The converter in our steelmaking plant is 180T, and the bottom drop of the converter is too large. Ask how to make the bottom of converter rise! ! !

1, bottom filling method can be used, which is simple and effective.

2. Adjust the slag discharging system to make the slag sticky.

3. Slag properly, first add scrap steel, shake the furnace to the end, and press the slag to the end with scrap steel.

4. Lower the gun position and cooperate with secondary slagging.

5, keep the surface size, ensure the surface size without material loss.

1. Steelmaking plant is a kind of heavy industry, secondary industry, manufacturing industry, capital-intensive industry, fixed assets and factory. The raw materials of steel mills are iron ore, coal and carbon, which are supplied by the mining industry. Because steel mills are strategic material producers, most countries are state-owned enterprises. The main task of steelmaking plant is to desulfurize, dephosphorize, decarburize and deoxidize molten iron, and then cast molten steel into billet.

2. Production scale and product overview: The production scale of steel mills refers to the annual raw steel output, that is, the annual production of qualified ingots or qualified continuous casting billets or the sum of both. But for steel mills, it is also necessary to distinguish between their "capacity" and "actual (or planned) output". When the equipment runs normally and is not affected by external unexpected factors, it is actually the same. However, due to market factors or other reasons, the operating rate of some factories may be insufficient, so the actual output will be lower than the equipment capacity. The output of steel mills is determined by the steel production demand of enterprises. The product plan of the enterprise determines the type of processing technology and equipment, and then determines the quality, cross-sectional shape and size of billet or ingot provided by the steel mill. According to the requirements of processing technology, the supply of billet (or ingot) is calculated according to different steel grades (tons). This is usually called the product outline of steel works. When designing a steel plant, we should first formulate a product outline (or design a product plan), and list in detail the steel grades to be smelted and several representative steel grades of each steel grade; The output of each steel grade and its proportion to the total output; Section shape, size and fixed length of continuous casting billet (or ingot) cast by various steel grades. In order to understand the production process of each steel grade, it is also necessary to explain which subsequent processing procedure all kinds of billets (or ingots) are sent to, so as to clearly describe the product variety, output, specific gravity and destination of the steelmaking plant.
