Description
Technical Field
The invention relates to a tank opening device of molten iron transportation and storage equipment, in particular to a detachable tank cover suitable for a torpedo type iron mixing vehicle and a manufacturing method thereof.
Background
The torpedo type hot metal mixer car, called as hot metal mixer car for short, is a large-scale molten iron transportation device, has the advantages of small heat loss, long heat preservation time, energy conservation and the like, and can also store molten iron so as to coordinate the temporary unbalanced state of iron making and steel making. Meanwhile, the mixer car can replace a mixer furnace and a common molten iron tank car for steel making, and can also complete the operation procedures of desulfurization, dephosphorization and the like in the molten iron transportation process.
In the process of transporting molten iron, the mixer car generally needs to be subjected to the stages of iron receiving, molten iron pretreatment, slag skimming, waiting, iron dumping, empty tank transportation and the like, the molten iron transportation and waiting time is long, the molten iron temperature is high, and the molten iron heat is lost in three modes of heat conduction, heat radiation and heat convection. Relevant researches show that the heat storage loss of the tank lining, the heat dissipation of the tank wall and the radiation heat loss of the molten iron surface respectively account for 45% -50%, 20% and 20% -30% of the total heat loss, wherein the radiation heat loss of the molten iron surface is mainly the heat loss of the tank opening. The longer the transportation and waiting time are, the larger the temperature drop of molten iron is, the too large temperature drop of molten iron can cause the bottom of the iron mixing car to be in the states of bottom formation, crusting and even the whole iron mixing car to be frozen, and the too large temperature drop can cause the great increase of the energy consumption of the steel making process, thereby causing great economic loss for enterprises. In addition, with the improvement of environmental protection requirements, the tightening of energy-saving policies and the enhancement of law enforcement, steel enterprises are required to continuously enhance the awareness of energy conservation and environmental protection. At present, the iron mixing vehicle used in China has the problems that the temperature drop of molten iron is accelerated and the heat loss is increased due to the fact that a tank car is opened, and a large amount of dust and smoke generated in a tank body are directly discharged into the atmosphere, so that the surrounding environment is polluted. Therefore, the hot metal mixer truck is a development direction of hot metal transportation and storage equipment in the future by covering and insulating the hot metal mixer truck to reduce the heat loss of the hot metal and prevent the smoke and dust from being directly discharged into the atmosphere, and the traditional uncovered hot metal tank truck can not meet the requirements of users any more.
Chinese patent CN103949630B discloses a heat preservation cover for sealing a metal mixer car tank opening, wherein inner and outer layer refractory materials are connected and laid in a steel plate with a circular groove through riveting pieces to form a tank cover main body, the steel plate is provided with a stepped hole, and a honeycomb-shaped heat-resistant body and a rain shield are arranged above the stepped hole. This heat preservation lid can effectively reduce the radiation heat dissipation of molten iron through the jar mouth, can stabilize jar internal gas pressure through the shoulder hole setting and reduce the thermal shock to the heat preservation lid, nevertheless heat preservation lid main part is pour by steel sheet and ectonexine refractory material and forms, and weight is big, needs the special hoisting accessory of installation to carry out opening and closing of heat preservation lid, has investment cost height, on-the-spot space not enough scheduling problem, and is difficult to the manual work under the equipment fault condition and opens and close. Chinese patent CN105272301A discloses a torpedo ladle lid lining and a preparation method thereof, the lining is composed of a coating and a castable body, the coating is made by mixing and ball-milling potash feldspar, spodumene, silica micropowder, water and the like, the castable body is composed of alumina homogenized material particles, flint clay particles and the like, the castable is poured into a ladle lid steel structure, the surface of the castable is coated with the coating, and then the castable is dried and baked at 500-900 ℃ to obtain the ladle lid lining. The lining has the characteristics of good heat insulation performance, high strength, excellent anti-erosion performance and long service life, but the preparation process is complex, a high-temperature oven is particularly needed, the procedure is complex and the cost is high, in addition, the torpedo tank cover adopting the lining also has the problems of large weight, special hoisting setting for installing the tank cover for opening and closing, high investment cost and insufficient field space.
Therefore, most of existing torpedo hot metal mixer car tank covers are complex in structure, complex in processing technology, heavy in weight and inconvenient to use and overhaul, and therefore the problem that the existing torpedo hot metal mixer car tank covers are required to be solved urgently by reducing heat loss and raising dust is solved by developing a novel detachable tank cover which is simple in structure, light in weight, easy to install and overhaul and low in investment cost.
