Steam SL Curing Chamber– Product Overview
Product Name: Steam Cure SL
The first curing chamber designed for industrial battery plates.
The STEAM CURE SL curing chamber was first designed and implemented during the 1970s, when plates for lead acid batteries were normally cured under jute bags. During the 1980s we developed the CAM curing chamber head: this consists in a system in which steam is used to create the moisture needed for curing, whereas heating is carried out by a blown air gas burner together with a heat exchanger.
This curing chamber has been designed to create the temperature and moisture conditions necessary to transform the free lead content (Pb) on the treated plates into PbO and to dry + and – plates.
The STEAM CURE SL is a self-loaded: It has a loading area where pallets are placed by means of a forklift truck. The movement takes place through a chain transport.
It is an automatic curing chamber with a capacity of 16 standard pallets. The chamber head generates the desired humidity and temperature conditions inside the chamber in a consistent and precise manner for the entire duration of the curing and drying cycle.
The internal walls are all made of Inox AISI 304 stainless steel so that the chamber will preserve the plates from iron oxide contamination.
The air flow inside the chambers is laminar and horizontal. The horizontal air flow will cure both horizontally or vertically arranged plates with the same high-quality results.
Thanks to the use of steam, each pallet in the chamber is homogeneously cured because steam particles have a smaller diameter with respect to atomized water particles. Osmotic water is used in the STEAM CURE SL as an emergency vector: for example, if during the cycle there is a problem with the steam supply in the factory, the cycle can be completed by using osmotic water.
A PLC and a Siemens KTP operator’s panel are used to control and manage the process, guaranteeing a minimum oscillation of the process parameters, thus assuring consistent quality.
The software program has been designed and set for Industrial battery plates. Obviously, the parameters such as temperature, humidity, and duration of the cycles can be programmed on the basis of your production needs. In the case of a series of chambers, the system can be equipped with a SCADA so that it is possible to have intelligent control of the production system, with visualization of the system in real time with historical data of the graphs and alarms.
