High-speed steel-based WC45 steel bonded hard alloy guide roller and manufacturing method thereof

Abstract

The invention discloses a high-speed steel-based WC45 steel bonded hard alloy guide roller and a manufacturing method thereof. The high-speed steel-based WC45 steel bonded hard alloy guide roller comprises a high-speed steel-based WC45 steel bonded hard alloy with chemical components including, in weight percentage, 0.6-0.7% of C, 3.0-3.2% of W, 4.0-4.5% of Cr, 3.0-3.2% of Mo, 0.5-0.8% of Si, 0.5-0.6% of Mn, 40% of WC and the balance Fe. The high-speed steel-based WC45 steel bonded hard alloy is forged, annealed, machined, treated by heat, grinded and inspected to finally form the guide roller. The prepared steel bonded hard alloy guide roller has excellent physical and mechanical properties such as high hardness, wear resistance, high-temperature oxidation resistance and heat shock resistance, the service life of the guide roller is prolonged, steel rolling production efficiency and product quality are improved, and the guide roller is low in production cost and has quite high cost performance and great economic and social benefits.

Description

technical field [0001] The invention relates to a steel rolling guide roll, in particular to a high-speed steel-based WC45 steel-bonded hard alloy guide roll used for a rolling guide device of a continuous rolling system and a manufacturing method thereof. Background technique [0002] The guide device refers to an important part that guides and guards the rolled piece to enter and exit the rolling mill during the steel rolling production process. deformation. Whether the design and use of the guide device is appropriate will directly affect the quality of the product and the production capacity of the rolling mill. [0003] The rolling guide device is a guide device that guides the rolled piece into the roll pass of the rolling mill when the rolling mill is rolling profiles, bars or wires. The guide roller is mainly a guiding equipment device for rolling steel that guides and assists the rapid passage of rolling billets or finished products. The guide roller is the most i...

Problems solved by technology

There are also reports abroad about the application of steel-bonded hard alloys in hot work dies. For example, the United States and other countries have used steel-bonded hard alloys to make single-groove or double-groove rolls for hot-rolled threaded steel bars, and for manufacturing high-speed rolling mills. Guide roller; while there are fewer reports in this area in our country
