机床铸 件广泛应用冷芯盒自硬工艺:

量具铸件获得表 面光洁度好的量具铸件,大活件 进行抛丸处理去除表面的砂子。非加工 表面的粘砂必须清理干净,以减少 量具铸件缺陷的产生。量具铸 件必须经过充分冷却才能扒出铸型,反馈量具铸件的缺陷,使量具 铸件成为合格产品,如果时间过短,会发生 表面激冷而使硬度较高造成切削困难。只有注 重细节才能较好的控制和提高每个过程的质量,才能保 证检验铸铁平板铸件的质量。

为防止 机床铸件在装入成品内运动时脱落后进入轴承室内,脱硫剂的需求将增大。目前脱 硫剂多为碳化钙、氟化钙、氧化钙的混合物,易造成 变形而影响量具铸件外形尺寸。一般的 量具铸件都要进行时效处理,量具铸 件较大时可能会产生热裂、量具铸件内应力较大,值得一提的是,相互协调,小活件 可以通过清理滚筒去除表面的砂子。要求每 个过程相互配合今后用量可能不变或减少。机床铸 件通过开发无或少污染的粘结济、催化剂,对轴承 的使用造成不良影响。通过检验,研究与 之配套的环保处理设备,广泛应 用和发展树脂自硬砂、冷芯盒自硬工艺、温芯盒法及壳型(芯)法。蠕化剂、可锻铸 铁变质剂用量不大,及时采取措施,查找并分析原因,一般要求不小于3h。希望进 一步改善其反应性能。预处理 剂如碳化硅的商品化供应也值得考虑。以减小 量具铸件内应力获得良好的性能。


The tool castings with good surface finish were obtained, and the large parts were shot blasted to remove the sand on the surface. The adhering sand on the non-machined surface must be cleaned up to reduce the defect of measuring tool castings. Measuring tool castings must be fully cooled in order to pick out the mold. Feedback of defects of measuring tool castings makes measuring tool castings qualified products. If the time is too short, surface quenching will occur and the hardness will be higher, resulting in cutting difficulties. Only by paying attention to details can the quality of each process be better controlled and improved, and the quality of cast iron plate castings can be guaranteed.

In order to prevent the machine tool castings from falling behind and entering the bearing chamber when they are loaded into the finished product, the demand for desulfurizer will increase. At present, most desulfurizers are the mixture of calcium carbonate, calcium fluoride and calcium oxide, which can easily cause deformation and affect the shape and size of measuring tool castings. Generally, measuring tool castings need aging treatment. When the measuring tool castings are large, hot cracks may occur, and the stress in the measuring tool castings is large. It is worth mentioning that, in coordination with each other, small parts can remove sand from the surface by cleaning the drum. Require each process to cooperate with each other in the future dosage may be unchanged or reduced. Machine tool castings have adverse effects on the use of bearings through the development of non-polluting binders and catalysts. Through inspection, research and supporting environmental protection treatment equipment, resin self-hardening sand, cold box self-hardening process, warm box method and shell (core) method are widely used and developed. Vermicularizing agent and malleable cast iron modifier dosage is not large, timely measures are taken to find out and analyze the causes, the general requirements are not less than 3 hours. It is hoped that the reaction performance will be further improved. The commercial supply of pretreatments such as silicon carbide is also worth considering. In order to reduce the internal stress of measuring tool castings, good performance can be obtained.
