This article is emphasized on the design thoughts? the components and the characters of production line automatic control system of solution heat treatment furnace for automobile aluminum wheel hub, it is first designed and manufactured in china, compared with the same input systems at the end of 90's ,the precision of temperature control is higher, the function is more complete and the performance is more creditable, the excellence of switched reluctance motor is more distinct.
The process formula and flows of colour electrophoresis finishing on the fan blade of nickel-plated aluminum wheel, the stripling of substandard film and the advantage of colour electrophoresis finishing were introduced.
Application of electrolytic low titianium A356 alloys will be beneficial to shorting manufacture proceeding,lowering manufacture cost,improving products mechanical properties and reducing products weight,it is the upstanding material to cast aluminium wheel with high properties.
Experimental results showed that the performance of ZL101A alloy modified by this process was superior to that by Ti and Sr and the costs were rather lower. This method was ideal to modify aluminium hub material.
The results show that the process technique is improper according to the standard. The existence of hole and the appearance of abnormal phase reduce the mechanical properties. They cause the brittle cleavage fracture of aluminium motor wheel.
