Ladle Refining Furnace

Ladle Refining Furnace is used to refine the molten steel from primary melting furnace (electric arc furnace, induction furnace, converter and etc.), meanwhile have the function of adjusting molten steel temperature, and be a buffer of the whole process. It is described to be soul of the best production line (primary melting furnace + LF+ CCM). It is widely used in refining all kinds of steel grade, such as ball bearing steel, alloy structural steel, tool steel, spring steel, carbon steel and etc.

Characteristic:

1. Even the molten steel composition and temperature
2. Desulfidation, degassing, deoxidation and removing non-metallic impurities.
3. Increase production capacity.

Adoption of new technology:

1. Tubular water cooled furnace lid
2. Electrode lifting mechanism ( single phase, three-phase)
3. Optimize large current system structure (energy-saving type)
4. PLC controller of electrode automatic lifting regulator
5. Automatic control argon blowing system
6. Frequency control ladle car
7. Industrial automatic control
8. Network technique

Q: Selection of heat preservation material for industrial furnace: Ceramic fiber blanket can be used.Ceramic fiber blanket color white, regular size, set fire, heat insulation, insulation in one. Free from any binding agent.

Q: Should the industrial furnace shell cool down?: The function of furnace shell is beautiful, protective lining, fixed function accessories and so on.

Q: What are the combustion equipments used in industrial boilers?: The main auxiliary equipments of the general boiler are: upper coal machine, ash blower, blower, draught fan, economizer, feed pump and water treatment unit. Oil boilers are: oil pumps, burners, tanks and so on.

Q: What is industrial furnace masonry?: Pre construction and recording shall be carried out on complex and important parts of industrial furnaces,masonry of all kinds of masonry shall be made with staggered joint masonry.

Q: Why does the burner of industrial furnace burn occasionally?: The flameout protection system is made up of burner controller, electromagnetic valve and flame detector, and the flame detection mode is mainly based on the two forms of ultraviolet detection and electrode detection. By utilizing the electric conductivity of the flame, the circuit path of the combustion process generates a weak current, and when the signal amplifier is amplified, the flame is induced to exist, and the small power burner adopts the detection mode more, and is economical and practical.

Q: How many kinds of industrial electric furnaces are there?: Electric furnace is divided into four categories: resistance furnace, induction furnace, arc furnace and special electric furnace according to the different ways of electric heating.

Q: What are the advantages of a vacuum furnace?: The accuracy of furnace temperature measurement and monitoring is obviously improved. The indicating temperature of the thermocouple and the temperature of the furnace reach 1.5 C. But there is a large temperature difference in a large number of workpieces in different parts of the furnace. If the forced circulation of the rarefied gas is adopted, the temperature range of the temperature range of + 5 DEG C can still be controlled.

Q: How to use industrial furnace equipment?: When the furnace is used, the lifting mechanism of the furnace door must be in good condition, and the wire breakage of the steel wire is not allowed to exceed the designated value. The weight should be properly allocated, and the drive department shall be provided with a protective cover.

Q: Brief introduction to repair of industrial furnace: Compared with other equipment, industrial furnace repair has many characteristics: more repair times, more maintenance costs, more non-standard equipment and unsafe factors.

Q: What is the difference in structure between industrial furnace and boiler?: At the same time, the working environment is relatively poor, the structure should be sturdy and durable, the transfer mechanism (generally) to stable and durable low failure rate, the insulation layer must be thick enough and the economy, the steel structure housing materials used to be enough.
