Firstly, advanced equipment and workshop with 5S management
1) Vacuum arc remelting furnace is imported from Germany. Have advantage of automatic computer control, multiconductor, stable performance, high precision, data collection and pressure control function 2) 26 workers in drawing workshop, 3 shifts, 16 sets of advanced machines, can produce φ20-φ1.0mm medical bar and wire 3) 13 workers in straightening workshop, 3 shifts, 14 sets of advanced machines, can control the straightness to be within 0.15-0.3mm/m 4) 17 workers in plate processing workshop, 4 shifts, 18 sets of advanced machines, 2 sets of new purchased rolling machine with leading performance in China 5) 14 workers in finishing workshop, 3 shifts, 13 sets of advanced machines. The workshop can reach h6 tolerance standard, and it is in the leading place in same field
Secondly, advantage for titanium bar
1) Raw material: 0 grade undersized grain titanium sponge; 2) Melting: 3 times vacuum melting plasma welding, sampling, flaw detection, remove the head and bottom; 3) Tolerance: 100% through type detection by infra-ray diameter gauge, ensure h7, h8 tolerance; 4) Straightness: 0.3‰-0.5‰; 5) Flaw detection: 100% ultrasonic/turbine flaw detection to eliminate metallurgical defects and non-ferrous impurities; 6) Mechanical property: The tensile strength of Grade 5 diameter below 20mm can be stably controlled at 1000 (+/-25) MPa; 7) Microstructure: A1-A2 stable and uniform microstructure for Grade 5 diameter below 20mm.
Thirdly, advantage for titanium plate
1) Raw material: 0 grade undersized grain titanium sponge; 2) Tolerance:For 0.5 to 1.0mm thickness,0-0.08mm;
For 1.0 to 3.0mm, 0-0.1mm;
For 3.0 to 6.0mm, 0-0.15mm;
For 6.0mm, 0-0.2mm; 3) Mechanical property: For 1.0-6.0mm, Gr3 tensile strength can be stably controlled at 550(+/-10) MPa, and Gr5, Ti-6Al-4V ELI can be stably controlled at 1000(+/-20) MPa; 4) Microstructure: For 1.0-6.0mm, Gr3 grain size can reach to more than level 9, and Gr5,Ti-6Al-4V ELI,Ti-6Al-7Nb microstructure can be stably controlled at A1-A3 ; 5) Flaw detection: 100% ultrasonic/turbine flaw detection to eliminate metallurgical defects and non-ferrous impurities.XINNUO MAIN PRODUCTION EQUIPMENT
0 grade undersized grain titanium sponge
We use the 0 grade undersized grain titanium sponge to produce the medical and aerospace titanium ingot.
Titanium purity: Ti>99.7%
Impurity elements:Fe≤0.05% N≤0.01% Si≤0.02% O≤0.06% Cl≤0.06%
Mn≤0.01% C≤0.02% Mg≤0.02% H≤0.003%
4500T hydraulic machine for electrode preparation
Titanium sponge and intermediate alloy go through the Automatic mixer, then use the machine to press into the dense electrode block with density more than 3.6g/cm³.
ALD Vacuum melting furnace
The most advanced VAR melting furnace with full set of automatic control system.
Since September, 2017 to test run, after many batches test of different grades like Grade 3, Grade 5, Grade 7, Grade 23, the acceptance of the furnace and control software have been completed in September, 2019. The consistency of ingots’ chemical compositions is good. Yearly output is 1400 tons.
4500T forging hydraulic press
Titanium ingot forging is under the 4500 ton hydraulic machine and 1600 ton Hydraulic quick forging machine’s specific temperature range to press.
We have our own forging parameters for different grades and performance requirements’ titanium ingot, to make the breaking of grains even and sufficient.
Titanium ingot
We use our own titanium ingot, which is 3 times plasma smelted to produce the medical implants use titanium bar and sheet.
The chemical compositions are stable, consistency is good.
High precision grinding machine
For titanium bars’ straightness, surface and tolerance, we have our own control technique. The surface roughness can reach Ra≤0.8μm, and tolerance can reach h7.
Warehouse
We have the Titanium bar inventory area, Titanium sheet inventory area and printing, weighing and packing area.
Stocked around 50 tons titanium bars and 20 tons titanium sheets, can meet some urgent need orders.
