Flame cleaning machine dust removal 1.1 The flue gas generated by the flame cleaner should be controlled,and the dust removal design should consider the characteristics of dust concentration,flue gas moisture content,iron trioxide content in dust,dust particle size etc. 1.2 A detachable movable fume hood is set at the passing part of the blank mold of…
At about 12:00 on September 8, 2020, a red continuous casting slab with a mission started from No. 7 caster. Originally, it needs to be hoisted to the storage area, waiting for the billet to be transported to the heating furnace by car. This time, it is directly transported to the straight rolling rod track.…
The ladle is a special container that load high-temperature molten steel. It is an important equipment linking the converter and continuous casting production. It is a major risk in steelmaking production that needs to be strictly controlled. Ladle operation is very demanding on safety. The ladle workshop of the steelmaking plant is not only responsible…
The “Integration of Steelmaking, Continuous Casting and Rolling” plan integration and scheduling technology, automatic control technology and comprehensive shape control technology have been developed into key common technologies in the production process of hot-rolled wide strip steel, which are important for energy saving, product quality control, and enterprise economy. Increased efficiency is decisive. The…
Magnesia-carbon brick is a high-quality refractory material. Because this kind of carbon-containing refractory product has the advantages of high refractoriness, good slag corrosion resistance, strong thermal shock resistance and low high temperature creep, it is widely used in electric furnaces, converters and ladles. The service life has been greatly improved. At the same time,…
The production practice of continuous casting has proved that low molten steel superheat can refine the grains of continuous casting slab and reduce center segregation; constant temperature and low superheat casting can reduce and maintain the heat flux density, thereby preventing breakout and corner cracks of the slab; only available The system of tundish molten…
Argon gas adjustment during continuous casting Argon blowing, argon blowing, the upper (water) port is generally not as big as a stopper; The pulling speed changes, the large and small change to blow argon, the goldfish spit out and see “ghost fire”, and the liquid level data is set high. Better argon blowing state of…
There are three four-machine four-strand continuous casters in the second steelmaking plant of Anyang Iron and Steel Co., Ltd., two arc-shaped radii of 5250mm, and one arc-shaped In the production process, the quality defects of the cast slab fall off sometimes appear. As a unique shape of billet continuous casting shape defect is a quality…
The main task of the continuous casting operation area is making molten steel into qualified slabs. The indispensable thing is cooling water. Whether the cooling water can be used correctly is related to the continuous casting machine breakout accident and the quality control of the slab. The engineer operated the following points： In order to…
Steel position disassembly cylinder manipulator Two ABB manipulators, model IRBA67, are installed on the ladle steel side.The system mainly includes: identifying and positioning equipment;Disassembly and installation of slide oil cylinder jig;Medium pipe plugging fixture;Air control box and its pipelines;Robot pipeline package, etc.These two manipulators are mainly used to realize the functions of oil cylinder, energy…
