Hot Extruded Steel Shapes
Since 1941, the first successful of making steel shapes with hot extrusion using glass lubricants in France, the number of applications for hot extrusion steel shapes has shown remarkable growth in such fields as structural members and machine parts.
NIPPON STEEL installed the hot extrusion plant at its Hikari Works in 1960. Based on the many years of research and development, we have established a sophisticated hot extrusion production system with high-quality steel shapes. Currently, these shapes are highly evaluated by our customers.
Features
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 configurations. The hot extruded shapes thus obtained are then subjected to tensile straightening and other finishing processes to produce the final product.
Accordingly, the hot extrusion process is suitable for producing shapes of complex configuration, multiple-grade / small-lot shapes, and difficult-to-process materials.
Freedom of Design
In contrast to standard specified 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.
Save the Machining Process
In contrast to the conventional method by machining (lathe, milling) from material block, the hot extrusion process forms shapes by passing the material through die calibers, thereby greatly saving the machining process.
Save the Welding Process
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.
Suitable for Small-lot Production and Model Changes of Shapes
The cost of hot extrusion tools is much lower than that of rolling mill tools (rolls): Accordingly, the hot extrusion process allows not only the minor dimensions 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.
