G2 Gray Iron. DuraBar G2 is a pearlitic gray iron containing Type A graphite. Our continuous cast bars made to this robust specification are a good fit for a variety of applications, due to its good machinability, wear resistance and vibration damping properties.
This paper first reviews the sources of inclusions in continuous casting of steel including both indigenous and exogenous inclusions, focusing on reoxidation, slag entrainment, lining erosion and inclusion agglomeration on linings. Secondly, the resulting defects in continuous cast steel products
The doubleroller mill is fitted with a tamperproof feeding funnel, a safetymonitored collecting box integrated into the base frame and the fullywired control system integrated into the housing. The crusher rollers are available in different materials (cast steel, tungsten carbide and aluminium oxide). Doubleroller mill WS 250x150 L WS ...
Surface preparation is the essential first stage treatment of a steel substrate before the application of any coating, and is generally accepted as being the most important factor affecting the total success of a corrosion protection system.. The performance of a coating is significantly influenced by its ability to adhere properly to the substrate material.

Continuous casting, also known as strand casting, is the process where a metal is heated until it liquefies. The molten metal is then allowed to solidify until it becomes a semifinished slab that is later rolled in the finishing mill. It is used to cast metals of uninterrupted lengths.
Continuous casting, also called strand casting, is the process whereby molten metal is solidified into a "semifinished" billet, bloom, or slab for subsequent rolling in the finishing mills. Prior to the introduction of continuous casting in the 1950s, steel was poured into stationary molds to form ingots. Since then, "continuous casting" has ...

Dec 11, 2014· Defects in Continuous Cast Steels. Continuous casting (CC) is the process which converts liquid steel into a solid product mainly in the form of slab (either thick or thin), bloom or billets. It is one of progressive steel making technologies which produces a cast product of a desired cross section in indefinite length.
Scabs are primarily an ingot process issue related to teeming, but we have seen them on continuous cast products as a result of mold and tundish anomalies. Scabs present with scale beneath; Cracks may (but are not always) be present associated with the scab due to stress concentration causing the material underneath to crack.
Roll cleaner assemblies are comprised of a roll cleaning blade, blade holder, structural beam, brackets, and bearings along with an option to oscillate. They provide continuous roll cleaning for a variety of industrial roll and belt applications. These systems are designed to use a .
