Abstract
The invention relates to a heating furnace ignition method, firstly filling nitrogen into a hearth of a heating furnace, then carrying out an explosion test and turning on a gas burner and a gas valve close to an ignition hole to feed gas after the explosion test is qualified; then the high-energy electronic igniter is inserted into the heating furnace, and the button of the igniter is switched to the self-locking function for ignition; after the ignition is successful, the high-energy electronic igniter is turned off and withdrawn. Thereby thoroughly solving the defect of manually igniting the furnace by using the torch, avoiding the explosion accident caused by the gas leakage of the pipeline of the heating furnace, ensuring the personal safety and the equipment safety and reducing the accident rate. The method has the advantages of less investment, quick response, low cost, simplicity and feasibility, and convenience for mastering and operating.
Description
Technical field
The invention belongs to the heating process technical field, relate in particular to a kind of method of igniting again that is used for after the walking beam heating furnace blowing out.
Background technology
At present, the heating furnace that domestic hot-rolled strip production line generally uses still was walking beam heating furnace, and this heating furnace just needed blowing out to carry out a scarfing cinder every 4～6 months, and scarfing cinder needs to put again stove after finishing.Point stove mode in the past all is to take the hand-held torch of operator manually to put stove near delivering to fire hole, exists great potential safety hazard.In case heating furnace pipeline gas leak occurs, run into this naked light, serious gas explosion accident must take place, cause casualties and device damage, what directly influence was produced carries out smoothly, brings irremediable various loss.
Summary of the invention
Purpose of the present invention is exactly at above-mentioned defective, provides a kind of method simple, is convenient to operation, can light a fire smoothly, guarantees the ignition method of the walking beam heating furnace of personnel and device security.
For this reason, the technical solution used in the present invention is:
A kind of heating furnace ignition method adopts high-energy electronic igniter, is undertaken by following step:
1, inflated with nitrogen in the heating furnace burner hearth;
2, carry out explosion test and qualified after, open coal gas burner and gas valve ventilating coal gas near the fire hole position;
3, use high-energy electronic igniter to light a fire, earlier high-energy electronic igniter is stretched in the heating furnace, again the high-energy electronic igniter button is switched to the auto-lock function igniting;
4, after lighting a fire successfully, high-energy electronic igniter is closed and withdrawn from.
Beneficial effect of the present invention is:
Owing to adopt high-energy electronic igniter to carry out a stove, thoroughly solved the drawback of artificial use torch point stove, the explosion accident of avoiding heating furnace pipeline gas leak to take place has guaranteed to put stove personnel's the person and device security, has reduced accident rate.And small investment, instant effect, with low cost, method is simple, is convenient to grasp and operation.
The specific embodiment
Below, in conjunction with the embodiments the present invention is elaborated.
At first be to carry out igniter to select.The present invention uses DHQ series A type high-energy electronic igniter.Its specific performance index is as follows:
The igniter total length is 〉=2.5m, wherein spark lever length 〉=2m;
The igniter button ignition switch has auto-lock function;
Igniting form: high energy electron spark formula;
Discharge energy: 〉=16 joules;
Discharge voltage: A 〉=15000V (high energy);
Supply voltage: 4.5～6VDC;
The igniting life-span: 10000 times;
The continuous discharge time: 12h;
Material: stainless steel;
Lighting-up tuyere diameter: ￠ 22mm;
Igniter weight: 4.5～7.5kg (not comprising battery).
Then, undertaken by following step:
1, after heating furnace blowing out scarfing cinder disposes, connects and open nitrogen pipeline, in burner hearth, charge into nitrogen.
2, after nitrogen charges into to a certain degree, at first carry out explosion test, after the pass the test, open coal gas burner and gas valve, ventilating coal gas in burner hearth near the fire hole position.
3, use DHQ series A type high-energy electronic igniter to light a fire.Earlier igniter is stretched in the heating furnace, again the high-energy electronic igniter button is switched to the auto-lock function igniting.
4, after lighting a fire successfully, high-energy electronic igniter is closed and withdrawn from.
Claims (1)
1. a heating furnace ignition method is characterized in that, is undertaken by following step:
(1), inflated with nitrogen in the heating furnace burner hearth;
(2), carry out explosion test, open coal gas burner and gas valve ventilating coal gas after qualified near the fire hole position;
(3), use high-energy electronic igniter to light a fire, earlier high-energy electronic igniter is stretched in the heating furnace, again the high-energy electronic igniter button is switched to the auto-lock function igniting;
(4), light a fire successfully after, high-energy electronic igniter is closed and is withdrawn from.
