Embodiment Construction

[0016] The titanium scrap recycling and remelting process of the present invention is: crushing→screening→cleaning→draining→drying→magnetic separation→packing→secondary drying→putting into the furnace.

[0017] The above-mentioned titanium scrap recovery and remelting process, the steps of the titanium scrap recycling and remelting process are: the spiral ribbon-shaped scrap material 1 loaded in the sponge titanium bucket first needs to be processed into scraps by a metal pulverizer 2, and then needs to be processed into scraps. Ultrasonic cleaning machine 3 cleans and removes oil stains. After comparing various cleaning methods, it is determined that ultrasonic cleaning is the most practical method. Finally, rinse the residual detergent, dust and stains with clean water in the washing tank 4, drain the water and load it into the running trolley In the net cage 5, send it into the box dryer 6 to continue to remove the remaining water by heating to accelerate the water distribut...

Abstract

The invention relates to a processing technology for a great deal of titanium scraps produced from the processes of surface planing and milling and end surface cutting off of unpolished ingots produced from the casting of titanium ingots. The titanium scrap processing technology is a titanium scrap recycling and remelting technology which is characterized by comprising the following steps: pulverizing, screening, washing, water drainaging, drying, magnetic separating, packing, secondary drying and putting into the furnace. The titanium scrap recycling and remelting technology provides a set of processing scheme of high safety, reliability, practicability and efficiency and low cost for secondary recycling casting of the titanium scraps produced from the processes of surface planing and milling and end surface cutting off of the unpolished ingots produced from the casting of titanium, and the whole titanium scrap recycling and remelting technology is low in labor and time consumption; meanwhile, the space arrangement of devices is compact and reasonable, the process is coherent, the operation is convenient, the processing result is radical, and the general requirements to recycle, remelt and process titanium scraps of titanium ingot casting manufacturers can be met.

Description

technical field [0001] The invention relates to a process for treating a large amount of titanium chips produced by surface planing and milling of rough ingots produced by melting and casting of titanium ingots and end face cutting. Background technique [0002] Titanium metal is easy to oxidize and burn. Titanium ingot melting and casting production needs to be carried out in a high vacuum environment to avoid the oxidation of titanium metal and the influence of gas on high-voltage arc or high-voltage electron beam during smelting. The current mainstream melting and casting equipment in the world is mainly vacuum self-consumption. Furnace and electron beam melting furnace, while the latter has a strong technical advantage for the remelting of titanium recyclate and scrap. The surface planing and milling of the ingot and the section cutting produce a large amount of titanium chips, and the doping of non-metallic elements such as C, H, O, N and other metal elements such as Fe...
