Many times, when customers buy steel rods for rod mills, especially at the beginning, they do not know what kind of steel rods to buy. They ask the rod mill manufacturers, because the rod mills produced by some rod mill manufacturers do not Too many, I don't know much about the steel bar, and I can't give a pertinent suggestion. What's more, casually say "No. 45 round steel" and "65Mn round steel", thus causing the customer's upfront cost. There is no need to waste, the steel rod bends, breaks, and wears quickly after the steel rod is put in... It is miserable. There are many such lessons. In fact, it is very simple. How to choose and how to maximize the input-output ratio.
After purchasing the steel rods of the rod mill with reasonable technical parameters, how to use them is another question. As mentioned above, many customers just put them in and don't care. The steel rods are always kept in the mill for initial grinding. The ratio of steel rods is ideal, but due to wear and tear everywhere, when to draw rods? When to add the stick? What kind of stick can continue to use? Failure to study these will result in a second waste of cost. Today, there are several principles in the web link for your reference, which may not be comprehensive. Welcome to add in the comments:
1. See the fineness of the material: if the ratio of steel rods is reasonable, a reasonable fineness will be obtained. When the fineness of the discharge is too small, add thick rods appropriately, and add thin rods when it is too large; if the fineness of the discharge is just beginning It meets the requirements, but it is uneven afterwards. It may be that there is a problem with the internal ratio of the steel rod. It is not that the initial ratio is wrong, but that the steel rods with different diameters wear different speeds during the grinding process. The reason for this is generally due to the large difference in the technical standards used for steel bars of different diameters; another reason is that the bending of some steel bars disturbs the normal operation of the steel bars, resulting in insufficient grinding. In the case of the above situation, you should stop the machine to sort the steel bars, take out the thin bars (generally recommend to draw the bars when the diameter is 40mm), and add qualified large-diameter steel bars before running.
2. Look at the output: Under the condition that the processing capacity remains unchanged, if the output drops sharply, it is necessary to consider whether the steel rods inside the rod mill are sufficient. I mean that although the steel rods are added on time, because the rods are not drawn in time, The thin rod can no longer function as a "rod" in the rod mill, but is equivalent to a "stubborn stone". When it is thin enough, it will either become a twisted roll or break into sections, which is very important to the output. have a great influence.3. Listen to the sound: The sound of normal steel rods running in the mill is relatively dull. If there are broken rods or bent rods, if you listen carefully, you will hear a relatively crisp impact sound. It is not caused by stubborn stones or rods. Timely stop grinding and inspection can avoid greater losses in the later period.
Some customers do not pump rods in order to save costs, and some customers pump too early for the normal operation of the rod mill. One saves labor costs and steel rod costs but affects the output, and one does not affect the output but increases labor and steel rod costs. , I really can't do anything if I don't want to draw sticks. It is said that "workers don't want to go in and smoke." I know the pain of drawing sticks, so I understand.
