铸造工业从古代就被人们所采用,是用金属制造有用器具的最早的生产方法之一,并得到持续不断的发展。如果列举真正的基础工业,那么铸造工业一定接近于排列名单的首位。现在,尽管对塑料及其他合成品需要量越来越大,但对铸件的需要量仍将日趋增长。现代的铸造工厂,或者更确切地说,现代的铸造机械设备,已成为体现自动化而发展到了惊人程度的设备之一。购入原材料的分类、贮藏、机械发料及供料;使用计算机把配比最经济、最恰当的炉料加入熔化炉内;以最适合的比例把粘结剂和水分准确地加入混砂机中,并在给定的时间内混制型砂;用胶带输送机把混制好的型砂送给造型机,把所需要量的型砂置于造型机内以严格的、可以调节的压力造型;砂芯的制造、下芯和合箱等等也都全部自动化了。铸件的落砂、清理、检验、热处理、有时甚至连装箱等也都同样地实现了自动化。然而,这些现代铸造工厂合理化中所存在的问题是浇注工序。至今的浇注作业均是人工用浇包把高温金属液注入铸型,就像用铁皮桶把水注入汽车的散热器内一样。真正以全自动方式进行浇注作业的是这里所介绍的最新的自动浇注装置。该装置不仅是浇注金属液,而是把精度很高的浇注工作准确地、随时可以重复地、自动地进行。
The foundry industry has been adopted by people since ancient times and is one of the earliest methods of manufacturing useful utensils made of metal and has been continuously developed. If you list the real basic industries, then the foundry industry must be close to the top of the list. Now, despite the growing demand for plastics and other synthetics, the demand for castings will continue to grow. Modern foundry factories, or rather, modern foundry machinery, have become one of the devices that have taken the automation to an astonishing level. Buy the raw material classification, storage, mechanical hair and feeding; the use of computer to the ratio of the most economical and most appropriate charge into the melting furnace; the most appropriate proportion of the binder and water to accurately join the sand mixer, And in a given period of time mixed sand; with a belt conveyor to the mixed good sand sent to the molding machine, the required amount of sand placed in the molding machine with a rigorous, adjustable pressure modeling; sand core Made, under the core and co-boxes, etc. are all automated. Casting the sand, cleaning, inspection, heat treatment, and sometimes even packing, etc. are also realized the same automation. However, the problem with the rationalization of these modern foundries is the pouring process. Pouring operations so far have been artificially ladle with high temperature molten metal into the mold, like a metal bucket with water into the car’s radiator the same. The real automatic pouring operation is the latest automatic pouring device introduced here. The device is not only pouring liquid metal, but the high accuracy of the pouring work accurately at any time can be repeated automatically.
