Products Description
1.Melting process：Vacuum self-consumption arc furnace melting (VAR method for short)
With the development of vacuum technology and the application of computers, the VAR method has quickly become a mature industrial production technology for titanium, and most of today's titanium ingots and alloy ingots are produced using this method.The distinctive features of the VAR method are low power consumption, high melting speed and good quality reproducibility, and the ingots melted by the VAR method have a good crystalline organization and a uniform chemical composition. Normally, the finished ingot should be produced by VAR melting. At least two remelts are required. VAR method of production of titanium ingots, manufacturers around the world to use the process is basically similar, the difference lies in the use of different electrode preparation and equipment. Electrode preparation can be divided into three main categories, one is the use of continuous pressing according to the portion of material, the whole electrode, excluding the electrode welding process: the second is a single piece of electrode pressing, welding into self-consumption electrode. And through the plasma argon arc welding or vacuum welding welded into one; Third, the use of other melting method for the preparation of casting electrodes.
Technical features and advantages of modern advanced VAR furnaces:
(1) Fully coaxial power input, i.e. complete coaxiality at the height of the entire furnace body, called coaxial power supply', reduces the generation of bias phenomena;
(2) Electrical calibration in the crucible can be fine-tuned in X-axis direction/Y-axis direction;
(3) With precise electrode weighing system, the melting rate is automatically controlled, realizing constant speed melting' and ensuring the melting quality;
(4) Ensuring the repeatability and consistency of each melting;
(5) Flexibility, i.e., one furnace is capable of producing a variety of ingot types as well as large-scale ingot casting, which can substantially increase productivity;
(6) Good economy. The "coaxial power supply" method can avoid the magnetic leakage caused by the unbalanced crucible supply current. It can weaken or eliminate the unfavorable influence of induced magnetic field on the melting products. It also improves the electric efficiency, thus obtaining ingots with stable quality. The purpose of "constant speed melting" is to improve the quality of ingot casting, through the advanced electric control system and weight sensor to ensure that the length of the arc and the melting rate of the melting process is constant, so as to control the coagulation process. The segregation phenomenon can be effectively prevented and the intrinsic quality of the ingots can be guaranteed.
Modern titanium melting with VAR furnace in addition to the above two major features, but also to achieve the large-scale VAR furnace, modern VAR furnace can be melted diameter of 1.5m, weighing 32t of large ingots.
2.Characteristics of GR5 titanium ingot
High Strength & Low Density:Grade 5 titanium has a tensile strength of 900-1,000 MPa, which is approximately two times stronger compared to pure titanium. In addition, due to the low density of titanium (approximately 4.43g/cm³), grade 5 titanium is relatively lightweight, making it an ideal material for applications where strength is required along with light weight.
Excellent corrosion resistance:Grade 5 titanium has very strong corrosion resistance, especially in the marine environment, chemical media, acid and alkali environment, it can effectively resist all kinds of corrosion. Because of this, grade 5 titanium is widely used in chemical industry, marine engineering and other fields.
Good resistance to high temperatures:Grade 5 titanium is able to maintain excellent mechanical properties even in high temperature environments. It is able to withstand high operating temperatures (up to about 400°C), making it suitable for use in application scenarios with high temperature and high strength requirements.
At present, the application of gr5 titanium alloy is more and more extensive, the market demand for GR5 titanium ingot is more and more large, we will do every kind of product with all our heart.
