Furnace lining manufacturers take you to understand the process of the oven

Today, the furnace lining manufacturer Luoyang Quantong Kiln Industry Co., Ltd. tells you the details of the furnace process:

1. Reminder of gravity furnace lining materials. First, cover the crucible mold with asbestos cloth or furnace cover, leaving only one vent hole, so that the entire furnace lining can be heated evenly, so as to facilitate the overall sintering.

2. It takes 2 hours to slowly heat the furnace to 600 degrees Celsius, keep it here for 1 hour, and then slowly heat the furnace to 1000 degrees Celsius, which takes 2 hours, and keep it here for 1 hour.

3. After the furnace temperature is naturally cooled to room temperature, step on the furnace mold with your feet, gently hit the furnace with a hammer to make it oscillate and have a gap with the furnace wall, and then slowly take out the furnace mold.

4. Check whether the furnace wall has fallen off. If there is a slight drop, it can be repaired by adding glass water and water to the furnace lining material. If there is a serious drop, it means that the furnace wall is not tight enough, and the furnace needs to be rebuilt.

5. Put the iron blocks into the furnace tightly by hand.

6. The furnace must be fully sintered, and the liquid level should reach a position about 100mm away from the furnace mouth, so as to facilitate the overall sintering.

7. The first furnace will slowly heat up and melt the acid lining material, and keep it at 1580 degrees Celsius (±20 degrees Celsius) for half an hour.

When the molten iron temperature is greater than 1500 degrees Celsius, generally monitor the temperature every 10 minutes. Start charging when the initial charge is melted to about 30%. Add until the oven is full.

8. The occurrence of hanging material in the smelting process should be dealt with in time:

a During the smelting process, the material should be added carefully, and the furnace condition should be investigated to avoid the phenomenon of hanging material.

b The temperature of the molten metal in the molten pool under the hanging material is too high, which can cause the furnace lining to be rapidly ablated, and there is a risk of explosion at any time.

c After the material hangs, the power supply should be reduced to 25% of the insulation power to prevent the molten metal from overheating.

d At this moment, the furnace body must be tilted so that the molten metal touches the hanging material and melts a hole.

Roll the furnace body back to the upright position and feed through the holes so that the molten metal touches the hanging material and melts it. Note: Do not overheat the molten metal during this process.
