 鋁棒在進入擠出機前進行預熱。傳統觀念,也許㊣酒吧必須在爐內加熱固溶溫度、鋁卷但經驗表明,現在還不確定。只要鋁棒澆鑄正確、均勻化,無需在預熱爐中達到固溶溫度。
  The aluminum bar is preheated before entering the extruder. Traditionally, bars may have to heat solution temperature and aluminum coil in the furnace, but experience shows that it is still uncertain. As long as the aluminum bar is cast correctly and evenly, it is not necessary to reach the solution temperature in the preheating furnace.
  鋁棒在進入擠出機前進行預熱。傳統的想法,也許,爐內的酒吧必須加熱到固溶溫度、Ⅻ但經驗表明,現在還不確定。只要適當的澆鑄和均勻化,就不需要在預熱爐中達到固溶溫度。鋁棒爐的唯一用途是軟化金屬,而不是在現代的鋁擠壓廠生產。如果金屬加熱對鋁盤管的銷售不夠,鋁盤管的銷售計算公式不能順利通過模具。如果要有效地釋放鋁棒時,加熱,擠出速度必須非常低。


  The aluminum bar is preheated before entering the extruder. The traditional idea, maybe, is that the bar in the furnace must be heated to the solution temperature, ? but experience shows that it is still uncertain. As long as the proper casting and homogenization, it is not necessary to reach the solution temperature in the preheating furnace. The only purpose of the aluminium bar furnace is to soften the metal, not to be produced in modern aluminium extrusion plants. If the sales of aluminum coil by metal heating is not enough, the sales calculation formula of aluminum coil can not pass the mold smoothly. If the aluminum bar is to be released effectively, the extrusion speed must be very low.
  鋁棒預熱區溫度測量的典型問題有:
  Typical problems of temperature measurement in preheating zone of aluminum bar are as follows:
  1. 兩點熱電偶讀數將較低
  1. Two point thermocouple reading will be low
  2. 兩點熱電偶的日常維護經常被忽略
  2. Routine maintenance of two-point thermocouple is often ignored
  3.均勻化熱處理溫度是鋁棒的關鍵參數
  3. Homogenization heat treatment temperature is the key parameter of aluminum bar

 


  4. 操作員容易使鋁棒過熱
  4. The operator is easy to overheat the aluminum bar
  5. 操作者傾向于降低擠壓速度來微調鋁棒在擠壓過程中的溫度變化
  5. The operator tends to reduce the extrusion speed to fine tune the temperature change of aluminum bar during extrusion
  6. 過度加熱和緩慢擠壓浪費預熱能量
  6. Excessive heating and slow extrusion waste preheating energy
  棒材應加熱到可擠壓的更低溫度。線圈銷售規格還必須確保擠出機出口溫度達到目標值。通過降低鋁棒的預熱溫度,可以提高擠壓速度,鋁盤管的銷售價格可以降低加熱爐的能耗。實踐證明,這種經濟數據的改變,可以節省燃氣加熱爐15-20%的能源消耗。
  The bar shall be heated to the minimum temperature at which it can be extruded. The coil sales specification must also ensure that the extruder outlet temperature reaches the target value. By reducing the preheating temperature of the aluminum bar, the extrusion speed can be increased, and the sales price of the aluminum coil can reduce the energy consumption of the heating furnace. The practice shows that the change of economic data can save 15-20% energy consumption of gas heating furnace.
  針對燃氣加熱爐進口廉價產品,采用兩點熱電偶測量鋁棒的溫度范圍。因為這種儀器維護要求高,Ⅴ使用這種儀器本身的優點,還是非常昂貴的維護鋁卷銷售、鋁卷銷售測試報告或失去準確性。一些鋁型材廠已經開始使用非接觸式傳感器來檢測和控制鋁型材加熱段的溫度。不僅減少了依賴聯系熱電偶溫度計,⒇,減少了維護問題由于儀器本身的局限性和準確性。
  Aiming at the imported cheap products of gas heating furnace, the temperature range of aluminum bar is measured by two-point thermocouple. Because of the high maintenance requirements of this instrument, v. the advantages of using this instrument itself, or very expensive maintenance aluminum sales, aluminum sales test report or loss of accuracy. Some aluminum profile factories have begun to use non-contact sensors to detect and control the temperature of the heating section of aluminum profile. It not only reduces the dependence on contact thermocouple thermometers, but also reduces the maintenance problems due to the limitations and accuracy of the instrument itself.
  在感應加熱爐系統中,紅外溫度傳感器直接對準鋁棒的表面來引導力,第七個可以直接了解溫度“產生和推進”,而第四個可以減少兩點熱電偶使用的不一致性。同樣,為燃氣熱水器,傳感器可以安裝在爐出口(擠壓管入口)理解鋁棒的表面溫度,Ⅱ也用于正確的爐內的溫度熱電偶或紅外測溫儀溫度偏差。鋁棒溫度測量部分酒吧是更理想的位置,Ⅵ檢查均熱段溫度。側部的溫度也要測量,因為這一側會先接觸模具。
  In the induction heating furnace system, the infrared temperature sensor directly aims at the surface of the aluminum bar to guide the force, the seventh can directly understand the temperature "generation and propulsion", and the fourth can reduce the inconsistency of the use of two-point thermocouples. Similarly, for the gas water heater, the sensor can be installed at the furnace outlet (extrusion pipe inlet) to understand the surface temperature of the aluminum bar. II is also used for the correct temperature thermocouple or infrared thermometer temperature deviation in the furnace. Aluminum bar temperature measurement part of the bar is the most ideal location, Ⅵ check the soaking temperature. The temperature of the side should also be measured, because this side will contact the mold first.
  對于梯度加熱的鋁條,可以在鋁條輸送帶一側安裝一個傳感器來了解鋁卷銷售的溫度,也可以安裝兩個傳感器來測量鋁條兩端的溫度。準確的梯度加熱溫度對連續輸送鋁棒到擠出機是非常重要的。不準確的溫度測量會使梯度加熱失去意義。
  For the gradient heating aluminum strip, a sensor can be installed on one side of the aluminum strip conveyor belt to understand the sales temperature of the aluminum roll, or two sensors can be installed to measure the temperature at both ends of the aluminum strip. Accurate gradient heating temperature is very important for the continuous transportation of aluminum bars to the extruder. Inaccurate temperature measurement will make gradient heating meaningless.
