Straight hole honeycomb ceramic filter slice
Used on filter board for metal melting object in metallurgy and casting
The straight hole honeycomb ceramic filter slice is widely used on filter board for metal melting object in metallurgy and casting.It is made from ceramic materials such as mullite (cordierite).The straight hole is of high quality and high density.
It has the following characteristics:excellent anti-hot impact strength,high temperature resistance.The straight hole design ensures the balance between flow and strength.It can get rid of dusts and dregs effectively so that it can greatly ncrease the mechanical performance of castings.surface quality and pass percent of products.

Characteristics:
1The new ceramic material has the characteristic 0f naturaI chemicaI absorbing(Affinity)ability for oxids.It absorbs the dusts in metal liquid(including panicles smaller than the holel onto the inner walI of the hole SO that it increases filtering.
2.The advanced extrusion type production craft makes the ceramic filter slice have the unique square and the triangle design.It increases the contacted area with ceramics and the absorbing and capturing ability of the filter slices for smalI panicles.The metalliquid flows smoothly.
3.1t enhances the casting speed and the continuityreduced the casting waste product rate.It also improves the mechanical performance of castings and prolong its service life
