Stainless Steel Lined Vacuum Atmosphere Pit Furnace LYL-20JLU

Brief Introduction

The Stainless Steel Lined Pit Furnace LYL-20JLU is a new generation of energy-saving, environmentally friendly electric furnace developed through independent R&D, incorporating advanced technology. It features a sophisticated, rational structure and an aesthetically pleasing appearance. 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 wire, 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, full 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.
