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 ( total [H]、[N]、[O]、[S]、[P] get 50ppm,or even lower) 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 costs higher. So the total investment cost of above system is basically consistent, both are satisfied the requirement of producing molten steel by secondary vacuum refining.
Our company is a Key enterprise and professional manufacturer of steam jet vacuum pump and whole vacuum equipments in China, and we are also the first corporation of designing and producing VD/VOD Vacuum refining equipment and VC Vacuum Cast Equipment in China. Up to now, we had designed and produced more than 180 sets VD/VOD, RH vacuum refining equipment, VC vacuum casting equipment for more than 100 companies. All these equipments meet the requirements of design and well received by the end user.
- Q: What is the difference between industrial furnaces and boilers?
- Hot water or steam generated in the boiler can directly provide necessary energy for industrial production and people's life, but also by the steam power device is converted to mechanical energy, or through the generator converts mechanical energy into electrical energy. Hot water boilers are called hot water boilers. They are mainly used in daily life, and are also used in industrial production. Steam generating boilers are called steam boilers, often referred to as boilers. They are used in thermal power stations, ships, locomotives and industrial and mining enterprises.
- Q: Should the industrial furnace shell cool down?
- Normally, the furnace shell temperature of an industrial furnace is below 50 degrees, so there is no need to cool down.
- Q: Heat treatment equipment (industrial furnace), which products generally contain what kind of, which industries need to use heat treatment industrial furnace equipment.
- The general metal die casting plant and the metal smelting plant need process melting and dissolving furnace, usually there are reverberatory furnace, cupola, rotary furnace, etc. I do the melting furnace of aluminium alloy.
- Q: What are the combustion equipments used in industrial boilers?
- The boiler is an energy conversion equipment. The energy input to the boiler has the chemical energy and the electric energy in the fuel. The boiler outputs steam with certain heat energy and high temperature water.
- Q: What is industrial furnace masonry?
- Plane construction must level, slope construction must find slope,refractory bricks must be selected and processed according to masonry requirements.
- Q: Why does the burner of industrial furnace burn occasionally?
- The basic structure of the complete ignition system is the ignition device and flameout protection device. The ignition burner includes an ignition electrode and an igniter (equipped with some external type transformer, voltage transformer) through the above 10kV, the ignition electrode spark ignition of high voltage discharge to ignite gas column.
- Q: How many kinds of industrial electric furnaces are there?
- Industrial furnace according to the heating mode is divided into two categories: one is the fuel furnace, combustion heat with solid, liquid or gaseous fuel in the furnace for heating the workpiece; the second is in the furnace, the furnace converts electrical energy to heat the heat.
- Q: What are the advantages of a vacuum furnace?
- Energy consumption is lower than salt bath furnace. Modern advanced vacuum industrial furnace heating chamber is made of high quality heat insulation material and wall, which can concentrate electric heating energy into heating chamber with remarkable energy saving effect.
- Q: What is the difference between industrial furnace masonry and ordinary masonry?
- Furnace industry is not generally Mason walls, needs to have a professional operation and rich construction experience, high level of industrial furnace is difficult to get.
- Q: Brief introduction to repair of industrial furnace
- Compared with other equipment, industrial furnace repair has many characteristics: more repair times, more maintenance costs, more non-standard equipment and unsafe factors.
