What is the material used for the lining of the піч опору коробчатого типу

The electric furnace shell of box-type resistance furnace is welded by steel plate and section steel, and the bottom of the furnace body is connected with the light rail of the trolley as a whole. The user of this box-type resistance furnace does not need basic installation and only needs to be placed on a flat concrete floor for use.

The furnace lining adopts a full-fiber structure, which saves about 60% energy compared to the brick furnace. It uses high-quality long-fiber thorn blanket as raw material. According to the furnace size of the box-type resistance furnace, special equipment is used to make the specifications of a large plate, and a certain amount is left in the processing process. The amount of compression is to ensure that after the module is built, each ceramic fiber block expands in different directions, so that the modules are squeezed into a gapless whole to achieve a perfect heat storage effect, and the product construction is convenient and fast, and can be directly Fixed on the stainless steel anchor round nail of the furnace shell steel plate. Compared with other products, the advantages are low thermal conductivity, low heat capacity, excellent corrosion resistance, excellent thermal stability, thermal shock resistance, and heat insulation. The anchors are set on the cold surface of the furnace to improve the high temperature strength of the fiber.

The heating elements of the box-type resistance furnace are made of high-temperature resistance alloy wire wound into ribbons and spirals. They are respectively hung on the furnace side, furnace door, back wall and the wire bricks of the trolley, and are fixed with high-alumina porcelain nails. concise.
