The effect of silica powder on the strength of concrete is remarkable when it is added into concrete, so the application of silica fume in concrete is very common. So, specifically, where does silicon powder add to concrete, where is its advantage? Silicon powder manufacturer for you analysis.1. The

In recent years, the sustained driving of macro economy has made the refractory industry of our country achieve the continuous growth of output value and output with the market demand vacancy to be filled. Compared with the active refractory market, the lack of technical innovation has undoubtedly b

1. The use and characteristics of micro carbon ferromanganeseThe product is not only suitable for low carbon alloy structural steel, especially for high-quality steel, but also can optimize alloy, improve the internal quality of steel and reduce the cost of steel-making alloy without changing the or

Here mainly refers to the resistance of coke itself. If the resistance of coke is small, the current through the charge is large, so that the electrode rises, and the insertion depth of the electrode is shallow. On the contrary, the resistance of coke is large, such as using gas coke, because of its
