Top Quality high tensile strength ferro silicon solid calcium Casi flux cored welding aluminum steel wire
Seamless metal calcium wire is a kind of composite steel tube wire which is formed by low carbon steel band and covered with metal calcium wire.It is an alternative to the traditional "bite" core cord.It can be used to add calcium which is light weight, low boiling point, easy to oxidize and has little solubility in the molten steel, which is more economical and effective than other methods.
In the cast iron production, with seamless metal calcium core wire desulphurization, spheroidization and gestation foundry added, widening faster and faster.Take Germany, which was the first country to develop the production of ductile iron by using the technique of seamless metallic calcium clad coring. At the end of 1989, only one foundry in Germany chose the method of seamless metallic calcium clad coring to produce ductile iron.High quality products produced with low cost are the policy sought by steel mills and foundries in the world.The practice including our country has proved that the core wire skill is the most simple and agile skill method in many aspects of molten steel and iron treatment
1.Seamless metal calcium core wire is a kind of seamless solid metal calcium core wire used in steelmaking deoxygenation. It is made of three parts outer steel tube, middle coating,the inner core which is solid metallic calcium (pure calcium) line. 2.The utility model provides seamless solid metal calcium packet, core wires can reduce the vapor pressure of calcium metal and gasification rate, increase the seamless solid metal conductor inserted depth of steel liquid calcium package and reduce the boiling liquid steel, reduce the time of the metal calcium’s absorbtion by the molten steel. 3.Calcium not only overcomes the existing joint solid package conductor inserted steel liquid boiling phenomenon, but also reduce the noneffective phenomenon of feeding cored wire because of calcium powder package conductor hollow or core powder uneven weight . Avoid the harmful elements (S, P, C, Si)in calcium powder wire, thus greatly improve the yield and stability of metal calcium.It has the advantages of high tensile strength, good toughness and not easily to break.The core wire is compact and tightly wrapped, which can be stored for a longer time and can guarantee the use effect.
1. The yield of calcium in the calcium treatment process is closely related to the wire feeding speed, diameter and height ratio of ladle, wire feeding process, etc.The feeding speed is the key factor to determine whether the feeding process can achieve the desired effect. The optimum feed line speed is only a function of the depth of the molten steel. 2. The optimal feed line speed has little relation with the temperature of the molten steel treated. 3. The temperature of molten steel treatment is directly related to the yield of calcium As can be seen from the vapor pressure chart of calcium at different temperatures, the higher the temperature of the molten steel treated, the higher the vapor pressure of calcium, the faster the escape velocity of calcium from the molten steel, the shorter the residence time of calcium in the molten steel, and the lower the efficiency and recovery rate of calcium treatment. 4. The longer the effective working time of the wire feeder at the optimal speed, the higher the calcium yield 5. The performance of wire feeding machine, the processing quality of core wire and the incidence Angle and height of core wire have a significant impact on the result of wire feeding. 6. The treatment package shall have a proper height and diameter ratio.It is better to make the height of the molten steel 1.1-1.2 times the effective diameter of the ladle.
1.Pure calcium does not contaminate molten steel with other oxides in the powder cored wire.
2.The minimum specific surface area of high density mandrel core wire can minimize the calcium chloride inclusions that are deactivated due to oxidation and contaminate the molten steel
3.A more uniform calcium content per meter and a higher and more stable active calcium content ensure a more stable calcium treatment
4.High density pure calcium mandrel quality easy to detect smaller core line specific surface area to allow it to have a longer shelf life.Revolutionary seamless technology prolongs shelf life by preventing calcium oxidation in storage
The company has four core-line production lines, specializing in the production of seamless metal calcium cored series wire.Fixed monthly production is about 1000 tons, and that can be adjusted on the actual situation of customers’ request.Enough inventory to support instant delivery.
Cooperated with domestic steel mills such as Shandong Steel Group, Rizhao Steel, Hegang Group, Handan Steel Branch, Bao steel Group, Shaoguan Branch, Nanjing Steel, Xinyu Steel, Baotou Steel, new cast tube Wuhu branch, Puyang Steel Co. Ltd, South Hebei Steel Co. Ltd.Since its establishment, the company adheres to the principle of quality first, service first and customer first. So far, it has long-term foreign trade cooperation with France, India, Turkey and so on. Hope for more countries International friends talk about cooperation and exchange views.
People-oriented is the talent strategy of our company, we set up a special contribution award, for creative and colleagues at work we offer generous reward, each staff are actively involved in the innovation, added a lot of power for our company. At the same time, we also introduced advanced domestic competition mechanism for individuals and groups with outstanding contribution we are also offer vigorously support and encouragement, and greatly increase our staff personal comprehensive ability.Talents having both ability and political integrity in our company can be seen everywhere, everyone do themselves use, also is the basic strategy of company management. And the future we hope more talented people to join our group, altogether create a bright and beautiful tomorrow.
