DESCRIPTION
This is a directly heated heat-treating furnace that is designed for batch operation and with a vertical, fully gas-tight chamber that is normally sunk below the shop floor level. The furnace door is fitted with a fan for even temperature distribution and a homogenous active gas atmosphere. Nitridation is achieved through the decomposition of the ammonia that is fed into the furnace. To access the furnace chamber, the top cover needs to be removed. The products are mechanically loaded into the furnace and then held by a support frame. The feeding is carried out by an overhead crane.
APPLICATION
Annealing, carburisation, nitridation, nitrocementation, annealing under protective atmosphere and stress-relief of products of different shapes, sizes and weights hung from grates or segments (such as shafts, splined shafts, piston pins, etc.) or of smaller parts in baskets. It is particularly suitable for small and medium-sized plants that heat treat small batches of non-identical parts. The gases that are used include nitrogen, ammonia, carbon dioxide, methanol and distilled water.
BUYING CRITERIA

OUR MAIN ACTIVITIES
Our core business is the manufacture of industrial furnaces and thermal process equipment in accordance with the customer’s process specifications and technical requirements.
We provide troubleshooting, regular or occasional maintenance, as well as the renewal and upgrade of industrial furnaces.
Our company has gained a lot of experience in the construction of steel structures. We ourselves do minor cutting works, while, for doing large-scale ones, we cooperate with highly experienced professional companies.
We undertake the annealing and stress relieving heat treatment of large and heavy workpieces in the furnace.
