6-50wt% magnesium alloy, between being heated to 500-850 DEG C by heating furnace, 5-8wt% granularities are added between 185-300 mesh
Foaming agent carbonate, and after the tackifier of 0.5-3.5wt% high-purity alpha-SiC particle preparations, stirred with 1000-1500r/min speed
2-15min is mixed, Ar or CO is passed through in whipping process2Hybrid protection gas, injected after being incubated 5-20min on ceramic composite membrane directly
Cooling, obtains blade substrate, then sprays resistance to erosion corrosion-resisting resin film on blade substrate again.
9. device according to claim 8, it is characterised in that the blade averag density is in 0.5-2g/cm3Between, compare table
Area is 10-40cm2/cm3, porosity is between 20%-70%, and pore size control is between 100 μm -500 μm, intensity 55-
360MPa;The thickness 0.5mm-1.5mm of resin film.
10. the method for the generating of steel plant's cooling tower recirculated cooling water TRT according to claim any one of 1-9,
Characterized in that, this method comprises the following steps that：
After TRT is installed, when cooling water by water distributor spray after packing layer falls into rain belt, fall on composite blading,
Because the angle of composite blading and horizontal direction is 5-50 °, gravitional force is converted into kinetic energy, drives composite blading to revolve
Turn, while drive generator to rotate, convert mechanical energy into electric energy, electric energy enters electric power storage after being changed by current rectification inverter
Pond is connected to the grid；
The water for driving composite blading to rotate loses heat in descent, and temperature reduces, then drops into collecting-tank and assemble,
It is pumped into again by water pump in each circulating line and flows to each heat transmission equipment.
