Embodiment Construction

[0022] figure 1 It is a specific embodiment of the present invention. Below in conjunction with accompanying drawing to further explanation:

[0023] The facility of the present invention includes a chemical iron gun mechanism 5, gun body cooling water and gas and oxygen metal hose 3, gun body cooling water and gas and oxygen valve station 8, smoke and dust collection cover 10, dust removal pipeline 11, molten iron tank 12, molten iron The tank transport vehicle 13, the described iron gun mechanism 5 includes an oxygen combustion gun 1, a lifting slideway 2, a lifting trolley 4, and a lifting winch mechanism 7. The process steps are as follows:

[0024] First, use the crane 6 in the workshop to hoist the molten iron tank 12 of sticking iron to the molten iron tank transport vehicle 13 parked on the waiting position for melting iron; then drive the molten iron tank transport vehicle 13 to the melting iron working position. Then, the iron gun 1 is lowered, and the lifting tro...

Abstract

The invention discloses a melting method of bonded iron on a hot-metal ladle and belongs to the technical field of converter steelmaking. A facility comprises an iron melting gun mechanism, a gun-body cooling-water-gas-oxygen metal hose, a gun-body cooling-water-gas-oxygen valve station, a fume trapping cover, a dust removing pipeline, a hot-metal ladle and a hot-metal ladle transporting truck, wherein the hot-metal ladle bonded with iron is lifted onto a hot-metal ladle transporting truck parked at an iron-melting waiting position by using a crane in a workshop; and then the hot-metal ladle transporting truck is driven to an iron-melting working position. Then, an iron-melting gun falls, the lifting trolley falls along a lifting slideway, the iron-melting gun falls into the fume trapping cover and is controlled and ignited by workers in an operation room; according to the iron bonding condition in the hot-metal ladle, the height of the iron-melting gun is adjusted, oxygen and gas of the iron-melting gun are closed after all the bonded iron in the hot-metal ladle is melted, and the hot-metal ladle is taken out of the fume trapping cover; and then the hot-metal ladle transporting truck is driven out, the crane lifts the hot-metal ladle to pour melted iron into a slag ladle, and then the hot-metal ladle is reused. The melting method disclosed by the invention has the advantages of short treatment period, low cost and clean operating environment.

Description

technical field [0001] The invention belongs to the technical field of converter steelmaking, and in particular relates to a method for melting sticky iron in a molten iron tank, which is suitable for melting sticky iron in a molten iron tank for transporting molten iron. Background technique [0002] At present, large and medium-sized iron and steel enterprises in the iron and steel manufacturing industry mainly use the torpedo tank car transportation method and the "one tank to the bottom" transportation method that directly uses molten iron tanks to transport blast furnace molten iron. Torpedo tank car transportation is a relatively mature method of molten iron transportation. After years of development, it has the advantages of flexible maneuverability, good thermal insulation performance, and good stability. There is a gap in the goal of high efficiency and low energy consumption pursued by metallurgical process technology. [0003] The blast furnace-converter interfac...
