Influencing factors of oxidation in heating process based on SAE1070 steel
The oxidation of SAE1070 steel during heating process has a great influence on the product quality and the energy consumption of heating furnace. In this paper, a formula for calculating the thickness of oxide layer of SAE1070 steel is presented based on previous experimental results. The influence of furnace parameters such as heating temperature, heating time and oxygen volume fraction on the oxidation of SAE1070 steel is considered in the formula. The variation of the thickness of oxide layer of SAE1070 steel with heating temperature, heating time and oxygen volume fraction is also analyzed. The main results show that when the volume fraction of oxygen in flue gas is 3％, the thickness of oxide layer is 1. 3 times that of 1％. In the design and actual control of the furnace, the structure and control strategy of the furnace can be optimized according to the above research results.
