Alloys Cored Wire is an intelligent alloying solution in secondary metallurgy. It can precisely control composition of metal during ladle treatment to produce ultra clean quality steel & efficient use of plant equipment. Our cored wire is characterized by a defined powder i.e. Deoxidant, dsulfurizer alloy encapsulated in steel sheath & gives a well-controlled weight & uniform distribution of powder per meter over entire length. INJECTION TECHNOLOGY: The wire Injection is carried out in full ladle either in a Ladle furnace, a Ladle station or Tundish, using a specially designed wire feeder. By using feeding machine the cored wire is injected into the bottom of ladle at desired speed. The powder will eventually get dispersed along with the melting of wire sheath and will react with the liquid steel. As a result the following treatments will be achieved: •Desulfurizing, deoxidizing & alloying. •Improving morphology of steel as well as the machinability. •Refining, to obtain clean steels with low oxygen and sulfur contents. •Avoid Nozzle clogging •Improving isotropic properties of steel. •Addition of alloying elements with precise trimming of the chemical composition of the steel

The three roll bending machine is considered to be the quickest, most precise and easiest to be operated bending machine.

One side roller can be used as the block to keep the work piece form a right angle which is parallel to the lower roller. The plate leveling operation is simple and three person is enough for operation.

After leveling the plate, the upper roller and the lower roller will clamp the plate. As a result the pre-bending and rolling is much easy and safe, no risk of slipping.

The cone rolling is much easy and the biggest angle is less than 30⁰. The working ability is one-third of the usual. The degree of dip of the side roller can decide the angle of cone. The lower roller also will dip to clamp and drive the work piece.

The REMSO Temperature, Oxygen, Carbon & Sampling Manipulator is mounted on support structure, which swivels from a parking position to the measuring position. The RTSM, provides the possibility to measure temperature and to take a sample by means of disposable cardboard Immersion Sampler.

Working Principle

The temperature measurement is an integral part of tracking progress throughout the tap-to-tap cycle in steel making. Expendable probes are also used for tracking bath carbon content and dissolved oxygen levels in the steel. These tools have enabled the tap-to-tap cycle to be accelerated by eliminating long waiting periods for lab results, thus increasing productivity. Disposable probes are typically mounted in cardboard sleeves that slide on to a steel probe (pole) which has internal electrical contacts. The disposable probe transmits an electrical signal to the steel pole, which in turn transmits the signal to an electronic unit for interpretation. Almost all probes rely on an accurate temperature measurement to precisely calculate carbon or oxygen levels.

The TSM from parking position to working / measuring position and back is fully automated. The complete system of RTSM and swiveling support can be supplemented by an Automatic Probe Changer with a magazine of lance tips. Which also break the SLAG and take the sample and temperature.

Pioneers in the industry, we offer torpedo ladle car and torpedo ladle heating station from India.

v  Removing and fixing of  the porous plug located on the bottom of steel ladle in hot condition.

v   Changing the inner cup of steel ladle in hot condition.

v  Stirring the liquid metal to mix alloying metals and fluxes perfectly.

v  Chiseling and removing the Slag and Dross built up on the furnace lining and furnace hearth, de

v  Mouth Jam Cleaning in hot conditions.

 

The furnace tending vehicle is equipped with under carriage mounted on crawler with flat shoes. The upper – structure is attached with a 2 section telescopic boom with various tending attachment shall be rigged for above mentioned operations

Gas stirring for homogenization of both, temperature and chemical composition during the treatment of the heat in the ladle furnace station is usually realized by gas purging through one or more porous plugs located in the ladle bottom. In case the ladle purging plug fails to open, the REMSO emergency top lance system can still save the heat.

 

REMSO design features:

 

• Lance carriage driven by chain / Rope system.
• Oxygen lance is guided by rollers and rails on the running faces of the guide cage.
• Oxygen Pipe is made of ASTM 312/321
• Lance is clamped to the carriage by clamping arrangement.
• A bracket fitted to the lance carriage serves for the connection of the oxygen and the water cooling system.
• Guide track is steel structure which guides the lance carriage
• Vertical swiveling column.
• Local or remote control.
• Magazine for stirring Lance Storage.
• Automatic start of gas flow when lowering the lance.
• Quick coupling for quick connection and disconnection.
• Collision interlock.

A.O.D. Convertor is installed near to the furnace. The desired scrap will be melted down in the Furnaces. The molten metal at temperature of 1580°-1600°C will be transferred to the A.O.D. Convertor Vessel via over head crane to refind to the desired chemical composition by addition of required Alloys/Fluxes and use of various gases. The gases media such as Oxygen. Nitrogen, Argon & Compressed Air are injected into A.O.D. Convertor through High Blowing rate Tuyers along with oxygen Top lance for good mixing effect and excellent Heat efficiency.

AOD,Argon Oxygen Decarburization, is a process for making stainless steel and other high grade alloys by allowing precise gas manipulation. Since stainless steels need to be further refined, oxygen, gradually replaced by argon, is blown through the molten steel to eliminate impurities.

This refining process produces steel with low carbon properties (.01% or lower) and low silicon levels, which, in turn, creates a metal that has better weldability (can reduce weld electrode use by over 50%), and is more corrosion resistant, malleable, and heat resistant.

Features:

• AOD is increasingly used to improve alloy performance.
• Control cost by capturing and reusing machine chips
• Recycling of raw materials with guaranteed high purity.

The vacuum oxygen decarburizer (VOD), an oxygen lance in the centre of the tank lid to enhance carbon removal under vacuum. The VOD is often used to lower the carbon content of high-alloy steels without also overoxidizing such oxidizable alloying elements as chromium. This is possible because, in the pressure-dependent carbon-oxygen reaction.
