Problems solved by technology

For the ignition of cutting tools, the existing cutting tools generally use manual ignition, which has obvious defects; and in order to meet the needs of continuous casting production technology, it is used to avoid affecting casting continuous casting production due to untimely ignition The automatic igniting device of the automatic ignition device adds a little gun without exception, but there is a problem of mutual cooperation between the cutting gun and the ignition gun when using the ignition gun. fire phenomenon or cause an explosion, and this ignition method takes up a lot of space on the production site
Especially for the cutting ignition of the cold billet, because of its technology, structure and other reasons, there is no more reliable, timely and practical ignition method at present.

Embodiment Construction

[0015] The present invention will be further described through embodiment now in conjunction with accompanying drawing.

[0016] The ignition method of the present invention is to set a bypass channel on the gas supply channel of the cutting torch to provide a small amount of gas and a very small amount of gas needed for the torch to maintain a soybean oil lamp type eternal flame for the cutting torch in a non-working state when the cutting gas is cut off. of high pressure oxygen. The method is realized by automatic control system control.

[0017] The ignition device of the present invention is shown in the figure, the gas supply pipeline 2 and the high-pressure oxygen supply pipeline 3 of the torch 1 are respectively connected with a solenoid valve 4 to control the supply of gas or high-pressure oxygen for the cutting work of the torch . The gas solenoid valve 4 and the high-pressure oxygen solenoid valve 5 are respectively connected to the PLC programmable controller 6 th...

Abstract

The invention discloses an ignition method and an ignition device for a cutting gun. The ignition method is simple and easy to implement; and the ignition device is simple and rational in structure and reliable and can ignite timely and save energy. In the method, a bypass channel is arranged on a fuel gas channel of the cutting gun, so that fuel gas needed by intense and bright fire which keeps the mode of a bean oil lamp can be supplied to the cutting gun in a non-working state that cutting gas is cut off. The device comprises a control valve arranged on a fuel gas pipeline of the cutting gun; and a capillary connected in parallel with the control valve is arranged on the fuel gas pipeline of the cutting gun.

Description

technical field [0001] The invention relates to a cutting device for steelmaking and continuous casting, in particular to a pointing method and an ignition device for a cutting torch used for steelmaking and continuous casting cutting. Background technique [0002] In the steelmaking and continuous casting production, the cutting speed and reliability of the cutting tool is an extremely important factor restricting the steelmaking and continuous casting production. Therefore, the cutting device is required to have a higher continuous casting cutting speed to meet the increasing casting The need for speed. The consumption of cutting gas directly affects the efficiency of production and operation, and these are directly related to the quality of the cutting tools used, the overall composition and use method of the cutting tools, the cutting process, the ignition method and device of the cutting tools, etc. For the ignition of the cutting tools, the existing cutting tools gene...
