Guniting Refractory Maintenance and Guniting Refractories
Jun 02 2019 · Only fine refractory materials are used in dry guniting process since higher particle size of the guniting material tend to rebound from the application surface. The guniting refractory material is required to generally have high effective cohesiveness to reduce rebound and produce a certain refractory build-up of the damaged surface.

Lost-foam castingWikipedia
Lost-foam casting (LFC) is a type of evaporative-pattern casting process that is similar to investment casting except foam is used for the pattern instead of wax.This process takes advantage of the low boiling point of polymer foams to simplify the investment casting process by removing the need to melt the wax out of the mold.
