Abstract
The utility model relates to a molten steel refining treatment system, in particular to a molten steel refining treatment system with co-placement of double stations of a CAS (composition adjustments by sealed argon bubbling) refining furnace and an LF (ladle furnace) refining furnace, which is mainly used for solving the technical problems of repeated equipment construction and long production period due to the separate arrangement of the CAN refining furnace and the LF refining furnace. The molten steel refining treatment system adopts the technical scheme as follows: the molten steel refining treatment system with the co-placement of the double stations of the CAS refining furnace and the LF refining furnace comprises the LF refining furnace, a left station molten steel vehicle and a right station steel ladle vehicle are arranged on the left side and the right side of the LF refining furnace respectively, a high-position storage bin is arranged above the LF refining furnace and is provided with a horizontal belt, and a belt blanking point extends to the LF refining furnace through a batching belt and a feeding belt; and the molten steel refining treatment system is characterized in that the CAS refining furnace is arranged on the right side of the LF refining furnace and the feeding belt extends rightwards for extending the blanking point of the feeding belt to the CAS refining furnace. The molten steel refining treatment system is mainly used for refining treatment of molten steel.
Description
Technical field: the utility model relates to the liquid steel refining treatment system, the liquid steel refining treatment system that particularly a kind of CAS refining furnace and LF refining furnace double are put altogether.
Background technology: the CAS refining furnace is by be blown into the rare gas element argon gas from ladle bottom, the top of the slag of molten steel surface is blown open, then by the decline impregnating cover, the molten steel treat surface and the top of the slag are separated, in the inner argon gas positive pressure that keeps of impregnating cover, reduce molten steel nitrogen pick-up, by the reinforced mode that improves a kind of external refining of yield of alloy under the no slag inert gas conditions; The LF stove is a ladle refining furnace, is to be used for regulating liquid steel temperature, replenishes alloy, regulates the control molten steel composition by carrying out BOTTOM ARGON BLOWING, plays the technology buffering, satisfies the important a refining unit of continuous casting, tandem rolling.
The molten steel that existing liquid steel refining adopts RH to handle usually will be walked the LF refining furnace and carry out temperature control, reaches the continuous casting requirement with the temperature drop that guarantees whole refined molten steel.When RH production capacity deficiency, in the time of can not satisfying liquid steel refining, the steel grade that an a little RH handles can pass through the CAS refining treatment, and can effectively control cost.And general CAS refining furnace and LF refining furnace are arranged apart, so just need two cover buggy ladle haulage system, bottom blowing Controlling System, feed silk system, reinforced and Weighing system.Such layout has caused duplicate construction, and technical process prolongs the optimization that is unfavorable for improving production capacity and process for making.
The utility model content: the purpose of this utility model provides the liquid steel refining treatment system that a kind of rationally distributed CAS refining furnace and LF refining furnace double are put altogether, mainly solves the technical problem that equipment construction repeats, the production cycle is long of CAS refining furnace and the existence arranged apart of LF refining furnace.
The technical solution of the utility model is: a kind of CAS refining furnace and LF refining furnace double carry out the treatment system of liquid steel refining jointly, comprise the LF refining furnace, be respectively equipped with left station molten steel car, right working position buggy ladle in LF refining furnace left side and right side, above the LF refining furnace, be provided with high hopper, high hopper is provided with horizontal belt, through proportioning belt and reinforced belt the belt discharging point is extended to the LF refining furnace, it is characterized in that on LF refining furnace right side the CAS refining furnace being set, described reinforced belt extends to the right makes its discharging point extend to the CAS refining furnace.
The beneficial effects of the utility model are: CAS refining furnace and the common layout of LF refining furnace, can use buggy ladle haulage system jointly, and the buggy ladle that thing is arranged all can arrive the CAS refining furnace and LF refining furnace station carries out the molten steel processing.Simultaneously processing unit such as bottom blowing Controlling System, feed a silk system, reinforced and Weighing system is public, also greatly reduce the investment waste that duplicate construction brings.This processing set-up of CAS+LF, just can carry out the alloy fine setting simultaneously at the CAS refining furnace, can select the LF refining furnace to carry out heat treated fast, reduce CAS refining furnace and LF refining furnace and arranged the drawback of the prolongation of the production cycle that brings respectively, the smelting production capacity of bigger raising part refining steel grade shortens the refining treatment cycle.

Embodiment
With reference to Fig. 1, the liquid steel refining treatment system that a kind of CAS refining furnace and LF refining furnace double are put altogether, comprise LF refining furnace 2, be respectively equipped with left station molten steel car 1, right working position buggy ladle 4 in LF refining furnace left side and right side, above the LF refining furnace, be provided with high hopper 8, high hopper is provided with horizontal belt 5, through proportioning belt 6 and reinforced belt 7 the belt discharging point is extended to the LF refining furnace, at the right-hand CAS refining furnace 3 that is provided with of LF refining furnace, described reinforced belt 7 extends to the right makes its discharging point extend to CAS refining furnace 3.On a track, right working position buggy ladle 4 carries out CAS when handling at CAS refining furnace 3 and LF refining furnace 2 molten steel supply lines, and left station molten steel car 1 can carry out the LF refining treatment of other one heat steel water simultaneously.Guarantee also that in control right working position buggy ladle 4 transportation molten steel carry out can also opening to LF refining furnace 2 stations after CAS refining furnace 3 is handled to be proceeded to handle.After station molten steel car 1 transportation molten steel to LF refining furnace 2 stations in a left side are handled, can also continue out to carry out liquid steel refining and handle to CAS refining furnace 3 stations.The molten steel car all is provided with operator's console 9 at LF refining furnace and CAS refining furnace station, and handled easily is observed the situation of ladle and molten steel car.Operation between the operator's console is switched, and can be undertaken by the system selector switch on the operator's console.All can feed in raw material at CAS refining furnace station and LF refining furnace station.The material alloying system share of CAS refining furnace and LF refining furnace is by being arranged in the selection that feeds intake of reversible reinforced belt 7 between the double.
Claims (2)
1. CAS refining furnace and the LF refining furnace double liquid steel refining treatment system of putting altogether, comprise the LF refining furnace, be respectively equipped with left station molten steel car, right working position buggy ladle in LF refining furnace left side and right side, above the LF refining furnace, be provided with high hopper, high hopper is provided with horizontal belt, through proportioning belt and reinforced belt the belt discharging point is extended to the LF refining furnace, it is characterized in that at the right-hand CAS of the setting refining furnace of LF refining furnace described reinforced belt extends makes its discharging point extend to the CAS refining furnace to the right.
