Furnaces with protective atmosphere СНЗ, СШЗ, СГЗ

Furnaces with protective atmosphere СНЗ, СШЗ, СГЗ

Purpose: hermetic design of the furnaces allows working in a non-oxidizing environment, filling the working chamber with protective gases. This furnaces are excellent for hardening, tempering, sintering, normalizing, bright annealing in the environment of Nitrogen, Argon and other inert gases. Electric furnaces are made from the Ukrainian manufacturer Bortek Ltd. for scientific research laboratories and industrial enterprises.


The aim of protective atmosphere: to prevent oxidation, decarburization and other unwanted chemical changes on the surface of the metal.

Explanation of markings:
chamber furnaces with protective atmosphere:   СНЗ – X1.X2.X3 / T   or  СНЗ – X4.X3 / T
pit furnaces with protective atmosphere:            СШЗ – X1.X2.X3 / T  or  СШЗ – X4.X3 / T
bell-type furnaces with protective atmosphere:   СГЗ – X1.X2.X3 / T   or  СГЗ – X4.X3 / T    where is,    
С   – type of heating – the resistance electric furnace;
Н, Ш, Г   – the main constructive sign – chamber, pit, bell-type;
З – atmosphere in the working space – protective atmosphere;
[X1 - width. X2- length. X3 - height] or [X4 - diameter. X3 - height] - the size of the camera in decimeters (1 dm = 100 mm);
T – nominal temperature in hundreds of °C

Control system ______________________________________________________________

         

•  Turning off the power of heaters when you open the door (physical open circuit);
•  Protection against short-circuit and longer overcurrent;
•  Protection from accidental overheating during incorrectly specified temperature;
•  Electric furnace power units are managed by means of contactless semiconductor switches, that includes the maintenance of the power key and ensures quiet operation of the furnace.

Temperature regulator ТРП-08-ТП
(by default) 

Programmer temperature regulator ТРП-09-ТП
(in agreement with the Customer)

Electric furnace operation is controlled by a digital temperature regulator type ТРП-08-ТП (by default), and ТРП-09-ТП.
 
Temperature regulator type ТРП-08-ТП (by default) allows You to set one-step heat treatment program.
 
Programmer temperature regulator type ТРП-09-ТП allows You to organize Input, Working off and Storing 5 independent programs; rise time (lowering) the temperature and time maintaining the temperature at each step (ramp function). Total of 16 steps.
 
All current programs and settings the device is stored in nonvolatile memory. Thermocouple brand ТХА is used as a temperature sensor up to 1100 °С; Thermocouple ТПП - up to 1250°С. When ordering, You can set the temperature controller with programmer (ТРП-09-ТП), which sets the heating program up to 12 temperature regimes, the speed of heating and the holding time of workpiece. The range of automatic temperature control is from 400 °C to 1360 °C.
