The 2A12 aluminum bar needs to be preheated before entering the extrusion press. Only when it is heated to a certain temperature can it enter the extrusion press. Today, the 2A12 aluminum bar manufacturer will introduce to you the common problems in the preheating process of the 2A12 aluminum bar and give suggestions for solving them.

There are problems in the preheating temperature of aluminum bar: 1. The reading of two-point thermocouple will be too low; 2. The daily maintenance of two-point thermocouple is often ignored; 3.Homogeneous heat treatment temperature is the key parameter of aluminum bar 4. Operators tend to overheat aluminum bar 5.Excessive heating and slow extrusion waste energy.

The 2A12 aluminum bar shall be heated to a low temperature at which it can be extruded, while ensuring that the outlet temperature reaches the set value.By reducing the preheating temperature of the 2A12 aluminum bar, the extrusion speed can be increased, energy consumption can be reduced, and 15-20% gas can be saved.

The temperature of the aluminum bar is measured by a two-point thermocouple.This kind of instrument has a high maintenance cost. At present, non-contact sensor is used to detect and control the temperature of the heating section of the aluminum bar area.In the induction heating furnace system, the temperature can be directly monitored through the surface of 2A12 aluminum bar, reducing the inconsistency of two-point thermocouple.Similarly, for a gas heating furnace, a sensor can be installed at the furnace outlet (the inlet of the squeeze tube) to monitor the temperature on the surface of the 2A12 aluminum bar. The ideal location for measuring the temperature of the 2A12 aluminum bar material is the section of the 2A12 aluminum bar to check the temperature in the soaking zone.

For the gradient heated 2A12 aluminum bar, a sensor can be mounted on the side of the aluminum bar conveyor belt to monitor the temperature. The precise gradient heating temperature is important for the continuous transfer of the aluminum bar into the extruder.
