compare the application effect of solid cored pure calcium wire and silicon calcium wire

  There are many types of cored wires, and different cored wires have different characteristics and can be used in different fields. Both solid-core pure calcium wire and silicon-calcium wire are cored wires, and the difference between the two can also be found by comparison. In order to make everyone more intuitive and clearly understand the solid-core pure calcium wire and silicon-calcium wire, I will briefly talk about the application effects of solid-core pure calcium wire and silicon-calcium wire. Under the condition that other processes and raw and auxiliary materials in the front of the furnace and the refining furnace remain unchanged, the solid-core pure calcium wire is used to replace the silicon-calcium wire for calcium treatment.

 

      The solid-core pure calcium wire is more intense than the molten steel reaction compared to the silicon-calcium wire. Pay attention to the calcium treatment operations, such as the feeding depth and feeding speed. During the thread feeding operation, the solid-core pure calcium thread has a high calcium vapor pressure. In order to prevent the natural evaporation of calcium, the solid-core pure calcium thread must be fed deep. One way is to increase the thickness of the iron sheet to prevent its premature melting from affecting the calcium release depth; the other method is to increase the feeding speed to increase the calcium release depth. The higher feeding speed allows the solid pure calcium wire to penetrate The slag layer reaches a certain depth, reduces the oxidation of calcium by the slag, increases the absorption of calcium by molten steel, and improves the recovery rate of calcium.

  Generally speaking, wire feeding speed and wire feeding rhythm are the key parameters of the silicon-calcium wire feeding process. Too fast or too slow wire feeding speed and rhythm will affect the melting time and oxidation degree of the silicon-calcium wire, resulting in metallurgy The effect is affected. Therefore, when applying the silicon-calcium wire, you must always pay attention to the molten steel. Once the molten steel rolls violently, you must stop for a while before continuing to feed the wire to prevent splashing.
