#118 - Tenova Also Makes Marine Leisure Products



We were surprised to recently learn about this interesting nuance of our company. The Tenova Group is a technology supplier to the mining & minerals and iron & steel industries. These are heavy industries. However, we also have a group that makes walkway & platform systems for marine leisure applications.

Tenova Takraf manufactures the largest vehicles on earth. See this link.

Tenova TAKRAF is also now the sole distributor of the Jetfloat Modular System in southern Africa. The Jetfloat system was designed and patented through extensive research and development by Jetfloat International in Austria. Comprised of modular elements linked together to form the required shapes, Jetfloat platforms are quick to assemble on land and on water and are easily extendable. The Jetfloat system is a modular pontoon and marine docking system.

BENEFITS
■ No repair and maintenance costs.
■ Light-weight and easy to assemble without the need for cranes.
■ Easily extended or altered in steps of 500 mm.
■ No sharp edges, corners or connecting parts, making the product safe for all environments.
■ Various anchoring methods make it possible to use this system in many applications.
■ Secure handrail mounting, which can be supplied to specification.
■ Other accessories available for a versatile hassle-free installation.
■ High elastic resistance to impact by boats, wind and storms.
■ Long life, as they are fatigue and weather proof and resistant to saltwater, chemicals and acid.




The flexible and long-lasting Jetfloat modular pontoons and systems make ideal marinas, bathing jetties, bathing islands, floating pools, diving platforms, event platforms, self propelling rafts and aquaparks, which blend in harmoniously with their natural surroundings.

FEATURES
■ Single layered systems have buoyancy of 350 kg/m2.
■ Double and triple layered systems available for supporting heavier tonnage.
■ Wave and storm-proof – employable off-shore, with the correct anchoring system.
■ Resistant to UV rays, salt water and various other chemicals.
■ Resistant to weathering

#117 - Earth Day - April 22, 2013

The Face of Climate Change is the theme of this year’s Earth Day.

Because we are a company that is interested in gas and atmosphere analysis, our blog has frequently discussed aspects of climate change, or equipment that helps reduce environmental impact of industrial processes. Sometimes we just ramble about things that interest us or bug us.

For example:

Here is a link to reversing the negative affects of environmental damage. Just kidding. Clicking and ‘liking’ on its own is not the same as environmentally responsible living.

#116 - Interesting comparison of Louisiana shore-line between the years 1932 & 2011

We saw this picture recently prepared by NOAA. Here's a link to the story.

The water isn’t lapping up at everyone’s doorstep. But that does not appear to mean that the levels aren’t rising.




Reduction of wetlands though development or through submersion no doubt further exacerbates these kinds of situations by removing the natural defenses. What will this shoreline look like in another 80years? Or perhaps a better question is: how far north will the shoreline be by then?

Louisiana is on our minds lately because Tenova HYL and Nova are involved in a couple of gas analysis projects there. Here are some pictures of one of those projects.

#115 - EAF Process Flow and the Tenova Group


The Steel Manufacturers Association (SMA) has released its Public Policy Statement for 2013-2014. The SMA is the primary trade association for scrap-based electric arc furnace (EAF) steelmakers.

Tenova Core and Tenova Goodfellow are both associate member companies in the SMA. Tenova Core also has a representative on the 2013 Associate Member Executive Committee.

EAF steel producers are the largest recyclers in North America. Over 90 percent of the material input to EAFs is recycled ferrous scrap. EAFs also play a large role in conserving energy – steel produced from melted scrap consumes approximately one third the energy that steel produced from iron ore consumes.

The production share of EAF furnaces of total steel production has grown from approximately 35% in 1990 to 60% in 2012.


In the back of the print copy of the Public Policy Statement, there is a nice diagram of the EAF process flow. This simple graphic prompted me to compare the standard EAF process with the expertise and products that can be found within the Tenova Group. Many of the areas do have a match. My summary of the Tenova capability is no doubt incomplete, but this is a good start.

__________

Steel Scrap Handling


Scrap steel has a high weight per volume and requires energy to receive and move around. Scrap steel is usually not received in geometrically and compositionally homogenous states. Material handling is therefore an important part of the EAF input process. I wasn’t able to find a direct match in the Tenova Group to steel scrap materials handling. However, Tenova Takraf is a world leader in materials handling for ore and mining applications. They may have equipment in their product line that is suited for steel yard and scrap handling.

__________

Electric Arc Furnace


This is the heart of the EAF process where the input material is melted down by electric arc. There are several areas of the Tenova Group that have a high relevance to the EAF.
  • Tenova Melt Shops manufactures electric arc furnaces. Tagliaferri is the historical brand of Tenova Melt Shops which has been designing and manufacturing EAFs since the very beginning of electrometallurgy.
  • Consteel is a continuous metallic charge feeding and preheating system made by Tenova Melt Shops.
  • EFSOP is an off-gas based process control technology produced by Tenova Goodfellow for energy optimization of electric arc furnaces.
  • The KT Injection System is a wall-mounted, multi-point system for injecting oxygen and a wide range of fines of carbon, lime, DRI and other materials into the slag layer of an EAF.

__________

Ladle Metallurgy Station


After tapping the molten steel, the ladle metallurgy station fulfills several functions in preparing the melt to be processed in the continuous casting machine. Ladle furnaces also act as a buffer between the EAF and continuous casting line. Tenova Melt Shops offers complete ladle furnace packages.

Tenova Melt Shops offers complete ladle furnace packages including:
  • Electric power supply
  • Ladles
  • Ladle transfer cars
  • Additives charging and injections systems
  • Dedusting
  • Electrode make-up stations and other auxiliary equipment

__________

Caster


Continuous casting is the process by which the molten metal is cooled and solidified into heavy steel strips called billets, blooms, or slabs. The produced steel may be stored or immediately rolled into finished products. There does not appear to be a Tenova company that makes continuous casters.

__________

Rolling Mill


Rolling mills further process the slabs and strips into other semi-finished products such as bars, billets, beams, or wire. The Tenova Rolling & Finishing division manufactures all kinds of strip processing lines and cold rolling mills.
  • Tenova Key Technologies - acid regeneration, iron oxide production, waste water treatment
  • Tenova I2S - cold roll mills
  • Tenova Presind Automation - integrated control systems and drives for processing lines and cold mills
  • Tenova Multiform - strip processing line and cold rolling mills in the Indian and Asian markets including India, Bangladesh, Vietnam and Indonesia.
  • Tenova Pomini - worldwide leader in production of roll grinders, for rolls belonging to flat products mills (steel and non-ferrous metals such as copper, aluminum) as well as paper mills.

__________

Finishing and Shipping


Further processing into finished products may follow the rolling mill or be integrated in with it. Inventory systems are used to store and stage the finished products prior to delivery.
  • Tenova Strip Processing – pickling, tinning, galvanizing, color-coating, silicon steel, stainless steel lines, and many others

__________

The Tenova Group is an intelligently diversified company that covers many areas of the steel-making process. The expertise accumulated among the Tenova companies is available to steel-makers around the globe.

NOVA Analytical Systems plays a small role in this value chain by manufacturing gas analysis equipment for a wide range of industries.
