Effect of Titanium Casting Structure and Temperature
Influencing the performance of the mold is mainly the thermal conductivity, strength and yield of the mold and the stability to molten titanium. The use of high thermal conductivity, that is, large heat storage capacity, high strength, poor yield, such as machined graphite cast titanium and titanium alloy castings, usually have surface cracks. Surface cracks…

Points for Attention When Opening Die of Zinc Die Casting
Attention must be paid when opening die of zinc die casting Under the effect of injection pressure, the mold will crack at the weak place, especially the scratches or electrical machining marks on the molding surface of the mold are not polished, or the fine corners of the mold will show fine cracks prematurely. When…

Summarize the Characteristics of Titanium and Titanium Alloy Casting
The metal molds used for the casting of titanium and titanium alloys are usually made of gray cast iron (HT150 or HT200), cast steel (ZG200-400), cast copper (pure copper or brass), and a very small amount of refractory metals (such as molybdenum). Except for refractory metals, the melting points of these materials are lower than…

Technology For Removing Oxide Film Of titanium Alloy Rod
In industrial production, the degree of oxidation of titanium alloy rods may vary greatly. If the oxidation of the previous process is serious, if it is severely oxidized under high temperature conditions and becomes a scale, it must be sandblasted. After blasting the workpiece, it also needs to go through the following processes (alkali washing…

Correction Of Internal Defects Of Titanium Alloy Pipe Weld
The internal defects of titanium alloy pipe welds are not fully penetrated, which refers to a defect that the workpiece is not partially fused between the weld metal or the weld layer. Incomplete penetration weakens the working section of the weld, constitutes a severe stress concentration, and greatly reduces the strength of the joint. It…

Surface Treatment Of Titanium Dioxide For Masterbatch
Through proper organic surface modification treatment, certain properties of titanium dioxide can be greatly improved.1 Chemical stabilityAfter high-temperature calcination and inorganic coating, the titanium dioxide has very good chemical stability and basically does not undergo chemical reaction with various components in the plastic system. However, some organic treatment agents may participate in chemical reactions. Therefore,…
