Using Ceramic Filter for Steel Castings – Process and Benefits

Filtering is an essential step in many industrial manufacturing processes. The prime reason to use this technique is to remove the impurities from the metals used through the manufacturing. Ultimately the quality of the end product improved with the removal of the impurities. The filtering process differs according to the metals and products considered through the manufacturing process. Mainly the filters are used in a corrosive environment and a high temperature applied to it essentially.

Essence of Ceramic Foam Filter:

There are various kinds of filter materials are being available for metal castings. But not all of them have the same temperature and chemical resistance powers. All their efficiencies are evaluated and considered for casting different metals. A high chemical and temperature resistance powered foundry filter will be required for casting steel and other high grade metals.

Mainly the filtration of molten metal throughout the casting process of various components, these ceramic filters become essential. The demand for these products is continuously rising in the international market. The manufacturers are looking for affordable and quality suppliers. The cost of these filters adds to the overall manufacturing cost of the end products. Most of the durable goods available in the market these days are being manufactured with filtered metals.

During the castings, initially, the solid metal is heated using a required level of temperature. Then the melted metal elements poured into a mold or cavity. These molds are created to shape the melted metals into accurate shapes through solidification. Later on, the products connected to the finishing or assembling units.

Die casting is the most common method that uses the ceramic filter for Steel and iron castings. The mold material and pouring method creates variations in the casting processes. Sand, metal or some other kinds of stuffs used as mold materials for manufacturing products. Similarly, vacuum, gravity and low or high pressure pouring methods are the common options chosen for casting.

The ceramic foam filter placed in the gating system leading to the mold. And these filters are really capable to defend against the hit of high temperature molten metal. This filtration process actually improves the quality of the goods created using the filtered metals. It prevents the possible defects like shrinkage voids, trapped inclusions, gas porosity, etc. The durability of the products gets more points through this process.

Not all but many of the ceramic filter for Steel castings used these days are having the efficiency to demise the impacts of reactive elements in the molten metal. Carbon, titanium, aluminum, and hafnium are some common reactive elements found through die castings. Most manufacturers are considering using the foundry filter as it boost yields for the manufacturing goods from aluminum, super alloys, iron alloys, stainless steel and some other kinds of nonferrous alloys.

Filters too help in reducing the scrap rates during the manufacturing process. The manufacturers who are more aware of environment issues, they prefer using these filtration formula. Both foam and cellular filters are being used in many industrial applications these days.

filtec promotions is an expert ceramic engineer and has years of experience in producing foundry filter for various manufacturing industries. He has written several informative articles on ceramic foam filter types. He suggests manufacturers to use ceramic filter for steel for production of quality castings.

Steel foundries looking to order high quality Zirconia ceramic foam filter can opt for the Ca-stabilized Zirconia products made by Filtec Precision Ceramics Corporation. They are in great demand for the filtration of molten steel and its alloys.
