What is Slag Cement. Slag cement is a hydraulic cement formed when granulated blast furnace slag (GGBFS) is ground to suitable fineness and is used to replace a portion of portland cement. It is a recovered industrial by-product of an iron blast furnace. Molten slag diverted from the iron blast furnace is rapidly chilled, producing glassy ...
Ground granulated blast-furnace slag, more commonly referred to as slag or slag cement, is a by-product of steel production. Slag is primarily composed of CaO, SiO 2, aluminum oxide (Al 2 O 3 ), and magnesium oxide (MgO). When used as part of a portland cement concrete, slag reacts with both the water (latent hydraulic reaction) and the ...

Manufacturer of Synthetic Slag - Ladle Additive For Gas Remover, Slag Conditioner Powder ALOXE ALMIX, Almix Slag Conditioner Powder and LDSF Synthetic Slag Powder offered by Guru Corporation, Ahmedabad, Gujarat. ... The application of ladle slag detection system can reduce the happening of nozzle clogging.
This means that by quantifying the amount of fine particles produced under an accelerating condi- tion (powdering rate), the rate of slag particles that imply the possibility of causing expansion crack can be assessed (Fig. 1).
Slag detection triggers an alarm signal, which is used to control the slide gate. The effectiveness of the slag detection algorithm enables early detection of slag presence and time-effective closure of the slide gate, minimizing slag transfer e increasing ladle yield. Furthermore, the ISD system eliminates the need for human presence in the hazardous area close to the ladle,

Ground Penetrating Radar FAQ. How does GPR Work? Every GPR system contains one or more antennas that transmit and receive radio frequency waves. These radio waves penetrate the surface that the antenna is touching or in close proximity to. While much of the signal dissipates, a percentage of the signal comes back to be received by the antenna.
