Aluminia Refractory Main Runner Manufacturers in India
The main runner is a part of a bottom pouring set used in the ceramic casting process. It is a large, vertical tube that connects the pouring basin to the mold cavity. The main runner allows the molten ceramic to flow smoothly from the pouring basin into the mold cavity.
The main runner is typically made of a refractory material that can withstand high temperatures. The most common refractory materials used for main runners are fireclay, alumina, and magnesia.The main runner is an essential part of the ceramic casting process.
Refractory Main Runner for Bottom Pouring Set Suppliers in India
- Choose the material: The material of the main runner should be chosen to match the material of the mold cavity. This will help to prevent the main runner from reacting with the molten ceramic and causing defects. The most common materials for main runners are fireclay, alumina, and magnesia.
- Shape the main runner: The main runner can be shaped by hand, machine, or casting. Hand-shaping is the simplest method, but it is only suitable for small, simple main runners. Machine-shaping is more accurate and can be used to create larger or more complex main runners. Casting is the most versatile method and can be used to create main runners from a variety of materials.
- Drill the vent hole: A vent hole is drilled in the main runner to allow air to escape during the casting process. The vent hole should be located near the top of the main runner.
- Install the main runner: The main runner is installed in the mold cavity. The main runner should be positioned so that it is centered in the mold cavity and the vent hole is located at the top.
