喷射成形技术是一种非常有发展前景和潜能的制备技术,在高合金化材料成形和制备方面有很大优势。堆焊耐磨钢板喷射成形技术原理是熔融堆焊耐磨钢板在高压惰性气体的作用下被雾化成细小弥散的液滴,随后在高速飞行的过程中迅速冷却至过冷态,然后在凝固前沉积到收集器上形成连续致密的近终形坯件。

Spray forming technology is a promising and potential preparation technology, which has great advantages in the forming and preparation of high alloy materials. The principle of spray forming technology of hardfacing wear-resistant steel plate is that the hardfacing wear-resistant steel plate is atomized into fine dispersed droplets under the action of high pressure inert gas, and then rapidly cooled to supercooled state in the process of high-speed flight, and then deposited on the collector to form continuous and dense near net shape billet before solidification.

耐磨钢板喷射成形技术工艺大大简化,生产周期缩短,大大降低成本,可以制备近终成型的坯体;冷凝速度快,冷速高达103K/s,从而消除了组织宏观偏析,获得了精细的呈等轴状的显微组织。

The spray forming process of wear-resistant steel plate is greatly simplified, the production cycle is shortened, and the cost is greatly reduced; The cooling rate is up to 103K / s. Thus, the macro segregation is eliminated and the fine equiaxed microstructure is obtained.

不仅如此,它的高沉积率,单个产品的质量通常可达1t以上,有利于工业化生产;高合金性能优异,喷射成形材料性能(如耐蚀性、耐磨性、磁性以及强度和韧性等理化和力学性能),与粉末冶金材料相当,比常规铸造材料有较大提高。

Moreover, it has high deposition rate, and the quality of a single product is usually more than 1t, which is conducive to industrial production; High alloy, excellent properties, spray forming material properties ( Such as corrosion resistance, wear resistance, magnetism, strength and toughness and other physical, chemical and mechanical properties ) It is equivalent to powder metallurgy material and higher than conventional casting material.

具有更广泛的应用,可生产多种合金,尤其是在高温合金、堆焊耐磨钢板等高合金化材料方面具有明显优势,在堆焊耐磨钢板基复合材料方面也有广阔的应用前景。

It has a wide range of applications, can produce a variety of alloys, especially in superalloy, hardfacing wear-resistant steel plate and other high alloying materials has obvious advantages, in hardfacing wear-resistant steel plate matrix composites also has broad application prospects.

目前堆焊耐磨钢板喷射成形技术主要用于研究开发各种高性能合金产品,包括铝合金、铜合金、耐磨板、工具钢、堆焊耐磨钢板、轧辊合金以及高温合金,应用范围涉及汽车、石油化工、电子以及很多普通的工业领域。

At present, spray forming technology of hardfacing wear-resistant steel plate is mainly used for the research and development of various high-performance alloy products, including aluminum alloy, copper alloy, wear-resistant plate, tool steel, hardfacing wear-resistant steel plate, roll alloy and superalloy. Its application scope involves automobile, petrochemical, electronics and many common industrial fields.
