PRODUCT INTRODUCTION
Brief Introduction
Adopting advanced technologies and independently developed and manufactured, this is a new-type energy-saving and eco-friendly pit furnace. It features an advanced and reasonable structure with an elegant and neat appearance. The outer shell is made of high-quality cold-rolled steel plates processed by high-precision CNC machine tools, and finished with imported two-color epoxy powder electrostatic spraying, which is high-grade and aesthetic.
The furnace boasts excellent high temperature resistance and corrosion resistance. Equipped with premium heating elements and an air cooling system between double-layer furnace shells, it achieves rapid cooling. It also delivers uniform temperature field, low surface temperature of furnace body, fast heating and cooling speed and outstanding energy-saving performance.
The furnace chamber is constructed with imported composite alumina fiber materials via numerical control technology, featuring strong thermal shock resistance, good corrosion resistance, no collapse, crystallization, slag falling or pollution, and long service life.
Its control system adopts microcomputer intelligent regulation technology, supporting PID regulation, automatic control and self-tuning functions as well as multi-section program programming to set various heating, heat preservation and cooling curves with high temperature control accuracy. It applies integrated module silicon controlled rectifier control and phase-shift triggering.
It is equipped with comprehensive protection devices including independent over-temperature protection, over-pressure, over-current, electric leakage and short-circuit protection. With high degree of automation, all technical indicators have reached advanced industry standards.
