Problems solved by technology

However, the materials used in commonly used high-temperature refractory linings and thermal insulation linings have a large thermal conductivity. Therefore, the higher the design temperature of the furnace, the thicker the total thickness of the spherical refractory lining, and the larger the heat capacity. Therefore, the experimental electric furnace produced by the prior art The heating rate is slow and the energy saving effect is very limited

Embodiment 1

[0025] like figure 1 , 2 As shown, an energy-saving furnace mold with air heat insulation and heat radiation reflection layer is composed of refractory lining 1, air heat insulation layer 2, heat insulation layer 3, furnace top 4-1 and furnace bottom 4-1. The refractory lining 1 can be divided into three layers 1-1 superimposed and formed, and is located between the furnace top 4-1 and the furnace bottom 4-2. The insulation layer 3 is formed by combining two semicircular sheets 3-1 and 3-2, and wraps the refractory inner lining 1, the furnace top 4 and the furnace bottom 5 into one. Open a groove along the inner circumference in the middle of the inner concave surface of the insulation layer 3, the thickness of the groove is 10mm, and the height of the groove is consistent with the height of the refractory lining 1. The inner groove of the thermal insulation layer 3 and the outer side of the refractory inner lining 1 form the air heat insulation layer 2 . Glass microspheres...

Abstract

The invention discloses an energy-saving hearth provided with an air thermal insulating layer and a thermal radiation reflecting layer and a preparation method thereof. The energy-saving hearth is composed of a refractory lining, the air thermal insulating layer, the thermal radiation reflecting layer and a thermal insulating layer from inside to outside, wherein the refractory lining is preparedfrom ceramic fiber or / and graphite fiber or / and hollow ceramic microspheres through pouring or die-casting forming method;and the thermal radiation reflecting layer is composed of a metal polishing plate with the infrared ray total reflection capacity, a glass pane film coating plate, and a ceramic microsphere coating. According to the energy-saving hearth, the air thermal insulating layer and thethermal radiation reflecting layer are arranged between the refractory lining and the thermal insulating layer, so that thermal radiation and loss of heat conduction energy of the energy-saving hearth to the outside world are reduced to the maximum, and the energy-saving effect is remarkably improved. The preparation method of the energy-saving hearth is simple in technology, and the combined structure is convenient to maintain and can prolong the service life.

Description

technical field [0001] The invention relates to the production field of an energy-saving experimental electric furnace, in particular to an energy-saving furnace with an air heat insulation and heat radiation reflection layer and a preparation method thereof. Background technique [0002] The known energy-saving experimental electric furnace furnace is mainly composed of two parts: a high-temperature refractory lining and a thermal insulation lining. The high-temperature refractory lining is usually processed by high-temperature ceramic fiber board or vacuum molding of high-temperature ceramic fiber; the heat-insulating furnace lining is usually processed by medium-temperature ceramic fiber board or ceramic fiber felt. However, the materials used in commonly used high-temperature refractory linings and thermal insulation linings have a large thermal conductivity. Therefore, the higher the design temperature of the furnace, the thicker the total thickness of the spherical ref...
