Because materials are preheated in the tower, exhaust heat is emitted at a low temperature, contributing to energy savings. Further, the melting temperature is as close as pos- sible to the melting point, requiring less energy than higher temperature furnaces. At 1,200 x 2,220 x 2,650 mm), the compact furnace releases waste heat at 450C or less and emits low noise. Ceramic fiber can be used for the inner lining, adding to the furnace’s light weight and allowing heating and start-up within 60-90 minutes. Because of the quick start-up, burners can be turned off com- pletely on weekends or overnight. Nippon Crucible has paired the Mel-Keeper furnace with

its Zebrax graphite crucibles, which feature vertical convex and concave grooves that increase the surface area to receive more heat. With 30% increased surface area, the crucibles
节省能源。此外，熔炼温度尽可能接近熔点，使得Mel- Keeper炉比高温熔炼炉可以节省更多能源。 该紧凑型炉子的尺寸为1,200 x 2,220 x 2,650 mm , 废气排放温度小于450℃，而且噪音很小。由于采用陶 瓷纤维作为炉衬，大大减轻了炉子的重量，同时可以在 60-90分钟内快速加热和启动。正是因为这一点，在周 末或晚上，燃烧器可以停止工作。 Nippon Crucible公司为Mel-Keeper炉设计了配套 的Zebrax石墨坩埚。坩埚的垂直突起和凹沟的设计增 加了表面积，这样可以吸收更多的热量。经测试增加了
30%的表面积，节约能源比例达到了8-10%。■ 获取更多信息，请登录

Semi-Solid Diecasting Produces Solid Components 半固态压铸可生产高性能零件
For many potential diecasting applications, the
porosity level obtained with the traditional process isn’t sufficient to satisfy customer mechanical property re- quirements. Today, demanding leak tests and defect-free
对于许多压铸件来说，传统工艺流程下铸件的孔隙 率不能满足客户对于产品机械性能的需求。现今产品需 要具有无缺陷的加工表面并进行苛刻的浸渗测试。真空
