In order to improve slag ball against thermal shock performance, improve the efficiency of high-quality energy-efficient slag slag ball, has developed a calcareous slag ball. First in the core layer of refractory fibers outsourcing for dampening effect; ball shell with dolomite, lime, etc. for raw materials, such as synthetic resin or pitch as a bonding agent for manufacturing. The key success slag ball method: First, the density of the ball properly, that is 4.3 ~ 4.4g / cm3; the second is taphole safeguard energy-slag ball, keep the round; the third is where to place the ball on the quasi-tapping hole. However, due to slag ball shape, easy to follow the flow of steel float and leave the tap hole, thus losing the role of slag. Slag tapping: to ladle (ladle) within released after the end of the converter blowing or arc furnace smelting complete oxidation of molten steel and the oxidation furnace slag to remain in operation. So that when the slag and molten steel oxidation separation is refining requirements. Secondary refining ladle adapted to be carried out under reducing conditions. Using a steel slag, steel slag to avoid an increase refining effect is an important guarantee. When the energy-saving steel slag ball price, with the decline in the steel surface when molten depths below a certain critical value, at the top of the tap hole will form a funnel-shaped vortex confluence partly molten slag before the finish on the taphole outflow, which is the root cause of the slag, steel separation unclear. Buying energy-slag ball, Sichuan energy-slag ball, metallurgy Wing Wing by Anyang metallurgical Refractories Co., Ltd. Anyang City Wing-metallurgical Refractories Co., Ltd. (www.ytyj888.com) strong, credible, and other industries in other Anyang accumulated a large number of loyal customers. The company better work attitude and continuous improvement through innovative ideas will lead metallurgy and you work forever into the brilliant, for a better future!
