In steelmaking, slag-metal mixing is a very common phenomenon and it occurs due to the shear at the slag-metal interface caused by excessive liquid steel flow. 37 This mixing leads to emulsification of steel in slag, which increases the total interfacial area and consequently the rate of slag-metal reactions.

Interlocking is a method used to maintain safe operating state of machinery. Interlocks (except process) put the 'target device' (the equipment which the interlock acts on e.g Valve or Pump) into a "default" position to help ensure process is in a safe state. All interlocks report to the control system. Also Read: Shutdown Philosophy.

The liquid slag is tapped at temperatures around 1600 °C and allowed to slowly air-cool forming crystalline slag. Depending on the intended steel quality (carbon steel or stainless/high alloy steel), two different slag types can be generated: - EAF C: Electric arc furnace slag from carbon steel production - EAF S: Electric arc furnace slag ...

What is claimed is: 1. A method for reducing to metallic chromium the chromium oxides found in slag formed in an electric arc furnace during a stainless steel making process, which method comprises maintaining said slag in a liquid phase while at the same time blowing into said furnace, via a carrier gas, powdered aluminum dross in a thrown in amount which satisfies the equation: 0.5≦[Thrown ...

For HVAC chilled water system, can we have interlocking in the electrical panel for system start up sequence as below... IPS Receives $1.8 Million Order for Packaging Equipment The TMC 400 series has a welded tubular stainless steel frame with hinged Lexan cover panels and safety electrical interlocks .

Steel slag types and great wall slag services. The slag derived from stainless steel production presents particular challenges, it is owing to the handling of fines in its cooled state. Our great wall group will process Electric Arc Furnace (EAF) and Argon-Oxygen Decarburization (AOD) slag, from austenitic or ferritic grades of stainless steel.

D. Sichen, in Fundamentals of Metallurgy, 2005 9.5.1 Slag-metal mixing. In steelmaking, slag-metal mixing is a very common phenomenon and it occurs due to the shear at the slag-metal interface caused by excessive liquid steel flow. 37 This mixing leads to emulsification of steel in slag, which increases the total interfacial area and consequently the rate of slag-metal reactions.

Sentry's simple and expandable interlock modules control 2 - 10 doors - all interlocked. Sentry offers "stand alone" modules as well as a variety of expansion modules for automatic doors, access-controlled doors, roll up doors and pass throughs. We also offer units with adjustable, built in timers. All Sentry modules are easily ...

Step 1. A. Washdown, Cleaning, Sanitized Environment(Often food & beverage production) B. Dirty, Dusty or an Environment with Debris(A heavy duty environment) C. Extreme Enviroment e.g Cold, Hot or Corrosive(<-25 deg; >80 deg; Near salt water...) D. Explosive Environment(Where dust or gas could cause an explosion) E.

The slag derived from stainless steel production presents particular challenges, harsco will process electric arc furnace.Slag vertical roller mills, suitable for use on the slag production line with production capacities of 300,000ty, 600,000ty, and 1million ty.And part steel products received from the producing mill

by Editorial Staff. Protective tripping systems provide a defence against excursions beyond the safe operating limits by detecting a excursions beyond set points related to the safe operating limits (i.e. the onset of a hazard) and taking timely action to maintain or restore the equipment under control to a safe state.

Actuators are the final control elements or systems and include contactors and the electrical apparatus under control, valves (control and isolation), including pilots valves, valve actuators and positioners, power supplies and utilities which are required for the actuator to perform its safety function, all of which should be adequately reliable.

Jan 24, 2020· A new synergistic treatment of stainless steel slag and low zinc content electric arc furnace (EAF) dusts is proposed to immobilize harmful chromium in stainless steel slag. The effects of ZnFe2O4 addition on the mineralogic phase and chromium leachability of CaO-SiO2-MgO-Al2O3-Cr2O3 synthetic slag were investigated to explore ...

George C. Wang, in The Utilization of Slag in Civil Infrastructure Construction, 2016 10.5.3 Reclaimed asphalt pavement containing slag aggregate. Recent research found that some steel slag aggregates in RAP, with 92% steel slag aggregates, showed considerably high expansion potential, up to 6.2% swell.

Process Interlocking 6 A process interlocking example: chemical dosing Closed re-circulating water systems (heating or cooling water) need to be dosed with chemicals on a regular basis; this can be done by using a dosing pot. To prevent the operator from any contact with the potentially dangerous process flow, valve interlocks

To remove the slag, NEE used its proprietary two-step cleaning process followed by electropolishing (EP) to debur the parts and leave a smooth finish. As part of the process, we had to ensure the EP racks and clips we used didn't leave marks or damage the design features of the part. To meet the customer's request for a non-shiny finish ...

Interlock System SAFETY IS CRITICAL. In various process plants, refineries, Power plants, steel plants, tank farms, offshore oil and gas installations etc. where hazardous operations are being done continuously, the design engineering for such works is done in e way that critical operations are carried out with correct sequence and safety procedures.

Netherlocks has developed process interlocking solutions for various applications such as pressure relief valves ( PSV, pig launching and receiving, inert gas systems, pump start up, flare lines, boiler blow-down, ' 2 out of 3 ' and decoking. "Netherlocks has supplied manual valve interlocks for many of our FPSO's. They provided ...

the design of a key interlock system must address:-Where such valves are part of an ESD system, the key interlock system must not compromise the valve's fail-safe function. Where pigging operations occur, the key interlock system must verify the valve's absolute position (open and/or closed) independent of any on-board instrument indication.

The operation of the mechanical interlocking is achieved by the lever frames which are connected by the wire to the signals and points. This type of interlocking is composed of locking frames, plungers, lock bars, etc. So the lever movement is the major process of this interlocking and certain steps of this interlocking will be done manually.
