During operation, a high temperature box furnace may experience abnormal furnace pressure, seriously affecting normal operation. Symptoms of abnormal furnace pressure include unstable combustion, a smaller or larger flame, and increased noise. There are many causes, and this article describes some common solutions.

High temperature laboratory furnaces are easy to operate: equipped with a clear control panel (knobs, buttons, or touchscreen), and some models support PLC control. Multiple safety features: Overtemperature alarm and power-off protection: Automatically alarms and shuts off the heating power when the temperature exceeds the set value;

Sandpaper is not recommended for routine cleaning of tube and box furnaces, as it may scratch the furnace surface, affecting performance and lifespan. The correct cleaning method involves using a soft cloth or sponge with a dedicated cleaning agent.

1. Understand the temperature tolerance range of the material. Different materials have different high-temperature resistance properties. Excessively high temperatures can cause deformation, melting, or damage. Therefore, when setting the temperature of a high-temperature box furnace, you should refer to the material's temperature tolerance range to ensure that the selected temperature does not exceed this range.

Excessively rapid heating rates can lead to uneven temperatures within the material, causing uneven changes in the material's microstructure and affecting the accuracy of the experimental structure. For example, in the heat treatment of metal materials, excessively rapid heating rates can cause cracks or deformation, affecting the material's performance test results.

The SP-AM-400 4-head vacuum Lab Arc Melt Furnace is designed for temperatures of 25°C ± 15°C and humidity of 55% RH ± 10% RH. It requires a self-circulating cooling system with pure or deionized water, an AC 380V power supply, and an argon gas supply. Key specifications include an ultimate vacuum of 8 × 10-4 Pa, power consumption less than 60 kW, an operating pressure of -0.5 MPa, and a system vacuum leak rate of 5.0 × 10-7 Pa.l/s. The Lab Arc Melt Furnace features multiple safety features, including a molecular pump unit, a rotary melting crucible, and an argon arc welder. The Lab Arc Melt Furnace is tailored to specific process requirements.

The Small multifunctional coating machine is a laboratory device used to precisely apply functional coatings to various substrates. Using automated or semi-automated methods, it evenly applies liquid, slurry, colloid, or molten functional materials onto substrates of various materials, such as glass, metal, plastic, and film. The coating's thickness, uniformity, shape, and structure can be precisely controlled to meet the needs of scientific research experiments or small-scale trial production. So, do you know the applications of the Small multifunctional coating machine?

Demand from both domestic and international customers for efficient, precise, and stable equipment continues to rise. To address this need, our company has developed a new Plasma Thin Film Sputtering Instrument.

Small tube furnace is a kind of high-temperature experimental equipment with CE verification. It adopts a quick-connecting vacuum flange structure and a high-performance sealing ring, which allows one or both ends of the furnace tube to be quickly opened and closed, which facilitates the frequent picking and placing of samples and improves the experimental efficiency. The characteristic of small tube furnace is that it can work at temperatures up to 1200°C or in a vacuum environment. The furnace tube of small tube furnace can be configured as a 1-inch or 2-inch high-purity quartz furnace tube. The temperature control system of small tube furnace includes 30 heating and cooling curve settings, and its temperature control accuracy reaches +/-1°C. Small tube furnace is mainly used in scenarios that require high temperature and strict atmosphere, especially for the synthesis of materials in the laboratory, heat treatment, sintering and modification of battery materials, and catalyst research. High-temperature processes that require high efficiency and easy operation.

Single temperature zone tube furnace is a horizontally placed high temperature resistant furnace tube, and the material is placed in a heat-resistant container in the tube. In order to form a high temperature environment, there is usually a silicon-carbon rod heating element outside the furnace tube, so that the single temperature zone tube furnace can generate the heat required for the experiment. Single temperature zone tube furnace is managed by a temperature control system, which has a simple structure, easy operation and low cost.
