Method for preventing molten iron of torpedo tank from being sprinkled due to reverse rotation

Abstract

The invention provides a method for preventing molten iron of a torpedo tank from being sprinkled due to reverse rotation. According to the method, a trigger baffle is arranged at the position of the maximum diameter of a tank body on the reversal side of the torpedo tank; a travel switch with a trigger touch plate is arranged on a wall opposite to the trigger baffle; a trigger rod is hinged to the front end of a support below the travel switch; the travel switch is connected with a contactor connected with a torpedo tank tipping power electric circuit and is in the closed state in the normal state; when the torpedo tank rotates reversely, the trigger baffle triggers the travel switch by the trigger rod and the trigger touch plate, so that the travel switch is turned off; and the contactor and the tipping power electric circuit which are connected with the travel switch are powered off, so that the torpedo tank stops rotating reversely. By the method, the problem of the reverse rotation of the torpedo tank due to misoperation or the failure of equipment components during the pouring of the molten iron can be avoided fundamentally, iron sprinkling accidents are eliminated, the loss of the accidents is avoided, the service life of the travel switch is prolonged, and the running reliability is improved.

Description

technical field [0001] The invention belongs to the field of smelting machinery and equipment, and in particular relates to a method for preventing a torpedo tank from being reversely rotated during iron folding and causing iron spilling. Background technique [0002] The steelmaking plants of large-scale iron and steel complexes all have special can dumping workshops. In the can dumping workshops, two torpedo tank car conveying lines are generally installed, and the molten iron tanks to be ironed are parked in the middle of the two torpedo tank car running tracks. Therefore, one is that the torpedo tank must have the function of forward and reverse (two-way) rotation; the other is that no matter which track the torpedo tank car is parked on, the torpedo tank can only be folded to the inner side of the track, that is, the iron ladle tank. . If it is tilted outward (generally referred to as reversal), the molten iron cannot fall into the molten iron tank, and iron sprinkling...

Problems solved by technology

However, in the actual production process, there are often human error operations or equipment failures, which make the detection of the zero limit signal distorted. The torpedo tank zero limit signal is interlocked with the operating system to prevent iron spilling. The reliability of the control method is not high, and there is obviously a huge potential safety hazard.
