The TCZQ series is an integrated molded high-temperature vacuum atmosphere furnace. The characteristic of an atmosphere furnace is that, at a given temperature, a prepared artificial atmosphere of a specific composition is introduced into the furnace to achieve certain heat treatment purposes, such as gas carburizing, carbonitriding, bright quenching, annealing, normalizing, etc. Atmosphere furnaces mainly have the following features: Sealing—to control the atmosphere inside the furnace and maintain the internal pressure, the working space within the furnace must always be isolated from the outside air, minimizing gas leakage and air intake as much as possible. Therefore, the furnace shell, masonry, furnace door, and all externally connected components such as fans, thermocouples, and heating elements must be equipped with sealing devices; Atmosphere control—to maintain a certain carbon potential inside the furnace, in addition to ensuring the stability of the atmosphere composition, automatic control of the furnace atmosphere is also required. Hence, various control instruments need to be installed to continuously or periodically measure and adjust the gas supply within the furnace.
▪ LED large-screen LCD display. This unit is equipped with a vacuum pump and an internal circulating water cooling system, eliminating the need for an external water source, keeping the external surface temperature lower, and offering an elegant appearance with simple operation.
▪The heating system, gas mixing system, vacuum system, internal circulating water cooling system, and monitoring system of this product can all be operated via control buttons. This machine is fully functional and meets most customer requirements.
▪ Professional vacuum design and unique sealing technology ensure the airtightness of the cranial cavity, with a vacuum level far exceeding that of similar products.
▪ Intelligent PID high-precision control with self-tuning function, 30-segment programmable control, allowing the setting of 30 heating and cooling programs, achieving power lossless operation.
▪ Optional 485 conversion interface for connection with a computer. An optional dedicated computer control system can be used to achieve remote control, real-time tracking, historical records, output reports, and other functions for a single furnace or up to 200 furnaces.
▪ Heating elements: 1200°C, 1400°C, 1700°C, made of high-quality high-resistance alloy wire OCr27FAI7Mo2, high-quality silicon carbide rods, and high-quality silicon molybdenum rods. **The heating temperature can reach 1200°C, 1400°C, and 1700°C.
▪Fast heating speed with adjustable heating rate: Max: 30°C/min
▪Low thermal pollution: The furnace uses domestic new high-purity alumina microcrystalline fiber insulation material, with fan cooling between the double-layer shells, enabling rapid cooling of the furnace surface and keeping the outer shell cool to the touch.
▪Precise temperature control, with a variety of temperature controllers available for selection, and minimal temperature fluctuation (temperature control accuracy ±1°C). The vacuum level **can reach 0.1 MPa, and the positive pressure can reach 0.09 MPa.
