STEEL PRICES RISE IN EMERGING MARKETS DESPITE SUBDUED BUYING ACTIVITY

According to MEPS, Brazilian service centres are concerned that the latest domestic price levels are not supported by market and economic fundamentals. Presently, most firms are purchasing material only on a requirement basis.

Challenging business conditions persist in the Russian Federation. Trading houses expressed bearish views over the growth prospects for domestic steel consumption in the February-April period.

The outlook for the Indian steel market is unchanged. Distributors remain divided about the government’s decision to extend the minimum import price (MIP), which elapses on February 4. Currently, nineteen products are covered by the framework.

Ukrainian steelmakers are divided over the growth prospects for the long products segments in 2017. In the past twelve months, underlying demand for finished steel products has consistently fallen short of industry projections – particularly, from construction firms and pipe fabricators.

Business confidence deteriorated in Turkey, this month. Local stockists contend that the re-emergence of price volatility in domestic quotations has made it a high risk to complete deals at this stage. The situation has been exacerbated by the strength of the US dollar against the Turkish lira and weak economic fundamentals.

The trading environment is unchanged in the United Arab Emirates. Local service centres are extremely reluctant to purchase material in what they deem as precarious business conditions.

South African distributors plan to persevere with conservative procurement strategies, next month. Shipments to the construction and infrastructure projects remain scarce. End-users intend to steer clear of substantial flat product purchases in the interim.

The outlook for the Mexican steel market is unchanged. Flat product spot market sales decreased. Bearish buyers are reluctant to purchase at current transaction values. The strong US dollar against the Mexican peso is also having a negative effect on sales.

Saarstahl issues final acceptance to SMS group for upgraded high-capacity wire rod mill in Burbach

Saarstahl AG has granted acceptance to SMS group for the expansion of the high-capacity wire rod mill at the Burbach location.To employ larger initial pass sections (180 x 180 millimeters), im­prove the rolling conditions and secure competitiveness in the long term, Saarstahl commissioned SMS group to expand the single-strand roughing mill of its four-strand wire rod mill at the Burbach plant. Besides the expansion of the four-stand roughing mill by two additional stands, this modernization measure included a shear, a four-strand switch and a four-strand pinch roll unit. After the expand­ed wire rod mill was handed over to the customer on time and ready for production the production tests took place. Hence, the moderniza­tion project could be successfully completed about two months before the deadline.

With the expansion of the single-strand roughing mill initial pass sections can now be employed without any reconstruction measures. The final cross section of the roughing train is equal for all initial pass sections and will now be distributed onto the four strands of the wire rod mill by means of the new switch.

Saarstahl AG is one of the world’s leading producers of quality steel for rolled and forged finished products with German locations in Völklingen, Burbach and Neunkirchen. One of the most important production facilities is the four-strand high-performance wire rod mill in Burbach which had been taken into operation by SMS group in 1973 for the first time and now has repeatedly been expanded by SMS group.

The SMS group is a group of companies internationally active in plant construction and mechanical engineering for the steel and nonferrous metals industry. Its 14,000 employees generate sales of over EUR 3.3 bn.

CHINESE CAPACITY CUTS YET TO AFFECT STEEL OUTPUT – MEPS

China is responsible for almost half of global crude steel production. Consequently, actions taken by the country’s steelmakers strongly influence the steel market, worldwide.

In recent times, Chinese suppliers were accused of setting their exports at remarkably low prices. Global steelmakers were often forced to offer their output at low margins or, on occasion, below cost. As a consequence, North American and European steelmakers lodged a number of trade petitions, last year, to limit the direct impact of Chinese imports. However, this month, several US and European service centres bemoaned the shortage of Chinese cold rolled and hot dipped galvanised coil. With very few third country suppliers willing to fill the void, left by China, regional producers have raised transaction prices for these two products.

The Chinese steel sector has stated its intent to reduce excess manufacturing output to address the issue of global overcapacity. The government pledged to remove between 100 and 150 million tonnes of steel capacity in the five-year period up to 2020.

Recent government estimates indicated that as much as 80 million tonnes was eliminated in 2016, against a declared target of 45 million. However, it is unclear how this was achieved. The China Iron and Steel Association previously remarked that last year’s figure included the closure of idled operations.

In fact, China’s National Bureau of Statistics reported that domestic crude steel output, in 2016, increased by 0.6 percent, year-on-year. In the absence of significant production cuts, MEPS believes that vast quantities of Chinese material will continue to enter world markets. This is likely to maintain a degree of negative pressure on global transaction values, in the medium to long term, as oversupply continues.

Xingcheng Special Steel has placed an order with SMS group for the modernization of bar mill No. 1

The Chinese company Jiangyin Xingcheng Special Steel Works Co., Ltd. from Jiangyin, Jiangsu Province, China, has placed an order with the SMS group for the modernization of its SBQ mill “Bar Mill No. 1”. The bar mill that has an annual capacity of 1,000,000 tons will thereby be expanded to include a 3-roll precision sizing mill (PSM®) of type 450/4.The high-performance bar mill with its capacity of more than 330 tons per hour will then be able to achieve closer rolling tolerances than is the case today. Thanks to the possibility of free-size rolling, all diameters in the range from 40 to 130 millimeters can be very flexibly rolled from a small number of feed cross-sections. The hydraulic adjustment of the rolls that permits roll gap control under load allows dimensional deviations due to temperature or material behavior to be equalized. A complete workshop for roll changing and adjustment in the cassettes, including an optical setting gage, also forms part of the SMS group scope of supply.

Xingcheng Special Steel is considered one of the largest roller bearing steel producers in the world, but also produces a wide range of other quality steels.  Around 6.9 million tons of steel are produced per year at the sites in Jiangyin and Wuxi.

The SMS group is a group of companies internationally active in plant construction and mechanical engineering for the steel and nonferrous metals industry. Its 14,000 employees generate sales of over EUR 3.3 bn.

Zekelman Industries places orders with SMS group for modernization of ERW tube lines

Atlas Tube, a company of Zekelman Industries, reiterates its trust in tube welding technology from SMS group. Over the past two years, the company has placed several orders with SMS group aimed at expanding and enhancing the product spectrum of the 8 5/8-inch and 16-inch lines installed in Harrow, Canada, and the 16-inch line installed in Blytheville, U.S.A.SMS group has now received several follow-up orders for the 16-inch tube welding line which was moved to Blytheville, Arkansas, in 2006 and which SMS had already extensively modernized and extended as part of that relocation.

The line is now going to be equipped with a completely new sizing section to expand the product spectrum and improve productivity. The use of URD® (Uniform Rigidity Design) stands in the sizing section will significantly shorten the size changing times in future.

Once the upgrading measures have been completed, the line will be able to roll structurals (round tubes with outside diameters up to 18 inches) as well as square and rectangular hollow sections. Hollow section sizes will range from 14 inches x 14 inches square to up to 18 inches x 10 inches rectangular. The maximum wall thickness will be 17.3 millimeters.

In order to optimize the cross-welding process, the welding equip­ment on the cross-welder will be replaced with the PERFECT arc® system developed and patented by SMS group. No transformers will be required here, the systems will be operated using IGBT (Insulated-Gate Bipolar Transistor) power electronics, with the welding current completely digitally controlled. As a result, the welding machines can attain an efficiency rate of over 90 percent. Compared to older welding techniques, energy savings are up to 30 percent, depending on the operating point. This will further improve process stability, particularly with heavy walls, and contribute to the increase in productivity.

The installation of an additional pinch roll/breakdown stand in the 8 5/8-inch ERW line in Harrow, Canada, will allow higher grades and greater wall thicknesses to be produced in the future. Furthermore, the additional stand will enable the existing product portfolio to be expanded.

Two newly developed inside scarfers have been supplied for the 16-inch line installed by SMS group in Harrow in 2000. These scarfers are a further optimization based on Zekelman Industries’ and SMS group’s experience of the original scarfers of proven SMS design. The inside scarfers, which are equipment crucial to the quality of the tubes, are now designed for the extended wall thickness range of up to 17.3 millimeters. The new scarfers are already in operation and have been performing very successfully.

With these modernization measures, Zekelman Industries is strengthening its leading position in the production of structurals in the North American market.
