Problems solved by technology

[0004] These commonly used saw blade steel grades mentioned above have some problems when they are produced in steel mills or when they are processed and made by saw blade manufacturers: 1. The hardenability is poor, resulting in low hardness of saw blades after heat treatment (such as 45, 30CrMo , 50Mn2V); 2. Insufficient hardenability, resulting in low and uneven hardness of the steel plate after quenching, making it impossible to manufacture thick and large-size saw blades (such as 45, 30CrMo, 65Mn); 3. Slab continuous casting and hot rolling are difficult, The slab defe

Abstract

The invention discloses an alloy saw blade with different materials, wherein the alloy saw blade includes the components by weight: 0.55-0.9 of carbon; 1-2 of silicon; less than or equal to 0.2 of manganese; 0.1-0.5 of chromium; and less than or equal to 0.2% of a trace element selected from one of niobium, tantalum, vanadium, titanium, zirconium, aluminum, sulfur, phosphorus and nitrogen or combinations thereof; and the balance iron. The steel alloy saw blade has tempering martensite and the remaining carbides; moreover, the steel alloy saw blade is hardened at the temperature of 780 DEG C-1000 DEG C and tempered at the temperature of 200 DEG C-550 DEG C. With cooperative addition of the trace element, grain refinement is produced, mold casting is facilitated and refining treatment is convenient; at the same time, the hardness of the saw blade is improved by hardening and tempering treatment, and cutting is convenient.

Description

technical field [0001] The application belongs to the technical field of saw blades, in particular, it relates to an alloy saw blade with different materials. Background technique [0002] Saw blades rotate at high speed to cut wood, stone, metal and building structures, etc., and bear large radial and axial stresses. Saw blades are required to have high elastic limit, stiffness, fatigue strength, wear resistance and impact toughness. Therefore, there are strict requirements on the chemical composition, metallurgical quality, and mechanical properties of saw blade steel. For example, saw blade steel is required to have high rigidity and toughness, low heat sensitivity, high red hardness, and hardenability. [0003] At present, the steel types commonly used in the domestic manufacture of saw blades are medium carbon saw blade steel, medium carbon low alloy saw blade steel, high carbon saw blade steel and high carbon low alloy saw blade steel. The representative grades are 4...
