Description
従って、本発明の目的は、鋼腐食抵抗性の最適な組み合わせと最適な溶接性とを有し、そして、自動車シャシ製造用又は屋内電気機器製造用の材料としての使用に特に適当なフラット鋼生成物（Stahlflachprodukt）をつくることであった。 Accordingly, an object of the present invention, and a best combination and optimum weldability of the steel corrosion resistant, and, in particular, suitable flat steel for use as a material for automobile chassis for manufacturing or indoors electrical equipment manufacturing It was to make a product (Stahlflachprodukt).
各側に最大で２５ｇ／ｍ２のコーティング重量を有する先行技術に対して、本発明によるどぶ漬けガルバナイジングされたフラット鋼生成物は、最小限のコーティング重量で優れた腐食抵抗性を有している。低いコーティング重量と、それに関連する各側最大３．５μｍの低いコーティングの厚さと、更に、高い腐食抵抗性とが組み合わされることによって、本発明によるシート又はストリップは、個々のシートエレメントの溶接によって製造される部品の製造用に特に適当である。従って、本発明によるシート又はストリップから形成される個々のシート部品を、高い溶接速度でのレーザービームによって、経済的に、そして、最適な結果を伴って溶接することができるという点で、本発明によって製造される鋼板を用いて自動車シャシ又は屋内電気機器技術用のエレメントを製造することができる。 In contrast to the prior art with a coating weight of up to 25 g / m 2 on each side, the soaked galvanized flat steel product according to the invention has excellent corrosion resistance with a minimum coating weight ing. By combining the low coating weight, the associated low coating thickness of up to 3.5 μm on each side, and the high corrosion resistance, sheets or strips according to the invention can be produced by welding individual sheet elements. It is particularly suitable for the production of parts to be produced. Thus, the invention provides that individual sheet parts formed from sheets or strips according to the invention can be welded economically and with optimum results by means of laser beams at high welding speeds. it is possible to manufacture an element for a motor vehicle chassis or indoors electrical device techniques using steel sheet produced by.
溶融浴上でのスラグの偏り及び金属間相（intermetallische Phasen）の形成を防止するために、前記浴の表面上へ、不活性気体流を導くことが好ましい。前記不活性気体流は、コーティングの厚さを調節するために使用されるストリッパーノズルから導かれるか、又は、霧状に不活性気体を浴表面へ分散させるセパレートノズルから供給されることができる。あるいは、不活性雰囲気を保持している囲いによって、溶融浴全体を取り囲むこともできる。前記目的用に特に適当な不活性気体としては、窒素を挙げることができる。 To prevent the formation of bias and intermetallic phases of slag on the molten bath (intermetallisch e Phasen), onto the surface of the bath, it is preferable to direct the inert gas flow. The inert gas stream may be derived from a stripper nozzle used to adjust the thickness of the coating or may be supplied from a separate nozzle that disperses the inert gas to the bath surface in the form of a mist. Alternatively, the entire molten bath can be surrounded by an enclosure that maintains an inert atmosphere. Nitrogen can be mentioned as an inert gas particularly suitable for the purpose.
