The internal folding problem of the glass-lined reactor means that the quality of the equipment is not up to standard, which cannot be purchased and used. When purchasing glass-lined reactor equipment, you must do a good job of inspection to ensure that there is no problem with the equipment before purchasing, otherwise, once you buy a fake and shoddy reactor, it will be over.
The relationship between the heating time of the glass-lined reactor and the inner folds, when the heating time is constant, has little effect on the inner folds, but the number of outer folds increases significantly. The reason is that the longer the heating time, the stronger the grain growth, and the It is the surface layer that is more obvious, which deteriorates the tissue properties and causes outward folds. The influence of the tool on the inner fold, the head also has a certain influence on the inner fold.
The influence of piercing temperature on inward folding, with the increase of temperature, the plasticity of the material increases, and the critical reduction increases with the increase of temperature, but if it is a tube billet cast with a better casting temperature, the piercing temperature changes within a certain range. There is no significant change in the time-in-fold.
