Cold Mill 22
Due to the expansion of the galvanizing capacity in IJmuiden, through the construction of the hot-dipped galvanizing line 3 (DVL 3), the construction of Cold Mill 22 (KW22) is necessary. Moreover, this new mill can lend new features to the material from the Direct Sheet Plant, in the area of roughness, shape and material characteristics, which better meet customer wishes.
With the extra cold mill capacity of KW22 it is possible to clear the production of the existing Cold Mill 21 for the hot-dipped galvanizing line for the automobile industry. The capacity of KW22 will mostly be used for the remaining galvanizing capacity (for construction) and the paint section.
Cold Mill 22 will be built at the end of Beitsbaan 22 in a new hall. The partition will remain in place and will be fitted with a type of ‘letter box’ through which the belt will run. This means the cold rolling will be a continuous process. This is new in IJmuiden. It has its advantages for capacity, but, more importantly, also for the quality of the material. That is to say, there is less chance of damage to the beginning and end of the material.
The new cold mill will have a few marked features. The installation will be fitted with three milling installations of six (in stead of four) mills on top of each other. This means that the two work mills (that are in contact with the material) have a smaller diameter, allowing for the material to be made even thinner. Moreover, another mill is situated between the work mill and the support mill. This generates more possibilities for shape regulation.
A second marked feature of the new cold mill is the carrousel-reel. These are two reels on a wheel, allowing you to “fly” change. This saves space in the installation and productiontime.
Third hot-dipped gelvanizing line (DVL3)
The construction of the third hot-dipped galvanizing line is closely connected to the construction of Cold Mill 22. The two projects are more or less parallel and are coordinated by a joint project group. In 2008 both installations will be put into service.
