Overview

Multi functional muffle furnace is a type of furnace that uses high-quality vacuum fiber for good insulation effect, fast heating speed, significant energy saving and energy saving. It can be used for sintering, heating, thermal analysis, and heat treatment in enterprises and institutions such as coal, chemical, metallurgical, building materials, scientific research units, and college laboratories.

Product Details

Scope of application:

Multi functional muffle furnaceIt is a high-quality vacuum fiber furnace with good insulation effect, fast heating speed, significant energy saving and energy saving. It can be used for sintering, heating, thermal analysis and heat treatment in enterprises and institutions such as coal, chemical, metallurgical, building materials, scientific research units and laboratories of colleges and universities. Meets the requirements of the national standard (GB212-2008).

Features:

Heat from both sides and the top three sides of the furnace to ensure uniform temperature distribution. The double-layer furnace shell structure is stable; The furnace shell is made of high-quality cold plate and stainless steel plate materials with electrostatic spraying. The use of high-quality vacuum fiber furnace has good insulation effect, fast heating speed, significant energy saving and energy-saving. Compared with traditional muffle furnace, it saves 1/2 of time and 2/3 of electricity. Can be used to quickly determine the ash content and volatile matter of coal, and fix carbon.

prolonged useMulti functional muffle furnaceVarious problems may arise, requiring us to repair the equipment. As we all know, the repair environment is poor, and many repair operations are carried out inside the furnace. The space is very crowded, with insufficient natural lighting and poor ventilation conditions. Workers are not only affected by dust during operation, but sometimes also directly exposed to high temperatures, smoke, toxic gases, and corrosion from chemical materials. Some furnaces can reach heights of up to 10m-20m, and due to the narrow site of the furnace body, repair work involves high-altitude three-dimensional intersections and multi-layer operations, which pose great risks.

Daily maintenance methods:

1. When used again after long-term disuse, an oven must be dried. The baking time should be between 200 ℃ and 600 ℃ for four hours. When in use, the furnace temperature should not exceed the rated temperature to avoid burning out the electric heating elements. It is prohibited to pour various liquids and easily soluble metals into the furnace. Work below the maximum temperature of 50 ℃, as the furnace wire has a longer lifespan.

2. The equipment and controller must operate in a location with a relative humidity not exceeding 85%, free from conductive dust, explosive gases, or corrosive gases. When metal materials containing oil or grease need to be heated, a large amount of volatile gases will affect and corrode the surface of the electric heating element, causing it to be destroyed and shorten its lifespan. Therefore, timely prevention and proper sealing of containers or appropriate openings should be taken during heating to eliminate the problem.

3. The controller should be limited to use within the ambient temperature range of 0-40 ℃.

4. According to technical requirements, regularly check whether the wiring of the electric furnace and controller is in good condition. The thermocouples connected to the controller may cause interference to the controller, resulting in phenomena such as jumping of display values and increased measurement errors. The higher the furnace temperature, the more obvious this phenomenon becomes. Therefore, it is necessary to ground the metal protective tube (housing) of the thermocouple well, and if necessary, use a three wire output thermocouple. In short, all effective measures should be taken to reduce interference.

5. Do not suddenly pull out the thermocouple at high temperatures to prevent the jacket from exploding.

6. Regularly keep the furnace clean and promptly remove oxides and other substances inside the furnace.

7. During use, when melting samples or burning precipitates with alkaline substances in the furnace, the operating conditions should be strictly controlled. A layer of refractory plate should be pre laid at the bottom of the furnace to prevent corrosion of the furnace.
