Refractory gunite machine is widely used in spraying refractory materials for lining kilns, boilers, furnaces, steel plant, cement factory, degasser lining etc. And it also could be used for heat and cold repair of vacuum degasser linings.
We sell various output refractory gunning machine apply in steel plant, such as: 3m3/h, 5m3/h, 7m3/h, 9m3/h. And electric engine and air motor can be customized according to customer requirements. For example：

The rated output of LZ-3ER steel plant refractory gunite machine is 3m3/h, its electric engine power is 4Kw, its operating air pressure is range from 2-4bar, its local voltage are respectively 3phase, 380V, 50Hz, and its max horizontal conveying distance is 100m.
The rated output of LZ-3AR steel plant refractory gunite machine is 1-3m3/h, its air motor power is 4Kw, its operating air pressure is range from 2-4bar.
Precautions for the use and operation of refractory gunite machine apply in steel plant:
1. Preparation before starting
A. Check whether the contacts of each circuit of the electric control system are firm and whether there is any leakage.
B. Observe the oil mark and check whether the lubricating oil in the reducer is sufficient.
C. Check whether the connection and fastening of each part of the machine are correct and reliable.
D. Run the steel plant refractory gunite machine for a short time in order to grasp the rotation situation (pay attention to whether the direction of rotation is consistent with the direction of the arrow, look counterclockwise from above, but do not idling for a long time).
2. How to start spraying operation
A. After the preparation work is completed, materials can be added to the steel plant refractory gunite machine. At this time, the machine operator should first open the main valve to adjust the working pressure.
B. The operator opens the nozzle water valve to pre-wet the spray surface.
C. The operator starts the steel plant refractory gunite machine to start the refractory spraying operation. According to the water-cement ratio of the material and the conveying distance, adjust the wind pressure to the cyclone until the spraying operator thinks that the jet velocity is appropriate.
3. Stop spraying operation
A. Shut down and blow out the remaining materials in the conveying pipeline.
B. When the pipeline is clean, no material is sprayed from the nozzle.
C. Finally, close the main air pipe valve.
Materials can be stored in the hopper when the spraying operation is temporarily interrupted;
After a long pause or spraying operation is over, you must first stop feeding and let the steel plant refractory gunite machine continue to run until the residual material in the hopper and rotor cavity is exhausted, then the air valve can be closed.
4. Precautions
Strictly prevent longer and larger objects, such as steel bars, iron plates, etc., from entering the rotor material cavity during use, which may cause a larger crash.
