Examples
Embodiment 1
[0022] Example 1, using pure aluminum as a raw material to prepare a semi-continuous production process for closed-cell aluminum foam.
[0023] In this embodiment, calcium metal is used as a tackifier, and titanium hydride is used as a foaming agent.
[0024] The specific implementation of this embodiment includes the following steps:
[0025] Step 1, assemble more than 000 composite molds. First place the asbestos rope soaked in high-temperature glue in the groove 023 on the bottom plate of the filling mold 020, then hoist the transition crucible 010 so that the bottom of the transition crucible 010 is embedded in the groove 023, and then, use high-temperature glue and asbestos powder The prepared paste fills the joint between the transition crucible 010 and the filling mold 020 to obtain a composite mold 000;
[0026] In the second step, preheat the composite mold 000, vacuum ladle 110, tundish 120 and foaming furnace 208. Their preheating temperatures are 680°C, 900°C, 900°...
Embodiment 2
[0036] Example 2, using ZL102 as a raw material to prepare a semi-continuous production process of closed-cell aluminum foam.
[0037] In this embodiment, calcium metal is used as a tackifier, and titanium hydride is used as a foaming agent.
[0038] The specific implementation of this embodiment is basically the same as that of Embodiment 1, the difference is the following process parameters.
[0039] ①. The preheating temperatures of composite mold 000, vacuum ladle 110, tundish 120 and foaming furnace 208 are 650°C, 900°C, 900°C, and 620°C respectively, and the preheating temperature is allowed to have a deviation of ±10°C.
[0040] ②. The melting temperature of ZL102 aluminum ingot is 780 in the melting furnace 100, and the melt is kept at this temperature. The melting and holding temperature are allowed to have a deviation of ±10°C.
[0041] 3., the tackifier calcium add-on of the present embodiment is 3%, and foaming agent add-on is 1.5%, and the time of stirring after ...
Embodiment 3
[0043] Example 3, using fly ash as a tackifier to prepare a semi-continuous production process of closed-cell aluminum foam.
[0044] In this embodiment, fly ash is used as a tackifier, zirconium hydride is used as a foaming agent, and pure aluminum is used as a raw material for production.
[0045] The specific implementation of this embodiment is basically the same as that of Embodiment 1, and the main difference with Embodiment 1 is as follows:
[0046] ①. The preheating temperature of the vacuum ladle 110 and the tundish 120 is the same as 780°C, and the preheating temperature is allowed to have a deviation of ±10°C.
[0047] ②. The melting temperature of pure aluminum ingots in the melting furnace 100 is 800, and the melt is kept warm at this temperature. The melting and holding temperatures are allowed to have a deviation of ±10°C.
[0048] 3. The amount of the tackifier fly ash added in the present embodiment is 5%; when the present embodiment proceeds to the "6th step...
