Advantages of Gunning Refractory
Reduced Downtime
Gunning allows fast, on-site repairs without dismantling equipment, saving significant time and production costs.
Cost-Effectiveness
Eliminates the need for formwork, extensive labor, and long curing times, reducing overall repair expenses.
Versatility
Can be applied to complex shapes, vertical walls, and overhead areas without sagging.
Extended Furnace Life
Timely patching with gunning mixes helps extend the lifespan of expensive refractory linings.
Improved Safety
Quick application minimizes workers’ exposure to high-temperature environments.
Material Efficiency
Advanced gunning techniques minimize rebound loss (waste material that falls off during spraying), making the process more economical.

Acid Resistant Gunning Mixes
Acid-resistant gunning mixes are made of acid-resistant aggregate and powder, adding water glass or Portland cement and admixtures. It is mainly used for the protective layer of hot blast stove dome steel plates and various chimneys. The acid-resistant gunning refractory can also be poured, and spraying or pouring can be selected according to the construction conditions on-site.
Ceramic Gunning Mixes
Ceramic gunning mixes are the most widely used gunning refractory. The lining can be built as a whole, and it can also be repaired by gunning. During the construction, the bulk material is conveyed by air, and sprayed to the part that needs to be used or repaired by the spray gun, and can also be smeared. At present, the use of lime kiln lining has become a trend in the market.
Aluminum Silicate Gunning Refractory Mix
The aluminum silicate gunning refractory mix’s main components are Al2O3 and SiO2. Aluminum silicate gunning mix includes heavy, semi-lightweight, and lightweight types. Heavy gunning mix’s bulk density is no less than 1.8g/cm3, the bulk density of semi-lightweight gunning mix is between 1.3~1.8g/cm3, and the bulk density of lightweight gunning mix is less than 1.3g/cm3.
Installation Of Gunning Refractory
Shotcrete
Shotcrete is typically a low-cement, low-moisture refractory that is fully tempered and mixed with water and special binding additives, and then projected at high velocity onto a surface. With shotcrete, the concrete is already mixed in a cement truck before you shoot it out of a hose.
Gunite
Gunite is a dry monolithic refractory designed for use with dry gunning equipment. It uses compressed air to send the dry material to the nozzle, where it mixes with water. Then it sprays out at super high velocity, which compacts the material on placement.
Ramming
Ramming plastics and castles is perfect for allowing workers to hand-ram them into place. Lining-support fittings are attached to the shell (metal anchors or ceramics tile anchors for the wall). The material is quite literally rammed into place using a pneumatic hand hammer. Forms may or may not be used, depending on the situation.
Casting
Casting refers to pouring wet castables into forms. Castables can be poured into forms to achieve whatever shape is desired or even molded by hand. Once the cement in the mix is hydrated and completely secure, the forms can be removed.
Steel Industry
Repairing basic oxygen furnaces (BOFs) and electric arc furnaces.
Patching ladle sidewalls and slag lines.
Restoring tundish linings between heats.
Cement and Lime Industry
Spot repairs in rotary kilns, preheater cyclones, and clinker coolers.
Extending refractory life during peak production periods.
Glass Industry
Maintenance of regenerators, forehearths, and crown linings.
Non-Ferrous Metallurgy
Copper, nickel, and aluminum smelters use gunning mixes to minimize downtime.
Petrochemical and Power Plants
Used in incinerators, gasifiers, boilers, and reformer furnaces for efficient patching.
