Honeycomb Ceramic Use For Foundry Industry(Φ90、Φ60、Φ52、Φ50)


Description

Ceramic honeycomb filters are widely used in metallurgy, metal melt filtration of the foundry industry, mullite (cordierite), ceramic materials, high-quality high-density straight hole mesh, so that the product has a high thermal shock resistance and high temperature the characteristics of straight-hole design to ensure the balance between the flow and the strength to remove impurities and slag particles, so that the mechanical properties of castings and greatly improve the surface quality and rate of qualified products.

Honeycomb Ceramic

Material

Can be Mullite, cordierite, alumina, silicon carbide.

 

Features

Honeycomb ceramic materials with the natural ability of chemical adsorption (affinity) oxides, and adsorption on the inner wall of the hole in the liquid metal impurities (particles smaller than the hole size) to improve the filtering effect; advanced extrusion production has a unique square and triangle design process, so that ceramic filters, it increases the contact area with ceramic filters adsorption and the ability to capture small impurities than the non-extruded filters filter good effect, stable liquid metal; casting speed and continuity, reduce casting scrap rate and improve the mechanical properties of castings and prolong life.

 

The main advantage of the product are:

(1) Have a very high high-temperature strength, thermal shock resistance and resistance to metal flow impact the ability. No dregs or rupture phenomenon at work to ensure the quality of the filtration of molten metal.

(2) The ability to mechanical shock. No broken or damaged in use and transport, will greatly facilitate the use of filters of the operation.

(3) Has a very significant filtering effect. Is much higher than the filtering effect of the fiber filter. Significant filtering effect.

(4) Can effectively reduce the turbulence of the liquid metal pouring, filling gentle, to avoid casting surface defects.

(5) Metal flow rate, and the flow rate stability (as distinct from the flow rate of the ceramic foam filters with to capture the increase in the number of inclusions decreased). Even if mixed with the matter content in the molten metal, the normal use will not cause the clogging of filters.

(6) With high chemical stability, not affected by the pH of the liquid metal does not change the chemical composition of the liquid metal.

(7) Have a very high dimensional accuracy, and can be used to automatically place in the production line of filters.

(8) Clearly superior to the use of performance cellular ceramic filters fiber filters, fiber filters in the filter effect, reduce the role of the turbulent flow of liquid metal, ceramic filters are not as good as high-temperature strength and other properties. The ceramic filter is the filter casting manufacturers in terms of practicality, reliability, quality and price considerations, chosen to eliminate the defects in the casting.
