Continuous Casting Rolls
Definition
The continuous casting equipment at steelworks is equipped with a number of rolls that transport slabs, such as guide rolls and pinch rolls. These rolls receive contact loads from high-temperature slabs over a long period of time. Due to repeated heating and cooling by heating with a piece and cooling with cooling water, severe damage such as wear, thermal cracking, high temperature steam oxidation, etc. is caused.
In recent years, there has been a strong demand for higher casting speeds, improved production performance and slab yield, and the surface temperature of rolls has risen, making the use environment of rolls more severe than before. Yes. Especially for top rolls (foot rolls, support rolls, guide rolls, etc.) directly under the mold, in addition to thermal crack resistance, which is a general required characteristic of continuous cast rolls, further improvement in roll wear resistance and corrosion resistance is required.
Features
1. excellent in wear resistance and corrosion resistance
2. specific alloy steel material makes the rolls in long service time
