Abstract
The composite electroslag remelting technology was prepared with Cr12Mo1V1 steel as matrix, and the WC particles as hard phase steel bonded carbide. By means of metallographic analysis and scanning electron microscopy and other methods to study the microstructure and grinding crack morphology of the composites, and rockwell hardness and friction and wear experiment was carried out. The results show that WC particles had no obvious slant phenomenon, partly dissolved in the steel matrix, Fe3W3C multiple carbides precipitated after cooling. And the external hardness and abrasion resistance fo the roll were higher than the core, combined with good WC particles and steel matrix, and wear surface grinding marks was small, shallow furrowed, improved the roll wear resistance and service life.
