Schaaf – The Specialists for Hydraulic High-Pressure Tools

Superior and Flexible

For about 30 years Schaaf GmbH & Co. KG is involved in the development and manufacturing of hydraulic high-pressure tools. The worldwide active company lives of its innovative solutions and convinces with excellent quality. Schaaf employed about 70 employees at its headquarters in Erkelenz in mid 2006.

Since the company was founded in 1977, everything at Schaaf is about hydraulic highpressure tools. First it was just about screw tensioning devises, hydraulic nuts and its accessories. Today a variety of high-pressure tools are part of the product range for the whole industry. The products from Schaaf find applications in all areas of engineering in the steel industry, civil engineering and structural engineering, in the chemical industry, at power plants as well as in the off-shore and on-shore technology.

The advantages of the hydraulic pretension mechanism tools come to use in all field of application. With the screw tensioning devises and hydraulic nuts, connections can be tightened with the highest degree of accuracy. During pure axial pretension force creation no torsion force occurs, the screws are not subjected to force and twisting does not occur. The list of further points, which speaks for an axial screw pretension, is very long. It contains a significant plus for safety and an ease to work with hydraulic systems.

Development Course

The development of the company went extremely fast in the past 10 years. Schaaf expanded the facilities of the production plant in this time frame by a factor of 20, the construction was increased by a factor of 3 and the amount of employees went from 6 to 70 from 1990 to mid 2006, which means it increased ten folded. The production runs 3 shifts on six days per week. The company has a vertical range of manufacture that almost reaches 100 % of the mark.

An important cornerstone of the company philosophy is the principle idea that a stable company politic produces trust. Management counts on the managing director Ralf Köllges, MBA to achieve consistent quality and a continuous improvement process.

Composite Rolls for Bar and Rod Mills:

EcoRolls increase your production and lower costs

Example based on a German wire producer: On stand 10, when 5.5 mm wire is produced, the costsamount to 0.37 € per tonne when cast-iron rolls are used. Using SCHAAF EcoRolls, the costs have beenreduced to 0.06 € per tonne. SCHAAF rolling capacity: 594,000 tonnes Standard rolling capacity: 163,000 tonnes

Versions

The standard version of the SCHAAF EcoRolls consists of the following components:

Body of forged, high-tensile steel; manufactured
with the technically necessary tolerances
Hydraulic Nut with mechanical locknut for highest
axial tensioning forces
Screw-on labyrinth rings
Spacer rings of high-tensile forged steel between
the roll rings

Advantages

SCHAAF EcoRolls offer you many advantages compared to conventional solid rolls or other composite rolls:

Longer rolling times of the mill
More tonnes per pass
Fewer interruptions to rolling schedule
Pass dressing less deep
Shorter dressing time
Reduced roll stock
Improved surface quality of the rolled product
Less scrap
Shortened, reusable labyrinth rings
Continuously reusable roll body
Hydraulic Nut with high axial clamping force
No keyways, no cracks in the roll rings
No slippage of roll rings
Safe mounting and demounting of the SCHAAF Hydraulic Nut when changing the roll rings at the mill or, if requested, at Schaaf GmbH premises.

A-LOC
Axial LOCking – Less wear thanks to a highly efficient
method of mounting roll rings free of any tensile stress

A-LOC Axial Roll Ring Locking System

The new A-LOC removable axial roll ring locking system is an optimum, highly efficient method of mounting roll rings free of any tensile stress. An important feature of the new A-LOC locking system is that it is possible to centre the roll ring and exert a high axial tension force using a single tool. This optimize the roll torque transfer and produces the required rotational accuracy. The removable A-LOC locking system provides huge cost savings in comparison with other conventional systems.

Main Features:
Mounting roll rings free of any tensile stress through optimized roll torque transfer
Roll rings have a longer tool life and roll modules have a longer service life
Cost intensive existing parts such as a roll rings, roller shafts, sliding rings, bearings can be used without changing.
Advantages:
Reduced rolling mill downtime
Less rejected rolling stock
Huge cost savings in comparison with other conventional systems
No need to carry large stocks of cost-intensive parts
Improved working conditions and reduced risk of accidents

Examples of applications:
in rolling mills
in wire drawing processes
anywhere where radial tension sensitive parts need to be mounted
