In the process of refining metallurgy, the temperature control of titanium products is very important. There are many matters that need to be paid attention to, otherwise the refined titanium products will be unqualified, so what should we pay attention to?
Excellent temperature control is the basis to ensure the smooth completion of the metallurgical process. For example, dephosphorization not only requires high oxidation and high alkalinity slag, but also requires excellent temperature matching. This is why the early dephosphorization should be emphasized. At that time, the lower temperature was conducive to de-disc; and in the quintessential period of oxidation, in order to form a lively carbon-oxygen jubilation, a higher temperature (greater than 1550) was required; metallurgical engineering for the furnace post-treatment and round casting to proceed normally, based on The different technologies selected require a certain degree of superheat in the primary titanium liquid of the electric furnace to compensate for the temperature loss during the titanium process, the essence of the furnace and the transportation of the titanium liquid.
The temperature of titanium should be determined according to the titanium species and the above factors should be fully considered. The temperature of the titanium is too low, the fluidity of the titanium liquid is poor, and it is easy to form short-scale or condensed titanium in the package after casting; the titanium temperature of the metallurgical engineering is too high, which makes the cleanliness of the titanium worse, the disadvantages of the casting billet (or ingot) are added, and the consumption is increased . In short, the temperature of the titanium should be controlled as low as possible under the premise that the casting can be completed successfully.
Eccentric bottom titanium electric furnace has a low titanium outlet temperature (small temperature drop of titanium outlet) to save energy and reduce phosphorus return.
Modern electric furnace alloying is usually completed in the titanium bag during the process of titanium extraction. Those alloys that are not easy to vaporize and have a high melting point, such as Ni, W, Mo and other iron alloys can participate in the furnace after melting, but the operation of leaving titanium is selected Full consideration should be given to the effect of remaining titanium in the previous furnace on the composition of the titanium liquid formed in the next furnace. When titanium is produced in metallurgical engineering, the titanium temperature should be properly adjusted according to the amount of alloy added, coupled with outstanding titanium bag baking and heat compensation in the titanium bag, it can not only improve the yield of the alloy, but also not form Low temperature.
Titanium alloy is pre-alloyed when titanium is extracted, and the accurate adjustment of alloy composition is finally completed in the refined furnace. In order to make the composition adjustment in the essence process go smoothly, the metallurgical engineering needs that the adjusted composition does not exceed the standard limit during pre-alloying.
A qualified titanium product needs to pay attention to many aspects, a little negligence can lead to the occurrence of unqualified products, I hope everyone will pay attention! The above is the relevant introduction to temperature control in the process of refining metallurgy of titanium products, I hope you have some understanding. If necessary, please contact us.
