Good source of Tianjin Steel Tube Co., Ltd. specializes in producing coal mines with spiral spiral pipe pumping gas coal mine ventilation thin-walled spiral pipe spiral coal mine gas drainage pipe with spiral steel pipe, spiral steel pipe to buy high-quality coal on to a good source of Tianjin Steel Pipe Co., spiral pipe production process tundish steel flow runaway two cases: The first is the time to open burning out of control, out of control is mainly reflected in the tundish stopper control. When we put tundish stopper switch is turned off when the trial will find stopper steel stream can not be shut down, largely because of the low temperature of molten steel in the outlet and plug contact cooling of the steel skull Cypriots will live mine head spiral steel suppliers, so plugs can not shut down caused. When this case we need to open the stopper and let the steel flow punch of skull, this time plugs will automatically shut down. However, not all such cases mine spiral pipe model, because in the open burning when, within the mold volume is not large, especially when there is less in cross-sectional size, very easy to form overflow steel. So then, for some outside-mounted intrusion outlet groove insulation board is recommended to do a simple lightweight tank mine drainage spiral pipe manufacturers, specifically in Figure 1-20. After using the first open burning nozzle mounted intrusive way If you encounter this situation, when, in fact, only a few seconds of steel stream flow tens of time, it will melt skull, the stopper can normally closed, casting it can be normal, the other occasionally arise because the stopper is not installed due to closure could not, at this time we can do is to block off the flow of steel.
