Abstract
The utility model discloses a lining heat preservation material for an electric calcination furnace, which mainly comprises a first layer of heat preservation cotton, a second layer of light clay heat insulation bricks, and a third layer of high-alumina firebricks, and is structurally characterized by further including a fourth layer of metallurgical coke powder and a fifth layer of carbon bricks. The lining heat preservation material for the electric calcination furnace has the advantages of high resistance to high temperature (greater than 2300 DEG C), and low electric conductivity.
Description
Technical field
The utility model relates to a kind of insulation material of Industrial Stoves, specifically relates to a kind of inner lining as thermal insulation material of electric forge furnace.
Background technology
At present, electric forge furnace is the Industrial Stoves as electric calcined anthracite or petroleum coke, and anthracite or petroleum coke reduce its sulfur content and resistivity etc. through the calcining of electric forge furnace.The inner lining as thermal insulation material of general electro-forge stove is a heat-preservation cotton for the ground floor that contacts with electric forge furnace furnace wall, and the second layer is a lightweight clay insulating brick, and the 3rd layer is alumina firebrick, and this layer and the product of being calcined contact.The electric forge furnace temperature of this inner lining as thermal insulation material structure is the highest can only to reach 1700-1800 ℃, thereby makes the product index of calcining not reach its intended purposes.Use such inner lining as thermal insulation material; Conductance is high, and electric current does not effectively produce heating to product, and electric current directly forms the loop through inner lining material; Product temperature is difficult to bring up to the graphitization requirement, and not only power consumption is big but also the easy liner tile that burns out stove in the utmost point short time.
The utility model content
The task of the utility model provides the electric forge furnace inner lining as thermal insulation material that a kind of high temperature resistant temperature is high, conductance is low.
For realizing above-mentioned task, the technical solution of the utility model is:
A kind of inner lining as thermal insulation material of electric forge furnace, main heat-preservation cotton by ground floor, the lightweight clay insulating brick of the second layer, the 3rd layer alumina firebrick constitutes, and said inner lining as thermal insulation material is a metallurgical coke for the 4th layer, and layer 5 is a brick fuel.
It is high to the utlity model has high temperature resistant temperature, and temperature can reach more than 2300 ℃, the advantage that conductance is low.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1, a kind of inner lining as thermal insulation material of electric forge furnace, mainly by the heat-preservation cotton 1 of ground floor, the alumina firebrick 3 that the lightweight clay insulating brick of the second layer is 2, the three layers constitutes, and its 4th layer is metallurgical coke 4, and layer 5 is a brick fuel 5.
Brick fuel is by three grades of metallurgical cokes (fixed carbon is more than 98%), and bonding agent is a resin, adopts powerful kneading machine to mix after the additive mixed in hydrochloric acid and pinches, and dries in the air behind the material, and with 350 tons of hydraulic forming machine vibration mouldings, roasting makes in roaster then.
Claims (1)
1. the inner lining as thermal insulation material of an electric forge furnace comprises the heat-preservation cotton of ground floor, the lightweight clay insulating brick of the second layer, and the 3rd layer alumina firebrick is characterized in that: the 4th layer is metallurgical coke, and layer 5 is a brick fuel.
