Stainless Steel Wire Rope: a flexible rope twisted with multiple or multiple strands of fine steel wire. The steel wire rope is twisted into strands by multiple layers of steel wire, and then takes the core as the center, and is twisted into a helical rope by a certain number of strands. In material handling machinery, it is used for lifting, pulling, tensioning and carrying. The steel wire rope has high strength, light weight, stable operation, not easy to break suddenly and reliable operation. The steel wire rope plays the role of bearing the load, and its performance is mainly determined by the steel wire. The steel wire is a round (or special-shaped) wire made of stainless steel, carbon steel or alloy steel by cold drawing or cold rolling.

300KG medium frequency induction furnace steelmaking process
The "lads" section here seems incomplete, but I’ll focus on the process described afterward. The material is melted in a 300KG medium frequency induction furnace using common scrap steel, ferrosilicon, ferromolybdenum, and ferromanganese. Prior to melting, the graphite is carbonized, and the raw materials are baked and treated to remove slag, which helps reduce gas content and inclusions in the molten steel.
To enhance the molten steel’s purity further, an argon blowing technique is employed. Venting bricks are installed at the bottom of the ladle, allowing argon gas to flow through the ceramic structure, stirring the steel while also creating fine, dispersed bubbles that aid in degassing. This process ensures even distribution of alloy elements and deoxidation products, improves temperature uniformity, and minimizes issues like ladle bottoming. It also enhances the toughness of high-silicon cast steel.
Before the furnace is discharged, the molten steel’s composition is checked using a fast spectrometer to ensure accuracy. During refining, 0.1% silicon calcium is used as a deoxidizer, followed by final deoxidation with 0.2% aluminum blocks. Once the steel is discharged (at temperatures above 1600 degrees), the mixed rare earth alloy containing cerium, lanthanum, and vanadium-titanium iron is crushed into pieces smaller than 15mm. These fragments are dried at temperatures below 200 degrees and placed in the lower part of the ladle for water-based compound modification via the in-package method.
For high-silicon cast steel, the austenitizing temperature ranges between 880-1080 degrees Celsius, with a holding time of over 2 hours. Subsequent heat treatment occurs in a salt bath furnace at 260-360 degrees Celsius, where isothermal holding lasts for 2-4 hours.
This entire process is crucial for achieving the desired mechanical properties and microstructure in high-silicon cast steel, ensuring it meets the required standards for various industrial applications.
