The start-up speed of rolling mill equipment during operation plays an important role in the efficient operation of the rolling mill. If the start-up speed of rolling mill equipment is slow when preparing for operation, it will not only seriously affect the working efficiency of the rolling mill, but also the force between the billet excerpt …

What is a rolling mill? A rolling mill is a device that realizes the metal rolling process, and generally refers to the equipment that completes the entire process of rolling production. According to the number of rollers, rolling mills can be divided into two-roller, four-roller, six-roller, eight-roller, twelve-roller, eighteen-roller, etc.; according to the arrangement of excerpt …

Titanium (Ti)        Final deoxidizer, the deoxidizing power is not as good as Al and Zr, but stronger than Si and Mn. It is usually used as an additional deoxidizer when controlling the amount of Al and N. Rare earth elementsThe effect is similar to that of silicon-calcium alloys (i.e. dense cerium alloy, excerpt …

Common deoxidizers for cast steel smelting usually include: aluminum, calcium, manganese, silicon, titanium, rare earth, etc. Aluminum (Al) Final deoxidizer, deoxidation product Al2O3, melting point 2050℃, hardness HV3000. Calcium (Ca)      Final deoxidizer, deoxidation product CaO, melting point 2600℃. Manganese (Mn) is generally used as a deoxidizer in the middle or end of the melting process. excerpt …
