Furnaces & heat treatment

Preheater system that fits your needs Thanks to its expert know-how and flexible research, SIF MDC has launched an innovative preheater system into the market that was produced to order for the company Rosendahl. The machine was produced with the aim of solving the heating problem of a rigid copper conductor with Ø 6.7mm, 120°C, 200m/min. The system has been designed to solve specific client requirements, with the purpose of improving production per- formance and product quality. This is a preheater system and not just a simple preheater as the company’s systematic approach has helped them design a product where all the com- ponents combine together to create a high performance piece of equipment. Some examples of SIF’s implemented solutions are: Use of the colour RAL9006 to allow the • application of the Kaizenmethod, now adopted as a strategy of continuous incremental improvements by the most up-to-date companies.

Through a remote control, the tem- perature meter can be put in contact with the conductor, obtaining a reliable measure from the interface to check that the set temperature is correct. In case of any difference, due for example to a lower or higher initial temperature of the conductor, it is possible to adjust the temperature modifying the pre- heater system control offset according to the corresponding variations. At this point it is possible to deactivate the temperature measurement system. This is a very functional and reliable choice also because the adjustment and control system of the preheating current, which allows attainment of the desired temperature, is very stable and can reach excellent repeated and reliable performances thanks to this improvement. Since the recent wire 2008 exhibtion in Düsseldorf, the new range of preheaters has been presented with the new system of smart control. This new system allows the client an easy set up of the heating curves, offering a great flexibility of use.

Use of an isolated pulley Ø 600mm • made of conductive alloy and other pulleys Ø 600mm made of aluminium with a ceramic cover for two reasons: in order to reduce heat loss and consequently increase the system performance and in order to increase the system lifetime, but mostly to avoid excessive stress on the rigid conductor. The return pulleys can be adjusted for an easy alignment to the line inlet and outlet heights. System operation at industrial fre- • quency 50Hz for a good penetration of the heating current into the conductor Particular attention has been paid to safety measures with the introduction of: emergency button with safety module • coordinated with the safety system of the line doors with transparent safety glass • (Visarm) for product inspection safety switches on the doors for • system turn-off in case of opening system protection automatic switch • system remote control through an • analogue/digital interface so that the operator only needs to check on tables and databases already present in the line control, thus minimising intervention and maximising results. The company has also introduced a new motorised temperature measure- ment system with an analogue/digital interface.
