JINGQI SX2-18-10N integrated Box-Type Resistance Furnace

Overview of uses

The box-type Resistance Furnace, also known as the muffle furnace, is a periodically operated electric furnace. Used for sintering, heating and heat treatment in the laboratories of coal, electric power, chemical industry, building materials, metallurgy, scientific research and other units and colleges and universities, especially suitable for coal quality analysis and testing, in the determination of coal ash and volatile matter and the analysis of coal ash composition, preparation of samples for determining ash melting point and ash viscosity, etc., muffle furnace burning samples and precipitates are widely used.

Features

Series Resistance Furnace, muffle furnace adopts domestic (CN) professional technology, the furnace shell is made of good steel plate through folding and welding, and the control box and the furnace body are integrated structure. The appearance is beautiful, which avoids the cumbersome installation of customers. The inner furnace lining is a rectangular integral furnace lining made of high alumina and silicon carbide refractories. The spiral-shaped heating element, made of iron-nickel-chromium-aluminum alloy wire, is threaded in the wire grooves on the upper, lower, left and right sides of the inner furnace lining. The maximum temperature of the furnace wire is 1000 degrees. Heat up, down, left, right. The furnace is a sealed structure, and the refractory fiber aluminum silicate cotton and diatomaceous earth products are used as a thermal insulation layer between the inner furnace and the furnace shell. The temperature in the furnace is uniform.
