The chamber furnace product description and safety technical regulations

Used for heating before forging the metal billet or ingot. Heating the material does not move; non-segmented furnace temperature uniformity throughout the for large ingot heating periodic temperature regime (ie the oven time is divided into warm-up period, the heating of the soaking period). There are two types: fixed hearth chamber furnaces and car bottom furnace chamber furnace.
Technical specification for safety:
1, safe, all furnace must have the following components and safety facilities. The outlet temperature of the automatic adjusting means; the feedstock oil automatic control means; furnace, convection, furnace tubes, radiation, temperature indication of the flue;
Population and superheated steam pressure gauge furnace; damper and flue baffle; emergency venting devices; blast doors; hearth and back elbow tank fire steam line.
3. The new furnace according to prescribed procedures must be put into use, the heating curve Ovens.
4. Hearth chamber furnace ignition off good hole, the flue baffle opening to 1/3 1/2, fuel oil systems circulation and circulation of raw materials, ready to soak diesel ignition stick.
5. Ignition steam furnace residue gas rush the net, on the upper end of the burner will ignite ignition rods, others to leave the bottom of the furnace, steam slightly open, and then open the oil line. Point fuel fire, regulate oil and gas than to a normal state.
6. Cited gas off the net water storage and condensed oil and drained in a safe place for more than 15 minutes, the laboratory analysis of the oxygen content of less than 1%, before the vote with the ignition. Gas into the blast furnace must pass the flame arrester.
7. Ignition fireman can not face the fire mouth and see the fire window to avoid tempering wounding. If the flame goes out, the fuel valve should be closed immediately, the furnace domestic demand steam purge in order to re-ignition.
8. Normal operation should always check the stove burning at any time to adjust, pay attention to check whether the tube bending, bubbling, peeling, redness and dark abnormal situation, pay attention to check back elbow, plug, entrances valve flange seamless oil phenomenon, abnormal, and immediately reported to the leadership, to take measures to deal with.
Case of burn-through caused by a ruptured tube furnace of fire or an emergency need into the furnace, the application of steam to put out the fire cooling treatment, no water is injected into the furnace for fire fighting and cooling.
10 into the furnace overhaul should handle into the equipment and operating procedures. Explosion-proof doors shall not be blocked with other objects, so as not to lose the explosion-proof effect.
11. Furnace heating or shutdown cooling must be strictly in accordance with the provisions of the heating and cooling rate.
12 emergency shutdown, against only wind instrument used to close the control valve, be sure to close the blast furnace hand valve.
(13) In case of the heating medium interrupts should immediately fire the furnace pass into the steam.
