High Vacuum Openable Tube Furnace WLT-800GLZ

Brief Introduction

The High Vacuum Tube Furnace LYL-12FZGL is a new generation of energy-saving, environmentally friendly, and innovative electric furnace developed through independent R&D, incorporating advanced technology. It features a sophisticated and rational structure with a refined, aesthetically pleasing design. The outer casing is constructed from high-quality cold-rolled steel plate, processed by CNC machine tools, and finished with a premium, durable two-tone imported epoxy powder electrostatic spray coating, providing resistance to high temperatures and corrosion. High-quality resistance wires, silicon carbide rods, or molybdenum disilicide rods serve as heating elements. The double-layer furnace shell with an air insulation layer maintains a low surface temperature. The furnace offers advantages such as a balanced temperature field, low exterior surface temperature, adjustable heating rates, and energy efficiency. The furnace chamber is constructed from ceramic fiber material using a CNC process, ensuring excellent thermal shock resistance, tolerance to rapid heating and cooling, corrosion resistance, and is resistant to sagging, crystallization, and dusting, with no pollution and a long service life. The control system utilizes microcomputer-based artificial intelligence regulation technology, featuring PID adjustment, fully automatic control, and auto-tuning functions. It supports multi-segment programmable profiles for various heating and holding steps, achieving high temperature control accuracy. It employs integrated thyristor modules and phase-shift triggering. The protection system includes independent safeguards against over-temperature, over-voltage, over-current, leakage, and short circuits. The equipment boasts a high degree of automation, with all indicators meeting advanced standards.

The equipment features a pleasing appearance, rational design, and is simple and convenient to operate.

Product Features

• The casing employs a specially designed double-layer structure of high-quality cold-rolled steel plate, with a high-temperature baked paint finish for lasting durability.

  
  

• Air insulation provides benefits such as a balanced temperature field, low surface temperature, and fast heating rates.

  
  

• The specially designed vacuum system is easy to operate, achieves a high vacuum level, and has minimal leakage. It uses a molecular pump combined with a foreline pump (ultimate vacuum: 10⁻⁵ Pa).

  
  

• The sealing system utilizes stainless steel flanges, furnace tubes, and high-temperature resistant O-ring silicone rubber seals. Gas flow is regulated by a flow meter and needle valve. The valve control system includes inlet, outlet, and vacuum valves, allowing for the introduction of inert gases like nitrogen and argon.

  
  

• The furnace chamber is constructed from imported composite alumina fiber material using a special process, resulting in approximately 60% energy savings compared to traditional electric furnaces.

  
  

• The control system uses microcomputer-based AI regulation technology, supporting multi-segment programmable profiles for heating, holding, and cooling steps, with high precision. It features crystal modular thyristor control and phase-shift triggering, along with high-quality heating elements.

  
  

• The digital control panel includes protection functions against over-temperature, over-voltage, over-current, thermocouple break, and power failure.

Temperature Range: 1000°C, 1200°C, 1400°C, 1600°C, 1700°C, 1800°C (Selectable models).
