Aluminum is widely used in all aspects of production and life because of its corrosion resistance, high specific strength and specific stiffness, low density, easy forming and energy saving. It is an important [url=http://affordablefloorswa.com/sale/377.html]alternative fence panels[/url] basic material for the development and progress of the national economy , Especially in the structural and decorative applications almost irreplaceable, and flat aluminum extruded profiles also play an important role in promoting social and economic development. Water jet cooling is an important process for the production of aluminum extrusion profiles, aluminum extrusion profiles of the water cooling process directly determines the mechanical strength of the profile.

In order to improve the mechanical strength of the profile, after rapid cooling of many profiles, the cooling equipment is also required to ensure uniform distribution of the temperature profile of the flat aluminum profile in the direction of length, width and [url=http://affordablefloorswa.com/long-life/3811.html]picnic pavilion kits[/url] wall thickness. 1 extrusion speed of the impact The extrusion speed of the aluminum extrusion is usually expressed as the speed at which the metal flows out of the die orifice. The extrusion speed affects mainly the temperature distribution in the longitudinal direction, while the temperature distribution in the smaller width direction is negligible. Therefore, The variation of the temperature distribution in the lengthwise direction under different extrusion velocities was discussed.

Through the analysis, it is found that the temperature difference between two ends of [url=http://affordablefloorswa.com/durable/1306.html]material to put under composite decking[/url] extruded aluminum profile is getting smaller and smaller as the extrusion speed increases, while the temperature change is smaller when the extrusion speed of 10mm / s is increased to 40mm / s, That is to say, the temperature distribution in the longitudinal direction of the extruded aluminum bar is more and more uniform with the increase of the extrusion rate.

However, when it is increased to 40 mm / s, the influence on the temperature field in the longitudinal direction will be more It can be said that there is a critical value of squeezing speed on the temperature field of spray cooling of flat aluminum extrusion profiles. The critical value is 40 mm / s at this time. If the squeezing speed is less than the critical value, The influence of the field is larger, but if the squeezing speed is greater than the critical value, its influence on the temperature field is [url=http://affordablefloorswa.com/long-life/350.html]how to build a 4 foot wide wooden fence gate on youtube[/url] getting smaller and smaller.
