Embodiment Construction

[0021] Figure 1 ~ Figure 3 It is a specific embodiment of the present invention.

[0022] The molten iron tank combination cover is composed of a positioning ring 1, a molten iron tank cover 2, a suspension ring 3, a hinge 4, an iron receiving nozzle cover 5 and a swing ring 6. The molten iron tank cover 2 and the iron receiving nozzle cover 5 are connected by a hinge 4. The entire combined cover Position by positioning ring 1 and the fixed pin on the ladle. The contact surface of the combined cover of the molten iron tank and the mouth of the molten iron tank realizes its function of heat insulation and heat preservation through refractory materials, and the refractory joint surface of the molten iron tank cover 2 and the molten iron tank cover 5 is automatically aligned and sealed.

[0023] The present invention can ensure that the lid 2 of the molten iron tank with the molten iron tank is ironed, and the full tank is transported by the random vehicle or the empty tank is ...

Abstract

The invention relates to a hot-metal bottle combined cover and a cover adding and uncovering method thereof, and belongs to the technical field of hot metal transportation. The hot-metal bottle combined cover consists of a positioning ring (1), a hot-metal bottle cover (2), a suspension ring (3), a hinge (4), a hot metal receiving opening cover (5) and a swinging shifting ring (6), wherein the hot-metal bottle cover (2) is connected with the hot metal receiving opening cover (5) through the hinge (4); and the whole combined cover is positioned on a fixed pin shaft on a hot-metal bottle through the positioning ring (1). The adding and uncovering method for the hot metal receiving opening cover (5) of a casting house is to arrange a special mechanism in a hot metal outlet opening position of the casting house to complete cover adding and uncovering operations; and the adding and uncovering method for the hot-metal bottle cover (2) of the casting house is to realize cover adding and uncovering operations by a special hanger and a gantry trolley (15). The cover adding and uncovering method has the advantages that a hot-metal bottle is provided with the cover for shielding during transmission and shelving, so that the cover adding and uncovering method greatly saves energy resources, reduces consumption of resistant materials and a heat-insulated covering agent and environmental pollution, prolongs the service life of the resistant materials of the hot-metal bottle, and obviously reduces the turnover number of the hot-metal bottle.

Description

technical field [0001] The invention belongs to the technical field of molten iron transportation, and in particular provides a combined lid for a molten iron tank and a method for adding and removing the lid. Background technique [0002] Oxygen converter steelmaking is a steelmaking method based on blast furnace molten iron as the main raw material. Hot metal is the main source of iron in the steelmaking process, accounting for more than 80% of all steel materials. The physical heat brought in by the temperature of molten iron accounts for more than 50% of all heat sources in the steelmaking process. The higher the temperature of molten iron, the more iron-containing coolants such as steel scrap and iron ore can be used in the steelmaking process, and the steelmaking cost can be reduced accordingly. [0003] There are mainly two types of containers for transporting blast furnace molten iron to the converter workshop in modern converter steelmaking plants: torpedo-type mo...
