Hot Extruded Steel Shapes The Tools of Free Design

Since 1941, the �rst successful of making steel shapes with hot extru-sion using glass lubricants in France, the number of applications for hot ex-trusion steel shapes has shown re-markable growth in such �elds as structural members and machine parts.

Nippon Steel & Sumitomo Metal installed the hot extrusion plant at its Hikari Works in 1960. Based on the many years of research and develop-ment, we have established a sophisti-cated hot extrus ion product ion sys tem w i th h igh-qua l i t y s tee l shapes. Currently, these shapes are highly evaluated by our customers.

Hot extruded shapes possess di-verse features that cannot be ob-tained with other production pro-cesses. We strongly recommend these quality shapes to improve ma-chinery performance, reduce pro-cesses, enhance labor savings, and cut costs.

For Solid Shapes For Hollow Shapes

Hot extruded shapes are produced by means of the hot extrusion method. In this method, round billets are heated to around 1,200˚C, and then hot extruded through dies mechanically processed into diverse con-�gurations. The hot extruded shapes thus obtained are then subjected to tensile straightening and other �n-ishing processes to produce the �nal product.

Accordingly, the hot extrusion process is suitable for producing shapes of complex con�guration, multiple-grade / small-lot shapes, and dif�cult-to-process materials.

Merit of Hot Extruded Shapes

In contrast to standard speci�ed shapes by rolling process, hot extruded shapes combine both decorative and structural functions that allow the design of structural members that permit optimal originality and freedom in building design.

Because hot extruded shapes are produced by means of solid forming, the welding processes can be saved. Further, stress relief can be saved, whereby thermal deformation during welding, thereby contributing greatly to cost cutting. In addition, the quality deterioration of weld portion can be prevented and the reliability of end products can be improved.

In contrast to the conventional method by machining (lathe, milling) from material block, the hot extrusion process forms shapes by passing the ma-terial through die calibers, thereby greatly saving the machining process.

Yieldimprovement

The cost of hot extrusion tools is much lower than that of roll-ing mill tools (rolls): Accordingly, the hot ex t rus ion process allows not only the minor di-mensions changes of each product to be altered simply by changing tools, but also the production of small lots starting at one-ton units that otherwise are economically untenable for rolling processes.
