What is high quality plasticine clay?
Refractory clay – This is a variety of refractory material, used to seal the tap hole. There are two types of water furnace slurry and anhydrous blast furnace slurry - for large and medium blast furnaces with high upper pressure and intensive smelting..
Applying plasticine clay
- Close the iron neck
- Protect the hearth
- Protect the furnace lining
- Bricks for the walls of the protective channel
What are the quality requirements for clay for tap holes??
Clay for a blast furnace should, Firstly, plug the outlet well, secondly, ensure smooth opening of the outlet channel when tapping, and the outlet channel formed by it should be smoothly tapped, And, thirdly, the outlet must be deep enough, to protect under, if any function is not performed or is not perfect, but this can lead to accidents.
Features of high quality plasticine clay
(1) Possessing good ductility, it can be smoothly pushed into the outlet hole from the drill gun and fill the channel of the outlet hole.
(2) It has fast-drying and fast-hardening properties, hardens in a short period of time and has high strength.
(3) Opening efficiency is good, so that the outlet can open smoothly.
(4) The resistance of cast iron to high-temperature slag formation and erosion is good. In the threading process, the exhaust port hole cannot be enlarged due to high temperature molten iron flushing, to ensure a stable flow of molten iron.
(5) Volume stability is good, and it has a certain porosity, which guarantees, that after blocking the outlet channel, excessive shrinkage and destruction will not occur during the heating process, and the appropriate porosity allows the volatile components in the gun clay to escape smoothly, no cracks, ensuring sealing of the iron neck.
(6) No pollution, creating good working conditions in front of the furnace.
