Frank Stella on the Roof

Shanghai Metal Corporation

“Frank Stella on the Roof” atop the Metropolitan Museum of Art features two large sculptures, a mammoth piece titled “Chinese Pavilion” and two smaller sculptures. After 11 tense days of preparations, the exhibition, which runs through Oct. 28, opened Tuesday in the Iris and B. Gerald Cantor Roof Garden. A section of stainless steel tubing from the sculpture “adjoeman” (2004) is lowered slowly toward the northern end of the roof garden.

[02stella_slide2.jpg]Mr. Stella’s workers, who traveled from his studio in upstate New York, to assemble the artworks, worked on welding and bolting the looping pieces of “adjoeman,” fashioned from 3,100 pounds of stainless steel and carbon. Given that they helped the artist create it and had recently dismantled it for transport, they were familiar with every nook and cranny. The work’s title is translated as “showing off” or “decorative” in Balinese, the museum.

铁矿石简介-较于碳钢

Shanghai Metal Corporation

    凡是含有可经济利用的铁元素的矿石叫做铁矿石。铁矿石的种类很多,用于炼铁的主要有磁铁矿(Fe3O4)、赤铁矿(Fe2O3)和菱铁矿(FeCO3)等。铁矿石试样经盐酸溶解后,其中的铁转化为Fe3+。在强酸性条件下,Fe3+可通过SnCl2还原为Fe2+。Sn2+将Fe3+还原完毕后,甲基橙也可被Sn2+还原成氢化甲基橙而褪色,因而甲基橙可指示Fe3+还原终点。

    铁矿石是国际大宗商品,战略物资,属于经济命脉一类的东西。世界铁矿资源集中在澳大利亚、巴西、俄罗斯、乌克兰、哈萨克斯坦、印度、美国、加拿大、南非等国。中国作为世界上最大的铁矿石需求国,自身的铁矿石储量虽然不算少,但品质不幸比较低,从工业经济的角度来讲,倒不如从盛产富铁矿的澳大利亚、巴西等国进口。

    可以直接投入炼钢炉炼钢的铁矿石旧称“平炉富矿”,可以直接用于炼铁的铁矿石旧称“高炉富矿”,都带个“富”字。这些富矿一般是磁铁矿和赤铁矿,它们的含铁量都在70%以上。

    贫矿,或者是有害杂质较多的铁矿,则需要先经过选矿,成本一下子就上去了。铁矿石的分类十分复杂,可以按主要成分、有害杂质、结构形态、脉石种类等许多角度来分,每种角度都能分出许多种,工业上选用哪一种,对应于什么样的工艺流程,有非常多的讲究,是一门很大的学问。

分类

磁铁矿

磁铁矿

    是一种氧化铁的矿石,主要成份为Fe3O4,是Fe2O3和FeO的复合物,呈黑灰色,含Fe72.4%,O27.6%,具有磁性。在选矿时可利用磁选法,处理非常方便;但是由于其结构细密,故被还原性较差。经过长期风化作用后即变成赤铁矿。

赤铁矿

赤铁矿

    也是一种氧化铁的矿石,主要成份为Fe2O3,呈暗红色,比重大约为5.26,含Fe70%,O 30%,是最主要的铁矿石。由其本身结构状况的不同又可分成很多类别,如赤色赤铁矿、镜铁矿、云母铁矿、粘土质赤铁等。

褐铁矿

褐铁矿    这是含有氢氧化铁的矿石。它是针铁矿  HFeO2和鳞铁矿FeO(OH)两种不同结构矿石的统称,呈现土黄或棕色,含有Fe约62%,O 27%,H2O 11%,多半是附存在其它铁矿石之中。

    铁相对于碳钢,含碳量高出很多,但是在很多特性上,例如韧性上碳钢要胜出一筹。在名佳利,我们提供多种多样的碳钢产品,包括基本的钢板,钢管,覆铜钢带,甚至还有锅炉板等产品。我们能满足您的需求,让您充分体会到一站式采购的快感。

U.S. Sets Duties on Korean Steel

Shanghai Metal Corporation

The Obama administration imposed duties on steel pipe from South Korea and eight other nations in a victory for U.S. Steel Corp. (X) and the United Steelworkers union, which said they were hurt by unfair competition from overseas. U.S. Steel rose 3.2 percent in New York trading.

The U.S. Commerce Department set duties from 9.89 percent to 15.75 percent on Korean pipe, which is used in oil drilling, according to a fact sheet released today by the agency. Last year, pipe worth $818 million was exported to the U.S. from South Korea. Duties ranging from 2.05 percent to 118.32 percent also were imposed on pipe from the other nations, which sent $722 million worth of pipe to the U.S. last year.

“We applaud their decision to prevent further gamesmanship of our laws and to secure our nation’s economy,” U.S. Steel Chief Executive Officer Mario Longhi said today in a statement.

Carbon fiber wheels propel Tour de France winner

Shanghai Metal Corporation

Hexcel Composites had a helping hand in the efforts of Vincenzo Nibali during his winning ride in the 2014 Tour de France. The rider’s bike wheels were manufactured using Hexcel’s carbon fiber composites. 

wheels
Lightweight carbon fiber bicycle wheels made light work of the Tour de France.

The high performance wheel weighs only 1,000 grams per pair thanks to the low density of carbon fiber in the prepreg that assures a very accurate weight distribution and provides a very light rim with good rotation inertia. Very high levels of stiffness are achieved, enhancing performance and the mechanical properties of the UD carbon prepreg make it possible to use only 12 spokes for both the front and rear wheels, for a unique aerodynamic design.

Social Media Era


In the era of social media and interconnectivity of people through smartphones, it is easy to think you are always connected or can easily reach others through the internet. However, a website address or a person’s LinkedIn account is easily lost in translation if a person does not have something tangible to remind them to reconnect after the meeting. Regardless of the all technology in everyday life, there is still a need for adding a personal touch, such as a business card, to your networking strategy.

When meeting in person, networking with business cards is an affordable approach to reconnecting in the future…

China Coal Prices

Chinese coal prices are now close to their bottom after a long decline brought about by slowing demand and excess supply, an executive with a leading Chinese coal firm said.”I think prices are bottoming out and are unlikely to fall a lot more given the sector-wide losses and rising costs,” said Gong Qingchao, head of sales and executive director with the China Coal Group, China’s second-biggest state coal producer.Speaking at an industry conference, Gong said about a third of China’s coal miners were making losses in 2013, and a further fall in prices this year has meant that an estimated 80 percent of the total are in the red.Tumbling prices, caused by weaker demand due to slowing growth in China and a flood of cheaper imports, have forced many smaller miners out of business, while a slew of majors, including Shenhua Energy and Yanzhou Coal , reported losses for their 2013 results.This week, the benchmark Bohai Bay Steam Coal Index price rose 1 yuan to 531 per tonne after falling for 11 consecutive weeks.
