Tandem Cold Rolling Mill

2025-12-07 00:00:00

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.
Skin Pass Mill

2024-11-12 10:47:34

Skin pass Mill, the one of important facilities in galvanizing line, functions as following:

  1) To create surface roughness of galvanized sheet according to requirement in order to promote the quality of sequential color coating process.

  2) To improve the flatness of galvanized sheet.

  3) To improve mechanical properties of galvanized sheet, to decrease or eliminate yield plateau and stretcher strains.

Beijing YWLX Science & Tech. Co. Ltd, summarizing and absorbing the latest domestic abroad technologies and combining Chinese marketing requirements, has developed medium top quality skin-pass mill of width in 1800mm, 1680mm,1550mm, 1450mm and 1150mm etc..

And the rolling force can be up to 4000KN, 5000KN，6000KN, 8000KN, 10000KN, 12000KN etc., which have been widely used in all kinds of production lines of zinc galvanized, aluminum-zinc galvanized and lithium-magnesium-zinc galvanized and continuous pickling-temper lines etc., with winning the customer praise.

We are the leading manufacturer of Skin Pass Mill in China.
Temper Mill

Main functions

1) Eliminating yield terrace, entirely improving strip’s mechanical property and deep draw ability.

2) Promoting the cleanliness of strip’s surface or obtain a certain roughness of strip’s surface; improving its process ability.

3) Improving flatness and straightness.

4) With the function of soft reduction to change the thickness and mechanical property of steel strip.
Four/Six-Hi Reversing Cold Rolling Mill

2024-11-12 10:47:34

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.
Cladding Rolling Mill

2024-11-12 10:47:34

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.
Agc System For Hot/Cold Strip Rolling Mill

2024-11-12 10:47:34

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.
