Lime: lime quality requirements. Many detection methods for quality or degree of activity of the active lime. Among them, often with hydrochloric acid-based titration. And during calcination Shandong steel with lime, using hydration contrast method, hydration weighing method and sampling method to determine Henan steel knock like lime, analysis calcined lime quality is relatively quick and practical. Lime: limestone itself there by raw materials, the impact and the sulfur content of the fuel itself calcination factor Steelmaking lime sales generated by the limestone lime itself will contain different levels of sulfur, phosphorus and other elements, to this end, lime itself sulfur, low phosphorus content is required. And its former limestone (raw material) and low parathion is also a low content of the fuel requirements.
