ROLLER HEARTHFURNACE FOR COPPER COILS
ARES CRF is suitable for homogenization annealing of copperalloy casting blank strip coils and for recrystallization annealingof intermediate rolled copper alloy strip coils under protectiveatmosphere.The furnace is equipped with a roller bottommaterial transfer mechanism:The heat and cold roller conveyorsallow for a closed-loop circulation of trays in the production area.Meanwhile, loading and unloading coil upenders work inconjunction with loading transfer vehicles, so that copperstrip coils are transferred automatedly in the furnace.
The furnace is heated by gas or electric radiant tubes together withhigh-convection circulating fans, contributing to uniform furnacetemperature and low energy consumption.As the thermal treatmentprocess is protected by nitrogen-based atmosphere, the coil surfaceis bright and oxidation-free after the treatment.After annealing, thecopper coils are cooled rapidly by highly efficient jet cooling devicesstill under protective atmosphere to prevent oxidation after beingdischarged from the furnace.
Compared with the bell furnace,CRF has advantages of small size,large production capacity, low energy consumption, small investment,simple operation, stable and reliable performance, etc., which isespecially suitable for mass production.

BRIGHT HEAT-TREATMENT LINE FOR COPPER STRIP
ARES CSL is suitable for solid solution, recrystallization or stressrelief annealing of copper alloy strips under H2 or N2/H2 protectiveatmosphere, in which copper strips are overhung in the high-temperaturesection and have thus no contact with furnace rollers.Therefore, thesurface of copper strips is bright, oxidation-free and without scratchesafter the heat treatment.
Within the range of 300 °C to l100 °℃, the heat treatment furnace canbe set atany temperature to meet process requirements of alloy copperstrip thicknesses between 0.1 and 1.5mm.
Furnace heating is divided into two sections: The convectionsection and the radiation section.The convection sectionis heated by high-convection circulating fans, throughwhich copperstrips can be quickly heated upto a maximumof 850°C.The radiation section adopts a radiation tubeheating mode, where the furnace temperature is up to1100 °Cmaximum.Thecooling section utilizes high-efficientjet cooling devices to quickly cool copper strips, so thatthe temperature of strips at the outlet is less than 80℃.
CSL occupies a small area and is applicable to a widerange of processes, which can replace flotation furnacesand vertical annealingfurnaces without doubt. Meanwhile,such furnace has characteristics of small investmentsas well as low maintenance costs, conferring greatadvantages to it in the field of copper alloy strips annealing.
