We are known in the industry for our range of electric muffle furnace that is precision engineered to give solutions to laboratories and industrial applications. These muffle furnaces find usage in engineering tests of soils & aggregates, cement testing, ashing organic and inorganic samples, gravimetric analysis and ignition tests. To meet the diverse requirements of our clients, we offer these heaters in various ranges at most competitive prices A muffle furnace (sometimes, retort furnace) in historical usage is a furnace in which the subject material is isolated from the fuel and all of the products of combustion including gases and flying ash. After the development of high-temperature electric heating elements and widespread electrification in developed countries, new muffle furnaces quickly moved to electric designs. Today, a muffle furnace is (usually) a front-loading box-type oven or kiln for high-temperature applications such as fusingglass, creating enamel coatings, ceramics and soldering and brazing articles. They are also used in many research facilities, for example by chemists in order to determine what proportion of a sample is non-combustible and non-volatile (i.e., ash). Some digital controllers allow RS232 interface and permit the operator to program up to 126 segments, such as ramping, soaking, sintering, and more. Also, advances in materials for heating elements, such as molybdenum disilicide offered in certain models by Vecstar, can now produce working temperatures up to 1800 degrees Celsius, which facilitate more sophisticated metallurgical applications. The term muffle furnace may also be used to describe another oven constructed on many of the same principles as the box type kiln mentioned above, but takes the form of a long, wide, and thin hollow tube used in roll to roll manufacturing processes.

An annealing furnace is a piece of equipment used to heat a material at very high temperatures, to change its hardness and strength properties. Annealing is commonly associated with the manufacture of steel, to relieve internal stresses that may lead to failure in service and to produce a more uniform, or homogeneous, internal structure. This process is also commonly used with various metals, glass, and other materials to make them less brittle and more workable. For metals, an annealing furnace must be capable of heating the material to a specific temperature, known as the re-crystallization temperature. This produces changes in the atomic structure and causes the metal to soften. While annealing temperatures vary depending on the material and application, a typical temperature for annealing steel is around 1,292°F (700°C). An annealing furnace is designed for very uniform heating, followed by a gradual cooling process. To prevent oxidation of the material, the heating chamber is airtight, with a slightly positive pressure. The atmosphere within the chamber typically consists of a combination of nitrogen and hydrogen. The two primary types of annealing furnace are: Batch Continuous. Batch Furnace: In a batch furnace, single or multiple stacks of coils are usually placed on a fixed base inside the heating chamber. Continuous Annealing Furnace: A continuous annealing furnace will heat a material as it moves along a conveyor, or on a rotating hearth. A coil of material is unwound, treated as it moves through the furnace, and then rewound. The annealing process can take 15 minutes to several hours, depending on the type of material, treatment application, and size of the coils. Natural gas is commonly used as heating fuel in an annealing furnace. A series of burners are located around the inside surface of the heating chamber. A fan is often used to circulate and convey the heat around the material being annealed. Most modern annealing furnaces use a computer system to control the natural gas supply, to monitor and analyze conditions inside the heating chamber, and to drive motors and other mechanical equipment used to convey the annealing material. The heating chamber is designed to maintain a high degree of temperature accuracy and uniformity as the material is heated. An annealing furnace can be purchased in a wide variety of sizes, and with a range of capabilities. Units are manufactured for laboratory and small-scale applications, to very large furnaces like those typically used in steel foundries. Annealing furnaces have become more efficient in recent years due to innovations, such as improved chamber designs and seals to reduce escaping heat and emissions; better control of temperature and treatment uniformity; combined natural gas and electric heating for higher efficiency; and improved process controland monitoring capabilities.
