Problems solved by technology
(1) Large initial investment and high energy consumption of equipment: At present, the approximate price of the deburring machine is about RMB 700,000, the equipment cost is high, and the initial investment is large; in addition, the supporting power of the deburring machine is about 70 kilowatts, and the power consumption is high , such a large power consumption can be regarded as a considerable expense for the meager profits of continuous casting slab production
(2) Large floor area and long production line length: The introduction of deburring machine equipment has greatly increased the total length of the continuous casting production line, followed by a large span of the plant, and a large initial investment in the plant and supporting facilities
(3) The deburring machine occupies a large area, and it is decided that the deburring machine can only be applied to single-flow or two-flow parallel large slabs, while compact multi-flow parallel billets, rectangular billets, Continuous casting lines such as small slabs cannot be adopted at all
(4) The structure and process characteristics of the deburring machine determine that it can do nothing to help the round billet burrs produced by another round billet continuous casting machine with a large market share (because the round billet slag is in a circular arc on a vertical plane Surface) (5) The tool wear of the deburring machine is fast, the maintenance workload is large, and the operating cost is high: the deburring machine is "scraped" by the high-speed rotating flying knife rotary cutting or many arc-shaped cutting knives relying on the forward and reverse movement of the blank Due to the good fusion degree and high fusion strength of the burr, that is, the slag tumor and the billet, the tool wear block is caused, the maintenance workload is large, and the operating cost is high.
On the other hand, continuous casting is continuous casting. In a pouring cycle, the billet is continuously going out. Even if it is found that the tool is worn out and the deburring effect is not good, there is not enough time to stop the machine for replacement and can only make do with it. up! Wait until the pouring is over, and then stop the machine for replacement, so all the personnel on site have the same consensus: the deburring effect of the deburring machine is good when the knife is just replaced, but the good times don't last long, once the knife wears out, the deburring effect discount now

Embodiment Construction
[0020] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0021] The invention is a high-efficiency and energy-saving cutting slag cleaning gun. The high-efficiency and energy-saving cutting slag cleaning gun system consists of a high-efficiency and energy-saving cutting slag cleaning gun, air source control box, PLC control cabinet, on-site operation box, transfer box and related medium pipelines, etc. It belongs to the integration of machine, electricity and gas equipment. The high-efficiency and energy-saving cutting slag cleaning gun consists of a gun body, a nitrogen (or compressed air) pipeline system, a water cooling system, and a slag blowing nozzle. The gun body includes a lock nut (same as 11), a threaded lock joint 3,...

The invention relates to a high-efficient energy-saving cutting slag cleaning gun. The high-efficient energy-saving cutting slag cleaning gun includes a gun body, a nitrogen gas (or compressed air) pipe system, a cooling water system, a specially-produced slag blowing nozzle and a relevant connection and sealing mechanism. The gun body includes a locking nut, a thread locking joint, a stainless steel pipe, a stainless steel bend, an external water inlet joint, and an external water outlet joint, which form a high-efficient energy-saving cutting slag cleaning gun main body; the nitrogen gas (or compressed air) pipe system includes a gas inlet joint, a gas inlet joint base, a thread joint, a stainless steel metal soft pipe, and a gas outlet joint base; the cooling water system includes a central cavity formed by the gun body and the nitrogen gas (or compressed air) pipe system through the relevant sealing mechanism, and a relevant joint; and the specially-produced slag blowing nozzle is formed by that a red copper gasket (heat conduction or sealing) is added between the specially-produced slag blowing nozzle and the gas outlet joint base, which are screwed and connected by the thread locking joint and the locking nut. The high-efficient energy-saving cutting slag cleaning gun is high-efficient, energy-saving, compact in structure, reasonable in layout, perfect in function, is zero in failure rate, and is simple to maintain and clean.
Description
technical field [0001] The invention relates to a cutting slag cleaning device, in particular to a high-efficiency and energy-saving cutting slag cleaning gun. Background technique [0002] At present, the slag nodules (commonly known as hanging slag, also known as burr) formed by flame cutting of billets in the continuous casting production line of steel plants have always been a problem in the steelmaking process, because: the lower part of the billet section and the corners on both sides The slag tumor directly affects the next process-steel rolling. If these slag nodules are not cleared before the slab enters the steel rolling process, it will directly cause the difficulty of the slab entering the rolling mill on the one hand, seriously affecting the rolling process and rolling efficiency. On the other hand, the slag nodules on the cross-section of the billet are crushed by the high-speed rolling rolls when they enter the rolling mill, and a considerable part is ground ...
