  Left-right swing AOD furnace baker, mainly composed of a pivoting support mechanism, a blower, a ladle cover, a combustor support and a control system, is suitable for the offline baking of double-station AOD furnace.

   AOD furnace refining technology, an important way to produce high-quality stainless steel is widely applied through many years’ development. The AOD furnace baking is extremely important to reach ideal refining effect. AOD furnace baker developed through years of repetition tests is 2-4m in flame length, flame can directly reach the hearth, with special-designed combustor featured by full combustion, no fume, low emission and long service life through special design. Since the first set of 35T vertical offline baker was put into use in Baosteel in 2000, the company has offered hundred of AOD furnace bakers for stainless steel enterprises at home, with the design tonnage ranging from 3T to 90T.    AOD furnace baker is divided into vertical type and horizontal type, composed of a baking support, a lengthening flame combustor, a fuel supply system, and a combustion air supply system. The combustor, a flame combustion type, is characterized by long flame and large fire disc in combustion, and the flame can be regulated at any time. The vertical baking is further divided into a left-right swing type and a winch elevation start and stop type, wherein the combustor is fixed on a cantilever beam in the winch elevation start and stop type baker, and a cover is further arranged on the tank port for preventing heat loss, so as to keep heat within the tank as far as possible, simultaneously protect the combustor from being burnt out, and prolong service life. Left-right swing AOD furnace baker enables the cantilever beam (air pipe and fuel pipe) on the support to move with the cover through the swing of the pivoting support, thereby realizing the baking for AOD furnace in different stations.     

Steel (molten iron) ladle baker

 

Introduction

  Steel (molten iron) ladle baker is a smelting procedure widely used in metallurgy enterprises at home. Adopting ladle cover sealing or half sealing mode baking, it is provided with laminar flow back-mixed type low-pressure burners, and utilizes gases or oil as fuel, high-temperature flame rushes to the bottom of the ladle after ignition, and then high-temperature fume returns along the bottom of the ladle, and forms turbulence with following high-temperature fume, so as to ensure temperature inside ladle to be uniform without hardening the furnace lining crack owing to partial high temperature.

  Steel (molten iron) ladle baker is necessary equipment in the steel industry for heating and baking steel (molten iron) ladle used in transfer and baking newly-bricked refractory steel (molten iron) ladles to dry and dehydrate in the steelmaking process.

Features:

1. It has wide application to combustion mediums, including various gas fuels (blast-furnace gas, generator gas, mixed gas, converter gas, coke oven gas and natural gas), light diesel oil, and used for oil-gas baking.

2. The frame is designed in the form of tower, with reasonable stress distribution, good folding and bending resistance, firmness and stability, reducing the requirement on foundation.

3. It has reliable performance and long service life, and combustor burners are stable in combustion performance as being made from stainless steel, so the replacement rate of accessories is reduced.

4. It has low baking cost as adopting blast-furnace gas, converter gas and other combustion mediums which are byproducts of steel works. At the same time, the heat efficiency of the combustor is fully optimized, so as to reduce loss of fuel, and be more energy-saving and eco-friendly.

5. It can meet rapid temperature rising, and it only needs about 25 minutes to raise the temperature of the molten steel ladle to over 900 °C from 500-700 °C.   

6. Molten steel ladle has small temperature difference (≤50 °C), and the combustor is provided with laminar flow high-speed burners with high gas outlet speed, so high-temperature gas flow rushes to the bottom of the ladle powerfully to enhance the convection heat transfer to the ladle lining.

7. It realizes the baking automation (wherein customers can select accessories by themselves), simultaneously meets the low-speed drying baking for new-bricked ladles and rapid temperature rising before tapping.

8. It is stable to operate, safe and reliable, as hoisting winch is provided with a pulley block, a deceleration and load reducing mechanism, and further mechanical and electrical limits.

9. Baker cover is convenient to be opened to a max angle of 85°, convenient for crown block to allocate and transport.

10. Baking operation fields have less harmful gases, safe and eco-friendly.
