Conclusions

The life of concrete linings in y-shaped pouring spouts is threefold that of chamotte linings. The main wear of the concrete lining is accounted for by the mechanical removal of the 8 to 10 mm thick slag — concrete contact layer during cleaning operations.

The applicating of coatings of different composition substantially affects the structure of the concrete — slag contact layer.

There was no difference in quality between metal poured through chamotte lined spouts and concrete — lined spouts.

The use of concrete lining for y-shaped pouring spouts is warranted for technical and economic reasons. Further increase in the service life of this type of lining requires more testing and extensive adaption to industrial furnaces.
