Control temperature to ensure smooth surface of aluminum alloy

1. In the traditional hot rolling process, handheld thermocouples are used to measure the temperature of the intermediate slab and hot-rolled coil of the ingot, and the temperature measurement method of the aluminum coil is post-measurement. Now the hot rolling machine is arranged and controlled at various temperature measurement points on the production line.

There is temperature measurement before entering the furnace. The temperature before the rough rolling start is measured after the ingot is out of the furnace.

2. Temperature measurement is required before post-inspection. The temperature after the rough rolling head and tail is mainly used for detection. The measured temperature is used to control the rolling pass of the head and tail to ensure the target rolling temperature of the rough rolling, and the continuous rolling table is preset for the second time.

3. Temperature measurement is required before thin shearing. During production, a pyrometer is used to measure the temperature to save production assistance. Contact thermocouples are used regularly to measure and calibrate the thermometer.

4. Temperature measurement at the outlet of the continuous rolling mill. The main purpose and use is to produce high-quality, efficient, and low-consumption aluminum alloy hot-rolled aluminum strips aluminum plates, and aluminum coils.

5. Control and measurement of aluminum coil temperature. The temperature measurement of aluminum coils uses two sets of contact temperature measurement, which is used to calibrate the temperature at the outlet of the continuous rolling mill.
