对于水平分型有箱造型线，一些工程师认为不能采用底注式浇注机，必须采用大型茶壶包浇注机。例如国内某著名柴油机厂，生产发动机机体和和缸盖这些大批大量生产的单一灰铁铸件，他们花费近千万引进大型茶壶包浇注机进行浇注。但是实际上在国际上其他国家，这是标准的最适合采用气压保温浇注炉的运用场合。众所周知这种大型造型线，往往由许多主机和辅机组成，并且往往有繁重的下芯任务，常常因为种种原因停产。采用非加热浇注机，即使我们暂时我们不考虑浇注机的可靠性的影响，仅仅浇注机内铁水的温度损失就非常大，一旦造型线由于种种原因短时间停产，常常导致浇注机由于包内铁水温度过低而无法浇注，必须将铁水送回电炉升温，这样不但影响浇注机和造型线生产率，还影响电炉的正常生产。而且一旦造型线回复生产，浇注机有可能还需要烫包、预热后才能使用，极大地影响生产率。

For horizontal parting molding, some engineers believe that the bottom pouring machine can not be used. Large tea pot ladle casting machines must be used. For example, a famous diesel engine factory in China produces large quantities of single gray iron castings produced in large quantities by the engine block and cylinder head, and they spend nearly 10 million of the big teapots on the casting machine. But in fact, in other countries in the world, this is the most suitable standard for the application of air pressure heat preservation pouring furnace. As we all know, this large molding line is often composed of many mainframes and auxiliaries, and often has heavy core tasks, often for various reasons. Using the non heating casting machine, even if we do not consider the effect of the reliability of the casting machine for the time being, the temperature loss of the molten iron in the only casting machine is very large. Once the molding line is stopped for a variety of reasons for a short time, it often causes the pouring machine to be poured back to the electric furnace because of the low temperature of the molten iron in the ladle. This will not only affect the productivity of the casting machine and molding line, but also affect the normal production of the electric furnace. And once the molding line is back to production, the casting machine may need to be blanching and preheated before it can be used, which greatly affects productivity.
