Direct connection type process for iron making and steel making interface

Abstract

The invention discloses a direction connection type process for an iron making and steel making interface, and belongs to the technical field of iron and steel procedure interfaces in metallurgy. According to the direct connection type process, a blast furnace iron making workshop, a molten iron conveying line, a molten iron jar conveying cart, a crane, a molten iron jar baking device, a converter steel making workshop and a pig casting machine workshop are involved. The blast furnace iron making workshop and the converter steel making workshop are directly connected through the molten iron conveying line, molten iron is received under a blast furnace and then is directly conveyed to the steel making workshop through the molten iron jar conveying cart on the molten iron conveying line, and the distance between the iron making workshop and the steel making workshop is shortened to the maximum extent; the traditional organization pattern that molten iron is conveyed through a huge railway system is changed, the molten iron conveying procedure comprising the multiples links of transition crossing, transferring crossing, buffering crossing and the like adopted by an iron making-steel making 'one jar to the end' interface is improved, and the molten iron conveying links are reduced; rapid and efficient molten iron conveying is achieved to the maximum extent, and the general layout is compact and orderly. By means of the process, the environmental benefits of reducing temperature decreasing of the molten iron, reducing iron losses, lowering energy consumption, reducing occupied space of projects, reducing the soot emission range and lowering soot pollution are achieved.

Description

technical field [0001] The invention belongs to the technical field of metallurgical iron and steel process interface, and in particular relates to a direct-connected ironmaking-steelmaking interface process. Background technique [0002] In the past ten years, with the rapid development of metallurgical technology, the interface technology has attracted more and more attention from the metallurgical industry. The "one tank to the bottom" molten iron transportation process between the ironmaking-steelmaking interface has gradually replaced the traditional torpedo tanker for the canning operation. With the maturity of the "one tank to the bottom" production process between the ironmaking and steelmaking process interfaces, its superiority is becoming more and more obvious in the production of steel plants. Its technology will undertake, transport, and buffer the blast furnace molten iron , hot metal pretreatment, converter iron mixing, container rapid turnover and hot metal h...

AI Technical Summary

Problems solved by technology

There are many operation links, such as the transfer span and transition span of the molten iron tank, in order to realize the transfer of the molten iron tank, it is necessary to configure a large-tonnage crane, which correspondingly brings a large load of the factory building, a high headroom, and a large investment
