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: Micro nano heat insulation board.The thermal conductivity of micro nano heat insulation board is very low, only a fraction of the traditional thermal insulation material, and the insulation effect is very efficient.

Q: Heat treatment equipment (industrial furnace), which products generally contain what kind of, which industries need to use heat treatment industrial furnace equipment.: The main equipments of heat treatment are classified into two major categories: main equipment and auxiliary equipment. The main equipment includes heat treatment furnace, heating device, surface modification, surface oxidation device, surface mechanical enhancement device, cooling equipment, cold processing equipment, process parameter detection and control instrument; auxiliary equipment includes cleaning cleaning equipment, furnace atmosphere heating medium permeability meter preparation equipment, cooling device, quenching medium heavy transport machinery, quality testing equipment, power transmission line and auxiliary equipment, fire safety equipment, dust and other production fixture.

Q: What are the combustion equipments used in industrial boilers?: The boiler is an energy conversion equipment. The energy input to the boiler has the chemical energy and the electric energy in the fuel. The boiler outputs steam with certain heat energy and high temperature water.

Q: What is industrial furnace masonry?: Before masonry construction, the pre process and parts that may affect the quality of masonry work shall be re tested,masonry construction shall be carried out according to the datum central line and the datum elevation.

Q: What's the role of anchor bricks in industrial furnaces?: These layers need to be joined and anchored. Anchor brick is this role. The heat insulation layer at the horizontal section of the flue is mostly a narrow cavity.

Q: Why does the burner of industrial furnace burn occasionally?: The general process for burner ignition, blowing furnace, electric spark ignition, solenoid valve, open the gas in case of delayed spark ignition, detection device detects the flame, the controller accepts signal so that the solenoid valve open, gas continuous normal combustion. However, if the ignition fails or the burner fires, the detector cannot detect the flame, which causes the solenoid valve to close and the burner flameout.

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 is the difference between industrial furnace masonry and ordinary masonry?: Furnace industry is not generally Mason walls, needs to have a professional operation and rich construction experience, high level of industrial furnace is difficult to get.

Q: How to use industrial furnace equipment?: If it is water cooling furnace door, but also to ensure the smooth flow of pipes, winter pipes are not frozen. When the boiler is in a limited position, the interlocking device for cutting off the power supply shall be provided when the furnace is in and out, and the number of broken wires in the pitch of the steel wire shall not exceed 10%, and the counterweight of the furnace door shall be reliably hung.

Q: What is an industrial furnace pit?: Later, a chamber kiln with a semi closed or fully enclosed kiln made of refractory bricks can be used as fuel for coal, gas or oil, and electricity can be used as heat source. The workpiece will be heated in the kiln hearth.
