Description

Technical Field

[0001] The utility model relates to the technical field of thermal bursting performance detection, in particular to a novel ore thermal bursting performance detection device. Background Art

[0002] Hot bursting is a key metallurgical property of iron ore. Ore with a high hot bursting index will lead to increased dust emissions and deterioration of blast furnace performance during blast furnace smelting, necessitating the control of the proportion of this ore in the charge. This demonstrates the importance of hot bursting in blast furnace operation.

[0003] The current thermal cracking performance testing device places the lump ore sample in a test box, which is then placed on a molybdenum plate. The molybdenum plate is then transported into the furnace using a forklift, which is then lowered to position it horizontally on four bases. However, since the bases are placed directly on the refractory bricks of the furnace, if the forklift is not at the right height when inserting and exiting the furnace, the bases can easily fall. If even one base falls, the molybdenum plate cannot remain stable, which can easily lead to the plate breaking or the test box tipping over, forcing the test to stop. In addition, during the test, the temperature inside the furnace drops to 700°C, and the bases can only be raised after it cools down naturally. This process is time-consuming and labor-intensive, seriously affecting the test efficiency. Therefore, the above problems need to be solved urgently. Summary of the Invention
