Description
This dataset is a market dataset representing the consumption market of the region. The dataset includes the transport of the product from the gate to the consumption end, and the transport service is calculated based on the transport situation of the product in the region. The product represented by this dataset is titanium and titanium alloy ingot, a densified titanium-based formed metal billet prepared from titanium sponge through the melting and casting process. The product has the core characteristics of low density and high specific strength, can form a dense and stable oxide film in air, and possesses excellent corrosion resistance; it has a relatively high melting point and good thermal stability, and some titanium alloys can still maintain excellent mechanical properties under high-temperature conditions. At the same time, titanium and titanium alloy ingots are non-magnetic and have relatively low thermal conductivity, as well as good biocompatibility. The upstream raw material of the product is titanium sponge; downstream it can be made into various titanium materials and titanium alloy components through forging, rolling, machining and other processes, widely used in aerospace, high-end chemical anti-corrosion, medical devices, marine engineering, precision equipment manufacturing and other fields, being the core basic forming material for the terminal application of the titanium industry. The dataset includes the main raw and auxiliary materials, energy and waste of the production process; infrastructure such as production equipment manufacturing and plant construction is not included within the dataset boundary; the data inventory is formed by merging data from multiple sources.
Activity Description
The production process comprises melting and casting. Titanium and titanium-alloy round ingots are produced by vacuum arc remelting, while titanium and titanium-alloy rectangular ingots are melted in an electron-beam cold-hearth furnace. The system covers the full process from titanium sponge to titanium and titanium-alloy ingots.
Process Description
Titanium and titanium alloy ingots have the outstanding characteristics of low density and high specific strength. At the same time, they can form a dense and stable oxide film in the air, thus showing excellent corrosion resistance. They have a high melting point and good thermal stability. Some alloys can still maintain good mechanical properties in high temperature environments. In addition, titanium is non-magnetic, has low thermal conductivity, and has good biocompatibility, which can meet the special needs of aerospace, chemical industry, medical and other fields.

Technology comment
During the melting and casting process, titanium and titanium alloy round ingots are melted using vacuum consumable arc melting, while titanium and titanium alloy flat ingots are melted using an electron beam cold hearth melting furnace. The overall process flow is as follows: titanium sponge and clean scraps are mixed according to the process ratio through a weighing and mixing system as smelting raw materials. The raw materials are added to the smelting chamber and then evacuated. After the furnace body is preheated, the raw materials are fed into the molten pool through a vibrating feeder for melting. At the same time, they are sequentially scanned and heated by the electron beam gun. The initially melted titanium liquid flows into the refining molten pool, where high-density and low-density inclusions are separated from the titanium melt. The refined liquid titanium enters the crystal pulling crucible and solidifies at the set ingot pulling speed to form a rough ingot. The rough ingot is controlled to crystallize in the furnace and then taken out to obtain titanium and titanium alloy ingots.
