Refractory gunning machine uses high-pressure spraying of refractory materials to quickly repair the refractory layer of high-temperature components such as kiln linings, preheaters, and coolers. Their core advantages lie in efficient repair, reduced downtime, and lower labor intensity. They are particularly suitable for partial or overall refractory layer maintenance of equipment such as rotary kilns, decomposition furnaces, and grate coolers in cement plants.
Refractory gunning machines for repairing EAF use compressed air or a mechanical pump to mix refractory materials (such as magnesia and alumina-magnesia gunning materials) with water or a binder, then spray them at high speed onto the worn areas of the electric arc furnace lining, forming a dense repair layer. For electric arc furnace (EAF) gunning repairs, we recommend using refractory gunning machines with high-pressure output, wear-resistant nozzles, automated control, and explosion-proof design. Their core function is to repair the furnace lining by spraying refractory materials at high pressure, and key parameters must be compatible with the high-temperature, high-wear environment of the EAF.
