  • Specification

JK Vertical tube furnace using SiC rods as heating elements. It is widely used for materials or chemical lab to sinter all types of new materials samples under vacuum or other gases condition. The temperature of EQ-GSL-1500X40 tubing furnace is controlled by high precision SCR (Silicon Controlled Rectifier) digital controller with accuracy±1oC and 51 segments programmable up to 1400C. The tube furnace can be placed into a glove box to process material in various atmospheres
VerticalTube Furnace is with the tube is vertical which is with 6 diameter one end closed alumina tube and stainless steel flange / ball valveThe Precision digital temperature controller is with 51 segments programmable is built in the furnace with +/- 1C accuracy It is an ideal instrument for quenching test or temperature measurement.

Part 1

--Vacuum Tube Furnace Features
    ♦ Temperature uniformity: +/-1C (according to the heating chamber size)
    ♦ Control system: Microcomputer controlled, Easy to operate, programmable, automatic heating up, automatic
       heat preservation, automatic cooling.
    ♦ Tube adopt: High purity quartz tube as furnace tube  
    ♦ Stainless steel Metallic flanges sealing (Double rubber ring)
    ♦ Outside temperature of the furnace is close to room temperature
    ♦ Double-circuit protection
    ♦ Super refractory material, Excellent thermally resistant, High temperature resistant, Thermal shock resistant 
    ♦ There is convection grid in the chamber of furnace,and furnace internal air flow is easy to form the convective
       circulation,It is helpful for balance of furnace temperature,uniform temperature field.
    ♦ The whole furnace adopts the double liner structure,even if the temperature is as high as 1100C,furnace
        body surface still keep low temperature.
    ♦ The chamber of furnace adopts imported energy-saving materials,and energy consumption of the whole
        machine is only 1/3 of  the traditional electric furnace,energy conservation and environmental protection.
    ♦ Furnace body is equipped with output voltage and output current monitoring table that makes the condition of
       heating be clear.
--Vacuum Tube Furnace Application
   Vacuum Tube Furnaces are widely used in the fields as follows:
   metallurgy / ceramics/ glass / machinery / analysis test / semiconductor / science / research and so on.
