Q1.what is the test principle and the reactivity?

Test principle: firstly, hydrate a certain amount of lime and at the same time, with a certain concentration of hydrochloric acid neutralize calcium hydroxide which produced during the lime hydration process. From the beginning to the end, always in a state of agitation speed, the water temperature is keep 40+-1℃ and keep in the process of neutralization equivalent points. Accurate records the consumption of hydrochloric acid when at 10minutes

The reactivity: the number recorded is called lime reactivity.

Q2.What is the importance of lime reactivity?

Lime quality had a great influence on steelmaking process, and its performance is good or bad, directly related to the smelting time, smelting speed, the quality of the steel, steel scrap ratio and heat energy utilization coefficient and other indexes. In the metallurgical industry, refers to the activity of lime degrees it reactions with other substances in the slag. With lime in the slag melting rate. Thus test the characteristics of quick lime is one of the important projects of metallurgical experiments.

Q3.What the advantages of this product compare to manual measurement ?

The manual measurement widely used at present domestic lime activity, the standardization, including of human factors is more, lead to the determination results is not accurate, efficiency is low. And contact with acid fog, there will be a certain risk, this product can be a very good one to solve the above problems.

Q4.What is the practical significance of the lime reactivity ?

Steelmaking practice shows that active lime can improve 80% efficiency of dephosphorization and desulphurization, shortening time of smelting and at the same time within 3-5 min can completely reaction with acid in the liquid steel, and general lime reaction time must be at least 6-10 min. Also, furnace life can be extent by more than 40%, moreover, furnace burden of consumption also reduce 5-8 kg/t steel, with 10 million t calculate, save $15 million a year, the production efficiency is improved significantly.
