Description
TECHNICAL FIELD
[0001] The utility model relates to metallurgical cooling water supply technical field, more specifically, a rotary water supply device. BACKGROUND
[0002] In metallurgical technology, the sudden local damage or easily damaged, easily eroded parts of the converter need to be repaired, and the refractory rotary gunning trolley is composed of a coaxial assembly of a conveying pipe, which transports refractory materials, oxygen and fuel. The refractory materials are sprayed from the conveying pipe and mixed with oxygen. At this time, the fuel is ignited to form a high-temperature flame. The refractory material becomes a viscous liquid when it encounters high temperature, and is sprayed onto the inner surface of the converter to form a repair. The existing gunning trolley sprays in the furnace. When the gunning trolley sprays in the furnace, the refractory material in the conveying pipe begins to melt into a viscous liquid due to the high temperature in the furnace, resulting in a utilization rate of only 20% to 50% of the refractory material sprayed in the furnace. Therefore, under the action of high temperature in the furnace, the refractory material will fall off from the furnace wall, not only increasing the cost of the spraying operation, but also reducing the quality of the spraying operation. Under normal circumstances, a circulating water pipe is arranged on the axis of the discharging pipe of the gunning trolley, and circulating water is circulated in the conveying pipe to reduce the overheating of the conveying pipe caused by the high temperature in the furnace, thereby improving the quality of the refractory material during the spraying operation of the gunning trolley.
