<p>the upper and lower horizontal row of three rows of nozzles is more reasonable, that is, along the width of the center line up and down a row of nozzles. 3 Longitudinal nozzle spacing influence  hollow fence posts outlet world  Longitudinal nozzle spacing mainly affects the temperature distribution in the longitudinal direction, while the influence of the width direction of the temperature distribution is negligible, as long as the length of the temperature variation in different nozzle longitudinal spacing of the impact were discussed. </p> <p>The temperature difference between the two ends of the flat aluminum extruded section increases with the longitudinal spacing of the nozzles. In other words, the longitudinal temperature distribution of the flat aluminum extruded section will be more obvious how to install manufactured hardwood in threshholds   with the increase of the longitudinal spacing of the nozzles. The longitudinal temperature The distribution will be more and more uneven, the longitudinal nozzle spacing should be less than 50mm. </p> <p> The impact of water temperature Two rows of nozzles to implement the program, that is, flat aluminum extruded profiles are arranged on the top and bottom of the two rows of nozzles, and the nozzle spacing between the values of 60mm. The study on the curve of spray cooling temperature on the upper surface length and the width direction centerline of flat aluminum extruded profiles shows that the temperature of flat extruded aluminum profiles will increase with the increase of cooling water temperature but not too Affect the uniformity of the temperature  game fencing estimates in south africa  distribution. </p> <p>That is to say, the flat aluminum extruded profile cooling effect less affected by the water temperature. In summary, the temperature field in the width direction is less affected by the extrusion speed and the temperature field in the length direction is greatly affected, and the temperature field has a  diy cheap outdoor flooring ideas critical value affected by the extrusion speed.</p>
