the time for you to know about Si-Ca alloy
Calcium silicon for sale
Calcium silicon alloy is actually a multi-alloy. The main constituent elements are silicon, calcium and some trace elements.
With the development of technology, steelmaking technology has also been upgraded. Traditional metallurgical materials obviously cannot meet the needs of steelmaking. Silicon calcium alloys are designed to meet the needs of emerging products.
Silicon and calcium in silicon calcium have strong affinity with oxygen. Silicon can have a strong affinity with oxygen. Calcium has a strong affinity with sulfur and nitrogen. Therefore, silicon calcium is an ideal composite deoxidizer and desulfurizer. It is widely used in steel making.
The metallurgical materials commonly used in the production of silicon calcium are silica, lime, and coke. It is made by fully reacting in the high temperature environment of the smelting furnace. Si-Ca alloy can greatly reduce the cost of smelting. Thereby improving efficiency.
Calcium silicon production methods
The main raw materials of silicon calcium alloy are lime, silica, calcium carbide and carbonaceous reducing agent. Requirements for raw material in the production of Si-Ca alloy>>
Production methods can be generally divided into two types: carbon thermal method and silicon heat generation.
At present, the method for producing silicon calcium in China is the carbothermal method. For Russia and Japan, the silicon thermal method is generally used.
The method of carbon-heat production of Si-Ca can be divided into two types: mixing and layering.
Silicon calcium uses
The interior of the SiCa alloy is rich in silicon and calcium. Domestically, it is mainly produced by electric furnace. However, the electric furnace production method consumes a lot of electricity. Therefore, silicon calcium alloy manufacturers are generally found in the northwest.
Silicon calcium alloy is a good deoxidizer and slagging agent in steel making.
Silicon is the main element of deoxidation during steelmaking. It has good affinity with oxygen. The deoxidation effect is particularly good.
Calcium can effectively concentrate impurities in molten steel. Thereby eliminating harmful elements such as sulfur, phosphorus and other elements in the molten steel.
Therefore, silicon calcium alloy can effectively improve the toughness and quality of steel. It is an ideal ferroalloy raw material. It can save metallurgical costs and increases the profits of manufacturers.
Silicon calcium cored wire
The silicon calcium cored wire is a wire-like shape in which silicon calcium powder is wrapped by a steel sheath. As for the proportion of silicon and calcium elements, it is necessary to look at user needs. Silicon calcium cored wire has a wide range of uses in various industries. The occupied area is small, the feeding is convenient, and the use effect is good.
What are the advantages of silicon calcium cored wire?
1. It is beneficial to adjust and control the content of easily oxidizable elements and trace elements. Can greatly increase the alloy yield. Thereby reducing smelting costs, shortening smelting time, and accurately controlling composition.
2. Can play the role of pure steel. Improve the quality of molten steel and improve the casting state.
3. The core wire is divided into two types: internal and external. The mechanical equipment required to feed the line is simple and reliable. And the footprint is small.
