Rotary Kiln LYL-XGYL8068

     The rotary kiln LYL-XGYL8068 is a high-efficiency, energy-saving, environmentally friendly, and innovative electric furnace, developed and produced in-house by introducing advanced foreign technology. It features a sophisticated and rational structure with an aesthetically pleasing appearance. The exterior casing is made of high-quality cold-rolled steel plate, processed by advanced CNC machine tools, and finished with a luxurious, durable two-tone imported epoxy powder electrostatic spray coating, offering high-temperature resistance and corrosion resistance. It utilizes high-quality resistance wire as heating elements and a double-layer shell with air insulation, resulting in a low surface temperature. The furnace offers advantages such as a uniform temperature field, adjustable heating, holding, and cooling rates, and energy efficiency. The entire furnace chamber is constructed from alumina polycrystalline fiber material using a unique CNC process, providing excellent thermal shock resistance, rapid heating/cooling tolerance, corrosion resistance, resistance to collapse and crystallization, no pollution, and a long service life. The control system employs microcomputer-based AI regulation technology, featuring PID adjustment, automatic control, and auto-tuning functions. It supports multi-segment programmable profiles for various heating, holding, and cooling steps, ensuring high temperature control accuracy. It utilizes integrated thyristor modules and phase-shift triggering. The protection system includes independent over-temperature, over-voltage, over-current, leakage, and short-circuit protection. The equipment boasts a high degree of automation, with all key indicators meeting advanced standards.

This equipment is widely used in higher education institutions, research institutes, and industrial/mining enterprises for experiments and production involving powder, electronics, metallurgy, pharmaceuticals, ceramics, glass, new materials, chemical industry, metal sintering, and metal heat treatment.
