LAG-S400 Infrared Converter Slag Detection System
Overview
The infrared converter slag detection system uses a far-infrared thermal imager to monitor the situation of converter tapping in real time, and is connected to the main control computer in the electrical room through the conversion and transmission of video signals. The radiation intensity in the infrared wavelength range of 7-14um is different to distinguish molten steel and slag. In the later stage of the converter tapping, the molten steel gradually decreases, and the steelmaking slag is involved in the molten steel and flows out of the tapping hole. After the thermal imager recognizes the steelmaking slag in the imaging temperature measurement, it will give an alarm according to the slag content ratio threshold set by the software. The thermal imager will start the slide plate to close the tapping hole, so as to realize the control of the slag in the converter tapping, and ensure the maximum yield of molten steel and the minimum control of the steelmaking slag content.
The effect of slag detection in converter tapping is of great significance to the control effect of the slag amount. The converter slag detection and control system developed by our company conducts non-contact monitoring of the tapping steel flow through the far-infrared detector thermal imager. It can detect the slag condition in real time and output an alarm signal and control system, which can replace manual visual inspection and provide accurate, efficient and stable slag detection effect. When the system finds the slag, the intelligent control unit quickly makes a judgment of lifting the furnace and blocking the slag and outputs an alarm signal.
As shown in Figure 1, the system includes thermal imager, front purge protection box, front electrical box, power distribution cabinet, main control monitor, monitor of rocking furnace chamber, sound and light alarm, infrared converter slag monitoring software system, etc.

We are proposing about 1000 1200 Mt/ton monthly of iron slag derived from the desulphurisation skimming process. This material is a iron by- product that is encapsulated in varying levels of contaminants (S,Mg,Si). In order to enhance its usability, the material is processed and screened. We can propose two specifications of Iron Slag : 1. >85% Fe Average 600mm Max Fraction 2. >78% Fe Average 20-300mm Fraction The level of Fe% in the slag has been estimated by water displacement test. For any further information please feel free to contact

Desulphurisation Slag is an iron slag derived from the desulphurisation skimming process. This material is an iron by- product that is encapsulated in varying levels of contaminants (S,Mg,Si), but has a stable chemistry with 75 -80% chemistry. The level of Fe% in the slag has been estimated by water displacement test. This material con offer competitive advantages respect other metal scraps: Price; Stable Chemistry; The material can be loaded loose in 20 heavy duty container. For further details feel free to contact us.
This Cast Iron slag is a by-product derived from the production of thermal insulating products. The byproduct is a ferrous slag which can be utilised in an electric arc furnace to produce crude steel. Physical Description On visual inspection, it appears to be made up of irregular shapes. Dimension: 500mm -800mm Chemical Composition Its chemical composition is homogeneous and stable with Fe contents in the range of 90 +/- 5% and P contents < 0.6% S around 0.15% and C% around 3.5%. Packing: Loose in container Loading: in 20 Container For further information, please feel free to contact us.

We are supplier and exporter of Copper Slag. Copper slag is a low cost expendable abrasive suited for open blast cleaning and due to its low silica content it does not pose the health hazards created by silica sand. Its sharp, hard particles can provide a fast cleaning action and an excellent surface profile. It is available in various sizes Copper slag is abrasive blasting grit made of granulated slag from metal smelting processes (also called iron silicate). Copper slag abrasive is suitable for blast cleaning of steel and stone/concrete surfaces, removal of mill scale, rust, old paint, dirt etc. Suitable for SA-3, SA-2 and SA-2. Copper slag blasting media/grit is manufactured of the granulated slag of copper refineries, and used for blast-cleaning of metal surface. In different industries it is called different names abrasive powder, grit, copper slag grit, mineral grit, grinding grains, etc.
