Embodiment 1
[0014] Embodiment 1: A method for preparing a core layer composition of a cored wire.
[0015] Take 100 parts of lime powder (with a particle size of less than 0.15mm) and 48 parts of aluminum particles (with a particle size of less than 2mm), and add fluorite powder whose weight does not exceed 5% of the total weight, mix the above materials evenly and make them into a block, then put them into the smelting furnace Among them, the smelting furnace can adopt a resistance heating vacuum smelting furnace, and then send electricity to raise the temperature and pump a vacuum to keep the vacuum in the smelting furnace at any vacuum value between 10Pa and 50Pa. When the temperature in the furnace reaches 500°C- Stop vacuuming at 600°C, then add inert gas into the smelting furnace, and continue to heat up to smelt the materials in the furnace. The smelting temperature is not lower than 1100°C, generally not higher than 1300°C. When the smelting temperature is 1300°C, The smelting tim...
Embodiment 2
[0019] Example 2: The composition of the core layer of the cored wire is prepared by a preparation method.
[0020] Take 40Kg of elemental calcium, 10Kg of calcium-aluminum alloy, and 50Kg of calcium-aluminate, and mix these three materials thoroughly to make a core layer composition.
Embodiment 3
[0021] Example 3: The composition of the core layer of the cored wire was prepared by a preparation method.
[0022] Take 10Kg of elemental calcium, 50Kg of calcium-aluminum alloy, and 40Kg of calcium-aluminate. These three materials are fully mixed to form a core layer composition.
