slag pot

The slag pot is an important equipment for steel-making in the metallurgical industry. It is a container used to contain the high-temperature slag produced in the steel smelting process. It has a bowl-shaped container with hoisting trunnions on both sides.

Advantages of AGICO Slag Pot

1.2000+ times of usage    
Unlike slag pot from other brand which has the service life of 400-600 times of usage, AGICO Cement's slag pot can be used for more than 2000+ times. Service life increased by 20%.

2. Simulation&modeling before producing    
Before pouring, the casting process is digitally simulated by CAE software to analyse the process and predict quality of the molding process of the product, which will further optimize the process of slag pot casting. The water glass sand molding process is applied with complete metallurgical auxiliaries to prevent the occurrence of hot cracks in castings and control its overall size. Meanwhile, pit modeling method applied in the process will not affected by the season and enjoy high production efficiency.

3. Pouring&heat treatment

The raw and auxiliary materials that pass the inspection are put into the electric arc furnace for smelting in proportion. The molten iron sample is sampled for spectral analysis. After it is  qualified, it is poured in accordance with the principle of "low temperature and fast pouring", and the pouring time and temperature are recorded. In view of the problem that the carbon content difference between the two materials of trunnion alloy steel and tank carbon steel is relatively large, AGICO Cement has customized a complete set of processes to strictly control the welding problems in the production process.

4.Grinding&shot blasting

Operations such as cutting, pouring, and flashing are carried out after the above processes. AGICO Cement has a professional grinding and finishing team and large-scale shot blasting equipment, which can effectively improve the appearance quality of the slag pot and make its surface quality meets customer’s requirements. The internal quality of the slag pot is strictly prohibited from leaving any defective products.

5.Slag pot from reliable manufacturer       
AGICO Cement has strong capabilities of casting, processing and assembly which can provide customers with 150 tons / piece of large carbon steel castings, manganese steel castings, high-alloy steel castings and other cast steel parts. AGICO Cement's high-quality slag pot are exported to the United States, Germany, France, Italy, India, Indonesia, South Korea, Turkey and other more than 60 countries and regions.

Common problem of slag pot

In production practice, the use of slag pots in ferroalloy smelting mainly has the following problems:      
1. Due to the design of the overflow port of the slag pot, the center of gravity of the slag pot is offset. The slag pot is inclined during the lifting process and the slag liquid is easy to overflow which has a great hidden danger.      
2. The overall structure of the slag tank is unreasonable. After being subjected to thermal stress, cracks are easily generated, and cracks will cause piercing.      
3. It is designed to use one lined ladle and three slag pots. Sometimes too much molten iron will overflow from the ladle to the slag tank, causing the temperature at the bottom of the slag tank to rise sharply, which will cause damage to the slag pot.

Improvement measures of slag pot producing by AGICO CEMENT

1. Thicken the wall thickness inside the slag pot so that the center of gravity can be balanced after the slag pot is lifted.      
2. The improvement part is to cancel the upper reinforcing edge of the slag pot, the bottom, middle and upper part of the slag pot are thin and uniform. The bottom reinforcement edge is reserved for expansion joints, and the bottom is added with strong ribs.      
3. Change the structure of the tapping car from the original combination of one lined hot metal ladle and three slag pots to two lined hot metal ladles and two slag pots, which can effectively prevent the molten iron from flowing into the slag pot (which will cause local high temperature damage to the slag pot).
