Product Details

custom alloy steel wheels are usually forged by forging.

Small size custom alloy steel wheels forging is also made of forged steel, generally no less than 45 quality steel.

Heavy custom alloy steel wheels are made of alloy steel, and some of the crane wheels are used to reduce the diameter of the wheel to reduce the height of the crane, and the wheel of the crane is made of alloy steel materials.

Gb60667-1985 it is stipulated that the thickness of the flange should be discarded when the thickness of the flange is 50% of the thickness.

"Crane design manual", points out that the custom alloy steel wheels rim crane under lateral pressure, the wheel to 70% - 80% of the itinerary and rubbing on the side of the track, because of the flange and the wheel scrapped.

Therefore, the custom alloy steel wheels rim should also be included in the heat treatment of the wheel.

If the heating induction coil is too narrow, the hardness of the inner surface of the rim will not meet the requirements.

Gb60667-1985 it is stipulated that when the thickness of the custom alloy steel wheels tread of the crane has worn down to 15% of the thickness of the original thickness, it should be scrapped.

In the process of manufacture, the surface hardness as moderate (too high will make rail serious wear and tear), and to make the crane wheel tread depth is achieved at 20 mm (too low will make the crane wheel serious wear and tear), is has the certain difficulty.

According to years of experience, when carbon content is less than 0.5% of cast steel or plain carbon steel materials, the depth of the hardened layer of the custom alloy steel wheels tread will not meet the requirements.

Crane wheels during heat treatment if the table fire quenching method, this method only 2-5 mm, the depth of hardening layer and the surface brittleness is very big, in the process of operation, the crane wheel tread appear crack, and then fall off of the hardening layer, the custom alloy steel wheels scrapped, this method should not be used.

In order to improve the bearing capacity and service life of the crane wheels, crane wheel tread of forging must be heat treatment, heat treatment requirements and within the custom alloy steel wheels tread profile hardness: 300-380 - hb, hardening layer depth of not less than 20 mm 260 hb.

Under the present technical conditions, the above requirements can be achieved by using a variety of heat treatment methods.
