We all know that metallurgical steel making slag can not be separated from active lime,and the requirements for active lime for steel making are also relatively strict,not only for good activity,but also for specifications to meet the requirements.Once these conditions can meet ,your active lime price will certainly meet your requirements,as the saying goes,a good one-cent price,it’s truly.
Requirements for active lime in metallurgical steelmaking plants:
1. Particle size is one of the most strict requirements for the manufacturers of the active lime kiln production line in the steelmaking plant. The size of the active lime particle will affect the reaction rate of slag formation and the efficiency of steelmaking directly. So this is basically hard conditions for particles to generally be allowed to be 5 millimeters to 40 millimeters, but steel mills still like 5 millimeters of active lime, because the smaller the particles are, the more efficient they are. It can also improve the quality of steelmaking very well, which is similar to the fact that we could not make good iron and steel in the 1980s. A large part of the factor is that we did not have the high quality active lime calcined in rotary kilns at that time, and we used vertical kilns to underburn the lime. Overburning to avoid bad control, so to refine the iron man must start with good active lime.
2.The activity degree is an important standard of slag formation and reaction speed in steelmaking, so many new suppliers can not avoid the detection of active lime when they buy active lime.
Generally, water solubility detection is the ability to react with water. Active lime reacts with water to release heat, and the heating time of water is less than 10 minutes. In addition, the consumption of 4NHC can also be used to detect. When the fixed 4NHC completely reacted with the active lime within 5 minutes, the activity degree of the active lime was greater than 300ml.
Although active lime is widely used, the purchase price of active lime in the steel industry is still very substantial. So please do not be afraid of the strict requirements of metallurgical steelmaking plants. As long as there are data requirements, we can achieve activity greater than 300ml, particles in about 5 mm, porosity greater than 40%, volume density less than 0.666g/cm, etc., our Tongjia industry is for you to build an active lime kiln production line. We have professional designs and engineers, so please trust us.
