Set research and development, production, sales, service as one of the formal electric furnace manufacturing base

Safety type high temperature frit furnace lyl-20r

Product parameters

Safety type frit furnace lyl-20r series high-temperature energy-saving precision frit furnace introduces advanced technology, independent research and development of energy-saving, environmental protection, new electric furnace, with advanced and reasonable structure, beautiful appearance, high-quality cold-rolled steel shell, processed by advanced CNC machine tool, Haohua, beautiful two-color imported epoxy powder electrostatic spraying process, processed, high-temperature resistant, resistant to high temperature The furnace has the advantages of balanced temperature field, low surface temperature, fast temperature rise and fall, energy saving and so on. The furnace is made of imported composite alumina fiber material by numerical control technology. It has strong thermal shock resistance, good corrosion resistance, no collapse, no crystallization, no slag, no pollution and long service life. The control system adopts microcomputer artificial intelligence regulation technology, with PID regulation, automatic control, self-tuning functions, multi-stage programming, and can program various heating, heat preservation and cooling procedures, with high temperature control accuracy; integrated module silicon controlled rectifier control, phase-shifting trigger, protection system: independent over temperature protection, overpressure, over current, leakage, short-circuit protection. The degree of automation is high, and the indexes have reached the advanced level.

This equipment is widely used in the experiments and production of powder, electronics, metallurgy, medicine, ceramics, new materials, chemical industry, metal sintering and metal heat treatment, etc.
