Prefabrication – TERMOMATIK-TOPLOTEHNIKA

PRODUCTION AND DRYOUT
OF PREFORMED SHAPES
MADE OF REFRACTORY CONCRETES AND MASSES

PRODUCTION LINE

In order to produce high-quality special shapes out of refractory concretes and masses, the company TERMOMATIK-TOPLOTEHNIKA has built a production and dryout line, which consists of:

– Production Hall (15,0 x 10,0 m) and covered storage area (5,0 x 8,0 m)
– Two countercurrent mixers for preparation of refractory concrete. The capacities of mixers are 500/250 and 250/130
liters (working space/working capacity)
– Three vibrating tables with a working surface of 1,200 x 1,200 mm, with a variable number of oscillations of a fixed vibrator
– Three concrete vibrators with vibrating shafts Ø30 – Ø60 mm
– Bridge crane with load capacity of 50,0 kN (5.000 kg) and span 8,0 m, for transportation of materials, manufactured shapes and pallets
– Chamber Furnace for dryout of preformed shapes. Two furnace hearths ensure the continuity in the prefabrication process.

DRYOUT CHAMBER FURNACE

– Power source: electricity 380 V
– Furnace Power: 45 kW
– Workspace dimensions (LxWxH): 2,5×1,6×1,5 m (6,0 m3)
– Furnace capacity: up to 5.000 kg of preformed shapes in one dryout cycle
– Temperature range: up to 450°C
– The forced movement of the atmosphere in furnace is provided by two 2,2 kW fans
– Temperature gradient inside the furnace: ±3°C
– Deviation from the set dryout curve: ±3°C
– The furnace is software controlled via PLC
– The dryout progress is monitored in real-time via HERALD IIoT Platform, which provides information on the current situation and allows immediate interventions during the dryout – on site or through the computer or mobile application.
– The dryout procedure is verified by a Protocol which contains
the start and end times, default and actual dryout curve, as well as all other technical and commercial data on the prefabricate
– Maximum capacity of the production line is 1.200 kg/day

MOLDS AND TEMPLATES

For the production of special shapes from refractory masses and concrete, TERMOMATIK-TOPLOTEHNIKA also makes reusable molds/templates (steel, wood panels), in accordance with the drawing of the finished shape, and makes and installs the necessary reinforcement and anchors made of fire-resistant steel, when they are an integral part of the production of the prefabricate.

Dimensional tolerances for preformed shapes are in the area defined for completed refractory products of this type or according to the special customer’s request. Refractory material can be determined by the customer (specific manufacturer and quality) or supplier of the finished product – shape (TERMOMATIK-TOPLOTEHNIKA d.o.o.).

Also, the customers can supply their materials and their formworks/templates.

All production and supply conditions are defined in the Purchase Order or Contract, in accordance with the requests and requirements of the customer.
