Casting common filters are the following:

1, a glass fiber filter by: high temperature glass fiber cloth specially treated, filtered and poor, cheap.

2, straight hole: Filters better, cost-effective, widely used.

3, ceramic foam filters: the skeleton made of foam, coated with a ceramic slurry is baked, the best filtering effect, widely used. Different metals commonly used in the filtration of refractory aggregate.

4, a large valve casting with silica ceramic foam filters;

5, silica ceramic foam filter is the latest in a filter, a better performance than conventional high temperature ceramic foam filter size can be made bigger, filtered large steel, cast iron, lower heat storage coefficient, Unit head liquid metal cooling small.
