Chamber Furnaces with Mobile Floor


Available electric resistance chamber furnaces, with a mobile floor can be used for tempering, normalization, drying, sintering of ceramics, decorative baking of painting on glass and other processes that require heating of the products up to 1260 ° C.


The furnace consists of two parts – a stationary housing and a movable cart (floor). The products that are heat treated shall be placed on the cart when it is removed from the process chamber in an end forward position.
The furnace casing is made of sheet and shaped steel sheets.
The thermal insulation of the working chamber is made of chemically neutral and resistant to various gas environments light-weight refractory bricks, vacuum formed refractory elements, felts, mats and protective coatings.
Thermal insulation of the floor is made of modern fireclay materials in combination with light-weight refractory and fibrous materials, ordered in a particular way and scheme.
The heating elements made of new high quality resistance alloys, are arranged appropriately in the working chamber.
The drive of the moving cart is electromechanical powered by movable cable.
Upon opening the workspace (moving out the cart) is provided blocking for turning off all heating elements.
The working chamber is divided into thermal zones. Each is equipped with an independently operating temperature controlling system consisting of standard thermocouples and microprocessor programmable PID controllers.
Electrical switchboards are designed for power and control of the furnace with operating voltage according to the design and the control of the thermal processes. The electrical switchboards provide appropriate control and protection of the circuits and automation, providing the required security.
The electrical resistance furnaces and respectively the switchboards for powering and management work with three-phase mains voltage (380 V) – to power the load chain and 250 V for control circuits (command and protective circuits related to the safety).
Available furnaces of this type are made in accordance with the technical assignment of the client and in accordance with the requirements of the technology for heat treatment of the products.
