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 now be further described through embodiments and in conjunction with the drawings.

[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 the cutting torch with a trace amount of gas and a very small amount of gas needed to maintain the soybean oil lamp type long open flame when the cutting gas is cut off. Of high-pressure oxygen. This method is realized by automatic control system control.

[0017] The ignition device of the present invention is shown in the figure. The gas supply pipe 2 and the high pressure oxygen supply pipe 3 of the cutting gun 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 cutting gun. . The gas solenoid valve 4 and the high pressure oxygen solenoid valve 5 are respectively connected to the PLC programmable controller 6 through signal lines, and the PLC pr...

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 steelmaking continuous casting cutting device, in particular to a cutting gun point method for steelmaking continuous casting cutting and an ignition device thereof. Background technique [0002] In steelmaking and continuous casting production, the cutting speed and reliability of cutting tools are an extremely important factor that restricts steelmaking and continuous casting production. Therefore, the cutting device is required to have a higher continuous casting cutting speed to meet the increasing billet drawing 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 tool, the overall composition and use of the cutting tool, the cutting process, and the ignition method and device of the cutting tool. For the ignition of cutting tools, the existing cutting tools generally use artificial ignition. This method ha...
