Embodiment 1
[0033] This embodiment provides a copper foam cooling water tank continuous casting crystallizer copper plate:
[0034] Such as Figure 1-Figure 3 As shown, the copper plate of the continuous casting crystallizer in the foam copper cooling water tank includes: a copper plate body 1, and the opposite surfaces of the copper plate body 1 are the copper plate working surface 7 and the copper plate cooling surface 3 respectively. Among them, the cooling surface 3 of the copper plate is used to connect with the fixed water tank or the transfer back plate, and is used to realize back cooling; and the working surface 7 of the copper plate is used for continuous casting of metal.
[0035] The copper plate body 1 is provided with a plurality of foamed copper cooling grooves 2 , fixed ribs 4 , pin bolt screw holes 5 and pin bolt table tops 6 on the copper plate cooling surface 3 .
[0036] The copper foam cooling tank 2 is embedded with copper foam, which is pure copper and has a porous...
Embodiment 2
[0043] The present embodiment provides a kind of preparation technology of foamed copper cooling water tank continuous casting crystallizer copper plate:
[0044] S1: Select high-temperature-resistant and water-soluble salt particles according to porosity and pore size, arrange the salt particles in the cavity and compact them, pour molten metal copper, control the pouring temperature at 1200°C to 1300°C, perform infiltration casting, and cool Afterwards, the salt desolventization treatment is not carried out to obtain an open-cell foamed copper billet without salt desolventization treatment. Carry out operations such as wire cutting to it again, obtain the non-salted presolvation treatment foamed copper mold core 8 of required size, as Figure 4 shown. Wherein, the front surface 9 of the unsalted copper foam billet is flat, which facilitates making the copper foam prepared on the cooling surface 3 of the copper plate flat and reduces processing difficulty. The copper foam c...
Embodiment 3
[0049] The present embodiment provides a kind of preparation technology of foamed copper cooling water tank continuous casting crystallizer copper plate:
[0050] S1: Select the open-cell copper foam billet with the required porosity and pore size, put it into the mold cavity, and preheat it. Control the preheating temperature to 600°C to 700°C, pour molten aluminum water, and control the melting temperature to 700°C ~800°C, pressurize to fill the pores of copper foam with molten aluminum water, and obtain open-cell copper-aluminum composite blanks after cooling; perform wire cutting and other operations on the obtained copper-aluminum composite blanks to obtain the required size Foamed copper-aluminum composite core 11, such as Figure 5 As shown, the front face 12 of the copper foam-aluminum composite core is flat, which facilitates making the copper foam prepared on the cooling surface 3 of the copper plate flat and reduces processing difficulty. Foamed copper-aluminum com...
