Problems solved by technology

[0002] The steel rim wheel is the wheel hub, which is a barrel-shaped metal part that is supported by the inner profile of the tire and is centered on the shaft. The surface of the steel rim wheel that has just been processed is surface treated to improve the surface mechanical properties of the steel rim wheel, but the existing steel rim wheel surface treatment process cannot meet the needs of long-term work in some harsh environments

Embodiment Construction

[0018] A steel rim wheel surface treatment process, comprising the following steps:

[0019] 1) cleaning

[0020] Put the steel rim wheel into the cleaning agent, soak for 20 minutes first, then use ultrasonic vibration for 15 minutes at 36-40°C, then boil the cleaning agent to boil, let the steel rim wheel soak in the boiling cleaning agent for 30 minutes Minutes later, take out the steel rim wheel and dry it at 42-48°C; the cleaning agent is made from the following raw materials in parts by weight: sodium lauryl sulfate 4, sodium N-acyl glutamate 3, sodium lactate 2 , sodium lignosulfonate 1, alkanolamide 2, triethanolamine 4, sodium laurate 0.1, sodium citrate 2, turpentine 1, isopropanol 0.2, chlorophyll 0.01, capsicum 0.01, water 70;

[0021] 2) Surface preheating

[0022] Put the steel rim wheel in a vacuum first, and adjust the temperature to 36-40°C. After 50s, put the steel rim wheel into a nitrogen environment at a temperature of 220-230°C, and heat preservation fo...

Abstract

The invention discloses a steel ring car wheel surface treatment process. The steel ring car wheel surface treatment process comprises the following steps of (1) cleaning, (2) surface preheating, (3) surface modification treatment, (4) cleaning and cold standing and (5) quenching treatment. The steel ring car wheel surface treated through the process has the high abrasion resistance, high hardness, high toughness and high shock resistance, subsequent quenching treatment is matched, the optimal quenching time and quenching temperature are optimized, and the tempering time and tempering temperature are adjusted, so that the impact toughness and hardness of a steel ring car wheel are improved; and inner hardness and outer hardness are balanced, the microhardness of the surface of a steel ring car wheel coating is quite high, the salt corrosion resistance and stress corrosion cracking resistance can be further improved. In addition, the fatigue resistance of the steel ring car wheel is greatly improved, the service life of the steel ring car wheel is prolonged, and the service life of the steel ring car wheel is prolonged by three to four times compared with untreated steel ring car wheels.

Description

technical field [0001] The invention relates to the field of metal surface treatment, in particular to a steel rim wheel surface treatment process. Background technique [0002] The steel rim wheel is the wheel hub, which is a barrel-shaped metal part that is supported by the inner profile of the tire and is centered on the shaft. The surface of the steel rim wheel that has just been processed is surface treated to improve the surface mechanical properties of the steel rim wheel, but the existing surface treatment process of the steel rim wheel cannot meet the needs of long-term work in some harsh environments. Contents of the invention [0003] The purpose of the present invention is to provide a steel rim wheel surface treatment process, achieved through the following technical solutions: [0004] A steel rim wheel surface treatment process, comprising the following steps: [0005] 1) cleaning [0006] Put the steel rim wheel into the cleaning agent, soak for 20 minut...
