Description

Technical Field

[0002] Sampling and testing molten steel during the steel smelting process is an important link in the production process. After sampling, it needs to be sent to the laboratory for grinding and testing of components. Because the temperature of the molten steel sampled from the smelting furnace is relatively high, it needs to be cooled. The traditional cooling method is water cooling, that is, a cooling water tank is placed around the smelting furnace, and the sampling tube is immediately placed in the cooling water tank for circulating water cooling after taking out the high-temperature molten steel. However, high-temperature molten steel is prone to explosion when it meets water, which poses a major safety hazard to the management and safe production of high-temperature molten metal areas. At the same time, after sampling, a handheld mechanical device is required to place the sampling tube into the cooling device, and after cooling, the sampling tube needs to be taken out of the cooling device again by a handheld mechanical device. Since the molten steel in the sampling tube is in a high-temperature state and the cooling device is in a low-temperature state, taking and placing the sampling tube by a handheld mechanical device may pose a certain safety threat to on-site operators.
