How to deal with titanium rods and titanium alloy residues? Let me share with you
1. Treatment of crumbs
The technological process of scrap-like residue processing is: residual titanium scraps-crushing-washing-drying-screening-removing high-density metal inclusions-cloth-inspection> packaging and storage. The shavings can be crushed by herringbone gear rollers Crushing with a crusher or hammer crusher. Cleaning is carried out on a washing machine. Use a hot-air dryer or an electric dryer to dry clean titanium chips. Titanium chips are screened in a double-hole sieve. After screening, scoop The chips are separated by an air separator, and then processed by a strong magnetic separator to remove high-grade metal inclusions (alloy cutter heads mixed with titanium chips, etc.). Titanium chip cloth is carried out on the cloth machine to make the composition and geometric dimensions different The scraps are evenly distributed. After purification treatment, the qualified scraps are returned to the furnace.

2. Treatment of bulky residue
The processing process of blocky residues is: blocky residues-brand identification-fixed-length dome cutting/cutting-removal of surface contamination layer-inspection-packaging and storage.
1. Brand identification. Using eddy current conductivity meter, steel inspection mirror, mobile direct-reading spectrometer, etc. to identify bulky residues, it can quickly distinguish pure titanium and alloys, and determine the elements contained in gold residues, and mobile direct-reading spectrometers can also directly and accurately measure bit Vegetarian content 3.
2. Cut-to-length/cutting adopts shearing machine, crocodile shear, etc. or self-cutting with fire.
3. Alkaline washing or ultrasonic cleaning machine can be used to treat the surface oil and fEM of plates, pipes, etc., and acid cleaning or shot blasting machine can be used to treat surface oxide layers and pollution such as forging blocks.
3. Vacuum consumable electric arc furnace melting and recycling
Generally, it is necessary to prepare electrodes with a certain strength first to prevent lumps from falling during the smelting process. The four commonly used electrode preparation methods are:
1. Fully mix the swarf-like return charge or the small-sized lump return charge with sponge titanium and alloy elements, press it into an electrode block on a hydraulic press, and then weld it into a consumable electrode, which is a vacuum consumable electric arc furnace recovery Gofa, the most commonly used return charge, can add up to 40% of the return charge.
2. The return charge of the same brand is bundled in a certain proportion into self-consumption f, and the added amount of return charge can reach 100%.
3. The electrode block is used as the core material, and a certain proportion of the plate 3&tubular return charge is bundled around to form a consumable electrode. The return charge can be added up to 80%.
4. The ingot riser of the same brand and specification is made into consumable electrode by plasma argon arc welding, and the utilization rate of return charge is 100%.
