Ahead of winter, Chinese steel mills rush to meet stricter smog rules (US)

BEIJING (Reuters) – Steel mills in Tangshan, China’s top steelmaking city, are rushing to install equipment to meet new ‘ultra-low’ emissions targets by an Oct. 31 deadline, as the measures to battle pollution threaten more upheaval in the debt-laden sector. Only a handful of mills have installed the technology that removes sulfur, nitrogen and dust and costs up to 200 million yuan ($29 million), according to analysts who have tracked the more than 150 sintering plants in the city affected by the new rules, which were only announced in July. “Everyone is trying to speed up the (upgrade) project … Still, time is very tight,” said an environmental manager at Hebei Donghai Special Steel Co, aContinue reading

Aug. 23 (UPI) — Material scientists have for the first time captured 3D images of crack formation in real time. The breakthrough allowed scientists to better understand how microscopic fractures propagate. The research could allow Continue reading

US Air Force Cancels $419.6 million Forgings Contract Awarded to Swiss Group: Schmolz + Bickenbach (US)

The US Air Force (USAF) has cancelled one of two contracts recently awarded to manufacture BLU-137/B penetrator warheads because the recipient is foreign-owned and so ineligible, Jane’s has learnt. Documents seen by Jane’s on 6 September show that the USAF has rescinded a USD419.6 million deal for 300 BLU-137/B ‘bunker buster’ bodies (with the potential for up to 3,500 bodies) awarded to Finkl & Sons Company on 27 June, as the Chicago-based steel manufacturer is owned by Swiss group Schmolz + Bickenbach.

The Air Force plans to scrap a contract worth hundreds of millions of dollars to make bunker-busting bombs amid lawmaker complaints it had been given to a foreign-owned company with ties to a U.S-sanctioned Russian oligarch. In an Aug. 30 letter obtained by Bloomberg Government, the Air Force appeared to agree with the lawmakers, who had said the company, Chicago-based A. Finkl & Sons Co., should have been ineligible because of its foreign ownership. Finkl’s Swiss parent company, Schmolz + Bickenbach, has links to Russian billionaire and aluminum magnate Viktor Vekselberg, according to company records. While not mentioning Vekselberg, the Air Force Continue reading

NASA uses shape memory nickel-titanium-hafnium alloy to fold F-18 wing (US)

The 300-pound wing section was removed from an F/A-18 at NASA Armstrong in Edwards, California, enabling the team to prove a full wing section could be folded using a newly developed nickel-titanium-hafnium high temperature SMA torque-tube actuator, capable of applying 5,000-inch-pounds of torque.

Beginning at the horizontal position, the SMA mechanism was electrically heated and cooled on command to allow the wing to move 90 degrees up and down. More importantly, researchers were able to move the wing section to any selected position within that sweep with Continue reading

Metals fire, moisture create explosion, ATI Millersburg brush fire (US)

A smoldering metals fire apparently mixed with moisture from a summer rain caused an explosion that led to a brush fire at the ATI Specialty Alloys and Components (Wah Chang) complex in Millersburg on Aug. 28, according to a preliminary report by the Albany Fire Department. The explosion was heard inside the plant and nearby residences in Albany, the report states. “It released a large amount of hot embers that were blown/spread by the explosive reaction. Hot metals/materials from the reaction landed approximately 250 feet away from the storage area igniting readily and available fuels,” wrote AFD Division Chief Scott Cowan, in the report. “This violent Continue reading

Heat recovery in steel plants to boost competitiveness (US)

Kristijan Plesnik, energy manager at the steel production SIJ Metal Ravne in Slovenia, talks to ESCI about economic threats to steel production and how these may affect EU climate targets. Kristijan is also involved in the EU-funded ETEKINA project, which looks at new innovative ways to recover waste heat in energy-intensive industries using heat pipes. During the project, SIJ Metal Ravne will adapt a new heat pipe heat exchanger (HPHE) in one of their plants in order to verify and demonstrate its impact in reducing the plant’s overall energy consumption.

ESCI: Are you already reusing waste energy within your plant?

Kristijan Plesnik: Indeed, we are already using some of the waste energy from our electric arc furnaces, so called UHPs, Ultra High Power furnaces. We have had very good experiences with that. ETEKINA draws on this but takes it further. The project has a new approach, as it Continue reading

Tata Steel unveils sustainable steel production technology in Europe (US)

The company has been carrying out long-term testing of its HIsarna plant at the Tata Steel site in IJmuiden, the Netherlands. HIsarna is a completely new technology for producing iron which consists of a reactor in which iron ore is injected at the top. The ore is liquefied in a high-temperature cyclone and drips to the bottom of the reactor where powder coal is injected. This significantly reduces the number of energy-intensive steps required for the traditional steelmaking process. Testing has already shown this technology can lead to a significantContinue reading

India Awaits Advanced Materials for Its Space Program (US)

Over the years, ISRO has localised maraging steel, many aluminium alloys, composites, chemicals, coatings and high temperature items. A hafnium-neobium has been produced to create a superalloy of columbium for advanced missions and needs to be produced on a large scale. ISRO is now looking for aluminium and beryllium alloys to make smaller structures; and carbon-carbon composites for the nose cone of the RLV; and carbon nanotubes for fuel tank systems and silica alternatives for thermal tiles. Next-generation semicryogenic launchers and electric propulsion systems of smaller future satellites need them

A national effort is needed to develop and produce advanced materials to drive the future space programme, Indian Space Research Organisation (ISRO) chairman K. Sivan has said. Along with high propulsion systems for its launch vehicles, the ISRO is pursuing materials that have extraordinary properties, such as aluminium and beryllium alloys and carbon nanotubes. These are needed for the upcoming high-profile national missions such as the Human Space Programme (HSP), the Reusable Launch Vehicle (RLV), re-entering crew capsules, fuel-saving scramjet missions and the distant single-stage launchers. Locally made materials will also help to cut importsContinue reading

Ellwood Group affected by Section 232 steel tariffs (US)

One example Barensfield cited was Ellwood Group Inc. selling stell ingot to a customer in Houston, Texas for extrusion pipe that is exported for use in power plants in China. “Becuase of the new Chinese retaliatory tariffs on imported steel pipe, our Houston customer will likely lose that Chinese business to European pipe competitors,” Barensfeld said. The New Castle facility has one area of its operations that is being directly affected by the steel tariffs, Barensfeld said. Barensfeld said the New Castle facility supplies a Canadian subsidiary with forged steel blocks that are used for molds to make plastic auto parts.

The trade war tariff has invaded New Castle.

Earlier this year, President Donald Trump enacted tariffs on goods from China, Canada, Mexico and the European Union, bringing back an almost forgotten aspect of foreign trade that had been waning in recent decades. However, President Trump and his America First Continue reading
