Packaging steel strip is a material that we often use in the industry. Then, do you know that there are a lot of detailed matters in the production process of plated packaging steel strip. Below, let me introduce it in detail:
1. Controlling the annealing medium: the usual annealing medium used by the manufacturer is pure hydrogen, and the purity of the medium is preferably above 99.99%. If the other part of the medium is an inert gas, the purity can also be lower. However, we must not be careful Contains too much oxygen and water vapor.
2. The annealing temperature is well grasped: check whether the annealing temperature can reach the specified temperature in time, our annealing adopts a capacitive heat treatment, that is, we can observe the condition of the strip steel in the annealing zone as incandescent through the annealing furnace.
3. Regularly check the ranking of water vapor in the furnace to see if the materials in the furnace body are dry. If it is the first time to install the furnace, the furnace body must be dried to avoid excessive water stains on the bright strip steel in the furnace.
4. You must cherish the sealing performance of the furnace body to ensure that it is not in contact with the outside air. We can test the furnace body of the annealing furnace with soapy water.
5. Place the gas exposed and cherish the gas pressure.
