Refractory Materials

        The supply of refractory materials is a key issue for the world steel industry. Yilong Refractory manages refractories that widely used in steelmaking, metallurgy, glass making, cement making, ceramic making, etc.

Iron ore and coking coal are used mainly in the blast furnace process of ironmaking. For this process, coking coal is turned into coke, an almost pure form of carbon, which is used as the main fuel and reductant in a blast furnace.

Typically, it takes 1.5 tonnes of iron ore and around 450kg of coke to produce a tonne of pig iron, the raw iron that comes out of a blast furnace. Some of the coke can be replaced by injecting pulverised coal into the blast furnace.

Scrap iron is mainly used in electric arc furnace steelmaking. As well as scrap arising from the making and using of steel, obsolete scrap from demolished structures and end-of life vehicles and machinery is recycled to make new steel. Around 500 million tonnes of scrap are melted each year.

Refractory is a common material on the earth’s surface. Most refractories are located in China, carried to dedicated ports by rail, and then shipped to steel plants in Asia, Africa, South America and Europe.

Sea freight is an element of major concern for steelmakers today, as the high demand for raw materials is causing backlogs at ports.

Deoxidizer,Refractory Mateiral

Deoxidizer

Oxygen absorber is the materials used to reduce the content of Oxygen and other gases in molten steel. Our company has developed the compound deoxidizeaccording to the needs of steel smelting application to various forms of deoxidization process. The product is good at deoxidization, and also can reduce harmful gases in molten steel, improve liquidity, reduce impurity to pure the molten steel, improve the yield of alloy steel, and reduce the dosage of alloy that is reduce costs. At the same time, it can replace parts of ferrosilicon and calcium silicon, reduce or eliminate wire feeding process, simplify steelmaking operation, improve the quality of steel, and the economic benefit is remarkable.

Tundish Slag Dam

Tundish Slag Dam

The tundish slag dam is the auxiliary product of the continuous casting tundish, which is beneficial to separate slag, prevent slag into the crystallizer and improve quality of liquid steel. This product features in erosion resistance, good high-temperature property, high heat stability and long service life.

The refractory material refining quality steel casted by Henan province has reached top level of China

Currently, tourisms learn from Technology Department of Henan that the project of refractory material refining quality steel undertook by Luoyang Refractory Research Institute has passed acceptance check.. By carrying such an project, they have solved the key technology problem of short life span of LF+VD refining ladle refractory material that used in casting steel, and the life span increases from 85 heats to 135 heats. The person in charge of Technology Department of Henan has said that such a refractory material project has obtained two patents, formed productive capacity of 15 thousand ton per year and increased output value is 133 million. The appearing temperature of refractory material used by refining quality steel is lower 60℃～80℃ than ordinary ladle, which obviously reduces the power consumption of per ton steel, and very important for saving graphite and reduce heat loss of ladle. Now, with industrial structural adjustment of steel industry and increase of high quality special steel, which project carrying by Technology Department of Henan will promote such a proceeding in a big degree. If the factory in China can turn 5 million ordinary steel making to refining steel making per year, which will bring 12.5 billion income for steel industry, and the social benefits is obviously.
