Automation's whole-process intelligent robot temperature measurement and sampling system

In recent years, intelligent manufacturing has gradually entered the public eye and has become a breakthrough for the steel industry to implement innovation-driven development. Temperature measurement, oxygen determination, and slag breaking are important links in the iron and steel metallurgical process. At present, most of them are done manually. The labor intensity is high, the working environment is harsh, the temperature measurement accuracy is not high, and the sampling success rate is low. The "warm sampling robot" is of great significance to promote the intelligentization of China's steel industry.

WISDRI Automation takes the lead in adopting an integrated intelligent temperature measurement and sampling program that closely cooperates with robots and automatic feeding systems, which completely replaces manual labor. While improving the operating safety factor and effectively avoiding safety accidents, it ensures the accuracy of temperature measurement and sampling data. The real-time nature has improved the efficiency of on-site operations and realized unmanned and intelligent operation of temperature measurement and sampling, which has taken an important step towards the realization of fully intelligent production in the steel industry.

Tundish uses robots to improve operations and safety

During manual operation of continuous casting tundish, temperature measurement, sampling, addition of protective slag and shroud loading and unloading work, the operator will be exposed to high temperature and dust environment, labor intensity, accidental reaction splashing or ladle formation in the tundish There is a certain danger when the shell falls. Working in this environment, these indispensable operational tasks must be completed to ensure the stability of the continuous casting process and the quality of the slab. By using two robots to realize automatic tundish operations, safety and operating efficiency can be greatly improved, and process reliability can be improved. This article introduces the layout, composition, characteristics and operation of the tundish robot project in detail.

Electric furnace refractory brick configuration plan

According to the needs of comprehensive utilization of vanadium-titanium magnetite, Panzhihua Iron and Steel began to study the process of direct reduction of vanadium-titanium magnetite in the 1980s. Based on previous studies, this process boldly proposes a new process route of direct reduction melting and deep reduction-vanadium extraction from hot metal-high titanium slag based on the characteristics of vanadium-titanium magnetite, which not only realizes the realization of vanadium-titanium magnetite smelting hot metal It also creatively realizes the one-time separation and comprehensive recycling of iron, vanadium and titanium. However, since the new process smelting electric furnace has been put into production, there have been many production and operation problems. The excessively high open arc temperature caused serious deformation of the furnace cover, and the mismatch of the furnace lining and the acid titanium slag caused the rapid corrosion of the furnace lining, which had the greatest impact on production and test operation.

Analysis of problems existing in the use of ladle and improvement measures

•  Problem analysis

1.1 The bottom of the ladle has poor corrosion resistance

The corrosion of refractory materials is divided into physical erosion and chemical erosion. Physical erosion refers to the erosion of refractory materials by impact and other mechanical effects; while chemical erosion refers to the resistance of refractory materials to changes in temperature and stress fields under high temperature load. Erosion of wood. The bottom of the ladle is mainly physical erosion. During the use of the ladle, the bottom working layer of the ladle has poor corrosion resistance and impact resistance. Under the impact and erosion of high temperature molten steel, a large area of refractory material will fall off, and the delamination thickness is 100 mm ~ 150 mm. The layers are mostly concentrated on the impact position of the molten steel (as shown in the figure below), which brings great hidden dangers to the safe use of the ladle.

Causes and control measures of four major surface defects of billet

• reconnect

1. 1 Reasons

a. Pouring is interrupted due to various operating failures, and reconnection defects are easily caused on the surface of the cast slab after re-pouring.

b. Slow drawing speed results in too deep vibration marks on the surface of the cast slab, forming a reconnection. 

Influence of Electromagnetic Stirring at the Bottom of the Furnace on the Process of Smelting Stainless Steel in Electric Furnace

 Abstract: The electromagnetic stirrer (ArcSave⑧) installed under the bottom of the electric furnace can effectively mix the molten steel in the entire molten pool, thereby accelerating the homogenization of the molten steel temperature and chemical composition during the melting process. The influence of electromagnetic stirring on the smelting process of stainless steel in a 90t electric furnace at Outokumpu Stainless Steel Plant in Sweden was studied. The thermal test results show that ArcSave can accelerate the melting of scrap steel and ferrochrome alloys, and accurately control the tapping volume;

What is a converter bomb fast analyzer

 

The converter bomb-dropping fast analyzer is suitable for 40-150 tons of converter without sub-lance. With a small investment, the converter steelmaking process does not turn out of the furnace and can detect temperature, oxygen, and carbon components with one button, speed up the steelmaking rhythm, increase production, reduce smelting costs, and achieve clean steelmaking and improve the quality of molten steel.

Magnesia-carbon brick, Ladle, slag line brick, Uneven erosion

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.
