YWLX, combining global latest technology of five stands tandem cold mill, has developed a new five stand tandem cold mill equipped with double tension reels, flying shear and Magnetic conveyor belt, which to be of big reduction rate, full continuity, high yield with less invest and low cost. The mill will use new rolling process to produce cold rolling steel strips, especially for wide steel strip and zinc galvanizing basic plate.

If you're looking for high-quality cold rolling mills, you've come to the right place!

Iron and steel industry is the foundation of modern industry, and rolling technology is an important link to transform steel from raw materials into various steel products.

 In 2015, YWLX had successfully developed first production line of special Z-type steel for ZSB ocean petroleum casing pipe. The production line of special Z-type steel has partly solved import substitution.  The special Z-type steel for ocean petroleum casing pipe had before been monopolized by some firms of Japan and Germany. Due to its technical threshold is very high, its importing price is also very expensive. In order to break up their monopoly and achieve the home-made of special Z-type steel, YWLX energized and mobilized its best talented personnel in metallurgical and rolling field successfully to develop first production line of special Z-type steel.  The production line’s success, based on YWLX’s research and development achievements and engineering experiences for many years in metallurgical and rolling field, had broken up technical barriers and tackled many technical difficult problems and developed unique rolling pass for Z-type steel. The production line has been stably and reliably and producing. 

Four/Six Hi finishing reversing cold rolling mills, as YWLX’s matured products, have been used in many Chinese steel firms. Especially, the Six Hi reversing precise cold rolling mill, supplied by YWLX, can roll not only carbon strip steel but also oriented/non-oriented silicon strip steel and stainless strip steel.    YWLX has developed the series of 900mm, 1150mm and 1380mm width of Six Hi reversing cold rolling mill, which produce not only the carbon steel strip, but also silicon steel strip and stainless steel strip. When rolling carbon steel strip(SPHC), the thickness can be reduced from 3.0mm to 0.2mm by six rolling passes without any annealing in process. When rolling oriented/non-oriented silicon strip steel, Its thickness can be reduced from 0.63mm to 0.26mm by 2~3 rolling passes. The thickness tolerance and flatness has satisfied the technical requirements. 

AGC( Automatic Gauge Control) has been an essential device to be used in strip rolling process to promote rolling precision.  YWLX has been pursuing to develop and research completed equipment of AGC since it was founded in 2003.   As the one of YWLX's core technology, YWLX’s AGC had as far as been used on hundreds of cold/hot rolling mills, temper mills and skin pass mills in domestic and oversea. YWLX’s AGC can completely carry out precise control of strip gauge.

Recently, the application of cladding plate and strip is gradually rising, which is replacing with nonferrous materials and stainless steel mainly used in electronic industry, decorative material, chemical industry and automobile etc. In past, exploding cladding and hot rolling cladding technologies had been predominated in the production of cladding plate and strip. The products made by above related process, has been puzzled by low surface quality, Low yield, high energy consumption and higher investment in environmental protection.  The cladding rolling business department of YWLX, combining the latest global technology and process in cold rolling cladding strip, has independently developed cold rolling cladding technology, process and complete equipment, including cladding technology of copper strip and steel strip, cladding technology of aluminum strip and steel strip, cladding technology of copper strip and aluminum strip, cladding technology of aluminum strip and stainless steel strip and cladding stainless steel strip and steel strip. Which can be bonded bimetal or triple metals in one prouction line. The cladding technology of copper and steel and cladding technology of aluminum strip and steel strip have been used in actual production that can produce the cladding coil strip with width in 1000mm and minimum thickness up to 0.2mm. 

YWLX has also developed and manufactured sorts of special experimental Hot/Cold rolling mills for Chinese universities and famous research institutes.  For example: YWLX had developed and manufactured the Hot/Cold rolling mill of Al-Mg alloy strip and Hot Leveller of Al-Mg alloy bar for  Beijing General Research Institute of Nonferrous Metals(GRINM), which played a key role in National key scientific research item and achieved good result. Also, as a professional machinery manufacturer, YWLX has supplied various mechanical/hydraulic/electrical spare parts, such as bearing housings, mill rollers, valve blocks, etc.
