Embodiment Construction
[0021] The structure and casting process of the copper water jacket of the present invention will be described in detail below through specific examples.
[0022] (1) Preparation of sand core cooling water pipe: Use clay core sand to prepare a "U" or "W" cooling water channel, and paint high temperature resistant casting paint on the outside of the cooling water channel.
[0023] (2) Preparation of deoxidized copper alloy water: firstly adopt the traditional "wood insertion reduction method" to deoxidize molten copper water, then add phosphorus, magnesium, arsenic, and yttrium in sequence to obtain molten copper alloy water; the copper alloy The mass percent content of each doping component in water is:
[0024] Phosphor bronze: 0.15-0.25%, magnesium: 0.001-0.002%, arsenic: 0.001-0.002%, yttrium: 0.015-0.020%.
[0025] In order to further improve the quality of copper alloy water, when smelting copper water, an inert gas is introduced into the refining furnace to remove oxide...
