Magnesia carbon bricks remain the most widely used refractory material in steelmaking today due to their high cost-effectiveness. While they offer significant advantages in corrosion resistance and spalling resistance, they also suffer from poor thermal insulation and the tendency to carburize ultra-low carbon molten steel. With the increasing specialization and segmentation of steel grades, higher […]

Changes in the refractory market The refractory market is experiencing a new transformation, with high-alumina bricks attracting significant attention. As energy conservation and environmental protection become increasingly popular, refractory product features are constantly being upgraded to meet new market demands. High-alumina bricks, with their exceptional energy-saving properties, are becoming a new favorite in the market.

With the increasing requirements for clean steel in various industries and the development of continuous casting technology, the metallurgical function of the tundish between the ladle and the crystallizer has received more and more attention. Tundish metallurgy can prevent secondary oxidation of molten steel, improve the flow state of molten steel, prevent slag rolling and

Selection of ladle According to the smelting conditions, there are two types of ladle: standard type and short and fat type. 1、Heat transfer calculation Establish the mathematical model of ladle, according to the structural characteristics of the ladle, the heat transfer calculation of the ladle to do the following assumptions. 1) The wall of ladle

Refractory castables, as an indispensable refractory material, have strength characteristics that are directly related to their quality and performance. In many industrial fields, such as metallurgy, cement production, glass manufacturing and chemical industry, castables play a pivotal role. Therefore, the research and development of high-performance castables is particularly important. Aluminum-magnesium castables are particularly worth mentioning,

Requirements for refractory mortar in refractory brick masonry (1) The working conditions of the mud in the joints of refractory masonry bricks are exactly the same as those of refractory bricks. Therefore, the main technical indicators of the two, refractoriness and chemical composition, should also be the same or compatible. (2) The type and brand

Ladle, also known as steel barrel, steel tank, big bag, etc., is a container for storing, transporting and processing molten steel. It is an important equipment for refining tasks. The ladle has two main functions: the first is to receive molten steel; the second is to perform refining outside the furnace. With the diversification of

Steelmaking refractories include the lining of liquid iron, liquid molten steel containers and related furnace protection and heat preservation materials, which can be specifically divided into ladle lining, converter lining, ladle lining and intermediate ladle lining and related supporting steel outlet, sliding water outlet, continuous casting of the three major pieces of fixed refractory materials,
