Color-coated roller coater coating process is usually subject to a wet film thickness of coating and curing oven baking solvent load limit, if the product requires a large film thickness, they have repeatedly applied and cured by baking, so the roller coating unit points as a coating a roast, two Tu two bake, bake three-coat three other types to meet different requirements of color-coated coating thickness, and can be more economical and rational use of paint. Among them, two Tu two bake the largest number of units. Roller unit high-speed, high-volume production. Products are widely used in outdoor construction and interior decoration, home appliances, furniture, appliances and so on. 2 curtain flow method initially coated with a roller coating, curtain flow coating machine when using fine coating, liquid coating applied to the strip surface, coated strip without leaving lime color coated roll marks, difficult to control, suitable for the production of high quality color coated appliances. The process is difficult to control, only Nippon Steel Kimitsu plant applications, do not get promoted. 3 powder coating powder coating is a new process is divided into two kinds of powder gun powder cloud technology, a few years ago in Europe and Japan have several sets painted by powder gun technology unit production, its low speed craft, production capacity is small. The recent development of MSC powder cloud technology enables powder coating technology has greatly improved. The process is as follows: pre-treatment powder coating similar to a traditional silver color coated roll coating pretreatment, the outer surface of the pretreated substrate coated with powder binder, by induction heating to 175 ° C, and dried to form 5 ~ 10μm dry film, and then roll through the inner water-cooled substrate cooled to 40 ° C, so a good deal across the board installed in the cabinet in the powder coating Ge, Ge powder coating in a strong electrostatic field next, the rotating brush powder coating powder cloud generated Boxing color coated, to form a powder cloud of the solid paint particles with a high charge, which fly to the high-speed operation of the substrate, to produce sufficient boundary penetration, the powder particles will be uniformly deposited on the strip surface. Powder coated film strip to go through the curing process, through two induction coils mounted transversely curing oven, and a holding furnace treatment, quenching by water cooling, complete segment processes. Powder coating product coating thickness, color, gloss uniformity; scratch resistance, corrosion resistance, chalking good fade resistance; no paint solvent, nor thermosetting adhesive, no explosion and fire hazards; environmental protection safe process. The result is highly dependent on imports of iron ore import prices and domestic steel companies climbed high production costs and other issues. Data show that three quarters of the iron and steel industry profits fell by 84.1%, a decline of 46.8 percentage points from the previous quarter to expand. The way to deal with the industry focused on three areas. First, adjust the structure of iron ore imports to ease the reliance on the traditional three miners. On the other hand, in the steel industry from top to bottom all want to fight for the right to speak of iron ore pricing, launched earlier this year China iron ore spot trading platform for iron ore futures are also in the pipeline. The third point is to increase the proportion of overseas mining rights. According to the target, "Twelve Five" period, to 200 million tons in 2015 to form a new production base overseas. Many large domestic steel enterprises overseas layout has been operating for many years, Baosteel Group, for example, the data show, Baosteel has received 16 million tons of iron ore annually through overseas investment. Sustained overseas distribution to Baosteel has brought tangible benefits, in 2010 iron ore prices, the highest had close to $ 200 / ton, Baosteel profit accounted for a country more than 70 large and medium steel companies profit sum of 26 %.
