1、Inheriting the spirit of “add glory” to achieve further successes
In the 1950s, Shougang Gitane predecessor of the Beijing Steel Wire Factory, Tsinghua University and Beijing Steel Institute (now the University of Science and Technology, Beijing) around the localization of electric wire to open the road of research and development and production. With the enterprise research and development and manufacture of the first domestic iron chromium aluminum electric wire products, breaking the product dependence on imported products, the state praised the enterprise for the country's achievements, the enterprise's original site in front of the road named “Add Glory Road”.
As a professional enterprise producing electric heating materials for many years, Shougang Gitane has not stopped the development and optimization of products in this field. Enterprises and a number of institutions of higher learning and scientific research institutes continue to carry out joint scientific and technological research, to achieve a number of products of the domestic leading, was awarded the national speciality and speciality of new “small giants” title. Among them, the 0.01mm product is another sound research result in this field.
The “silk steel” is mainly used in the gas boiler industry, i.e., the spherical head used to improve the combustion efficiency on the fully premixed burners of natural gas-fired industrial kilns. In addition, it is also “into” the field of environmental protection automobile exhaust gas purification, used in diesel vehicles carbon particulate trap filter. “silk steel” not only to ensure uniform temperature distribution under combustion conditions, but also to inhibit nitrogen oxides and carbon monoxide emissions, to promote full combustion has a good effect, high-performance iron-chromium-aluminum fiber wire to obtain the Ministry of Science and Technology, ‘national key new product’ certificate, technical The performance indexes have reached the international leading level.
The first-class product serves high-end and has rich and diversified application scenarios. Due to its light and soft characteristics, the product can also be combined with other materials to become anti-radiation clothing, providing more special people with work and life protection.
Shougang Gitane Company adheres to the road of specialization, specialization and new development, continuously expanding the market of industry “leading” enterprises and famous brand enterprises, aiming at the national “double carbon” goal, actively research and development of energy-saving and environmentally friendly, carbon-reducing and emission reduction of high-end new materials urgently needed for clean energy, forming a benign development situation with the synergistic linkage with the upstream and downstream of the industrial chain and the innovation of business model. It has formed a benign development situation of synergistic linkage with the upstream and downstream of the industrial chain and mutual promotion of business model innovation.

2、Open up the “blue ocean” market, it's the right thing to do
Opportunity is always given to those who are prepared. In a home appliance exhibition, Shougang Gitane marketing department salesman Feng Jinyong in talking to the salesman learned that they promote high-end gas water heaters on the flame carrier is an imported material, combustion is good, long life, low emissions.
Out of strong professional sensitivity, back to the company after Feng Jin Yong told this information to the then Minister of Technology Development Yang Qingsong. Looking for new product development direction of Yang Qingsong and technical staff access to a large number of professional information, after a detailed analysis and argumentation, keenly aware that this is a very promising piece of “blue ocean market”. This is a short board of China's gas water heaters, but there is no reference to the relevant data, indicators, research and development from where to start? Can only feel the stones to cross the river.
Since there is no “boat” to “cross the river”, we should first feel the position of the “stone”. “Not only traveling, but also business trips. Yang Qingsong in Hunan customers stayed for a week, a detailed understanding of customer needs, firm determination to develop high-performance ferrochromium aluminum fiber wire. The company's leadership team also gave advice after the study, “We have drafted the motor vehicle purification filters with iron-chromium-aluminum fiber wire” national standards. Do not go on the basis of the wholesale denial of the existing alloy composition to get another brand, from the uniformity of the alloy and other directions to make more efforts, so as to get twice the result with half the effort.”
The production process of “silk steel” is very complex. Alloy precise design, cleanliness heat treatment process, strict control, drawing optimization and enhancement of each process can not be taken lightly. After repeated discussions among technicians, the trial manufacturing process of the whole process of “silk steel” was finally determined. Length of nearly 2 meters, 15 centimeters in diameter cylindrical ingot and more than ten elements, in the 1600 degrees Celsius high temperature reaction fusion, and then through the Gitane“SPSRK”brand hardcore process of rolling, stretching, in order to produce as “fluffy” as light “Silk steel”. Technicians and production operations staff together to challenge the control limits of Gitane maintained for decades, and constantly innovate the operation method to achieve production and processing success.
“Hard science and technology + high-end manufacturing”releases innovation dividends, greatly enhancing the added value of Gitane alloy materials. Through many rounds of testing, Gitane ferrochrome-aluminum alloy wire materials, the world's largest manufacturer of fibers and their products, Belgium Bekaert company identified as qualified, Gitane successively for the domestic supply of several related high-performance ferrochrome-aluminum fibers downstream manufacturers, a number of batch of products processed by the “silk steel” out of the country.
3、“Steel Embroidery” Cultural and Creative Empowerment Complements Each Other
Twisting, picking, hooking, dialing, alternating, a set of actions in the clouds. In the blink of an eye, a theme for the “smooth sailing” of the “silk steel” winding painting, by the shopkeeper's skillful hands to complete the production. Onlookers gathered in front of the “silk steel - steel embroidery” works in the cultural and creative store of Shougang Park Three Blast Furnace, discussing this unique Shougang, the incredible “steel art”.
“Silk steel” and cultural creation collision, so that Shougang Gitane company and the garden service company Shougang Cultural Creation jointly launched the ‘steel embroidery’ cultural and creative products fire out of a new height. Behind the exquisite cultural and creative products, full of more and more whimsical and technological content. “Steel art” of the exquisite, from the exquisite technology. “Silk steel” diameter of only one-tenth of the thickness of ordinary A4 paper, from a distance of five meters away from the position without the help of bright light almost can not see the appearance of steel wire. It is a collection of light, fine, soft in one, is above 1000 degrees Celsius still has a high resistance to oxidation and toughness of the electric heating alloy fiber materials.
