In recent years, secondary vacuum refining technique gets popular and further developed. The heart of global metallurgical industry has transferred from quantitative to be variety diversification and high quality. The super purity index reflects the quality of product, The effective way to achieve super purity index is secondary vacuum refining technique. There are many ways of secondary vacuum refining, the most popular ways are:1, VD- ladle vacuum refining process.2, VOD- vacuum oxygen decarburization ladle vacuum refining process.
VD/VOD ladle vacuum refining process strengthens blowing argon reasonably on the bottom of furnace; it can stir molten steel adequately and get ideal dynamics effect. If combining VD and LF, the furnace can get ideal molten steel refining temperature with easy structure and low cost. Both of the above process can dehydrogenize, denitrify, desulfurize, deoxidize under vacuum conditions and get the function of Vacuum Oxygen Decarburization (VOD) to achieve the purpose of refining super pure steel.
Vacuum pump system is the main equipment of vacuum refining device. Base on our ten years’ experience of test research and generalized application, two series products. Full steam jet vacuum pump system and Steam jet + water ring vacuum pump system had formed. Full steam jet vacuum pump series uses a certain pressure water steam and cooling water as working medium of the pump, “Steam jet +water ring vacuum pump system uses a certain steam pressure, less water steam and cooling water as working medium, and consume few electricity. The steam consumption of Full steam jet vacuum pump is relative high, and need to equip with bigger boiler, but the cost of vacuum pump itself is lower. The steam consumption of Steam jet +water ring vacuum pump system is relative low, and can equip with a smaller boiler, but the vacuum equipment itself cost higher. So the total invest cost of above system is basically consistent, both is satisfied the requirement of producing molten steel by secondary vacuum refining.
The burning loss of tuyere, refractories and chrome is influenced greatly by the temperature of molten steel. So we can offer a special online temperature measuring system to buyers.
We adopt secondary combustion of top lance technology. It can increase the volume of cold material put into the VOD and shorten the duration of smelting, and guarantee the continuous casting for multiple furnaces at last.
We also use the charging system with a weigh on its multiple bunkers, which can be directly connected with control system of computer. Then the smelting cycle will be shortened and labor intensity will be reduced.
As a professional manufacturer and designer of VD/VOD Furnace, we can offer various kinds of products with advanced mechanical equipments and experienced technical workers that we can provide this product on top quality and best price. The product will be shipping from China factory directly to your offered address. We are confident to be the best supplier in China.
