Ensure that 2 temperature change of spray gun brick is small, the spray gun Copper Water Jacket 3 casts Copper Water Jacket using drilling, pipe laying, spray gun Copper Water Jacket 3 into
Outlet pipe distribution and heart septum 100-150mm in spray gun 1, and accessed with system circulating water, and returning in each spray gun Copper Water Jacket 3
Water outlet pipe is arranged return water temperature and detects, and guarantees real-time monitoring water temperature, and spray gun 1 penetrates on the outside of spray gun ramming layer 4, the spray gun
Ramming layer 4 is tamped using the pourings such as magnesia, high chromium matter, indefinite form castable refractory, thickness control 80-150mm, then uses steel deck-plate
Sealing after being sealed and fixing, can effectively prevent gas leakage, seep slag, seep lead, and is horizontal through spray gun ramming layer 4, spray gun copper
Water jacket 3, spray gun brick 2, finally stretch out on the outside of spray gun brick 2, and spray gun Copper Water Jacket circulating water pipe 7 is at the top of 3 outer wall of spray gun Copper Water Jacket
Level penetrates into spray gun Copper Water Jacket 3 and along 3 bottom bending forming of spray gun Copper Water Jacket, finally along 4 outer wall bottom of spray gun ramming layer
It is pierced by, water flow is constantly circulated through in spray gun Copper Water Jacket circulating water pipe 7, and spray gun Copper Water Jacket 3 is taken away in flow process
And the heat that spray gun Copper Water Jacket 3 generates, further reach cooling effect, the gun slot and high temperature molten bath contact portion of spray gun 1
Using magnesium chromium matter or other refractory materials, spray gun brick 2 selects magnesium chromium matter, high alumina, aluminium chromium, high chromium matter refractory brick to be made, spray gun brick
2 gun hole is used with the porous of 1 diametric fit of spray gun to reduce brickwork joint and build conveniently, and system for detecting temperature includes spray gun
Brick temperature measuring point 5 and spray gun Copper Water Jacket temperature measuring point 6, spray gun Copper Water Jacket 3 is close on the two sides of spray gun brick 2 and spray gun ramming layer 4 points
The spray gun brick temperature measuring point 5 and spray gun Copper Water Jacket temperature measuring point 6 of different height, spray gun brick temperature measuring point 5 and spray gun copper water She You be located at
Set temperature measuring point 6 selects corresponding temperature sensor, is mounted on spray gun Copper Water Jacket 3 close to the two of spray gun brick 2 and spray gun ramming layer 4
On side, temperature sensor is connected with reduction furnace DCS system, passes through setting spray gun brick temperature measuring point 5 and spray gun Copper Water Jacket thermometric
Point 6 can monitor temperature in real time to judge that 2 scaling loss situation of spray gun brick and Copper Water Jacket use safe, the system for detecting temperature utilization
Spray gun brick 2,3 temperature of spray gun Copper Water Jacket are transmitted to the monitoring of reduction furnace DCS system by temperature sensor, wherein spray gun brick temperature measuring point 5
It is installed on apart from the upper and lower 100mm in 1 center of spray gun, detects 0-1500 DEG C of temperature, spray gun Copper Water Jacket temperature measuring point 6 is installed on distance spray
1 center 80mm of rifle detects 0-1000 DEG C of temperature, and temperature signal is transmitted to DCS system, when 2 surface temperature of spray gun brick is more than 850 DEG C
When refractory material can scaling loss it is serious, the alarm temperature of spray gun brick temperature measuring point 5 is set as 750 DEG C in the system for detecting temperature, when
Spray gun brick temperature measuring point 5 reaches 750 DEG C of sending alarms, produces organization of production inspection.Spray gun Copper Water Jacket 3 detects 0-1000 DEG C of temperature,
