Description

A kind of industrial furnace

Technical field

The utility model relates to a kind of industrial furnace.

Technical background

In common industrial production, one hot-working, heat treatment step are arranged, be many industrial products manufacture processes must process, the key of this procedure is an equipment, i.e. industrial furnace.The quality of industrial furnace quality directly influences the quality of product, and the quality height of burner hearth and furnace wall in the stove is again the leading indicator of dividing the industrial furnace quality.For a long time, the groundwork of industrial furnace partly is a burner hearth, and the various refractory brick of the general employing of the furnace wall of burner hearth are as common brick, schamotte brick, corundum brick, silica brick, magnesia brick, high-alumina brick, light fire brick etc.; Perhaps use various types of castable refractories, light weight castable refractory, fire-resistance rammed mass and plastic refractory, these refractory materials all are classical furnace building materials, generally use in various industrial furnaces, as steel rolling soaking pit, heating furnace, annealing furnace, annular furnace, building materials tunnel cave, down-draft kiln, chemical petroleum stove, machined heat-treatment furnace etc.More than various materials different handling characteristics and advantage are arranged, but also come with some shortcomings, as in use, the stove brickwork joint is easily loosening, easy to crack, water the easy crackle of material feeding, easily peel off, and thermal conductivity factor height, the suction amount of stored heat is many, and heat-insulating property is poor, often needs maintaining, cause increase nonproductive man-hour, greatly influenced manufacturing schedule.Problems such as especially the process industry stove is not easy, and labour intensity is big, and the process-cycle is long, and cost is high are perplexing the stove industry always.

Summary of the invention

The purpose of this utility model just provides a kind of industrial furnace that overcomes above-mentioned prior art defective.

The utility model is realized by following approach; it contains body of heater, burner hearth and furnace wall; the surface of described furnace wall is fixed with the ceramic fiber blocks layer by the high temperature adhesives layer; the outer surface of ceramic fiber blocks layer is coated with paint adhesion auxiliary agent layer, and the surface of paint adhesion auxiliary agent layer is coated with the protective layer of high-temperature infrared complex liquid emulsified material.

Of the present utility model have operating temperature and reach 800-1600 ℃, high temperature resistance, and thermal conductivity factor is low, and thermal losses is little, and environmental thermal pollution is little, sufficient combustion, programming rate is fast, and energy consumption is low; Has good thermal shock resistance, anti-oxidant and corrosion resistance; But also have not easy to crack, incrust, from heavy and light, long service life, maintenance man-hours is few, labor productivity height, the characteristics that labor strength is low.
