Refraco designs and fabricates the following components for foundries:
- Furnace Head Blocks
Refraco fabricates pre-cast blocks to protect the upper ring of induction furnaces. These blocks facilitate cleaning and can be easily replaced reducing maintenance time.
Induction spouts are usually formed in place using refractory plastic. Refraco has developed pre-cast spouts with high wear resistance that last longer, are easy to clean, and are easily replaced.
- Induction Furnace Covers
Refraco lines induction furnace covers with multiples layers of refractory concrete and insulation to provide energy efficient and safe equipment.
- Induction Furnace Bottoms/Plugs
Refraco fabricates pre-cast tiles to line the furnace bottom.
Grey Iron Ladles
Traditionally, grey iron ladles are lined with a rammed refractory plastic or cast-in-place refractory concrete. The problem with these traditional linings is that it is difficult to fire them properly and they therefore lack homogeneous properties.
Refraco fabricates pre-cast spouts and entire liner tiles for the ladles. The combination of the material selection, and the fact that these parts are pre-fired, results in a liner with higher mechanical, thermal shock, and wear resistances than traditional linings. Our parts last longer than traditional linings.
Emergency Dumping Bin
In the case of a loss of control on the induction furnace, the molten cast iron must be dumped rapidly. Emergency bins are lined with refractory to receive the molten cast iron so-dumped. Refraco designs pre-cast liners for these bins that better withstand these extreme operating conditions.
Floor tiles are applied to all zones that are capable of receiving thermal and mechanical shocks. Whether it’s under crucibles, drainage pans, or in front of a furnace, these tiles are fabricated using a material that is extremely resistant to wear and thermal shocks.
