Abstract

The invention provides a microalloying wear resisting ball and a preparation method and a preparation system thereof. The microalloying wear resisting ball comprises the following components in percentage by weight: 0.75-0.85% of C, 0.15-0.35% of Si, 0.65-0.75% of Mn, 0.4-0.5% of Cr, 0.05-0.1% of B, 0.01-0.05% of N, 0.01-0.015% of Mg, 0.05-0.15% of Ca, S not more than 0.010%, P not more than 0.015%, and the balance of Fe. The invention further discloses the preparation method of the microalloying wear resisting ball; and the preparation method comprises the steps of induction smelting-continuous casting and rolling of rods-medium-frequency induction heating-inclined rolling and rotary cutting of balls-heat treatment process (quenching+tempering). The microalloying wear resisting ball has the advantages of high strength, high toughness, simple production process and low cost.

Description

technical field [0001] The invention relates to metallurgical technology, in particular to a microalloyed wear-resistant ball, a preparation method and a preparation system thereof. Background technique [0002] With the rapid development of society, natural resources such as energy ores are becoming less and less, the mining environment is getting more and more difficult, and the mining costs are getting higher and higher. How to reduce the consumption and cost of energy mining has become a key point of my country's energy strategy. research focus. In the industrial production of mineral resources, as the abrasive medium of the ball mill, the grinding ball plays a role in crushing and grinding the material in the production process, and its quality and performance directly affect the working efficiency and powder quality of the ball mill. Therefore, the development of high-quality grinding balls is of great significance for improving mining efficiency and reducing mining co...
