The utility model belongs to structural improvement of ignition devices for cutting machines for cutting steel billets in the production process of a continuous casting machine for continuously casting slabs in a steel plant, and particularly relates to an automatic ignition device for a cutting machine. The automatic ignition device comprises a cutting machine nozzle, a flaming port of a flaming device corresponds to the cutting machine nozzle, an air source is connected with an air inlet of the flaming device through a red copper pipe, an electromagnetic valve is mounted on the red copper pipe, an electronic fire striking device is mounted on a fork pipe connected to the rear of the flaming device and comprises a high-voltage pulse generator, a high-voltage electric control box is connected with the electronic fire striking device through a high-voltage lead, an electrical control box is connected with the high-voltage electric control box through a lead, and the electromagnetic valve is connected with the electrical control box through a lead. When cutting is needed, a cutting gun automatically ignites, fire is automatically extinguished, energy is saved, the operating cost of each ton of steel is reduced, and environmental pollution is decreased.
Description
Technical field
The utility model belongs to the improvement of the conticaster production process cutting steel billet cutting machine ignition device structure of steel mill sheet billet continuous casting, particularly a kind of cutting machine automatic ignition device.
Background technology
In the conticaster production process, cutting machine cuts into certain-length with steel billet, to satisfy the requirement of rolling mill steel rolling.Because cutting machine is at high temperature long-time continuous service, so require it to have high reliability and good maintenanceability.Traditional conticasters etc. all adopt by-pass collar to hold the naked light burning usually when to be cut; Account for the 10%-20% of production cycle clipping time, and the stand-by period accounts for 80%-90%, the naked light burning of a large amount of stand-by period; Promptly caused the significant wastage of combustion gas; Improved ton steel operating cost, flue gas and carbon dioxide that combustion process produces have increased the pollution to environment again, extremely incompatibility modern steel industry energy conservation environmental protection requirement.
Summary of the invention
The purpose of the utility model is to provide a kind of cutting machine automatic ignition device, and in the time of can realizing needing cutting, cutting gun is lighted a fire automatically, cuts the auto extinguishing that finishes, and energy savings, a reduction ton steel operating cost reduce the pollution to environment.
The purpose of the utility model is achieved in that a kind of cutting machine automatic ignition device; Comprise cutting machine nozzle, the bocca of flame device is corresponding with cutting machine nozzle, and source of the gas is connecting the air inlet of flame device through copper tube; Magnetic valve is installed on copper tube; On the back-connected breeches pipe of flame device, the electronic striking device is installed, the electronic striking device is made up of high-voltage pulse generator, and the high-pressure electric control case is connecting the electronic striking device through high-voltage conducting wires; Electric control box is connecting the high-pressure electric control case through lead, and magnetic valve is connecting electric control box through lead.
Consider the characteristics that steel mill's continuity is produced, utilizing shutdown or repair time to transform does not influence production.The utility model is fixedly mounted on the burning torch original position with igniter; Original equipment is not done change; Only need close the ever-burning flame source of the gas; Open source of the gas and get final product if think the recovery use, in PLC, add R-S time command program or get the electric control box that the individual signal (DC24V power supply) of supplying gas inserts this device, realize the control function with succinct electrical system at the gas electromagnetic valve place.
Burning line is drawn bypass as igniting source of the gas at the scene, is connected to flame device with the DN5 copper tube of random arrangement.
High-pressure electric control case and electric control box are installed and fixed appropriate location at the scene, the high-pressure electric control case is connected with ignition device, will consider during installation that the length of high-voltage line can not exceed 35 meters with high-voltage conducting wires, otherwise the excessive influence sparking of pressure drop effect.
The out-put supply of electric control box inserts the binding post of high voltage control case.
The gas electromagnetic valve DC24V power supply of collection in worksite is inserted electric control box, introduce the AC220V power supply again and get final product.
Open the electric control box QF1 that closes and press testing button SB, light flame device, observe the flame profile and the position of ejection, guarantee that flame arrives the position of burning torch.
The utility model adopts the high-voltage pulse generator priming supply, and ignition voltage is high, and power headroom is big, and the sparking gap can be adjusted in moment between electrode, and the igniting reliability is guaranteed.Monthly consumption is 0.1KWh, and power consumption can be ignored.
Adopt the HTHP ceramic insulation, high temperature does not split, and 25000V does not puncture, and is safe and reliable.
The ignitor material adopts high-melting-point alloy, can realize reliable ignition up to ten thousand times, and the life-span is long.
To the fuel wide accommodation, strong to various adaptability for working condition.
Simplicity of design, quick for installation, do not need to shut down, do not influence production, easy to operate.
When the utility model had realized needing cutting, cutting gun was lighted a fire automatically, and the cutting auto extinguishing that finishes, has reduced a ton steel operating cost at energy savings, has reduced the pollution to environment.
Description of drawings
