Refractory Ceramic Filter is distinguished by the complexity of the processes and using various equipment and mechanisms. Particular attention is paid to ceramic filters in the foundry, which are used to clean molten metal from slags and various impurities. Used for cleaning such metals
They are made of titanium carbide or ceramic oxide. Refractory Ceramic Filter makes different sizes and diameters. The service life depends on the conditions in which they were used. The presence of filters allows you to constantly monitor the quality of casting and reduce the amount of marriage.
Periodically, they need to be changed after examination by specialists. Not all filters are equally effective. You need to choose products from well-known manufacturers that have been tested and have a quality certificate.
Refractory Ceramic Filter Benefits
The quality of the metal depends not only on the equipment, but also on the filters that are used in the workshops. They have many advantages:
– high thermal conductivity;
– strength;
– resistance to temperature changes;
– low price.
High characteristics allow using them even in cases when metal casting is carried out directly on the filter. This method allows you to completely eliminate the ingress of any impurities into the molten metal.
Filters are distinguished by their porosity, size and ability to clean. Some models are also used to remove oxygen from the cast. The presence of various non-metallic inclusions leads to the appearance of gas shells and porosity.
These defects significantly reduce the quality of the metal. They are formed during the mixing of slag and metal during melting. May also appear during pouring into molds. The use of ceramic filters in foundry significantly reduces the number of defects and defects.
Refractory Ceramic Filter Cleaning
High-quality metal must always meet GOST standards. The easiest and most affordable way to clean it is to use ceramic filters. All slags and non-metallic inclusions during cleaning are delayed on the internal channels of the filter and do not enter the metal. This feature makes them popular in any foundry.
Non-metallic additives are also delayed to some extent by filters. In addition, cleaning takes place as a result of rarefaction of molten metal that has already passed through the filter.
During this process, various impurities float to the surface and fall into the slag trap. Quality filters are used today in all foundries.
