The following terminologies which have been given for different type of Monolithic Refractory products are based on and therefore, can be related to their lining process or installation methods. Read our previous article
Castables
These are dry mix hydraulic compositions of graded refractory aggregates with a suitable bonding material, Fillers & (/or) special Additives. On addition of the prescribed quantity of water to these compositions, a wet concrete-like mass is produced which forms useful castables. Ceramic bond is developed when the same is fired at a certain high temperature.
Type of Castables -
- Conventional Castable.
- Low Cement Castables (LCC).
- Ultra Low Cement Castable (ULCC).
- No Cement Castable (NCC).
- Light Weight Castables.
- Self Flow Castables (SFC).
- Insulating Castable.
Coating Mass
These are the Refractory materials especially made for coating on the working surface of the lining having a thin thickness.
Fettling Mass
It is a material which is deposited on the worn out areas of banks and bottom of Electric Arc Furnace (EAF) in hot condition. These are normally applied by shoveling and by using a Fettling Machine.
Gunning Compound or Gunning Mass
Gunning Masses are also unshaped refractory materials (Products) made after blending graded refractory grains with suitable bonding agents and are installed with a Gunning Machine.
Type of Gunning Compounds -
- Dry Gunning
- Shortcreting
- Flame Gunning
Injection Mass
These are the refractory materials that can be injected into a furnace in the slurry state.Mortar
Powdered or finely ground refractory preparation which becomes plastic and trowel able when tempered with water and is suitable for laying and bonding refractory bricks.
Patching Mass
These are powdered refractory materials mixed with water and/or added with a binder, and with adequate plasticity that can be patched in a place.
Plastic Refractories / Mass / Plastics
Refractory materials tempered with water and/or added with a binder, which has adequate plasticity to be rammed into a place.
Ramming Mass
Ramming Masses are the ready-mix of refractory materials usually tempered with water, that can not be extruded but that has suitable properties to permit ramming into a place to form a monolithic structure.
Type of Ramming Masses -
- Dry Ramming Mass
- Wet Ramming Mass
Spraying Mass
These are refractory mix consisting of fines and additives which are installed with a Spraying Machine (can also be applied with a Gunning Machine).
