    软门帘的组成与哪些因素有关系?

    软门帘由速度和软门帘组成,砂粒大小和熔化系统温度有关。
    The soft curtain consists of velocity and soft curtain, and the size of sand is related to the temperature of melting system.
    (1)软门帘组合。软门帘的组成与熔融有很大的关系。不同的软门帘组成在熔体的私密性和熔体的速度上各不相同。
    (1) combination of soft curtain. The composition of soft curtain is closely related to melting. The composition of different soft curtain is different in melt privacy and melt speed.
    软门帘在熔化过程中,由于协同材料的分化、部分组分的挥发、氧化物的氧化还原以及软门帘与耐火材料的相互作用,产生大量的气体。在此期间,炉内大部分气体逸出。在剩余气体中,部分气体溶解在软门帘中,部分气体以可见气泡的形式存在于软门帘中。可见气泡的存在,严重影响软门帘的质量,有必要进行清扫。在软帘产生能看到泡泡扫过的过程叫软帘弄清楚。弄清软门帘是软门帘融合系统进步的一个环节极为重要。软门帘的弄清触气在软门帘中的繁殖、起源与平衡,弄清机理与方法。

    In the melting process of soft curtain, a large number of gases are produced due to the differentiation of synergetic materials, volatilization of some components, oxidation-reduction of oxides and the interaction between soft curtain and refractories. During this period, most of the gas in the furnace escapes. In the residual gas, part of the gas dissolves in the soft curtain, and part of the gas exists in the soft curtain in the form of visible bubbles. It can be seen that the existence of bubbles seriously affects the quality of soft curtain, so it is necessary to clean it. In the soft curtain generation can see the process of bubble sweeping is called soft curtain clear. It is very important to make clear that the soft curtain is a link of the progress of the soft curtain fusion system. To understand the reproduction, origin and balance of air contact in soft curtain, and to understand the mechanism and method.

    一、软帘气
    I. soft curtain air
    如前所述,软幕中的气体主要来源于协同材料及其熔融,部分来源于软幕与耐火材料的相互作用。炉膛内气体的种类和数量取决于软门帘的组成、炉料的种类、炉膛内的气氛、压力和熔体等使炉温发生凹凸变化。常见气体有:CO, O?N H 0 CO H,对吧?不,是惰性气体。这些气体以三种方式存在于软门帘中,即可见气体(气泡)、物理溶解气体和化学合成气体(气体与软门帘组分响应)。软门帘的弄清楚的不是“去气”,而是“废气”,即软门帘弄清楚的不是拿出所有的气体,而是扫走“可见”气体的过程。从某种意义上说,这个过程是一个粗糙的流体力学过程,但它实际上包括一个混乱的物理化学过程。
    As mentioned before, the gas in the soft curtain mainly comes from the coordination material and its melting, and part of it comes from the interaction between the soft curtain and the refractory. The type and quantity of gas in the furnace depend on the composition of soft curtain, the type of charge, the atmosphere, pressure and melt in the furnace, which make the furnace temperature change unevenly. Common gases are: CO, O? N h 0 co h, right? No, it's inert gas. These gases exist in the soft curtain in three ways: visible gas (bubble), physically dissolved gas and chemically synthesized gas (gas and soft curtain component response). What the soft curtain makes clear is not "degassing", but "exhaust gas". That is to say, what the soft curtain makes clear is not to take out all the gas, but to sweep away the "visible" gas. In a sense, this process is a rough hydrodynamic process, but it actually includes a chaotic physical and chemical process.
    2. 明确过程中的气体平衡及转化
    2. Define the gas balance and transformation in the process
    在软门帘让融化过程中,气体的气体溶解气体在液体软门帘、泡沫和窑炉内气体,平衡3人之间的联系,这种平衡取决于气体在各个阶段中分压力很好,分压力的气体总是从一个阶段高阶段的分压力低。
    In the process of soft curtain melting, the gas dissolved gas in the liquid soft curtain, foam and gas in the furnace balance the relationship between the 3 people. This balance depends on the gas in each stage of the pressure is very good, the pressure of the gas is always from a stage of high stage of the low pressure.
    在澄清过程中,气体的平衡和转变随着不同熔化阶段的要求而不同。在此过程中,需要将溶解的气体尽可能多地转化为气泡,然后将这些可见气泡浮起并扫入炉内空间。在透明结束时,未清扫的小气泡溶解在软幕液中,使其看不见。这就是明确性的原则和意图。
    In the process of clarification, the equilibrium and transformation of gases vary with the requirements of different melting stages. In this process, the dissolved gas needs to be converted into bubbles as much as possible, and then these visible bubbles float and sweep into the furnace space. At the end of transparency, the small bubbles that are not cleaned are dissolved in the soft curtain liquid to make it invisible. This is the principle and intention of clarity.
