In machinery industry,we need melt metals like aluminum,cooper,iron and steel and cast them into complicated geometric casts.In smelting process,there will be some slag caused by impurities and oxide,which will make holes in the casts.To avoid this problem,people developed various kinds of filtering products used in riser and gating system of molten metals.During the past 14 years,our company follows closely new technology in the world to develop filtering products and realize industrial production.Looking forward to your further inquiry!

        High strength molten black silicon carbide filtering block

    This high strength filtering block is made of silicon carbide in special technic way,which is used for filtering metallic solution.Black molten silicon carbide filtering black stands temperature 1660C.They are filtering block used for filtering impurity when big aluminum water and molten steel casting,the shape are round,square and rectangle,size can be process as per client’s requirement.As per size of filtering hole,it can be divided into 10PPI,20PPI and 30PPI.

There are some samples as follows:

Packing:  carton or pallet as customers' requirement
