Problems solved by technology

According to foreign data, the heat loss of the covered ladle is very low throughout the whole process. Even if the online rapid baking of the ladle is cancelled, the tapping temperature can still be reduced by more than 15°C; the use of this system fundamentally solves the problem that has been plagued by people. : During the transfer process of covered ladle / hot metal tank, the operation of adding and removing the lid will change the existing logistics, increase the operation time of the crane, change the operating habits and prolong the smelting time and other unfavorable situations

Embodiment Construction

[0024] Figures 1 to 9 It is a specific embodiment of the present invention, combined with Figures 1 to 9 described as follows:

[0025] ginseng figure 1 and 2, the power of the latch mechanism 4 comes from the squeezing force generated by the relative movement of the latch mechanism lever 44 and the dial block 3, and is transmitted to the interacting spring 41, counterweight 42, latch 45 and its drag chain through the rotating shaft 43; The power can also be used to open and reset the thermal insulation cover 12 with a small hinge; the double-hinge hooks (12 and 13) are both hanging ear mechanisms with inverted U-shaped grooves, which not only play the role of convenient installation and adjustment, but also digest The notch of the large hinge hook 13 also plays a guiding role in the process of adding and uncovering the cover, so that the composite cover 1 runs smoothly and the vibration is reduced, thereby effectively prolonging the service life of the refractory lining o...

Abstract

The invention relates to a plug-pin type double-hinge compound cover system, belonging to the technical reform field of special container for transportation. The system comprises five subsystems of a composition cover (1), a hinge seat (2), a door-shaped hook beam shifting block (3), a plug pin mechanism (4) and a fixing fork finger mechanism (5). In the invention, an external force and a simple and practical pure mechanical mechanism are ingeniously adopted, so that the opening operation, the self-locking protection operation and automatic opening-closing operation of a thermal insulating cover can be carried out without changing the present logistics, or prolonging crown block operation time or operation customs but remaining the original production rhythm, and the final goals of energy saving, consumption reduction and efficiency improvement are achieved. The direct benefit of the system lies in that the initial temperature of molten iron pretreatment is increased by about 40 DEG C, and the tapping temperature of a converter is decreased by over 15 DEG C.

Description

technical field [0001] The invention belongs to the technical transformation field of special containers for transportation, and particularly provides a bolt-type double-hinge composite cover system. Background technique [0002] At present, in high-temperature smelting occasions, in the process of transferring liquid water or molten slag, barrel containers are still the main containers. The molten steel from the electric furnace is used as a ladle as a container. There are two ways to transfer them between processes: ground and air. Ground transportation is realized by special locomotives, automobiles or transport trolleys. Air transportation basically occurs indoors, such as the cast iron room of the iron factory, the molten iron span of the steel factory, and the molten steel. Accepting spans and maintenance spans are hoisted and transferred by metallurgical cranes or special maintenance cranes. With the rapid promotion of various new molten steel refining technologies ...
