Guniting Refractory Maintenance and Guniting IspatGuru
Jun 02 2019 · Guniting refractories are monolithic refractories which are installed by guniting process. Guniting refractories consist of graded refractory aggregate and a bonding compound and can contain plasticizing agent to increase their stickiness when pneumatically placed onto a furnace wall. Typically guniting refractories are supplied dry.
