    The fiber web is another unique application in addition to filtering

     At present, the foundry production, casting riser removal process large amount of labor, labor intensity is high, and the lower the degree of mechanization. A lot of riser casting mainly through manual operation such as hammer or abrasive cutting way, high labor intensity, low production efficiency, while the operator faces some threat on safety, health, such as vibration, noise, dust and other environmental. If the special riser equipped with professional cleaning equipment, the cost is not a small investment. For the majority of small and medium-sized castings, by placing a high silica glass fiber mesh sheet in the pouring system, the solidification of metals can be placed in the position after the mesh formed section, can help remove the riser. High silica glass fiber riser easy to cut slices thickness less than 2mm, easy to place, also has the characteristics of high strength, good thermal shock resistance, the mesh can be made into various shapes and sizes according to the actual requirements, in as easy to cut the piece also can play a role in filtering. 

     High silica glass fiber riser easy to cut slices can be placed in various parts of the gating system, such as riser bottom, sprue, runner, especially at the end of the gating system. Easy to cut sheet can create section in position, in the liquid metal solidification because of fiber mesh, through the impact force can strike or shakeout machine vibration makes the smaller section position is disconnected, which makes it easier to remove the riser, reduce costs and improve efficiency.  
     Advantages of using fiber mesh sheet for easy cutting: 

     1, can be hit by removal of riser using a mechanical hammer, significantly reduce the cost of removing the riser 

     2, significantly reduce labor intensity and improve the working environment of removing the riser 

     3, compared with other ceramics, sand, limestone and other refractory riser easy to cut, easy to cut glass fiber sheet with lower cost 

     4, fiberglass mesh piece of high fire resistance, the use of safe and effective, not because of the use of easy to cut off the metal liquid to bring two pollution 

     5, do not change the composition of molten metal fiber net, riser with fiber net can be directly recycled and recycled after remelting, the mesh floating on the liquid metal surface, easy to remove 

     The 6 grid structure, covering the entire section of the separation surface broken more easily smooth, eliminate the "meat" phenomenon, reduce the workload of polishing cleaning riser 

     7, used in large castings, local crack can produce avoid cutting thick root when casting riser 

     Instructions: 

     1, ordinary glass fiber filter can be used for aluminum casting riser easy to cut slices 
     2, high silica glass fiber filter is applied to the riser to cut all kinds of non-ferrous metal, iron and small steel castings 

     3, placed on the bottom of the riser is used, in order not to affect the feeding effect, can open a hole in the center of the mesh 

     4, the use of carbonization treatment of high silica fiber glass fiber easy to cut, heat exchange loss is small, thermal shock performance is better, the use of better 

     5, for large castings in riser, may consider the use of high strength ceramic coating thick high silica glass fiber net used as easy to cut slices
