Mill Scale Binder for Briquettes

Mill scale is a by-product produced by steel making and rolling, and is a scale that falls off the iron when practicing steel cold extraction. It is an oxide of iron, mainly iron oxide and ferrous oxide, with an iron content of about 70%.

There are two ways to use mill scale in steel mills: one is as an auxiliary material applied to sintering, and the other is to supply mill scale directly to steelmaking after briquetting as a slagging agent, which has the function of slag removal, temperature regulation and reducing the cost of steelmaking.

When iron smelting, there will be a layer of slag on the surface of the?molten?iron, if it is too thick, it will easily the molten iron to splash. At this time, some slagging agent?should be thrown into it , such as iron?briquettes, iron blocks, fluorite briquettes, calcium oxide, etc., to cool down, create slag, and to break through the slag layer for ventilation.

Mill scale briquettes?have hardness standard before entering the furnace, the purpose is to avoid dropping powder when feeding from the perspective of smelting furnace.

In China,?mill scale briquettes?are?added to the converter, which has?a strong effect of slag melting and temperature regulation. Some steel mills also mixed with magnetically separated steel slag powder for briquetting,and a small amount of steel slag powder is added to sinter, which also reduces the amount of phosphorus in blast furnace hot metal, optimizes raw material conditions, facilitates operation, improves technical indicators and reduces costs.

The mill?scale?binder developed by Sichuan Jianjie Composite Materials Co., Ltd. has the following characteristics:

1.?Low dosage, high viscosity, high forming rate.

2.?No increase in ash, no reduction in grade, no increase in phosphorus and sulfur.

3.?The operation is simple, just mix the raw material and the binder evenly, add water and stir evenly, and then enter the ball press machine( briquettes machine).

4.?The wet strength is 2 meters, it will not break or disperse, the dry briquettes strength is more than 100 KG, and the drying breakage rate is low.
