冷却效果

It has been found that there are some texture flaws such as large grain、badly distorted twin and streaky structure. But recrystallization grains ofaround 19μm in diameter on average are obtainable through heat treatment at300℃for 30min by air-cooling, meanwhile the twin and streaky structurethat would weaken the plasticity of alloy are eliminated; significant elementsare holding temperature、holding time、cool-down methods. Mechanicalproperties of tube are obtained, simple tension elongation ratio of arc testsample increases from 10.8% to 20.1%, elongation ratio with elastic internaldie of tube increases from 8.0% to 14.9%.

The results show that the turbulence intensity, fouling cleaning intensity and pressure drop increase with the increase of flow velocity, particle size and the volume fraction. The effect of liquid-solid fluidzed-bed cleaning fouling depends on the reasonable combination of flow velocity, particle size and the volume fraction. Through an integral consideration of water saving and energy saving and uniformity of fouling cleaning, the optimum flow velocity of flow, particle size and volume fraction are 2.0 m/s~2.5 m/s, 3 mm~4 mm and of 5%~8 vol%, respectively.
