The present invention is a mechanism that identifies the cooling duct and the water jacket to protect the duct and iron shell in the blast furnace body when the melt damage due to the impact of the molten iron and the increase of heat load.

Conventional identification methods have been identified by vibrating the flame and bubble-generating drain pipes of the tuyere and cooling half drains, foreign matter adhesion at the tip of the tuyere, leaking stage and water leakage, and ignition of the drainage and deterioration of water pressure. Due to the low accuracy of identification, it was difficult to detect misjudges and damages early, resulting in problems such as low furnace temperature and furnace yellowing caused by submerged cooling water in the furnace.

The present invention is an identification method that is effective for accurate identification and early detection of damage. The principle is that the gas inside the furnace flows out into the drain through the melting zone and is mixed with the cooling water by the pressure inside the furnace in the case of the blowhole and the cooling panel. When detecting and measuring with a gas meter and the degree of loss based on the measured value will be described in detail based on the accompanying drawings.

Open the air discharge valve (4) slightly and reduce the water in the drain and cooling bin drain to about 1/2 to increase the difference between the pressure in the furnace and the outlet and the pressure in the cooling cabinet. Open the upper valve (2) and flow it into this container. At this time, the injection through the injection nozzle (3) to increase the effect on the separation of water and gas. The sprayed water is slowly filled in the container by the resistance of the resistance partition (7). At this time, if the water is filled about 2/3 through the oil level gauge (5), the drain valve (6) is adjusted to keep the water level constant.The air discharge valve (4) is completely opened and the gas detector is used to GAS) is designed to measure the amount of the hand loss based on the measured value, and the notation A in the drawing indicates the vent hole of air.

Claims (1)

A spray nozzle (3) capable of injecting water in the vessel, a resistance partition (7) for lowering the flow rate of water, a built-in oil level gauge (5) for monitoring the water level, and a drain valve for adjusting the water level ( 6) Identification gas detector installed.
