Application of analytical iron bars
Application of analytical iron bars
The horizontal continuous casting process can be obtained relatively dense matrix structure,the level of continuous casting profiles Hydraulic resistance and air tightness were higher than other engineering materials,we can say,with a horizontal continuous casting sections of steel production is by far the best hydraulic material.In addition to its high-yield,low production cost,there are significantly superior than steel machinability,it is because in the cutting process,the cutting continuous fragmentation,and reducing the cutting resistance.

Characteristics of gray cast iron, classification and application
Characteristics of gray cast iron, classification and application
Common gray cast iron due to the presence of graphite,and graphite tensile strength is almost zero,can be cast as full of cracks or hollow steel.Not only undermine the continuity of the graphite matrix,reducing the load-bearing metal matrix effective cross-sectional area,so that the actual stress is greatly increased;at the same time,the graphite is easy to cause stress concentration at sharp corners,sharp corners of the stress is much larger than the average stress.
