High-quality metallurgical additive, ferrosilicon-barium alloy

1. Product introduction:

Silicon-barium alloy is an alloy product smelted by electric furnace, and its smelting materials are silica, coke, steel shavings, and barite.

The grades of silicon-barium alloys are 2850.2550.2050.1550.1055.560.260, which is an important indicator for users to purchase products. The content index we are talking about is shown in the grade. The silicon-barium alloy uses the national standard grade. If the user does not explicitly require trace elements, it will be implemented according to the national standard. The price of different indicators must be different, and there is also particle size packaging. The products produced are mostly natural blocks. The natural block of silicon-barium alloy refers to the alloy above 100mm. This alloy is usually crushed by a crusher, and it can be used after crushing. Machines are processed into standard blocks of 10-50, 10-60, or 10-70, and some manufacturers let people smash them into standard blocks. So the price of standard blocks is a little higher than that of natural blocks. There are also many packages, such as tons of packages, tons of packages plus small bags, and small bags are also divided into 10kg and 25kg.

2. The function of the product:

①. Silicon-barium alloy is used as an inoculant, which is suitable for gray cast iron and ductile iron, and can promote the formation of "A" type graphite to form graphite balls.

②. Silicon-barium alloy can nucleate in a wide temperature range, has strong spheroidizing ability and anti-recession ability, and can effectively prevent the whitening tendency of castings.

③. When the silicon-barium alloy containing 10%-35% barium is used as a deoxidizer for steelmaking, it has high utilization rate and strong desulfurization ability, which is better than silicon-calcium alloy.

④. The addition of silicon-barium alloys in the steelmaking process can make important changes in the nature and distribution characteristics of non-metallic inclusions in steel.

3. Product advantages：

The advantage of adding silicon-barium to casting is that the barium-containing activated nuclei are stable for a long time and make the inoculum more resistant to decay. The material is very useful in casting large parts and often delayed production lines, barium and calcium form an easily removed slag, since the barium containing slag will mainly remain in the ladle, it is easy to keep the stopper rod and casting machine clean.
