Abstract
An air blast system for melting furnaces includes: a supply unit supplying hot air into a melting furnace; a bustle pipe connected to the supply unit; a tuyere stock connecting the bustle pipe to the melting furnace to supply hot air from the bustle pipe to the melting furnace in a distributed manner; and a temperature management module determining whether the tuyere stock is damaged by comparing a temperature of the tuyere stock with a preset reference temperature.
Claims9
A tuyere stock comprising:
- a refractory layer having an inner surface defining a flow channel contacting hot air;
- a heat conduction layer disposed on an outer surface of the refractory layer and heated by heat transferred from the refractory layer;
- an outer heat insulation layer disposed on an outer surface of the heat conduction layer and blocking transfer of heat from the heat conduction layer to an outside environment or transfer of external heat to the heat conduction layer;
- a temperature sensor detecting a temperature of the heat conduction layer;
- and
- an inner heat insulation layer disposed between the refractory layer and the heat conduction layer,
- wherein the inner heat insulation layer deforms and undergoes a sharp increase in thermal conductivity when a temperature of an inner surface of the inner heat insulation layer contacting the refractory layer exceeds a preset temperature.
