Macro & micrographic tests
Operators certified COFREND I or II :
- Dimensional controls (manual or scan)
- Surface controls (Dye penetrant test –Magnetic test)
- Volume controls (ultra-sonic test – radiographic test)
- Pressure test
