Problems solved by technology

[0004] In the prior art, as the matrix of diamond saw blades, steel types with carbon content above 0.65 (wt%) are generally used (such as 65Mn, SKS5, SKS51, 15LM, 80CrV and 75Cr1, etc.), these steels are high Carbon tool steel and high-carbon low-alloy tool steel are characterized by high strength, high strength / toughness ratio, and low plasticity and toughness. As the matrix of diamond saw blades, cracks are prone to appear during the production process, difficult to level, and low service life; It is not suitable to use more advanced laser welding methods for joining

Embodiment Construction

[0027] Adopt chemical composition of the present invention and production method, produced 3 furnaces (being 3 batches) diamond saw blade matrix steel. The chemical composition of the 3 furnace steel is shown in Table 2. 3 furnace steel is smelted, ingot-cast, and hot-rolled into a 5mm-thick plate, and the 5mm-thick hot-rolled plate is used as a base blank, and then heat-treated. The process parameters of heat treatment are shown in Table 3. The three batches of substrates were sampled after treatment, processed into corresponding samples, and tested for mechanical properties. The results are listed in Table 4.

Abstract

A matrix steel of diamond saw blade contains C (0.35-0.65 wt.%), Si (0.1-0.35 wt.%), Mn (1.2-2 wt.%), V (0.06-0.2 wt.%), Al (0.02-0.06 wt.%) and Fe (the balance), and is prepared through smelting, casting, hot rolling, quenching and annealing. Its advantages are high strength, low strength / toughness ratio, and better thermal plasticity and stability.

Description

technical field [0001] The invention belongs to the field of alloy steel, and mainly relates to diamond saw blade base steel. Background technique [0002] Diamond saw blades have been widely used in non-metallic hard building materials such as stone and cement products. The diamond saw blade is composed of two parts: a diamond segment and a saw blade base, which can be joined by sintering, high-frequency welding and laser welding. [0003] As the steel grade of the diamond saw blade substrate, it requires not only sufficient strength and good ductility, but also high hardenability and thermal stability. [0004] In the prior art, as the matrix of diamond saw blades, steel types with carbon content above 0.65 (wt%) are commonly used (such as 65Mn, SKS5, SKS51, 15LM, 80CrV and 75Cr1, etc.), these steels are all high Carbon tool steel and high-carbon low-alloy tool steel are characterized by high strength, high strength / toughness ratio, and low plasticity and toughness. As t...
