How to choose ceramic tea set?

How to choose ceramic tea set? A good ceramic tea set is indispensable for tea drinkers. Today, the editor of ceramic tea sets will show you how to choose ceramic tea sets.

1. How to choose ceramic tea sets

Is the appearance smooth? A good ceramic cup feels mellow. There are no sharp points or uneven places. Take a look when you choose, and you can't rub your hands.

It is resistant to high temperature, so please carefully read the description of the product when choosing. The insulation effect of the ceramic cup is not very good, the temperature is high, the cup is very hot.

Whether the bottom of the cup is flat, some cups work unevenly, the bottom of the cup will be uneven. When choosing, move the cup to see if it can rest smoothly.

Whether the wall of the cup is smooth, and whether the inside of the cup is smooth, without grinding the mouth. You can feel it with your hands to see if it is smooth but still very uneven.

Cup handle design, try to drink water with your hands to see if the cup can be held firmly. The cup handle is also a very important part. It must be able to lift and not slip.

Second, what are the benefits of using ceramic tea

1. Compared with plastic cups, ceramic cups have less harmful gases and substances brought by plastic cups. According to experts, long-term use of plastic cups may cause cancer.

2. The ceramic cup is completely harmless, it will not be like a metal cup, it may ingest harmful metals in long-term use.

3. Due to the existence of the ceramic cup, the molten iron does not directly contact the carbon bricks. The structural design relieves the penetration, erosion and erosion of the molten iron and alkaline substances on the carbon bricks, and the use of mullite, brown corundum, etc. They are all advanced ceramic materials with low thermal conductivity, which have high corrosion resistance and erosion resistance. Eliminate the brittle layer of large carbon bricks.

4. Increase the temperature of molten iron and reduce heat loss: The ceramic cup is made of materials with lower thermal conductivity than carbon bricks and acts as a barrier, thus reducing heat loss through the furnace bottom and hearth. Correspondingly, the molten iron can maintain a higher temperature, which creates good energy-saving conditions for the converter production in the next step.

5. Easy to re-air operation: Due to the thermal insulation of the ceramic cup, the heat loss is reduced during the blast furnace off-air period, which is beneficial to resume normal operation during re-air.

6. Prevent molten iron from leaking: Since the ℃ isotherm, that is, the solidification line of molten iron, is close to the inner surface of the furnace lining, it is migrated to the inside of the furnace. In addition, due to the slightly positive residual expansion of the refractory material, the brick joints are reduced, so the molten iron is Penetration is limited so that the risk of burning through the hearth is minimized.
