Anhydrous Tap Hole for Hot Steel Making Large Furnace
Anhydrous tap hole mix
Anhydrous taphole clay is one of plastic refractory. And anhydrous taphole clay is mainly used in hot metal taphole and blocked the taphole of middle and large type blast furnace .
As the anhydrous taphole clay can be opened and filled repeatedly, it can maintain the stability of the iron mouth and ensure the iron quantity and can also protect the hearth to improve the service life of the blast furnace. It is very popular with the ironmaking enterprise. Common material for anhydrous taphole clay are high aluminum, silicon, silicon carbide, carbon etc.
Anhydrous taphole clay produced by Jundao refractory fire bricks factory is used in 300 cubic-3200 cubic blast furnaces without splashing, which can reduce the labor intensity of the workers before the furnace, keep the iron flow stable, resist the erosion of iron flow, and take 40-120 minutes to tap iron. made of refractory aggregate, powder, binder and liquid. It is rolled and formed from the extruder. The water content is not more than 2%, after burning it formed to refractory plastic that specially used for blocking tap hole of blast furnace, supply in service state.
Jundao anhydrous taphole clay can effectively produce slag iron with high iron output, high coefficient, no mud, less smoke, reduce the pollution of the working environment. The tap hole depth is 1.6-3 meters, which can effectively prolong the tapping time and quantity of iron. It can effectively protect hearth, furnace wall and cooling stave, and is easy to open, save drill bit and drill pipe expenses, and keep mud for up to 6 months.
1,Easy to operate and the pass rate is more than 98%
2,Quick hardening,good property of rapid hardness,high intensity and short time for gun back.
3,Easy to open and one time opening rate can reach more than 98%. Can prevent tap hole crack.
4,The mushroom shape can be formed in the hearth to protect the hearth and wall.
5,Good corrosion resistance,low reaming and long time for tapping
6,Our environmental friendly products can improve the working environment in front of the blast furnace.
