Stainless steel keel product will create a new era of building applications

        As we all know the benefits of high-rise buildings, and stainless steel in construction applications are not uncommon. However, how to expand the scope of application of stainless steel as a building material, especially in the ultra-high-rise buildings, is still a difficult and complex issue. Because it involves not only the scientific theory of knowledge, but also to meet the challenges of the operability and other aspects.
         Experience Day in the global stainless steel leader Outokumpu recently held in Berlin, the construction industry-related person in charge of the reporter interviewed Dr. Outokumpu construction sector Joern Teipel. From the perspective of a physicist and his material experts, with everyone to explore the importance of the stainless steel material for the industry, as well as future trends in this area.
         Joern Teipel said: "I have always been very interested in the construction industry, considered a building fan, history of architecture and its evolution to a strong interest in every new city, I will go to explore and enjoy a wide range of construction. And this is my great pleasure to travel in one. "During the PhD, his research interests are physics, mainly in the non-linear object, relates to an optical detection, optical appearance, optical reflectance surface treatment, and these subjects field of knowledge is important for building. Dr. Joern Teipel said: "The content is not strange for me based on professional education background, I can easily grasp the material in the building to find the perfect combination of a number of choices in this study experience for me. career choice and development have had a significant impact.
         Meanwhile, Dr. Joern Teipel said: "For material suppliers, the most important task is to determine what is really needed is an architect, and we should learn how to meet their needs Outokumpu's stainless steel both beautiful and. lasting properties, it can effectively help architects achieve their vision. Our responsibility is to make the architect's dream become a reality. "
          Development of the construction industry depends on the development of engineering works not only to learn, but also depends on the progress of materials science, mechanical engineering, energy and power engineering, electronics, communications, automation, computer science and other related disciplines. If the architect is a dreamer, so materials science and other engineering scientists is their "Dream man." Dr. Joern Teipel said in an interview, in the construction industry, "the architect of the exterior walls if there is some special design ideas, we can help achieve, will be considered together with all the possible combinations, we have a total of 70 different surface and polished product portfolio, which has a relatively large number of. "
    The future of stainless steel products, especially stainless steel keel into a large number of products will be put into our daily lives and the construction industry, stainless keel products will be favored for the construction industry.

Cold-formed steel roll forming machine processing product defects and causes?

 First, cold-formed steel finished weld cracking or rupture
         Reason: 1, the thickness of the width of the raw material in the production process is unstable. Weld or produce false welding; 2, extrusion welding inadequate, poor weld fusion.

         Second, cold-formed steel products do not meet the criteria bend
         Reason: 1, pipe wall thickness unevenness (uneven thickness or raw material produced by the manufacturer); 2, roll diameter of different pipe deformation leads to uneven bending.

         Third, cold-formed steel product size fluctuations
         Reason: 1, the operation when adjusting the roll improper; 2, solid too fast, leading to size fluctuations.

         Fourth, cold-formed steel products sectional serious glitch, have a "rat tail"
         Reason: 1, cutting blades become blunt, so the gap is too large tends to remain; dull blade, or improper installation also easily lead burrs; 2, pipe welds have squeeze out excess metal. Welding system is not standardized and easier to make the cut when leaving burrs.

         Fifth, cold-formed steel products weld surface is not flat, convex clear
         Reason: 1, convex weld, the weld planing depth darker, resulting in lower flatness. 2, concave weld, the weld planing depth shallower.

         Six, cold-formed steel products square tube or rectangular tube R angle fluctuation
         Cause: Improper production operations

         Seven, then welded tube body phenomenon exists
         Reason: In the production process, the raw material is carried unwinding package rolling, each volume of raw materials without the interface, in order to continuous production, the need to end of the first two volumes of raw materials welded.

         Eight, the port saw irregular, tilted or uneven.
         Cause: shear deformation in shear makes port missing.

Color steel sandwich panel roof design(一）

  

  Sandwich panels used in construction, is a new development of building technology, in which there is not a previous set of load-bearing building board, insulation, waterproofing and renovation in one of the functions. Based on this characteristic, in the application of sandwich panels in buildings, we should give full play to consider these characteristics and avoid the problems posed by these characteristics. Sandwich panels used for large-span industrial buildings and public buildings roof, most of them for the plate, purlin structure, sandwich panels are now produced by Sandwich plate processing equipment.
   Roof sandwich panels do not only have to bear the weight of construction to withstand the load, snow load and negative wind loads, it must be connected to the roof purlins, load transmitted beams, columns by the purlins and the like. Therefore, the connection point to the emergence of several plates and purlins; roofing Apart from sheet metal, there are several sorts of flashing accessories. Pan of water between parts, between the pan of water and the plate, between the board and the board, between the member and the surrounding buildings flashings should be linked, which resulted in a large number of connection points. These connection points above process constitutes a key color steel sandwich panel design.

Roll forming machine 6 Ways to improve stampings life!（二）

2, the correct choice of roll forming machine stamping parts and materials

    Really use roll forming machine work process different materials have different stamping parts strength, toughness and wear resistance. The use of advanced materials under certain conditions can make to improve the durability of the good times. Therefore, in order to improve the durability of stamped parts must choose good material.

    Toolox series of material, is a kind of high toughness, high wear resistance, a pre-stress basically no hard new tool steel. And with a very high purity, very fine grain size, S, P content is very less carbide precipitation less content, and very uniform. Because of the special composition design, Toolox series material has a very excellent surface processing performance, which after Toolox44 nitriding surface hardness can reach HRC65 above, Toolox40 surface hardness can reach HRC62 or more, Toolox33 surface hardness can reach HRC58 or more, the depth of up to 1.8mm.

    Toolox series of material have the above characteristics, the material used in making the Toolox Series Stamping part has a special advantage.

1) thick steel plate (a typical case of punching a thickness of 35mm steel    plate), stainless steel, and nonferrous metal plate stamping mold, typical air conditioning fin die.

2) drawing dies, stainless steel drawing dies.

3) cold extrusion die cold extrusion 304 stainless steel, the thickness of 0.5mm or more, replace the DC53 and other materials, the effect is very good.

4) roll forming machines make use of high dimensional stability requirements of large stamping parts.

Roll forming machine 6 Ways to improve stampings life!（一）

    Roll forming machine stamping process is an essential process equipment, improve product quality, extend product life, improve production efficiency have a decisive role. However, since the stamping parts in the production process often lose their jobs wear size, it makes it difficult to meet production needs. Therefore, improving the durability of stamping dies (life) is critical.
Roll forming machine to improve the durability of the stamping method generally have the following:

1. An improved roll forming machine stamping parts of the design

    Whether to study a press roll forming machine part is designed to improve the durability of the foundation stamping. Therefore, when dealing with product design stamping molding adverse conditions and take effective measures to improve the durability of stampings, such as life design stamping holes often manifested in the red hole punch. For this type of stampings, it should be designed so that small punch to shorten its length to increase the strength, should also adopt the method of strengthening the guide sleeve to protect small punch. In addition, the stamping design, should be fully taken into account in the form of fixation methods and guide in the form of mold, punch, and determining and upper and lower rigid template center of pressure and other factors. Especially for stamping die, the selected clearance value has a great influence on durability. At design time, the gap should be a reasonable choice stampings, the gap value can not be too small, otherwise it will affect the life and durability of stamped parts. Practice has proved that, without affecting the quality of stamping the case, appropriate to enlarge the gap can greatly improve the durability of the stamping dies, sometimes even several times and several times increase.
