Embodiment 1

[0011] A high-hardness blow bar, which contains the following chemical components in mass percent: C: 2.4%, Si: 0.4%, Mn: 0.42%, Cr: 0.33%, Mo: 1.2%, V: 0.2%, Nd: 0.02% , P: ≤0.02%, S: ≤0.03%, the balance is iron and unavoidable impurities.

Embodiment 2

[0013] A high-hardness blow bar, which contains the following chemical components in mass percent: C: 4.6%, Si: 0.6%, Mn: 0.68%, Cr: 0.45%, Mo: 2.2%, V: 0.3%, Nd: 0.06% , P: ≤0.02%, S: ≤0.03%, the balance is iron and unavoidable impurities.

Embodiment 3

[0015] A high-hardness blow bar, which contains the following chemical components in mass percent: C: 4.5%, Si: 0.5%, Mn: 0.68%, Cr: 0.4%, Mo: 2%, V: 0.3%, Nd: 0.04% , P: ≤0.02%, S: ≤0.02%, the balance is iron and unavoidable impurities.

[0016] A variety of rare elements are added to the chemical composition of the high-hardness blow bar to increase its high hardness, enhance its wear resistance, and reduce the wear rate of the blow bar. Often with the increase of hardness, the brittleness of the blow bar will decrease instead, so more C and Si are added to improve the plasticity of the blow bar so that it can resist the impact of stones and avoid the blow bar from cracking.

[0017] P and S: Phosphorus and sulfur are impurity elements in the alloy and are harmful. In order to improve toughness and corrosion resistance, their content should be reduced as much as possible. Therefore, the sum of the mass percentages of P and S is controlled below 0.03%.

Abstract

The invention relates to the technical field of blow bars, and discloses a high-hardness blow bar, which contains the following chemical components in mass percentages: C: 2.4-4.6%, Si: 0.4-0.6%, Mn: 0.42-0.68%, Cr: 0.33 ‑0.45%, Mo: 1.2‑2.2%, V: 0.2‑0.3%, Nd: 0.02‑0.06%, P: ≤0.02%, S: ≤0.03%, and the balance is iron and unavoidable impurities. The cemented carbide blow bar has high hardness, good wear resistance, long service life and is not easily damaged.

Description

technical field [0001] The invention relates to the technical field of blow bars, in particular to a high-hardness blow bar. Background technique [0002] Crusher, also known as stone crusher, as the name suggests, is a kind of equipment for crushing stones. It is widely used in the crushing of various ores and bulk materials in mining, smelting, building materials, roads, railways, water conservancy and chemical industries. There are many types of crushers, and the most commonly used one is the impact crusher. Impact crusher, also known as impact crusher, is named according to the working principle, that is, it uses the principle of impact crushing to crush materials. It is a crusher equipment that crushes materials more finely than jaw crushers. It is mainly used in stone production lines. For fine crushing operations, it usually cooperates with jaw crushers for crushing. The crushing structure of the impact crusher is a rotor with a blow bar. The stone is crushed due t...
