This High Temperature Box Furnace, with its ultra-large 125L capacity and a maximum temperature of 1700℃, is an industrial-grade laboratory furnace that is becoming a powerful tool for numerous university laboratories, research institutes, and industrial enterprises in overcoming the challenges of high-temperature material preparation.

In materials science research, metal processing manufacturing, and third-party testing institutions, the preparation of metallographic samples is a crucial step before microscopic analysis. For many busy laboratories, sample mounting is often a bottleneck in efficiency. Traditional manual or single-station mounting machines are not only time-consuming but also highly dependent on the operator's skill, easily leading to inconsistent sample preparation quality and even rework in subsequent grinding and polishing steps due to human error.

In the daily work of materials laboratories, we often face a tricky dilemma: the need to perform heat treatment or coating on ultra-thin samples (such as crystals, semiconductor wafers, and fuel cell substrates) in a high-temperature environment (300℃-500℃), but traditional mechanical fixing methods can easily cause stress damage.

In laboratories, research facilities, and industrial settings, high-temperature heating equipment is essential for many heat treatment and materials research processes. The most common types of high-temperature furnaces are laboratory tube furnaces and box furnaces. They differ clearly in structure, heating method, sample suitability, temperature control, and application areas. Understanding these differences makes it easier to choose the right furnace for specific experimental needs.

Common heating elements for a high temperature laboratory furnace​ include resistance wire, silicon carbide rods, and molybdenum disilicide rods. Each type has a different temperature tolerance, which directly affects the furnace’s safety and service life. To ensure long-term, stable operation, the recommended continuous working temperature is usually set lower than the element’s maximum temperature to avoid overheating and premature aging. When selecting a furnace, it is important to match the heating element and furnace specifications to both the required maximum temperature and the actual long-term operating temperature of the experiment.

In materials science research and industrial production, laboratories often face a dilemma: choosing a tube furnace to obtain excellent atmosphere protection and vacuum environment, or choosing a box furnace to achieve sintering of large-sized or large-batch samples?

In the field of materials science, the success of an experiment depends not only on the performance of a single piece of equipment, but also on the compatibility and smoothness of the entire experimental process. As a veteran brand established in 2000, Shenyang Kejing understands the pain points of scientific researchers: they need not only to buy equipment, but also to buy the right solution.

A Box Furnace is a common industrial heating device, typically used for heating materials such as metals, glass, and ceramics. In daily operation, it is necessary to calculate the power consumption of a Box Furnace in order to reasonably allocate electrical resources and control production costs. In this article, we will introduce the relevant formulas and methods for calculating the power consumption of a Box Furnace, hoping to provide helpful guidance.

Many people find it difficult to distinguish between a vibratory sander and a polishing machine. At first glance, both are used to treat the surface texture of materials, but in fact, the two types of equipment differ fundamentally in working principles, processing results, and application scenarios.

Before formally starting this article, let us first give a brief introduction to what a Polishing machine is. Simply put, a Polishing machine is a piece of equipment used to polish and restore the surfaces of objects. It is equipped with a high-speed rotating polishing disc and is convenient and efficient to use. However, due to its high-speed operating principle, there are certain safety risks during operation. Therefore, personnel who operate this equipment must strictly follow the safety specifications below to ensure safe operation.

A laboratory box furnace is primarily used for hightemperature sintering, metal annealing, quality inspection, and similar applications in universities, research institutes, and industrial enterprises. Its core principle involves generating heat by passing an electric current through heating elements, creating a uniform hightemperature environment within an enclosed chamber lined with refractory materials, thereby meeting various heat treatment needs.

A muffle furnace, also known as a box furnace or vacuum furnace, is a heating device designed to operate under hightemperature and highpurity atmospheric conditions. It is commonly used in laboratory environments for sample pretreatment, elemental analysis, and experiments involving special materials. This type of furnace is characterized by precise temperature control, adjustable atmosphere, simple operation, and safe use, making it widely applicable in fields such as materials science, chemistry, and electronics. As a hightemperature heating instrument, muffle furnaces can typically reach temperatures of 1000℃ or even 1300℃. Our compact lab muffle furnace, however, can achieve temperatures up to 1750℃, meeting the experimental needs of highmeltingpoint and highstability materials, and providing critical technical support for materials research and sample processing.
