Precautions For Use Of High Temperature Explosion-proof Steel Ladle Transfer Car
2019-03-30Precautions For Use Of High Temperature Explosion-proof Steel Ladle Transfer Car
1.How high can the ladle transfer car withstand?
A: Although the temperature of the molten steel is very high, the ladle itself has the function of heat insulation. Therefore, the surface temperature of the ladle is generally over 200 °C, and radiation to the environment will not affect the electrical components.
2.When the ladle transfer car starts and stops, will the molten steel spill out due to inertia?
A: No. The motor used in the hot metal ladle transfer car is usually a soft-start motor, and it is usually controlled by frequency conversion. It will also have a delay function when stopping, so it will accelerate slowly when starting, until the set speed is reached. Perform uniform motion. After the power is turned off, perform a uniform deceleration motion until it stops. Therefore, no dangerous accidents will occur due to inertia.
3.What are the differences between the ladle transfer cart and the ordinary electric flat car?
A: The model is somewhat different in structure from ordinary electric flat cars. Firstly, the height of the ladle is at least 1m, and there are dangerous goods such as molten steel inside. In order to minimize the center of gravity of the ladle, the countertops of the ladle are mostly hollowed out. The ladle is placed in the depression of the table top, and a beam is arranged on the table surface, and the position of the ladle hanging hole can be placed on the surface to increase the bearing capacity. Secondly, in order to adapt to the harsh environment of the steelmaking furnace, the configuration of the motor and reducer of the ladle transfer car is higher than that of the ordinary transfer cart, and usually two sets of drive systems are used, so that a set of drive systems may be faulty. Avoid the condensation of molten steel in the ladle due to the stop of the flat car movement, which can reduce the loss of the enterprise.
