對于水平分型有箱造型線,一些工程師認為不能采用底注式澆注機,必須采用大型茶壺包澆注機。例如國內某著名柴油機廠,生產(chǎn)發(fā)動機機體和和缸蓋這些大批大量生產(chǎn)的單一灰鐵鑄件,他們花費近千萬引進大型茶壺包澆注機進行澆注。但是實際上在國際上其他國家,這是標準的最適合采用氣壓保溫澆注爐的運用場合。眾所周知這種大型造型線,往往由許多主機和輔機組成,并且往往有繁重的下芯任務,常常因為種種原因停產(chǎn)。采用非加熱澆注機,即使我們暫
型線 流水槽模具 景觀石 檢查井鋼模具 保定通風管道 隔離墩模具 保定保潔公司時我們不考慮澆注機的可靠性的影響,僅僅澆注機內鐵水的溫度損失就非常大,一旦造型線由于種種原因短時間停產(chǎn),常常導致澆注機由于包內鐵水溫度過低而無法澆注,必須將鐵水送回電爐升溫,這樣不但影響澆注機和造型線生產(chǎn)率,還影響電爐的正常生產(chǎn)。而且一旦造型線回復生產(chǎn),澆注機有可能還需要燙包、預熱后才能使用,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.
