Cheap 120 Grit Aluminum Oxide Manufacturers Switzerland

In n-cast method, the vibrator is inserted into the trench material for direct vibration, and the trench material has more moisture(green carborundum); in core mold vibration forming method, the vibrator is installed in the core mold, using the thixotropy of the trench material with low moisture, when vibrating, the material flows and gradually densifies(corundum sand), and after the vibration is stopped, the sea material makes the molding and solidification; add the ditch material and vibrate.

For example, the furnace capacity of No.3 blast furnace is 3223m, and the lining of the tapping ditch is made by pouring method(brown fused alumina). In addition, the former uses 4% ~ 6% of ditch material, while the latter does not use water, and can be used after forming. When the above three methods are used for the construction of the blast furnace tapping ditch, the steps are as follows: remove the residual iron and residue, and purge them(black oxide aluminum); set up the tire mold and add the load, or install the transfer molding machine.

(cheap 120 grit aluminum oxide manufacturers switzerland)The difference between VF method and SVP method is that the structure of core mould is different(brown aluminum oxide). When the cast refractory is used as the village in the iron ditch, it needs to be cured for 1-2h and dried for 7-8h; if the refractory vibrating material is used to construct the lining, it only needs 5.5h and can be used after forming(glass beads supplier), but the dust is too large, so a small amount of liquid oil material needs to be added, the rest are refractory aggregate.

Compared with the ramming construction method(brown aluminium oxide), the construction time is shortened to 1 / 10, the working time is saved by 4 / 5, the quality is good, the service life is increased by about 1 time, and the consumption of refractory materials is reduced by 1 / 3(aluminium oxide 36 grit). The mixture ratio of the castable is 100% of the refractory aggregate, 1% ~ 10% of the resin, 0.5% ~ 3% of the binder, 0.2% ~ 1.0% of the phosphate, and 0.2% ~ 1.0% of the hardener.(cheap 120 grit aluminum oxide manufacturers switzerland)

Compared with the ramming material method, the flow iron of the main iron ditch is increased from 90000 t to 300000 t(1200 grit aluminum oxide), the service life is extended from 40 days to 120 dogs, the unit iron consumption per ton of small ditch material for maintenance is reduced from 0.95kg to 0.65kg, but the baking time needs to be extended for 3 hours(silicon carbide companies), and the SVP method is used for construction in the non iron storage fixed iron discharging ditch village.

(cheap 120 grit aluminum oxide manufacturers switzerland)The proportion of the vibrating material is: 0.1% - 5.0% of aluminum powder covered with resin, 1% - 8% of clay, Metal silicon or alloy silicon 1% ~ 5%(100 grit aluminum oxide media). The lining has not been repaired in the process of use, the amount of molten iron reaches 37000-39001, and the unit consumption of iron refractories per ton is only 0.58kg(fused alumina). Therefore, the ditch lining materials with high strength, good wear resistance and strong oxidation resistance should be selected for these parts.

It should be pointed out that the lining trench material of the main trench of the blast furnace is generally made of the fused alumina silicon carbide system material(80 grit aluminum oxide blasting media), the furnace capacity of No. 4 blast furnace is 4288m, while the lining trench material of the rest parts is made of the pyrophyllite silicon carbide system material(steel grid). Japan Nippon Steel Corporation has used n-cast method and SVP method to construct lining on the blast furnace tap hole since 1978.(cheap 120 grit aluminum oxide manufacturers switzerland)

The service life is significantly improved, and the consumption per ton of iron refractories is reduced to about 0.3KG(silicon carbide price). As we all know, the most easily damaged part of the lining of the blast furnace tap hole is the main tap hole, especially the turbulence area 1 ~ 2m away from the tap hole and the lining at the bottom of the skimmer are damaged more quickly(arc fused alumina). This is due to the mechanical impact and erosion of molten iron and slag under high temperature.
