The Development Process Of Equipment In Hongwang

- Sep 01, 2018 -

                                                                                                                                                ——From Hongwang

When Hongwang was established, there was only one one-meter partial eight-roll mill. This was already a relatively advanced equipment at the time, but it still relied on manual operation. At that time, there were fewer wide-plate mills, and the market demand for quality was relatively low. The products were in short supply.


In order to provide customers products with high quality and competitive price, we use two wider partial eight-high rolling mills. Adopting the advanced control technology of the rolling industry at that time, which greatly improved the stability of the rolling mill, and the precision of the thickness difference and the shape of the plate were precisely controlled. The quality of the products has also been significantly improved at the same time. 

Then we bring in subsequently, continuous annealing and continuous pickling technology, and realize the automatic control of the rewinding and unwinding. The temperature of the annealing furnace was introduced into the PLC closed-loop automatic control technology to ensure the hardness of the strip. The pickling line has also been added to the electrolytic dephosphorization unit to greatly improve the subsequent pickling effect.



After more than a year of hard work, the first domestic stainless steel five-roll rolling and continuous annealing pickling automatic production line was successfully put into operation in Zhaoqing Hongwang, achieving large-scale production and reducing production costs. Some new processes and technologies are being used in this production line, such as steel belt automatic laser welding technology, automatic wearing belt, tail-tail technology, strip steel full-process tracking technology, automatic plate type control technology, etc., the entire line has realized the computer full digital control. 

These new processes and new technologies have effectively guaranteed the quality of the products and achieved high-speed, high-efficiency and stable production. Only by keeping up with the pace of the times can we create more value for our customers and go further.
