Description
Technical field
The present invention relates to a kind of decoration form of LF ladle refining furnace process system.
Background technology
Along with science and technology development, the progressively raising that the steelworks robotization requires, intelligence steel-making is to become the first-selection of each steel mill, and this just requires each link of steelshop all will improve automatic control level.Along with the continuous requirement of market to senior steel grade, the effect of LF ladle refining furnace in STEELMAKING PRODUCTION is increasing, and the problem that existing LF ladle refining furnace process system exists mainly contains following three aspects:
1) in the layout of existing LF ladle refining furnace process system; Charging system is arranged in that tapping is striden or molten steel receives and to stride; Reinforced adopt artificial batch can feed way, when each material loading, need feed in raw material worker and craneman are through interphone, and reinforced the operation accomplished in artificial communication and coordination; And can't catch processing to the reinforced dust that produces, so such feed way can not satisfy the needs of mammoth conveter STEELMAKING PRODUCTION; This decoration form has determined charging system can not adopt the conveyor feed way simultaneously; Because the iron alloy feed bin height of LF ladle refining furnace is very high; As the overhead traveling crane between adopting that the conveyor mode is reinforced and maybe and striding produces and interferes, and will produce the crane dead band in the conveyor operation area between whole striding, and crane can't carry out any operation in this is regional; Bring very big influence for daily production, cause production efficiency low.
2) decoration form of LF ladle refining furnace process system in the prior art, limited ladle can only one stride between lifting, the crane between so just this being striden requires raising, goes wrong and will impact production in case this strides a crane.
3) dedust air duct of the prior art is located at tapping and strides the top that reception is striden with molten steel; Like this along with the gradually raising of country to environmental requirement; The dedusting air quantity constantly increases, and the dedust air duct section also continues to increase, and dedust air duct has taken the bigger workshop useful space so on the one hand; And the layout that has caused dedust air duct is frequent and the layout generation of production plant processing unit is interfered, and has directly produced influence to producing.
Summary of the invention
The technical problem that the present invention will solve provides a kind of LF ladle refining furnace process system that can realize reinforced robotization control, increase steelshop dispatching flexibility and can significantly improve workman's operating environment.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of LF ladle refining furnace process system; Comprise that the tapping that sets gradually is striden, molten steel receives and strides, ladle car track, charging system and dedusting pipeline; Wherein the dedusting pipeline is located at tapping and strides the top that reception is striden with molten steel; This LF ladle refining furnace process system comprises that also being located at the concise raw material that tapping is striden and molten steel receives between striding strides, and charging system is the conveyor charging system, and charging system is located at concise raw material span centre.
Said ladle car track is provided with two, and between striding across described three.
Said dedusting pipeline is located at concise raw material span centre.
Compared with prior art, technology of the present invention has the following advantages:
1, the present invention can realize the robotization control of reinforced process.The processing set-up mode of LF ladle refining furnace has determined charging system to carry out through conveyor in the prior art; Because the iron alloy feed bin height of LF ladle refining furnace is very high; As adopt the conveyor mode reinforced probably and the overhead traveling crane between striding produce and interfere; And will produce the crane dead band in the conveyor operation area between whole striding, crane can't carry out any operation in this zone, bring very big influence for daily production.The present invention and existing processes arrange to compare have been increased refinery feedstock and has striden between this strides; The charging system of LF ladle refining furnace is arranged in refinery feedstock strides; Can pass through conveyor, blanking bin is directly carried the alloy feed bin of alloy raw material to the LF ladle refining furnace from ground, owing to used the conveyor self-feeding; Improve the automation of operation level greatly, reduced labour intensity.Simultaneously, existing processes is arranged in and requires the LF operative employee to stand on the alloy feed bin service platform when feeding in raw material, and links up through interphone and craneman, accomplishes reinforced.Because the alloy bunker platform is very high; And crane handling batch can carries out the material loading operation above platform; Make craneman's operation sight line receive certain limitation, increased security incident hidden danger simultaneously, the present invention adopts the conveyor material loading then can reduce the security incident hidden danger when feeding in raw material greatly.
2, the present invention can increase the handiness of steelshop scheduling.Existing processes is arranged to receive at molten steel and is stepped into capable ladle lifting operation; And two ladle car track are set among the present invention; And with the track lateral arrangement, promptly track across tapping stride, refinery feedstock is striden and molten steel receive stride three stride between, like this; Accept to stride and tapping is striden two and all can be lifted by crane operation to ladle between striding at molten steel; Arranging to compare with existing processes having increased tapping and has striden this Heave Here, has so just significantly improved the compactedness of producing, and has also increased the handiness that steelshop is dispatched simultaneously.For example: molten steel receives the crane stride for some reason can't be with the ladle on the converter tapping line, when winching on the buggy ladle of LF ladle refining furnace, can utilize crane that tapping strides with ladle, winches on the buggy ladle of LF ladle refining furnace, accomplishes the refining operation of molten steel; Vice versa.Also just because of two ladle car track of LF ladle refining furnace; Stride to receive across tapping and stride with molten steel; Use on ladle handling to the buggy ladle of LF ladle refining furnace on the steel wire this operation many an operating point, reduced molten steel and received the rate of utilization of striding crane, also reduced scheduling problem and waiting time of producing; Improve the compactedness of producing, also increased the handiness of steelshop scheduling simultaneously.
3, the present invention can significantly improve operating environment.Because the present invention has set up refinery feedstock and has striden between this strides, simultaneously with dedust air duct be arranged in this stride between in, avoided the dedust air duct and the interference of workshop processing unit and taking to the workshop useful space; Adopt this to cross simultaneously and stride processing set-up and can effectively solve the Problems of dust in the material loading process, improved workman's operating environment greatly.
