Thin-Wall Ladle Improves Aluminum Diecaster’s Efficiency 薄壁浇包提高了铝合金压铸的效率
As part of a plant-wide cost-savings initiative, Gen-
eral Aluminum Manufacturing’s Fremont, Ind., diecast- ing facility recently replaced its fiber laminate ladles with thin-wall auto-pour ladles from Pyrotek Inc., Spokane Valley, Wash., to cut down on its maintenance costs and achieve longer ladle service life. General Aluminum had been experiencing two to six
weeks of service with its fiber laminate ladles. The new auto-pour ladles, using reinforced fiberglass material (RFM) technology, consistently achieve six months of service life and more than 150,000 shots. General Alu- minum also has experienced reduced oxide-induced scrap and improved cast repeatability from ladle to ladle. RFM ladles have gained popularity in squeeze cast-
ing, sand casting and permanent mold aluminum casting operations as a result of their low maintenance requirements, longer service life, non-wetting and insulating properties. General Aluminum found that the non-wetting surface of Pyrotek’s ladles prevented skull build-up. Metal build-up
General Aluminum Manufacturing公司所属的位 于印第安纳州Fremont市的压铸厂最近在全公司范围开 展节能活动中采用位于华盛顿州Spokane Valley 市的 Pyrotek公司的薄壁自动浇包替代了耐火纤维浇包，以 便削减浇包维护成本，提高浇包使用寿命。 General Aluminum公司采用耐火纤维浇包使寿命可 达2~6周，而采用了新的自动浇包，其中应用了增强玻 璃纤维材料技术，稳定地将浇包寿命提高到了6个月， 超过了15万次。该公司还降低了由于氧化产生的废品， 提高了各浇包之间质量的可重复性。
增强玻璃纤维技术在铝合金挤压铸造、砂型铸造和金 属型铸造方面的反映很好，具有维护成本低、寿命长、 不浸润、保温等特点。 General Aluminum发现Pyrotek的浇包的表面不浸
