摘要： An at least two step heating process is used to strengthen the shell of an investment casting mold including a refractory metal core. The first stage may occur under otherwise oxidizing conditions at a low enough temperature to avoid substantial core oxidation. The second stage may occur under essentially non-oxidizing conditions at a higher temperature.
摘要翻译： 使用至少两步加热工艺来加强包括耐火金属芯的熔模铸造模具的壳体。 第一阶段可以在足够低的温度下在其它氧化条件下进行，以避免大量的核心氧化。 第二阶段可以在较高温度的基本非氧化条件下进行。

摘要： Pre-molding of wax or similar sacrificial material over one or more cores facilitates a subsequent molding over a core assembly. Individual cores or groups thereof may be pre-molded in a wax body. One or more such wax bodies may be assembled with other bodies and/or other cores to facilitate a main wax molding of such assembly.

摘要： A snowmobile having a multiple endless track propulsion system. The multiple track propulsion system includes a rear endless track operably supported to engage a ground surface, and a pair of steerable front endless tracks positioned forward of the rear endless track. The front endless tracks are oriented in a spaced-apart, parallel relationship to one another, and operable to engage the ground surface. A power supply is disposed in the snowmobile body and operably configured to power the rear endless track and the pair of front endless tracks to propel the snowmobile.

摘要： An investment casting pattern is formed by forming a metallic first core element including at least one recess. The first core element is engaged to at least a mating one of an element of the die and a second core element. The recess serves to retain the first core element relative to the mating one. The die is assembled and a sacrificial material is introduced to the die to at least partially embed the first core element. The recess may be pre-formed prior to cutting the first core element from a larger sheet of material.
