Exotherm powder for increased nutritional efficiency Order of Consumption For nutritional applications for aluminum and copper base parts to reduce heat losses to the environment. Target After casting, exothermic materials or heat-generating compounds for feeding are a good way to control the heat loss caused by exposure to radiation or open surface conjugation. Since nutrition should be the last part of the mold that is frozen, in order to obtain the nutritional design potential, it must either feed or feed larger and thicker than other parts of the casting, or drop the temperature to the sand and the environment. Controlled.
Blind feeding (pack) is used for weight and minimum nutritional sizes. The temperature is better protected, especially with regard to the short suffering of freewheeling or shell alloys such as: LM6 bronze aluminum and rice with high tensile strength.
