Bainitic Tech Invented


China established its first bainite steel company yesterday in Beijing, a move hailed by economists as set to improve the country's ability to manufacture top quality steel and steel products.


Beijing Bainite Steel Company (BBSC) is backed by China National Metals and Minerals Import and Export Corp (Minmetals), one of the country’s first 55 trade conglomerates,and the prestigious Qinghua University.


BBSC has state-of-the-art Mn-B air cooling bainitic steel technology which is unique to China and patented throughout the world.


The technology, invented by Fang Hongsheng professor of Qinghua University, has been regarded by the US Steel Company as the best type of bainitic steel in the world for its low cost and high quality.


Bainitic steel was discovered in the 1930s and is deemed superior to other kinds of steel in making grinding balls and cast steel used mainly in mines and the electric industry. It is energy- saving and causes little chemical pollution.


So far, there are three other major types of bainitic steel in the world, namely, Mo-B series, Moderate series and Non-Moderate series. They all consume too many precious elements such as molybdenum (Mo),tungsten (W) , nickel (Ni) and chromium.


But the Mn-B type of bainitic steel does not contain Mo, W or Ni. It mainly uses man?ganese which is not a rare element.


With the technology, China has got the upper hand over other major producers like the United States which can only make low-carbon bainitic steel used for warships and cars. Now China is also able to produce medium and high-carbon bainitic steel which is used to manufacture the much-sought-after wear-resistant tools , such as grinding balls.


While bainitic steel is still rare in the world markets because of its high costs, BBSC will enable China to start mass production. The company has established three bainitic steel plants,three grinding ball plants and two bainitic cast steel plants in the country. It also boasts a cluster of factories manufacturing various springs, sophisticated die blocks, auto front axles and other machine components.


Minmetals, which has established 70 wholly-owned and joint ventures in 25 countries and regions, will serve as an effective channel for BBSC's exports.


So far, BBSC has forged links with Australia, New Zealand, Canada, the United States and Southeastern Asian countries to provide them with bainitic grinding balls and wear-resistant cast steel.


The success of the company shows how it is supporting China's effort to improve the quality of its export commodities in 1991 ?1995.

貝氏煉鋼法的發明

中國昨天在北京建立了第一家貝氏鋼鐵公司,此舉被經濟學家們稱贊為認真著手改進生產優質鋼和制造優質鋼產品能力的措施。


北京貝氏鋼鐵公司BBSC得到中國首批55個貿易聯合企業之一——中國國家金屬和礦產品進出口公司(Minmetab)和著名的清華大學的支持。


BBSC具有現代化的含錳貝氏鋼Mn-B空氣冷卻貝氏鋼冶煉技術,這是中國獨有的技術,并在全世界獲得專利。


這項技術是由清華大學方宏生譯音教授發明的;由于成本低質量好,美國鋼鐵公司認為用這項技術煉出的鋼是世界上最好的一種貝氏鋼。


貝氏鋼是30年代發現的,并被認為在制造主要用于礦山和電氣工業的磨球和鑄鋼方面優于其他類型的鋼,它既節約能源,又幾乎沒有化學污染。


迄今,世界上還有另外三種主要的貝氏鋼,即含鉬(貝氏鋼)系列、中常系列和非中常系列。這三種貝氏鋼消耗的像銪(Mo)、鎢(W)、鎳(Ni)和鉻(Cr)之類的貴重元素都太多。


但是,含錳貝氏鋼(Mn-B)不含鉬、鎢或鎳,它只用到非稀有元素錳。


有了這種技術,中國就取得了對其他主要鋼鐵生產國像美國的優勢,美國僅能生產制造軍艦和汽車所需的低碳貝氏鋼。今天,中國還能生產中碳貝氏鋼和髙碳識氏鋼,用來加工制造市場上供不應求的耐磨工具,供磨球。


由于成本高,貝氏鋼在世界市場上還不多見,而BBSC卻使中國能開始批量生產。該公司已在全國建立了三個貝氏鋼鐵廠、三個磨球廠和兩個貝氏鑄鋼廠。它還以擁有一批制造各種彈簧、復雜模板、汽車前輪軸及其他機器零部件的工廠而引以為豪。


Mimnetals巳在25個國家和地區建立了70家獨資和合資企業,它將有效地起到BBSC出口渠道的作用。


到目前為止,BBSC已同澳大利亞、新西蘭、加拿大、美國及東南亞國家建立了聯系,向這些國家供應貝氏鋼磨球和耐磨鑄鋼。


BBSC的成功,表明該公司在支持中國在1991?1995年期間改進出口產品質量上起著多么大的作用。
