Heat preservation protective device for molten iron tank of molten iron vehicle

Abstract

The invention relates to a heat preservation protective device for a molten iron tank of a molten iron vehicle, and belongs to the technical field of iron and steel enterprise molten iron vehicle devices. The device is used for preserving the heat of transported molten iron. According to the technical scheme, a protective cover is composed of two relative semicircular cover bodies, the two semicircular cover bodies are in butt joint and are matched with the top surface and the outer periphery of an opening in the upper end of a molten iron tank, the upper ends of two supporting frames are connected with the two semicircular cover bodies of the protective cover correspondingly, the lower ends of the two supporting frames are connected to the front end and the rear end of the molten iron tank of a molten iron vehicle through vehicle body hinging seats, two hydraulic cylinders are arranged at the front end and the rear end of the molten iron vehicle, the lower ends of the hydraulic cylinders are connected with the vehicle body, the front ends of hydraulic push rods of the hydraulic cylinders are hinged to the middles of the supporting frames, and the hydraulic cylinders are connectedwith hydraulic pumps. The device has the beneficial effects that the excessive temperature drop of the molten iron in the molten iron tank of the molten iron vehicle can be avoided, the smooth proceeding of the subsequent steelmaking process is guaranteed, the production efficiency is improved, the molten iron in the molten iron tank can be protected from being influenced by external factors, andthe safety of the device and personnel is guaranteed.

Description

technical field [0001] The invention relates to a heat preservation and protection device for a molten iron vehicle used for transporting molten iron between two processes of ironmaking and steelmaking in an iron and steel enterprise, and belongs to the technical field of equipment for an iron and steel enterprise. Background technique [0002] In iron and steel enterprises, the part or transition process between the two processes of ironmaking and steelmaking is usually called the iron-steel interface in the industry, that is, the interface between the blast furnace and the converter. Pretreatment, empty bag transportation, pretreatment, empty bag transportation and many other links. In the iron-steel interface, a large number of molten iron trucks are required to transport molten iron, on which molten iron tanks are installed, and the molten iron is transported from the molten iron tanks to the steelmaking department. Due to the relative distance between the blast furnace...

AI Technical Summary

Problems solved by technology

Due to the relative distance between the blast furnace and the converter in many iron and steel enterprises, the temperature loss during transportation is relatively large. The temperature of molten iron drops due to the heat dissipation of the molten iron tank. Excessive temperature drop of molten iron will not only cause heat loss and waste, but also affect the subsequent pretreatment of molten iron. and steelmaking process, and in severe cases, production scheduling and iron ladle life will be affected due to the occurrence of condensation

In the actual production process, it is found through research that the empty iron tanks of the molten iron trucks spend most of the time in the standby state, and the temperature of the molten iron tanks drops greatly.

When filled with molten iron, the molten iron tank will absorb heat, causing the temperature of the molten iron to drop aggravated, affecting subsequent steel production, so it is urgent to improve the existing molten iron car

Another disadvantage of the current hot metal car is that molten iron may splash out during transportation, threatening the safety of the hot metal car, people and facilities along the way, and must be improved
