对覆膜砂的认识与了解

发布时间:2020-01-11
(1)覆膜砂的特点:具有适宜的强度性能;流动性好,制出的砂型、砂芯轮廓清晰,组织致密,能够制造出复杂的砂芯;砂型(芯)表面质量好,表面粗糙度可达Ra=6.3~12.5μm,尺寸精度可达CT7~CT9级;溃散性好,铸件容易清理。(1) characteristics of coated sand: good strength performance, good fluidity, clear sand core, dense sand core, dense sand core and complex sand core; sand mold (core) surface quality is good, surface roughness can reach Ra=6.3 ~ 12.5 mu, size accuracy can reach CT7 to CT9 grade, collapsibility is good, casting easy to clean up.(2)适用范围:覆膜砂既可制作铸型又可制作砂芯,覆膜砂的型或芯既可互相配合使用又可与其它砂型(芯)配合使用;不仅可以用于金属型重力铸造或低压铸造,也可以用于铁型覆砂铸造,还可以用于热法离心铸造;不仅可以用于铸铁、非铁合金铸件的生产,还可以用于铸钢件的生产。(2) scope of application: coated sand can be used not only to make casting mould but also to make sand core. The type or core of the coated sand can be used in combination with other sand type (core). It can be used not only for metal type gravity casting or low pressure casting, but also in iron type sand casting and centrifugal casting. It can be used not only for cast iron and non iron alloy castings but also for cast iron and non iron alloy castings. It can be used in the production of steel castings.
