The principle of slag stopping ball：its density is between the steel's and slag's density(usually 3.8g/cm3～4g/cm3). Before the tapping ends, it is released by the mechanical arm and it sinks to the taphole mouth，therefore blocking
the slag. There are simple structure and low cost for slag stopping ball, which can meet all technological requirments.
The advantage of the slag-blocking ball
The use effect of the slag retaining ball can be evaluated by observing the shape of the steel nozzle. When the slag is good, the steel water should be in a circular flow.In addition, it can be judged by the color of the lower slag.The action of the grooves in the trap is to prevent the slag from flowing out of the steel.The effect of the slag retaining ball can be evaluated by the thickness of the slag layer in the ladle, the energy saving block ball and the alloy yield.The slag layer thickness is small, the slag ball is blocked, the alloy is high, the slag ball is used in steelmaking, and the slag is good.If you have any questions, or if you need anything, you can call us at any time.We will do everything we can to help you.
For many years, high quality slag ball, domestic and international numerous metallurgical workers to research and development will be very low amount of steel slag into the technology and method, in addition to the less slag, slag smelting process, mainly developed various slag technology and products, to minimize the converter steel late eddy current out of the amount of steel slag.Such as slag, slag stopper, skateboard, pneumatic slag, the tapping hole blow air disturbance vortex method, both outflow slag, tundish, the steel plate cutting slag, slag cap, slag cover, vacuum residue, siphon tapping method, etc.
Steel: effectively prevents the water from returning to the phosphorus and returning the sulfur.Take effective when the converter steel slag operation, is an important way to improve the quality of molten steel, can not only reduce molten steel returning the phosphorus, sulfur, improve the alloy yield, reducing inclusions in molten steel, improving steel cleanliness, but also create conditions for further refining.Reduce deoxidizer and alloy consumption.Take effective when the converter steel slag operation, not only can reduce deoxidizing agent and alloy consumption, reduce the ladle slag viscosity, prolong the service life of the ladle, it can improve the service life of refractory material of converter tapping hole area, reduce the production cost of steel products.
The converter slag ball is a spherical structure with grooves, which can effectively reduce slag in the ladle and increase the metal yield.And the rate of the investment is higher than that of the same type of products.The scum ball is a conical plug with grooves made of mechanical equipment, which can strictly control the amount of slag in the process of steel converter.The series products have the characteristics of high refractoriness, high strength and high thermal shock stability.
It is obvious that the reasonable density is 4.2 ~ 4.59/ cm3.The slag ball is a spherical structure, and its center is composed of cast iron blocks, raw iron chips or small scrap steel.High alumina refractory concrete or refractory bricks can be used as high bauxite refractory concrete or magnesium-quality refractory mortar.The diameter of the deflector ball should be slightly greater than the diameter of the steel hole to play the slag.The slag ball is usually put in between 2/3 and 3/4 steel, and the slag ratio is high.The slag is too sticky to affect the slag blocking effect.The slag can be put into the slag ball to improve the slag ratio.
Our company has hired super experts and social activists from the fields of scientific research, production, economy, business community and education, joining hands with universities and research institutions to commit ourselves to new metallurgical material and new technology processing, production, research and development and utilization. We have two large metallurgical material production bases, including hydrometallurgy, two key laboratories, a metallurgical material testing center and dozens of senior researchers. We focus on metallurgical material research, production and operation. On one hand, we concentrate on the production, processing and sale of ferroalloy, steel, pig iron, trace element and other metallurgical material and our refractory products and other products are exported to more than 10 countries and regions. On the other hand, we undertake such businesses as special research, market research and feasibility study and development. Our company recruits foreign investment for consultation, training, technology transfer and technology renovation.
We highly welcome domestic and overseas economic entities to join us. We'd like to seek for win-win common development to make a contribution to the revitalization of the national economy.
