耐磨板光亮连续热处理炉基本类型

就目前来说,HARDOX450耐磨板表面进行的热处理技术算是整个生产过程中的核心技术没,尤其是现在来讲,国外普遍采用带保护气体的无氧化连续热处理炉,进行中问热处理和终的成品热处理。

At present, hardox450 wear-resistant plate surface heat treatment technology is the core technology in the whole production process, especially now, foreign countries generally use non oxidation continuous heat treatment furnace with protective gas for intermediate heat treatment and final product heat treatment.

在HARDOX耐磨板生产厂家看来,根据目前世界发展的趋势,光亮连续热处理炉基本分为以下几种类型:

According to HARDOX wear plate manufacturers, according to the current world development trend, bright continuous heat treatment furnace is basically divided into the following types:

(1)辊底式光亮热处理炉。

(1) Roller hearth bright heat treatment furnace.

这种炉型适用于大规格、大批量HARDOX450耐磨板热处理,小时产量在1.Ot以上。可使用的保护气体为高纯度氢气、分解氨及其他保护气体。可以配备对流冷却系统,以便较快地冷却450耐磨板。

This type of furnace is suitable for heat treatment of hardox450 wear-resistant plates with large specifications and batches, and the output per hour is more than 1.0T. The protective gases that can be used are high purity hydrogen, decomposed ammonia and other protective gases. Convection cooling system can be equipped to cool 450 wear plate quickly.

(2)网带式光亮热处理炉。

(2) Net belt type bright heat treatment furnace.

这种炉型适合于小直径薄壁精密HARDOX耐磨板,小时产量约为0.3~1.0t,处理钢管长度可达40m,也可以处理成卷的毛细管。配备对流冷却系统可进行快冷。

This furnace type is suitable for small diameter, thin wall and precision HARDOX wear-resistant plate. The output per hour is about 0.3-1.0t. The length of steel pipe can be up to 40m. It can also be used to process coiled capillary tubes. Equipped with convective cooling system for rapid cooling.

使用气体燃料或电加热,可采用各种保护气体。经过这种炉型热处理后的耐磨板无划伤,光亮度好。

Using gas fuel or electric heating, various protective gases can be used. After heat treatment, the wear-resistant plate has no scratch and good brightness.

经过如此大幅度的进行修改,由于可以获得无氧化的光亮表面,从而取消了传统的酸洗工序。这一热处理工艺的采用,既改善了HARDOX450耐磨板的质量,又克服了酸洗对环境的污染。

After such a large modification, the traditional pickling process is cancelled because the bright surface without oxidation can be obtained. This heat treatment process not only improves the quality of hardox450 wear-resistant plate, but also overcomes the environmental pollution caused by pickling.
