Precautions for Using a 1200 Tube-Type Electric Furnace, Single-Phase 220V
Read the product manual before use. The user’s power distribution system must be compatible with the operating requirements of the electric furnace. This electric furnace requires a single-phase 220 V power supply; the distribution wiring shall use copper conductors with a cross-sectional area of no less than 4 mm², and the circuit breaker on the distribution panel shall have a rating of no less than 32 A. The electric furnace enclosure must be equipped with reliable protective grounding or protective earthing.

Zhonghuan Electric Furnace Proudly Launches the High-Temperature, High-Speed Water-Oxygen Environment Corrosion Tester
Tianjin Zhonghuan has launched a new product: a high-temperature water–oxygen environment corrosion tester (static mode) with a high degree of integration and a maximum operating temperature of 1,600°C. The flow rates of both gas and water vapor are stable and precisely controllable, with current options ranging from 30–300 mL/min to 100–1,000 mL/min. By employing experimental testing methods, this instrument accurately simulates the extreme service environments experienced by alloys and coatings in turbine engines and gas-fired steam turbines, conducting cyclic tests on thermal corrosion and steam oxidation corrosion to reliably evaluate the thermochemical stability of materials.

Central atmospheric box-type electric furnace—powering your research and production endeavors.
In fields such as materials science, metallurgy, ceramic manufacturing, and new energy, atmosphere box-type electric furnaces are emerging as a key driving force behind industry advancement thanks to their outstanding performance. Precise temperature control, consistently stable: Equipped with an advanced temperature-control system, these furnaces maintain stable temperatures even under high-temperature conditions, with a temperature-control accuracy of ±1°C. They are perfectly suited for applications ranging from materials research and chemical engineering—where high-temperature environments are essential—to semiconductor manufacturing and electronic-component testing, which demand extremely high temperature precision. Flexible atmospheres, fully customizable: Featuring a professional atmosphere-control system, these furnaces can introduce various gases—including nitrogen, argon, and hydrogen—into the furnace chamber as needed, allowing precise control over the atmospheric composition. This enables a wide range of heat-treatment processes, such as gas carburizing, carbonitriding, bright quenching, annealing, and normalizing, while effectively preventing undesirable reactions like oxidation and corrosion during high-temperature processing, thereby ensuring stable and reliable improvements in material properties.

Structural Features, Usage Precautions, and Maintenance of Electric Forced-Air Drying Ovens
The structural design of electric forced-air drying ovens typically features the following salient characteristics: 1. Outer Shell and Inner Chamber: The outer shell is generally fabricated from high-quality cold-rolled steel sheet and undergoes an electrostatic powder-coating process, resulting in a modern, aesthetically pleasing appearance as well as excellent corrosion resistance. The inner chamber is constructed from stainless steel or cold-rolled steel that has been subjected to anti-corrosion treatment, ensuring a clean and durable internal environment. 2. Door Design: The oven door is usually top-hinged for ease of operation. A glass observation window is installed in the center of the door, allowing users to monitor the status of the items being heated inside at any time. A high-temperature-resistant sealing gasket is embedded around the door frame, providing excellent air tightness and effectively preventing heat loss.

Characteristics and Application Analysis of Box-Type Resistance Furnaces
Box-type resistance furnaces are a common type of electric furnace, available in vertical, horizontal, split, and monolithic configurations. Temperature ranges include 1,000°C, 1,200°C, 1,300°C, 1,600°C, and 1,800°C, with resistance wires, silicon carbide rods, and silicon-molybdenum rods serving as heating elements; the choice depends on specific application requirements. In addition to conventional air-atmosphere heating, box-type furnaces can also be equipped for controlled-atmosphere operation or vacuum sealing, offering a wide variety of configurations. They are extensively used in production and research across such fields as ceramics, metallurgy, electronics, glass, chemical engineering, mechanical engineering, refractory materials, new-material development, specialty materials, and building materials.
