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 materials actually have different applications in various industries! However, their most common applications are in the following five areas. (I) Steelmaking system The steelmaking system includes equipment such as converters, electric furnaces, off-site refining furnaces, ladles and tundishes. In electric furnaces, dry vibrating materials, prefabricated or cast-in-place furnace covers or furnace cover triangles and
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,

The strength of granular materials in castables is generally higher than the strength of the hardening body of the bonding agent and the bonding strength between the granules, so the room temperature strength of castables actually depends on the strength of the hardening body of the bonding agent. Changes in strength at medium and high

The development of induction furnace and the progress of refractory material technology is closely related to the design of large-scale industrial crucible induction furnace is often first from the choice of refractory materials and furnace lining simulation test. Trench induction furnace capacity increase, the expansion of the scope of application (from non-ferrous metal melting to
Medium frequency furnace furnace lining materials, also known as medium frequency furnace refractory materials, medium frequency furnace dry vibration material, medium frequency furnace knotted material, medium frequency furnace pounding material, divided into acidic, neutral, alkaline furnace lining materials, acidic furnace lining materials are based on high purity quartz, fused quartz as the main raw material,
