More than 30 foreign countries on steel products enterprise survey shows that/ As the final product is greater than the thickness of 2 mm hot-rolled strip steel demand is declining/ in 1995 was 48% in 2005 will drop to 42 percent/ while smaller than the thickness 2mm of hot-rolled strip the increasing demand/ and from the ongoing preparations for the deep processing of cold-rolled unit and the investment can also see this trend/ 2005/ 0/8 mm 1/2mm thick hot-rolled strip will increase the demand for more than one percent/ 1/2 mm 2/0mm thick hot-rolled strip will increase the demand for more than seven percent/ By 2007/ forecasts the world of ultra-thin hot-rolled strip steel market demand will exceed 1/9 107t/ On the domestic market/ in 1998 the total consumption of hot-rolled sheet 2/9 107t/ to fill the strip of wood supply and demand gap/ in 1998 imports of hot-rolled sheet of about 7/8 106t/ when steel imports accounted for 64/1% of the total/ Clearly/ the domestic hot-rolled sheet huge market space/ particularly the ultra-thin 2/0 mm Hot Strip following the strong demand in particular 8/ 1/2/2 market demand for hot rolled narrow strip Domestic and international market demand for hot rolled narrow strip substantially the same/ greater than 25 mm thickness of the basic product saturation/ less than 20 mm in thickness is in short supply tropical/ Although Chinas broadband mill has a certain scale/ but Chinas light industry/ construction industry/ and so requires a large amount of narrow-band thin gauge steel/ mainly used in the production of thin-walled welded steel pipes/ light steel keel/ and so on/ in addition to hot rolled narrow strip to the Cold Narrow strip mill and the strip mill for special purposes/ such as raw materials/ thus Chinas hot rolled narrow strip steel will not be replaced for broadband/ According to statistics/ Chinas gas output of more than 3 106t/ this narrow strip is also a major market/ In recent years the production of hot-rolled narrow strip of almost doubled/ production and construction in the mill reached 100 sets/ after all production capacity is expected to total more than 18 million tons/ 1/3 hot-rolled plate steel in the future development trend 1/3/1 development of hot-rolled steel broadband Broadband hot-rolled steel plate to deep drawing steel/ corrosion-resistant high-strength hot-rolled steel sheet/ forming of high strength and excellent ultra high strength steel/ ultra-wide car steel plate/ hot galvanized plate/ ultra-fine grain high-strength steel plate for the Development Goals/ Since adopts Tau rolling technology CSP Technology control cooling technology rolling Process Hot Thin Strip therefore can good controls of organizations and Hot Strip Performance/ In the cooling technology/ the temperature is forecast model is based on a breakdown of the cooling boxes and slow cooling device/ the development of high-precision cooling system/ the Organization for steel and property control/ From the ultra-thin hot-rolled strip steel market demand and production status can be seen to heat the cold/ the steel market to determine the ultra-thin hot-rolled strip steel production overall trend is in short supply/ but also showed that the ultra-thin hot-rolled strip steel Broadband will become a hot-rolled steel in another direction/ It is expected that the introduction of the first rolling and cold rolling technology will be a thin slab continuous casting and rolling production of thin strip direct the main direction of development/ 1/3/2 hot rolled narrow strip development direction Increasing product quality than the strip/ adjusting product mix/ hot-rolled narrow strip open up new areas of product applications/ Currently narrow-band hot-rolled steel manufacturing plant in improved quality/ lower consumption and lower costs/ expand the varieties under the premise of small home appliances/ hardware/ furniture/ bicycle parts/ and other deep-processing enterprises for multi-level structure of high-quality carbon steel/ high-quality low-alloy steel / High manganese steel/ stainless steel/ and other high-quality steel products/ as the lead/ only to completely change the main supply pipe to the direction of the situation/ the construction of the new narrow-band hot-rolled steel production line/ product specifications by the rolling mill products at the lower end of broadband/ Which can substitute for some cold-rolled products/ Such as the thickness of less than 1/5 mm hot-rolled narrow strip of alternative cold-rolled strip steel/ can reduce cold-Gaya/ significantly lower production costs and improve the mill efficiency/ To the thin/ wide/ thick direction/ Thin strip production specifications to meet the thin-walled pipe plant to become useful rate of increase/ the need to reduce production costs/ production specifications wide strip/ occupied in the broadband hot-rolled steel (width generally greater than 500 mm of space products/ production specifications thick strip And the development of light steel structure/ Steel structure used to create light industrial factories/ office buildings/ stadiums/ commercial stores/ warehouses/ and the current extensive use of wide 200 mm 350mm/ thick 6 mm 30mm/ long 3 m 12m of the board and board vol/ Hot plate in the narrow strip cheaper than the 600 yuan / t 700yuan/ t/ such as the narrow strip can be used in lieu of boards/ steel structure will enable the entire project cost is a relatively big drop 1/4 hot-rolled strip steel plate significance of the development Strip is a rather special steel products/ the Zhi Gong ratio is very high/ more than 40 percent directly to manufacturers/ sometimes as a strip of cold-formed steel billets/ widely used in the manufacture of metal fittings/ a bike frame/ wheels/ Spring films/ Saw Blade/ and so on/ Through the past five years of statistics/ the consumer can see is a strip of relatively rapid development speed/ Strip production at home and abroad gradually reduce the circumstances/ China/ as a developing country/ to an increasing demand for steel/ although the scale of the automobile industry restrictions/ but hardware products have greater demand at home and abroad/ At the same time
