對(duì)于水平分型有箱造型線，一些工程師認(rèn)為不能采用底注式澆注機(jī)，必須采用大型茶壺包澆注機(jī)。例如國(guó)內(nèi)某著名柴油機(jī)廠，生產(chǎn)發(fā)動(dòng)機(jī)機(jī)體和和缸蓋這些大批大量生產(chǎn)的單一灰鐵鑄件，他們花費(fèi)近千萬(wàn)引進(jìn)大型茶壺包澆注機(jī)進(jìn)行澆注。但是實(shí)際上在國(guó)際上其他國(guó)家，這是標(biāo)準(zhǔn)的最適合采用氣壓保溫澆注爐的運(yùn)用場(chǎng)合。眾所周知這種大型造型線，往往由許多主機(jī)和輔機(jī)組成，并且往往有繁重的下芯任務(wù)，常常因?yàn)榉N種原因停產(chǎn)。采用非加熱澆注機(jī)，即使我們暫時(shí)我們不考慮澆注機(jī)的可靠性的影響，僅僅澆注機(jī)內(nèi)鐵水的溫度損失就非常大，一旦造型線由于種種原因短時(shí)間停產(chǎn)，常常導(dǎo)致澆注機(jī)由于包內(nèi)鐵水溫度過(guò)低而無(wú)法澆注，必須將鐵水送回電爐升溫，這樣不但影響澆注機(jī)和造型線生產(chǎn)率，還影響電爐的正常生產(chǎn)。而且一旦造型線回復(fù)生產(chǎn)，澆注機(jī)有可能還需要燙包、預(yù)熱后才能使用，極大地影響生產(chǎn)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.
