Abstract
The invention relates to a vehicle-mounted slag-raking machine for a converter, and a use method, and belongs to the field of steelmaking slag-raking technology. The vehicle-mounted slag-raking machine for the converter comprises a slag-raking plate, a walking chassis, a rotary central disk, a telescopic working arm, a cab and a power system, wherein the rotary central disk is arranged above the walking chassis, and the power system is arranged at the left side over the rotary central disk; the cab is arranged at the right side over the rotary central disk, and the power system is adjacent to the cab; and one end of the telescopic working arm is connected onto the power system, and the other end of the telescopic working arm is connected with the slag-raking plate. The slag-raking is started in 4minutes to 7minutes after the start of converting, and the slag-raking machine is driven to a converter mouth, and is rightly opposite to the converter; and in a deslagging process, the slag-raking plate is fed into the converter by the telescopic working arm to slag off. The vehicle-mounted slag-raking machine for the converter has the advantages that: the use is flexible and convenient, and one slag-raking machine can be used for multiple converters; most of converter slag can be fast and effectively racked out, the decarburization slag basicity can be effectively improved by raking out a large number of dephosphorization slag, the dephosphorization efficiency can be improved, the lime consumption of the converter can be reduced, and the consumption of iron and steel materials can be reduced.
Description
Technical field
The invention belongs to the steel-making technical field of skimming, particularly a kind of coverter pig vehicular slag removal machine and method of use.
Background technology
Along with the development and the market keen competition of metallurgical technology, reduce the converter smelting cost, improve a kind of means that the converter smelting steel quality becomes raising steel mill competitive power.
The refinement gradually of domestic in recent years converter smelting process, by single single slag, two slag melting gradually refinement develop into single slag, two slag, duplex, multi-functional steelmaking process etc.Generally be divided into dephosphorization phase, carbon period for two slags and multi-functional steelmaking process; Need pour out slag---dephosphorized slag after the dephosphorization phase finishes, the principal feature of dephosphorized slag be in the slag in high, the slag of phosphorus content sio2 content high, remove dephosphorized slag in a large number and help reducing phosphorus content in the stove; Can also improve the carbon period basicity of slag; Improve dephosphorization effect, require general steel grade, can reduce lime consumption and reduce iron and steel stock consumption for phosphorus content.
Usually the dephosphorization phase deslagging method that finishes to adopt is to carry out deslagging through falling stove after the converter dephosphorization phase finishing blowing; Can remove nearly slag of about 30%～40% through deslagging; After but the deslagging amount reaches certain proportion; Slag in the stove can not continue to pour out, if continue deslagging then occur pouring out the phenomenon of molten iron easily.In order further to reduce the dephosphorized slag in the stove, developed the coverter pig slag removal machine, purpose is on the basis of converter deslagging, to continue to improve the deslagging effect, skims through machinery, prevents that molten iron is poured out in the stove.
Common slag removal machine is desulfurizing iron station slag removal machine and ladle slag removal machine; And slag removal machine is fixed; The corresponding metallurgical tank of slag removal machine; The slag removal machine of mentioning among the present invention is a machine vehicular slag removal machine, can go at the converter platform, can use a slag removal machine jointly for a plurality of converters.
Summary of the invention
The object of the present invention is to provide a kind of coverter pig vehicular slag removal machine and method of use.Remove the slag in double slag process or the multi-functional steelmaking process converting process.
Coverter pig vehicular slag removal machine of the present invention comprises takes off slag plate, walking chassis, revolution mid-game, flexible working arm, wheel house, power system.The revolution mid-game is above the walking chassis, and power system is the left side directly over the revolution mid-game, and wheel house is the right side directly over the revolution mid-game, and power system and wheel house are adjacent; Flexible working arm one end is connected on the power system, and an other end connects takes off slag plate.The material of taking off slag plate is a high temperature resistant steel plate, and width is 0.3m～0.8m, highly is 0.3m～0.7m, and thickness is 5cm～15cm.
Coverter pig vehicular slag removal machine of the present invention is the vehicular equipment of skimming, and locomotive can go at the converter platform, and the object of skimming is a slag in the converter stove.
Concrete process step is following:
1, bessemerizes the beginning back and begin the grate slagging-off in the time of 4～7 minutes;
2, treat that converter slagging-off proceeds to converter and is horizontal back vehicular slag removal machine and goes to converter mouth, flexible working arm is over against converter;
3, open the retaining vent, use flexible working arm will take off slag plate and send in the converter stove and skim;
4, when near the molten steel converter mouth occurs 5%～15% bright, finish to skim.
The invention has the advantages that:
1) flexible and convenient to use, a slag removal machine can be to many converters;
2) effectively remove most of converter slag fast;
3) can effectively improve decarbonized slag basicity through removing a large amount of dephosphorized slags, improve dephosphorization efficient, reduce the consumption of converter lime, reduce iron and steel stock consumption.
