Embodiment Construction

[0016] A surface treatment process for a steel ring of a forklift, comprising the following steps:

[0017] (1) cleaning. Put the forklift steel ring into the cleaning agent, soak for 20 minutes first, and then use ultrasonic vibration for 15 minutes at 36-40 ° C, then boil the cleaning agent to boil, let the forklift steel ring soak in the boiling cleaning agent for 30 minutes Minutes later, take out the steel rim of the forklift and dry it at 42-48°C; the cleaning agent is made from the following raw materials in parts by weight: sodium lauryl sulfate 5, sodium N-acylglutamate 2, sodium lactate 3, Sodium lignosulfonate 2, alkyl alcohol amide 1, triethanolamine 3, sodium alginate 0.1, sodium citrate 1, eucalyptus oil 2, maltitol 0.1, chlorophyll 0.01, capsicum 0.01, water 70;

[0018] (2) pickling. Put the steel ring of the forklift into the acid solution, soak it at 36-37°C for 20 minutes, then turn the steel ring of the forklift at 90r / min for 15 minutes, stop the rotatio...

Abstract

The invention discloses a fork truck steel ring surface treatment process, which comprises the following steps of (1) cleaning; (2) acid washing; (3) surface preheating; (4) surface deterioration treatment; (5) cleaning and cold placement; (6) quenching treatment; (7) surface treatment agent treatment. When being used for treating the surface of a fork truck steel ring, the fork truck steel ring surface treatment process has the advantages that the wear resistant performance is good; the hardness is high; the toughness is high; the anti-impact performance is high; the subsequent quenching treatment is matched; the best quenching time and quenching temperature are optimized; the tempering time and the tempering temperature are regulated, so that the impact toughness and hardness of the fork truck steel ring are improved; in addition, the inner hardness and the outer hardness are balanced; the micro hardness of the surface of the coating layer of the fork truck steel ring is very high; the slat corrosion resistance and the stress corrosion cracking resistant performance can be further improved; in addition, the anti-fatigue intensity of the fork truck steel ring is greatly improved; the service life is prolonged, and is prolonged by 3 to 4 times through being compared with the service life of the untreated fork truck steel ring.

Description
