Description
Technical field
It is existing using workshop the present invention relates to the exploitation of a kind of molten iron ladle pouring process based on the remaining steel line of return and device
Steel of having a surplus returns to car as the carrier of hot-metal bottle used in molten iron line, realizes the online tank switching of hot-metal bottle, belongs to process for making field.
Background technology
The foundation of molten iron ladle pouring facility is based primarily upon following two factors：
The mismatch problem of blast-melted use tank and steely iron water pot；
Workshop uses " a tank system " hot metal supply, solves the problems, such as hot-metal bottle and tank.
Molten iron ladle pouring facility is routinely arranged in workshop charging across interior, do not only take up charging across usable floor area, but also need
Increase the one-time investment of molten iron weighing chassis, be worth steel mill to be thought deeply in terms of reduction one-time investment and operating cost.It is remaining
Steel returns to car as remaining steel and returns to special-purpose vehicle, and utilization rate is very low, improves work of the utilization rate to steelshop that remaining steel returns to car
Skill direct motion and equipment control are highly beneficial.
Molten iron ladle pouring station is the necessary links in large-scale steel mill's production, for receiving the fish torpedo ladle molten iron in ironworks, and is poured into
Hot-metal bottle, after weighing, pours into pneumatic steelmaking.Molten iron weighing result is the important number needed for automation of converter steelmaking model is calculated
According to directly influencing the control accuracy and STEELMAKING PRODUCTION rate steel-making cost of automatic Steelmaking system.In traditional steel making operation,
Above-mentioned weight of molten iron data are generally gathered using manual method, because influence factor is more so there is error, directly influenced
The control accuracy of automatic Steelmaking.Therefore, ladle pouring station molten iron on-line weighing is realized, there is important meaning for pneumatic steelmaking production
Justice.
The innovation and creation returning to car using remaining steel carries out the online tank switching of hot-metal bottle, not only reduces equipment and disposably throws
Money, also improves the utilization rate of equipment and installations that Yu Gang returns to car, increases charging across the space of technological operation.
The content of the invention
In view of the above-mentioned problems, the present invention provides a kind of molten iron ladle pouring system based on the remaining steel line of return, including：It is arranged in parallel
