21 11月 Casting Thimble

AdTech’s main parts of Hot-top casting :

• Casting Thimble
• Transition plate
• Distribution Plate
• Graphite Ring
• Distribution launder

Advantages:

1. High hardness, high erosion resistance, high geometric precision, low maintenance cost, smooth surface;
2. Non-peeling off, non-pollution to molten aluminum and it is obviously improve quality of aluminum alloy;
3. Good thermal shock resistance, reduce the pollution to molten aluminum  for corrosion resistance casting;
4. It’s excellent to use with BN, can be used for 450-800 times casting, energy saving.

The comparison before and after using Casting Thimble and distribution plate:

Instructions of hot-top casting series:

1. Choose the right size parts to install in hot-top casting equipment.
2. The distribution plate, Casting Thimble, transition plate, distribution launder and graphite ring install above the platform, and Casting Thimble, transition plate, graphite ring below. Ensuring the product smooth, clean, undamaged and seamless and it is better to sealed around the side and bottom with ceramic fiber blanket or ceramic fiber paper for thermal insulation.
3. Preheat the hot top casting platform uniformly to 260℃-350℃ after installation completed. If electric heating is not available, heat it by flame is recommended to get rid of adsorbed crystal water. Direct fire on the lining body is prohibited.
