Compared with fuel oil, gas or natural gas smelting furnaces have a low cost, consume about 250 kilograms of coal per ton of aluminum, and reduce the burning loss by 40%. Automatic alarm for gas leakage.

No crucible pool furnace, long life, no iron hyperplasia. According to needs, the discharging method can be scooping or plug type. Optional PID control system. A full set of gas-containing furnace and melting furnace, electrical control. The gas generator is the first miniaturization of the gas generator of our company, which is suitable for the melting of the pool furnace. Technical parameters of gas natural gas aluminum furnace

★ Compared with fuel oil, coal gas has low cost, about 200 kilograms of coal per ton of aluminum, and low cost of use: 2.5Kg coal is equivalent to 1Kg diesel. ★ Burning loss decreased by 40%. Long life, no iron hyperplasia. ★ Automatic feeding and small footprint. ★ According to the need, the discharging method can be scoop or plug type. ★ PLD control system. Fuel can also use city gas or diesel, the price of which is negotiable.

Editing of safe operation rules of gas melting furnace

1. Before work, the crucible must be checked for cracks. Before the crucible is used (the metal crucible must be carefully painted), it must be preheated to above 600 ℃ and fully dried.

2. There must be no water around the stove and in the pit in front of the stove, and no unrelated items should be stacked.

3. The charge shall be inspected, and its variety, specifications and block size shall comply with the regulations. Strictly inspect the furnace charge for explosives. Adding the furnace charge must be preheated and dry, and the addition speed should be slow.

4. The tools used for sampling, melting and pouring must be preheated before use.

5. Pay attention to air circulation, and the ventilation and exhaust devices should be normal and good.

6. During deterioration and refining, the operator must wear a protective mask and stand in the upwind position to operate.

7. When pouring is completed, the crucible should be straightened first, and the crucible should be clamped out of the furnace after holding the tongs.

8. When pouring metal liquid from the crucible to the small ladle, do not overfill it, and put some sand on the bottom of the small bag to prevent the liquid metal from splashing and causing burns.

9. Do not sprinkle water on the furnace wall. The bottom of the furnace (for solid fuel furnaces) is not allowed to sprinkle water.

10. Matters needing attention when using solid fuel furnace heating crucible to melt metal:

(1) Before operation, check whether there is water accumulation in the blower placement pit, check whether the pipeline part is good, whether the furnace bar is evenly arranged, safe and reliable;

(2) The coke of the first furnace must be packed tightly to prevent the crucible from toppling over. The refractory bricks with crucible must ensure that the crucible is stable;

(3) When adding coke, add high-quality coke around the crucible and plug tightly;

(4) When observing the melting situation during the smelting process, the blast must be stopped. When observing, pay attention to keep a certain distance from the flame;

(5) When pouring, after the crucible is taken out of the furnace, immediately cover the furnace.

11. Precautions when using an oil furnace to heat the crucible to melt the metal:

(1) Before use, check whether the gas and oil circuits are normal;

(2) Ignition operation in accordance with the safe operation rules of the oil furnace division: first close the air outlet, slightly open the throttle, use the ignition rod to ignite the burner, then open the throttle and adjust it, and prohibit the pressure of oil. Pay attention to adjusting oil and valves to make them fully burned;

(3) When opening the furnace, the ventilation equipment must be opened to remove smoke;

(4) If it is a rotatable oil furnace, it must be adjusted in the melting process;

(5) The oil tank must be placed at a certain distance from the melting furnace to avoid fire.

12. Matters needing attention when melting crucible with gas fuel:

(1) First check whether each switch position is normal. Open the furnace door and flue gate to allow air circulation. Check the pressure gauge before lighting the furnace to determine whether the gas is sufficient. When necessary, contact the person on duty at the gas station to prevent an explosion during ignition;

(2) Before ignition, close the air valve, ignite the ignition rod, and then slightly open the gas valve, point the burner, and then adjust the air and gas flow; the sequence is reversed when the furnace is stopped, and it must not be disordered. Pay attention to adjusting the ratio of gas and air at any time, so that the flame is bright and there is no explosion. If tempering or other abnormal phenomena are found, the furnace should be stopped immediately for maintenance. If the temperature of the burner is too high, it can be cooled by spraying water after the furnace is stopped, or it can be used after blowing for 15 minutes to prevent tempering;

(3) No open flames are allowed near the gas pipeline and burner. If gas leakage is found, immediately notify the gas station and relevant personnel for repair, and it is strictly prohibited to use it before repair;

(4) After the work is completed, clean the work site, check the gas pipelines and valves for leaks, and leave the site after everything is done properly.

13. Matters needing attention when melting by resistance furnace:

(1) Before starting the furnace, check whether the electrical equipment, furnace body and other auxiliary equipment are normal and reliable;

(2) Frequently remove the rust on the outer shell of the iron crucible to prevent the scale from falling off and make the crucible and heating wire "bridge" or "short circuit";

(3) It is strictly prohibited to quench the heating wire;

(4) The distance between the outer wall of the crucible and the hook brick should generally not be less than 60 mm; to avoid accidents caused by the "drum" of the crucible.
