Manufacturing of Porous Steel - Essay Example

The new industrial methodology for manufacturing and producing Porous Steel is a relatively new invention and was patented only recently in 2006-2007 through its Korean inventors Rin-soon, Yongsang, Wonjong-dong, Ojeong-gu, and Bucheon. (WO/2007/018403) Porous steel is a special type of steel which requires a method of manufacturing steel through special preparation of the metallic bodies with plural cores which are coated and then rearranging them in contact with each other in a certain position which allows the pores to be formed there between, and thus the arranged metal bodies are heated to be point welded.

(WO/2007/018403) The above mentioned Porous methodology allows the pores formed in the porous special steel to be flexible enough to be able to change according to the size of the metallic bodies. This further allows other special steels to be manufactured with ease and flexibility according to the kind of cores and coating metals. (WO/2007/018403) Porous Steel manufacture relates to a method of manufacturing the special steel in diverse shapes and sizes due to its flexible pores. This is a novel invention in a time of heavy industrial development whereas the improvement in life environment necessitates an increasing need in the Steel industry for flexible raw materials.

Porous steel is different from the traditional metallic steel products in the sense that they are found in powdery or other solid forms but the porous special steel with its flexible shapes and sizes has appeared in the various industrial uses and works better than ordinary steel by securing sufficient pores therein. This property of the metal allows to also serve a filtration purpose which having a function of filtering particles contained in gas or liquid can then be utilized as a highly efficient heat resistant material due to its qualities of excellent air permeability and conduciveness to heat.

There is however a problem which can technically hinder the use of the porous steel. The conventional method of making Porous steel consists of a number of steps for example it will include the salts to be welded to each other and placed in a press die ,where as the raw metal will have lower fusion points. (Lee et al 2007)However the problem is that not only does this require a heavy use of equipment (like the use of magnanimous press dies in order to permeate the salts and metal into the raw metal) but the welding process can prove to be a nuisance in itself.

(Lee et al 2007)However the inventors have also presented a new methodology to get around these complications with ease by the arrangement of metallic bodies in which a plurality of cores thereof is coated with metal. Such a method warrants better achievement of the dexterous task of manufacturing porous special steel, which is capable of manufacturing even complex-shaped special steel with ease. This will involve the coating of the cores of the metallic bodies with ferromagnetic metal. Then these metallic bodies will be magnetized to allow the arrangement to build a magnetic force between the metallic bodies.

(Molin et al 2008). The method allows for the provision of easily manufacturing special steel alloys based on various cores and coated metals which are then capable of changing the
