Abstract
The utility model relates to a continuous casting cutting system in the field of iron and steel metallurgy, in particular to a device for removing flame cut casting blank adhering slag online. The device comprises a flame cutter and a cutting swing arm connected with the flame cutter, the cutting swing arm is connected with the outer wall of a pipeline, and the pipeline is connected with a gas spray-blow device. The device is simple in structure, an existing device is conveniently improved, molten steel slag generated in flame cutting of casting blanks can be simply, effectively removed online, so that the adhering slag below the continuous casting blanks is prevented.
Description
Technical field
The utility model relates to Ferrous Metallurgy field continuous casting diced system, relates in particular to a kind of device of online removal flame cutting strand dross.
Background technology
The cutting of steel industry continuous casting billet extensively adopts the mode of flame cutting, and the liquid state forming in cutting process cutting slag often adheres to and is set in edge under continuous casting billet, forms cutting dross.This phenomenon causes the generation of steel-fastening accident in steel rolling process, and cutting dross can be pressed into stocking surface and makes stocking occur mass defect.In prior art, mode to removal strand cutting dross such as it carry out that machinery impacts, strikes off after taking strand cutting to roll off the production line more, this class slagging-off mode not only needs to be equipped with specially staff and workplace, and cost of investment is high, long and inefficiency expend time in.
Utility model content
In order to overcome prior art deficiency, the utility model provides a kind of device of online removal flame cutting strand dross.The utility model is simple in structure, convenient to existing equipment transformation, and the liquid steel slag producing in the time of can removing online simply and effectively flame cutting strand, prevents the generation of dross.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A device for online removal flame cutting strand dross, comprises flame cutter and connected cutting swing arm, and described cutting swing arm is connected with pipeline outer wall, and pipeline is connected with gas blowing device.
Flame cutter is all arranged in cutting swing arm, along with the movement of cutting swing arm, move, in pipeline, be connected with gases at high pressure, the gas blowing device ejection of gases at high pressure through being connected with pipeline, the position of gas blowing device can regulate, be located at the lower side certain angle of strand cutting seam, like this high pressure draught can by strand by flame cutting after the liquid steel slag of generation blow off, it cannot be bonded in and on strand, solidify formation dross.
Preferably, described pipeline is metal tube.
Pipeline is made as metal tube, and heat-resisting quantity is stronger, is wherein metal hard tube with the pipeline of gas blowing device connection, and pipeline more than cutting swing arm is metal hose.The position of metal hard tube and form are convenient to be regulated and fixes, and the gas blowing device that its end is connected is positioned at the lower side certain angle in strand cutting gap, can by high pressure draught, strand be blown off by the rear liquid steel slag producing of flame cutting in time; The length of metal hose can regulate, and can not hinder the motion of cutting swing arm.
Preferably, described gas blowing device is gases at high pressure nozzle.
Preferably, on described pipeline, be provided with successively from left to right ball valve and magnetic valve.
During overhaul of the equipments, can control pipeline inner high voltage gas by ball valve and close completely, alleviate potential safety hazard.Magnetic valve is used for realizing the ventilation of pipeline inner high voltage gas and the conversion of closed two states.
Preferably, described device also comprises PLC control system, and the output of PLC control system is connected with the input of magnetic valve.
PLC control system is controlled the open and close state of magnetic valve, has alleviated staff's workload, has improved operating efficiency.
Preferably, on described pipeline, be also provided with gas voltage stabilizer.
Preferably, described gas voltage stabilizer is between ball valve and magnetic valve.
Gas voltage stabilizer has improved the security of device, has also stablized the air pressure of gases at high pressure simultaneously, has improved operating efficiency.
Compared with prior art, tool has the following advantages the utility model:
1, simple in structure, O&M is convenient, cost is low;
2, the utility model has changed traditional strand and rolls off the production line and remove the mode of cutting dross, realized with strand cutting and synchronizeed, removed online strand cutting dross, remove the gred effective, operating efficiency is high, has reduced and has removed required human and material resources and the space hold of strand cutting dross.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, flame cutter 7 is connected with cutting swing arm 6, and gases at high pressure nozzle 8 is connected with pipeline 2, and the outer wall of pipeline 2 is connected with cutting swing arm 6.
On pipeline 2, be also provided with successively from left to right ball valve 3, gas voltage stabilizer 4 and magnetic valve 5, the output of the input PLC control system 1 of magnetic valve 5 connects.
During the utility model work, according to the environment of working site, by twisting pipeline 2, make the gases at high pressure nozzle 8 of its connection be positioned at strand cutting seam side-lower certain angle.
Gases at high pressure nozzle 8 and flame cutter 7 move along with the movement of cutting swing arm 6, PLC control system 1 is controlled magnetic valve 5 and is opened, in pipeline 2, be connected with gases at high pressure, gases at high pressure are through 8 ejections of gases at high pressure nozzle, the iron liquid that high pressure draught produces strand after by flame cutter 7 cutting blows off, it cannot be bonded in and on strand, be frozen into dross.
