The dust inside furnace compares coal fired annealing furnace big, use the means that mechanical coal fired heats secondhand, can reduce furnace inside of big grain dust invade, law of this kind of combustion is to belong to aerification of half dirty coal to burn. The dust immerge of coal fired arrives fireproof fiber surface, without intense chemical reaction, the combustion of coal and formation atmosphere, cannot make the appearance that accelerates to fireproof fiber crystallization. Coal ash dust will be adsorptive a compact layer is formed in fibrous surface. Coal fired annealing furnace is shown 1 times like the graph.

This furnace is the strip steel anneal that coils of strip steel inside protective canister, high annealing temperature 1150 ℃ , via two years the fireproof fiber on much moving fiber furnace lid does not have break, furnace warms up rate is rapid. Check via academy of heat energy of former metallurgy ministry, the CO content in flue gas giving heat is 0, more energy-saving than former furnace 15% , furnace ton steel specific power consumption (standard coal) index 70.13kg.

This furnace roof is complete fiber compound roof is flat-roofed structure, divide into 7 installation in all, in construction the spot or structural manufactory can install fireproof fiber line directly. After by blueprint dimension armor plate the lid has been made, also can install fireproof fiber in the manufactory. Roof cent is unit piece to make installation, was close to heat treatment furnace the craft of fast stack mounting. To the heat treatment furnace of big span, but flat-roofed structure condole hangs direct make it, washed out firebrick build by laying bricks or stones to build the complex course of vault, not only maintenance is convenient, construction cycle is very short also. Means of fireproof fibrous installation is crucial to service life, if the graph is shown 2 times,the fireproof fiber of this furnace installs means, in felt of aluminous fiber of general of three-layer of tile of roof cover board, every should stagger aperture is spread, the fireproof fiber felt of tile crosses anchor after solid board, the local fiber that is worn to defeat wants raised, for tall aluminous fiber the space is not had between installation hind and tile fiber, in installation so tall aluminous fiber stands when, the part with tile raised fiber again new planish. Working layer uses tall aluminous fiber to cut, ply of working layer need is cut namely width. Cut should intensify with special fixture, after refractory steel is being waited for to wear lever to be worn after putting installation position, open clamping apparatus again, be helpful for fireproof fiber be being pressed more closely so.

This kind of fireproof fiber installs means, refractory steel spreads firm staff length to want moderate, the metal is anchorage solid board solders before furnace lid armor plate, should wear first originally in anchor after going up, lever solders again, anchorage firm staff in anchor solid board internal energy turns at will for qualification.
