我厂68年进行流态砂试验并投产,到目前为止,已经生产过滚齿机、插齿机、珩齿机,剃齿机、车床、磨床等各种中型机床20种左右,这些产品的中大件内外型全部用流态砂生产。生产了上万个铸件,总重量达数千吨。最小件100公斤左右。最大件3吨左右。质量基本稳定,铸件内外废总和一般不超过5%。流态砂造型成了我厂生产铸件的主要手段。目前流态砂生产工人约占车间造型工人的25%,但流态砂铸件产量却占铸件总产量的60%左右。我厂几年来的试验和生产实践证明流态砂造型法,是一项符合多、快、好、省的原则的新工艺。
I plant 68 years of fluidized sand test and put into operation, so far, has produced hobbing machine, gear shaper, honing machine, gear shaving machine, lathe, grinder and other medium-sized machine tools 20 or so, these products in the large Pieces inside and outside all with flow sand production. Production of tens of thousands of castings, the total weight of thousands of tons. The smallest piece of about 100 kg. The largest piece of about 3 tons. The quality is basically stable, the total amount of waste inside and outside the casting is generally not more than 5%. Flow sand molding has become my factory production of the main means of casting. At present, fluid sand production workers account for about 25% of the workshop styling workers, but fluid sand casting production accounts for about 60% of the total output of castings. Tests and production practices in our plant over the past few years have proved that the fluid sand molding method is a new process that meets the principle of multiple, rapid, good and provincial.
