Huixian cold rolling mill information Kindi metallurgy (certified), cold rolling mill information provided by Kindi Metallurgical Equipment Limited. Kindi Metallurgical Equipment Co., Ltd. (www.ye-jin.com) is specialized in the "cold rolling mill, costal cold rolling mill, steel straightening machine, bar straightening and cutting machine, steel cutting machine" of the enterprise, the company of " honesty, hard service "concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Liu. Cold-rolled ribbed steel in prestressed concrete members, is cold drawn carbon steel wire replacement product information Huixian cold rolling mill, in-situ concrete structure, you can substitute Ⅰ grade steel, in order to save steel, is Similar cold working the steel is preferably one. Its performance and application results are as follows: China's national standard "rolled ribbed" GB13788─2000 in LL550 grade mechanical properties are developed with reference to international standards and standard-setting, tensile strength 550N / mm [~ 2], elongation rate according to the German standardization δ [_10] 8% (equivalent to δ [_5] for 12─13%), from the two indicators of cold rolling mill control Fengquan area information, our standard cold-rolled ribbed steel bars no less than international standards low. Metallurgical Equipment Company employees 102 people, more than seven high-tech accounted for 15% of the total production workers, the factory covers an area of ??25,000 square meters, construction area of ??14,500 square meters, the whole plant were set Makino area cold rolling mill production business information, quality testing and other nine departments, three workshops. Gongyi City, Di Metallurgical Equipment Co., Ltd. as a specialized product for cold-rolled ribbed steel equipment manufacturers, I produced the cold rolling equipment, cold-rolled ribbed steel equipment: cold rolling mill, cold-rolled ribbed steel production line, costal cold rolling mill, steel straightening and cutting machine, steel cutting machine, bar straightening machines, hot rolling up machine, cold rolled and twisted, and other equipment. Because cold-rolled ribbed steel surface prescribe or three crescent-shaped ribs, which makes cold-rolled ribbed steel bars and concrete mix consisting of reinforced concrete structure after a rugged, durable, fire performance, and low cost advantages. Cold rolling mill information below, I introduce to you the next cold-rolled ribbed steel is a combination of concrete and how to effectively together: the different nature of the material cold-rolled ribbed steel bars and concrete two can work together effectively, due to concrete After generating the adhesion between the hardened concrete and cold-rolled ribbed steel. It consists of molecular force (adhesive force), friction resistance and mechanical bite force of three parts. Which play a decisive role in the mechanical bite force, accounting for more than half of the total bond strength. To ensure reliable cold-rolled ribbed steel bars and concrete bond between the steel and prevent corrosion is surrounded by a protective layer of reinforced concrete must have 15 to 30 mm thick. If the structure is in aggressive media environment, but also increase the thickness of the protective layer.
