鋁棒加熱擠壓的流程均化

鋁棒在進入擠壓機之前是要預加熱的。傳統觀念也許,鋁棒必須在加熱爐內加熱到固溶溫度,鋁卷○但經驗顯示這不是一定的。只要鋁棒被正確的鑄錠和均化,就沒有必要在鋁棒預熱爐里達到固溶溫度。在現代鋁擠壓工廠里大馬力生產,鋁棒加熱…
The aluminum bar should be pre heated before entering the extruder. The traditional idea is that aluminum rods must be heated to the solid solution temperature in the reheating furnace, but the experience shows that this is not necessarily. As long as the aluminum bar is properly inlaid and homogenized, it is not necessary to achieve the solid solution temperature in the aluminum rod preheating furnace. In the modern aluminum extrusion plant, the production of large horsepower, the heating of aluminum rods.

The aluminum bar should be pre heated before entering the extruder. Traditionally, aluminum rods must be heated to a solid solution temperature in a furnace, but experience shows that this is not necessarily true. As long as the aluminum bar is properly inlaid and homogenized, it is not necessary to achieve the solid solution temperature in the aluminum rod preheating furnace. In the modern aluminum extrusion plant, the only purpose of the furnace is to soften the metal. If the metal is not heated enough to sell aluminum rolls, the formula for the calculation of aluminum rolls will not be able to pass the mold smoothly. If the aluminum bar is overheated and effectively released, the typical problems of temperature measurement in the preheating zone of aluminum rods are:
兩點式的熱電偶讀數會偏低
A two point type of thermocouple will be on the low side
兩點式熱電偶的日常維護經常被忽略
The daily maintenance of a two point thermocouple is often ignored
均勻化熱處理溫度是鋁棒的關鍵參數
The temperature of homogenizing heat treatment is the key parameter of aluminum rod

鋁板生產廠家
操作者傾向于過度加熱鋁棒
The operator tends to overheat the aluminum rod
操作者傾向于降低擠壓速度來微調鋁棒在擠壓中的溫度變化
The operator tends to reduce the extrusion speed to fine tune the temperature changes of the aluminum bar during extrusion.
過度加熱和慢速擠壓都浪費了預熱的能源
Excessive heating and slow extrusion waste the energy of preheating.
鋁棒應該加熱到能夠擠壓的較低溫度,鋁卷銷售規格表同時必須保證擠壓機出口的溫度達到目標值。通過降低鋁棒預熱溫度,擠壓速度就可以提上來,⒀鋁卷銷售價格這樣加熱爐的能量消耗就會減少。實踐證明經濟數據,這樣的改變能節省燃氣加熱爐15-20%的能耗。
The aluminum bar should be heated to the lowest temperature that can be extruded. The aluminum roll sales specification must also ensure that the outlet temperature of the extruder reaches the target value. By reducing the preheating temperature of the aluminum bar, the extrusion speed can be raised, and the energy consumption of the reheating furnace will be reduced. Practice has proved that economic data can save energy consumption of 15-20% in gas fired furnace.
對于燃氣加熱爐廉價進口產品,鋁棒區間溫度是使用兩點式的熱電偶測溫。因為這類儀表對維護都有很高的要求,Ⅴ使用這樣一臺儀表本身的優越性,要么會花費很高維護費鋁卷銷售,鋁卷銷售試驗報告要么會失去精確度。一些鋁擠壓廠已開始使用非接觸式傳感器檢測和控制鋁棒區域加熱段的溫度。不但減少了對接觸式熱電偶測溫計的依賴,⒇而且減少了因儀表本身局限性帶來的維護問題和精確度問題。
For the cheap imported products of gas heater, the temperature of the aluminum rod is measured by two point thermocouple. Because such instruments have high requirements for maintenance, V. using the superiority of such an instrument itself, or the high cost of maintenance of aluminium rolls, the aluminum volume sales test report will either lose accuracy. Some aluminum extrusion plants have started using non-contact sensors to detect and control the temperature of the heating section of the aluminum rod region. It not only reduces the dependence on the contact thermocouple thermometer, but also reduces the maintenance and accuracy problems caused by the limitations of the instrument itself.
