Smelting furnace structure Silicon carbide smelting furnace mainly has the following parts: end wall, electrode, hearth, side wall and pillar, end wall The end walls are located at both ends of the hearth, in which the electrodes are installed. The end wall is a part of the material holding volume, and supports and protects the electrode from oxidation. It is required that the end wall has a firm structure, high temperature resistance and oxidation resistance, and does not tilt outward or deform under the thermal expansion pressure of the charge. It is also required to be airtight to prevent electrode oxidation. Usually the end walls are made of refractory bricks (or prefabricated concrete), carbonaceous masonry, and fastened with steel frames. If concrete prefabricated parts are used, they are generally built in the external low temperature parts. There are many types of carbon masonry. There are also those that use charge instead of carbonaceous masonry. This structure saves carbonac

Melting furnace oven process All newly repaired or small and medium-sized furnaces need to be baked before production and use in order to remove the moisture in the furnace.

Muffle Furnace Precautions 1. When the muffle furnace is used for the first time or is used again after long-term use, it must be oven-baked. The oven time should be from room temperature to 200°C for four hours, and from 200°C to 600°C for four hours. When using, the maximum furnace temperature should not exceed the rated temperature, so as not to burn the electric heating element. It is forbidden to pour various liquids and easily soluble metals into the furnace. The muffle furnace is best to work below the maximum temperature of 50 °C, and the furnace wire has a longer life. 2. The muffle furnace and controller must work in a place where the relative humidity does not exceed 85%, and there is no conductive dust, explosive gas or corrosive gas. When the metal material with grease and the like needs to be heated, a large amount of volatile gas will affect and corrode the surface of the heating element, destroying it and shortening its life. Therefore, when heating, it should be preven

Installation and Use of Muffle Furnace 1. After opening the package, check whether the muffle furnace is intact and whether the accessories are complete. General muffle furnace does not need special installation, just lay flat on the floor or shelf indoors. The controller should avoid vibration and should not be placed too close to the electric furnace to prevent the internal components from not working properly due to overheating. 2. A thermocouple is inserted into the furnace for 20-50mm, and the gap between the hole and the thermocouple is filled with asbestos rope. It is best to use compensation wire (or insulated steel core wire) to connect the thermocouple to the control, pay attention to the positive and negative poles, do not connect them in reverse. 3. An additional power switch needs to be installed at the introduction of the power cord in order to control the main power supply. In order to ensure safe operation, the electric furnace and the controller must be reliably ground

Electric Heating Boiler Electric heating element There are many types of electric heating boilers, and their classification is generally divided according to the form of electric heating elements, including resistance type, electrode type and electric film type. Resistive The resistance type adopts a high-impedance tubular electric heating element. After the power is turned on, the tubular electric heating element generates high heat to turn the water into hot water or steam. The tubular electric heating element is composed of a metal shell, an electric heating wire and an oxidation continuation. The advantage of this element is that the water is not charged, the use is relatively safe, and the water quality is not polluted. The problem is that the increase of boiler capacity is realized by the number of tubular electric heating elements, and the boiler load is adjusted according to the number of put into operation. Therefore, the capacity of this boiler is limited by the structural ar
