The ladle preheating system preheats the refractory of the ladle uniformly to 1,200 ℃ before the molten metal is poured in. Combustech supplies combustion system with the energy costs reduced more than 50% compared to conventional air-fuel systems and has more than 100 installation references.

Combustech’s R&D centre conducts all of its engineering activities including combustion technology (burner development, heating calculation, heat flow analysis), control technology (Level 1, Level2) and mechanical design (structural analysis). We supply self-produced furnaces including commissioning on a turnkey basis. Based on our long experience, Combustech implements diagnostic and improvement consulting services to our customers’ industrial facilities.                                         

Application Benefits
