热处理与HARDOX400耐磨板表面质量的关系

所属分类:常见问题 发布时间:2020-10-14 11:07:29 来源:http://www.lcnmb500.com 浏览量:

HARDOX400耐磨板生产后不能立即使用。必须经过热处理,保证产品质量,才能更放心的使用。

Hardox400 wear-resistant plate can not be used immediately after production. Must pass through heat treatment, guarantee product quality, can use more at ease.

热处理可以进一步提高产品质量和使用寿命,HARDOX400耐磨板的表面质量也取决于耐磨板的热处理工艺,因此耐磨板的热处理是整个生产过程中的重要环节。

Heat treatment can further improve the product quality and service life. The surface quality of Hardox400 wear-resistant plate also depends on the heat treatment process of Hardox400 wear-resistant plate, so the heat treatment of Hardox400 wear-resistant plate is an important link in the whole production process.

如果耐磨板表面的氧化皮厚度不均匀,则厚薄处下的母材表面光洁度不同,表面氧化皮的溶解和附着氧化皮部分的母材腐蚀程度也不同,因此耐磨板表面不均匀。

If the thickness of oxide scale on Hardox400 wear-resistant plate surface is not uniform, the surface finish of base metal under the thickness is different, and the dissolution of oxide scale on the surface and the corrosion degree of base metal of attached oxide scale are also different, so the surface of Hardox400 wear-resistant plate is not uniform.

因此,在热处理和加热过程中,有必要均匀地形成氧化皮。要达到以下条件,需要注意的是:如果在加热过程中,工件表面附着了油,那么油附着部位的氧化皮的厚度和成分会与其他部位不同,会发生渗碳。氧化皮下的母材渗碳部分会被酸严重侵蚀。初燃时重油燃烧器*喷出的油滴如果附着在工件上会产生很大的影响。

Therefore, it is necessary to form oxide scale uniformly during heat treatment and heating. In order to achieve the following conditions, it should be noted that if oil is attached to the surface of the workpiece during heating, the thickness and composition of oxide skin on the oil attachment part will be different from other parts, and carburization will occur. The carburized part of the base metal under oxidation will be seriously eroded by acid. During the initial combustion, if the oil droplets ejected from the heavy oil burner * adhere to the workpiece, it will have a great impact.

操作者的指纹附着在工件上也会有效果。因此,浴工不应用手直接触摸HARDOX400耐磨板,也不应使工件沾上新油。如果冷加工时工件表面附着有润滑油,必须在三氯乙烯脱脂剂和烧碱溶液中充分脱脂,然后用温水清洗,再进行热处理。

The operator's fingerprint attached to the workpiece will also have an effect. Therefore, bath workers should not directly touch Hardox400 wear-resistant plate by hand, nor should the workpiece be stained with new oil. If lubricating oil is attached to the surface of the workpiece during cold working, it must be fully degreased in trichloroethylene degreasing agent and caustic soda solution, then cleaned with warm water, and then heat treated.

1、如果工件表面有杂物,加热一定会影响有机物或灰烬附着在工件上时的氧化皮。

1. If there are impurities on the surface of the workpiece, heating will certainly affect the scale of organic matter or ash adhering to the workpiece.

2、与气体或油的火焰直接接触的耐磨板表面产生的氧化皮与非接触处不同。因此,加热时,加工零件不得直接接触火焰口。

2. The oxide scale produced on Hardox400 wear-resistant plate in direct contact with gas or oil flame is different from that at non-contact area. Therefore, when heating, the processed parts shall not directly contact the flame mouth.
