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.
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) Roller hearth bright heat treatment furnace.
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) Net belt type bright heat treatment furnace.
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.
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.
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.
