Conclusions
It was established that plastically formed bottom pouring tubes with an open porosity of 15–18% have a low heat resistance. A 40–60°C reduction in firing temperature makes it possible to eliminate production of low-quality bottom pouring parts. It is also possible to eliminate the bottom portion of the charge of normal brick and make the charge completely of bottom pouring parts.
For the purpose of realization of the positive qualities and broadening the production of bottom pouring tubes with an open porosity of more than 18% it would be desirable to eliminate from GOST 11586-69 the requirement for additional shrinkage at 1350°C.
