Iron mill scale prices are currently being traded depending on the quality of the load in the range of 170 to 250,000 tomans per tonne. We determine iron mill scale prices by examining several cargo features. The first is the percentage of iron purity in the iron mill scale, the second is the ratio of oxide shell fines and grains compared to the amount of pigment shell coins. Depending on the application of the iron mill scale, other specifications such as the thickness of the patches, the coarser size of the patches, etc., also matter.
iron oxide mill scale
Iron mill scale are fragments of steel ingot during hot rolling of this product and the production of the final steel sections. Also, in steel slab correction units, the percentage of iron entering the line is eliminated as waste iron scale. Wasting a percentage of the iron charged on hot rolling lines and refining slabs increases production costs and reduces efficiency. The percentage of iron extracted from the production lines as an iron mill scale and the productivity of these units is estimated at about two percent, which in turn is a significant percentage.
Are there any methods or conditions to get the iron oxide mill scale back to the steel lines? Is there an iron mill scale used in the industry at all, or is it separated from production lines as waste?
Iron mill scale analysis
As can be seen, the percentage of iron present in the iron mill scale is often over seventy percent. This shows the usability and return of this product to the production and steel lines. How can iron mill scale be returned to steel plants? Is this done right now?
Iron mill scale buy
The iron mill scale buy is aimed at using it in various sectors of the industry. Here are the following:
Iron mill scale buy for use in steel units
Iron mill scale Due to its high iron content above 70%, it can be recovered in the steel chain using melting furnaces. The melting furnaces of the steel units are of three types, the long furnace, the induction furnace and the arc furnace. Use in blast furnaces for melting iron mill scale is possible. The use of this product for induction and electric arc furnaces should be handled with caution and, of course, with the quality control of each factory’s quality control unit.
The iron mill scale used to melt and return to the steelmaking process is examined in terms of grade and percentage of iron. However, due to the removal of impurities in the furnace during melting, the percentage of annoying elements in the shell is also very important. So what’s important in selling iron mill scale to smelters is its analysis and purity. But there is another important and happy point. And that is the use of this product and factory waste in other parts of the industry. In the following article, we will address three of these applications.
Iron mill scale sale as melting aid
Iron mill scale is also used in the ferrous metal industry. This product is used in mills as melting aid.
Iron mill scale is used by companies and factories as a smelter. In the use of Iron mill scale as a smelter in the industry, too, product analysis is often important, and the physical characteristics of the cargo are of little interest to the buyer. Factories even make iron mill scale buys, which are fine-grained mixes.
You can see an example of this cargo Iron mill scal in the video below.
Iron mill scale price for aggregation
As we have said, Iron mill scale has fortunately gained many applications in many industries. Some factories first apply the product to the process of processing and aggregation and then use it for their intended use.
In such applications, the high purity of the product and the low percentage of fines and soils within the product are very important. Iron mill scale shipments must have a high percentage of coins. Iron mill scale shipments of Phoenix Steel Company of Azerbaijan with a very low percentage of fines (90 to 95 percent of confetti and 5 to 10% fines) you saw in the video vignette.
Of course, in these types of cargoes, in addition to the percentage of Iron mill scale, the thickness of the cargo is also important because the Iron mill scale is used for grain size. Therefore, it needs to be of a suitable thickness for aggregation.
Iron mill scale processing and screening
Iron mill scale collectors often request products from various industries to suit their needs and specifications purchased for Iron mill scale cargoes, often after delivering the cargoes to their warehouse. They process. The processing process performed on the Iron Mill scale in the workshop is the Iron Mill scale sifting process. During this stage of processing, the iron mill scale scale is separated from the iron mill scale fines.
The process of screening Iron mill scale by workshop workers can be seen in the video below.
Iron mill scale for the production of ferrosilicon
Other major applications of the Iron mill scale can be used in the ferrous silicon industry. Ferrosilices are in the group of metal alloys whose main constituents are iron and silica. In the Iron Mill scale analysis table above, as you can see, iron and silicon have the highest percentage of elements in the Iron mill scale composition. The ratio of silicon and iron in ferrosilicon varies between 15 and 90%.
Ferrosilicon has many uses.
- One of the applications of ferrosilicon is in the steel industry. Ferrosilis is used in the steel industry as a sprayer and, of course, as a source of silicon in the production of silicon alloy steel.
- During the thawing and casting process, ferrosilicon is added to the melt as a germinator. Germinators are the place where germination of steel grains during cooling. The presence of germs in the melt causes the steel structure to be fine-grained. As we know, fine-grained steel has better mechanical properties both in terms of strength and flexibility.
- The presence of silica in the melt reduces the metals in the melt so it can also be used to prevent oxidation of steel. In fact, this product is used in the production of corrosion-resistant steel.
- Another use of ferro-silicon is the use of this product and product in the production of ferro-silica. Ferrosilis is used in the production of malleable iron.
- Ferrosilis is also used in cast iron production. The use of this product in casting is to prevent the formation of carbide and encourage the formation of graphite precipitate in a spherical form.
- And …
We have mentioned various applications of ferrosilicon in this section of the article.
Iron mill scale is a very important product in the production of ferrosilicon. Although the iron mill scale is thrown away by a percentage of iron from hot rolling lines and modified to a flat mill, the efficiency of production in these units is reduced, but fortunately, the use of iron mill scale can greatly reduce energy loss.
As mentioned above, the specifications of the iron mill scale are considered according to its application. The iron mill scale used to produce ferrosilicon is also traded precisely on the basis of load analysis.
Iron mill scale suppliers
The applications we mentioned in the paragraphs above are a limited number of iron mill scale applications in industries. There are different applications in different industries for this product. Of course, in addition to domestic consumption, there is a significant annual volume of iron mill scale sales in the export sector. The major iron mill scale exports to China.
Iron mill scale hs code
Iron mill scale or steel ingot shell is traded under HS Code Codes 26190090. Iron mill scale trading and international trade statistics are recorded in the customs of the buyer and seller countries according to this code.
Trading iron mill scale
Iron mill scale pricing As mentioned at the beginning of this article, it is highly dependent on the quality of Iron Mill scale shipments. Whether or not the quality of Iron Mill scale shipments is the best quality depends entirely on the type of product used. (This is briefly mentioned in the description section of the Iron mill scale applications for each use.)
In most cases, if the processing is carried out to mesh the Iron Mill scale, or the sieve is removed to remove the fines and dirt of the product, then due to the processing costs and manpower hired to do so, the Iron Mill scale price rate (Steel ingot shell price) will be higher. Currently, the price of Iron Mill scale depends on the quality of cargoes ranging from 170 to 280 thousand tomans per ton.
To register an Iron Mill scale purchase order, you need to inform your sales department about the type of use you have or the quality you want to detail in order to process the best quality based on your type of use and make you a respectable buyer.
