Embodiment Construction

[0014] An alloy steel material for corrosion-resistant wire rod machine rolls, which contains chemical element components and mass percentages: carbon 0.8-0.9, tungsten 2.5-3, molybdenum 1.0-1.3, vanadium 1.5-2.5, chromium 5.5-6.5, niobium 0.05-0.10, holmium 0.05-0.10, Sn0.04-0.08, Mn1.3-1.5, P≤0.030, S≤0.030, the balance is iron.

[0015] The production method of the alloy steel material for the roll of the corrosion-resistant wire rod machine is as follows:

[0016] (1) Prepare pig iron and scrap iron as the source of iron matrix in a ratio of 1:1, put pig iron into the furnace to melt, desulfurize, deoxidize, use refining agent for one-time refining, add alloy components for alloying, and then add scrap iron to melt , adding refining agent for secondary refining, testing and adjusting the content of chemical elements to pass, casting, post-casting heat treatment, etc.;

[0017] (2) The order of batches of alloying elements put into the furnace during the alloying process i...

Abstract

A corrosion-resistant alloy steel material for a roller of a wire processing machine contains the following chemical elements by mass: 0.8-0.9 of carbon, 2.5-3 of tungsten, 1.0-1.3 of molybdenum, 1.5-2.5 of vanadium, 5.5-6.5 of chromium, 0.05-0.10 of niobium, 0.05-0.10 of holmium, 0.04-0.08 of Sn, 1.3-1.5 of Mn, not more than 0.030 of P, not more than 0.030 of S and the rest of Fe. Various alloy elements, such as the holmium, the niobium and the tungsten are added on the basis of high-carbon steel and are secondarily refined, the temperature of thermal treatment after casting is reasonably controlled, and the raw materials are fed in batches, so that the alloy steel has the properties of high-speed steel, such as high-temperature resistance, high-hardness maintenance and great rigidity and toughness fitting. The surface of the corrosion-resistant alloy steel material has great wear resistance, great peeling resistance and low cold brittleness and is resistant to cold and hot alternate corrosion. The corrosion-resistant alloy steel material is suitable for being used for the roller of the wire processing machine. The cost is low due to the low alloy element content.

Description

technical field [0001] The invention relates to the technical field of rolls, in particular to an alloy steel material for rolls of a corrosion-resistant wire rod machine and a preparation method thereof. Background technique [0002] The roller is the central part of the wire rod machine, and it is the main tool for making the gadolinium-made parts and making the metal plastically deformed. The roll has a large working load, bears a lot of gadolinium pressure and torsional moment, and has a strong impact load and a large inertial force; in addition, the working environment of the roll is harsh, it has to withstand high temperature, and there is cooling water, It is working under the combination of cold and heat, and the wear is serious. [0003] There are several types of high carbon high chromium cast steel, ordinary steel and hard alloy. High-carbon high-chromium cast steel is widely used because of its wear resistance and low price. The commonly used materials for high...
