Yufeng Refractory offers wide range of high quality refractory products to meet specific demands of clients in each step of the steel production and process . we always work together with our clients and know what they want and provide top quality refractory lining material .
Converter The selection of refractory products for converter linings requires an intensive study of the operating conditions at the plants of our customers. Hereby, the installation conditions, the converter's condition, and the time frame for installation must also be taken into account. Depending on the lining zone, the causes of wear can be very different. However, the main causes of wear are thermal, chemical and/or mechanical.
Coking Oven It is usually made of refractory bricks and refractory blocks for coal to produce coke. A kiln that refines coke with coal. It is the main thermal equipment of coking. Thecoke oven body consists of the top of the furnace, the combustion chamber and the carbonization chamber, the chute area, the regenerator, etc., and is connected bythe flue and the chimney.
Blast Furnace The blast furnace is made of steel plate as the furnace shell, and the lining of the refractory brick is built in the shell. The blast furnace body is divided into five parts: the throat, the furnace body, the furnace waist, the belly, and the hearth.Longer running times and shorter down-times for new linings or repairs mean that specific solutions are required increasingly often for the refractory lining of blast furnace stacks and runner systems. Consequently, a balanced ratio of SiC to carbon is just as important in a successful material as selecting the right type of bond or the type of lining.Therefore, Yufengrec provides concepts that are matched to the requirements of every runner section and take the latest developments into account.
Pig Iron Transportation Metallurgical processing steps are partially carried out in pig iron vessel devices such as torpedo ladles and charging ladles, although the actual task of these devices is the transport from blast furnace to steel plant and for filling converters. For all standard lining concepts, YUFENG Steel supplies bauxite, calcined or carbon-bonded andalusite and – at a presently increased level – high-grade carbon-bonded bauxite with SiC additive. And of course, refractory castables for pouring areas and repair are also included in the product range.
Electric Arh Furnace Smelts ore and metal at a high temperature generated by an electrode arc. When the gas discharge forms an arc, the energy is concentrated, and the arc temperature is above 3000 °C. For smelting metals, the electric arc furnace has greater flexibility than other steelmaking furnaces, and can effectively remove impurities such as sulfur and phosphorus. The furnace temperature is easy to control, and the equipment has a small footprint, which is suitable for the melting of high-quality alloy steel.Many well known steel producers and foundries use YUFENGREC products when building their electric arc furnaces. In many years of practical application, the high-grade and super-grade high-purity fused magnesia products have proved their worth and have helped to extend furnace service life and reduce maintenance. The result is a considerable reduction in costs. Top-quality tapping systems and high-performance refractory adhesives complete the product range.
