description The invention provides a boiling device for treating blast furnace hearth freezing, which comprises a burning gun, two metal hoses and an operation control frame, the burning gun comprises an inner oxygen pipe and an outer compressed air pipe, and the operation control frame comprises an oxygen pipe, a compressed air pipe, five valves and four pressure gauges; the invention provides a boiling method for treating blast furnace hearth freezing. According to the device, oxygen is wrapped by compressed air, through on-off cooperation, pressure cooperation and flow cooperation of the oxygen and the compressed air, oxygen combustion melting and high-pressure compressed air knife cutting are carried out at the same time, and liquid melt in a melting hole is rapidly discharged outwards through the compressed air and is not condensed in the hole any more; therefore, the burning-through speed of the frozen hearth is remarkably increased, the burning-through effect is better and safer, secondary damping down and tapping
