Strip mill is a kind of production equipment to roll down steel ingot and billet and make into steel strip, manufactured by the method of rolling to fabricate strip steel, features in high productivity, variety production, strong continuity, take the advantages as easy to realize automation, of wide application, high control precision and complexity, either used for cold rolling workshop, or used for hot rolled strip steel work plant.
Strip mill classification is various, upon the temperature of the rolled steel can be divided into cold-rolled strip mill and hot-rolled strip mill, upon the number of its rollers can be available into four-roller strip mill, six-roller strip mill, and multi-roller mill etc., and upon processing classified into continuous strip mill and reversible strip mill.
The tendency of the strip mill that NHI developed and fabricated is continuous, automated, specialized; and in improving product quality, reducing energy consumption has made great progress, that make the performance to be much improved such as strip cold rolling mill and reversible rolling mill, developed a completion continuous strip cold-rolling mill, hot-rolling mill and a series of advanced equipment. Strip mill AGC hydraulic pressure, profiling control, computer control and testing procedures are becoming more and more perfect, rolling varieties are becoming continuously expanding. Adopting continuous casting, rolling and other new rolling control methods, adapt to new request to improve product quality and to improve the economic benefit of various special structure strip mill. Currently, NHI is capable to design and manufacture a variety of specifications steel rolling production line, also available to customized specifications of larger strip rolling line completed equipment.
