FM法铸造能提高金属实收率,使铸件组织比较致密,适用于铸造实体、薄壁铸件。 FM铸造是一种调节压差的铸造方法,用来浇注难熔金属(铁、钢、高温合金),它具有许多优点: 自动浇注,有利于车间自动化,容易平稳、迅速充满铸型。它可在较低温度下浇注金属,使型芯、耐火材料受的热作用、机械作用较小。可浇注出薄壁、复杂的铸件(壁厚可达2.5毫米)。 FM法铸造用液流定向凝固、动力保温冒原理获得的铸件合格率高,容易清理。
FM casting method can improve the real yield of metal, so that the relatively dense castings, suitable for casting entities, thin-walled castings. FM casting is a differential pressure casting method used to cast refractory metals (iron, steel, superalloy). It has many advantages: automatic pouring, which helps the shop to automate, smooth, and quickly fill the mold. It can pour metal at a lower temperature, so that the core, refractory material by the thermal effects of mechanical action smaller. Castable thin-walled, complex castings (wall thickness up to 2.5 mm). FM casting fluid directional solidification, thermal insulation to obtain the principle of casting high pass rate, easy to clean.
