industrial electric furnace quenching furnace technology operation eleven taboos

1) when the quenching furnace is installed, the workpiece shall not be directly thrown into the furnace, so as not to damage the workpiece or damage the equipment.

2) When the quenching furnace quenches the workpiece, the workpiece shall not contain water, oil and other dirt.

3) There shall be no oil in the quenching water. Soap liquid and other stolen goods shall not be washed in quenching water.

4) The water temperature does not exceed 40C, the oil temperature does not exceed 80C, and the oil temperature is too high, which can easily cause a fire.

5) Do not use compressed air to stir the quenching medium, so as not to attach the air to the surface of the workpiece and affect the cooling speed.

6) strictly wet or water workpieces are heated in a salt bath furnace and must be dried, otherwise explosion may occur.

7) During graded quenching, the alkali bath or nitrate bath shall not be splashed to avoid injury.

8) It is strictly forbidden to immerse the workpiece and tooling adhered to nitrate salt into the salt furnace for heating.

9) It is strictly forbidden to mix combustible substances such as charcoal, oil and organic impurities into the nitrate furnace, otherwise it may cause explosion.

10) The use temperature of nitrate salt shall not exceed the maximum temperature allowed (generally 550C) to avoid fire and explosion.

11) Add water to the nitrate salt bath or alkali bath, preferably at room temperature. If it is necessary to add it at a higher temperature, the temperature should not exceed 150C, and it should be poured vertically.
