What are the refractories used in furnaces? Heat treatment temperature of the reheating furnace is not high, generally its service temperature is lower than 1300℃. For reheating furnace lining, usually we use Al-Si refractory materials which contains alumina 36-75%. The reheating furnace is used for bloom, continuous casting, small steel ingot to meet the temperature …
Castable lining construction 1. Refractory castable construction 2. Castable stir Mixing time should be no less than 5 minutes. Operation to use a forced mixer, stirring should first dry mixing, then add 80% solvent stirring, and then depending on the degree of wet and dry construction and specific parts of the request, and then slowly …

20th Century 50–70 years, China’s steel plants mainly used aluminosilicate refractory materials, including clay, alumina brick and so on. Since the 1980s, China has successively developed the aluminum-magnesium carbon, coal quality calcium and magnesium and other several series of new steel package refractories. Wherein the aluminum-magnesium carbon refractory materials are of varieties, all specifications, is …

Ladle shroud, also named as long nozzle, as a refractory product it is used as a connection nozzle between Ladle and Tundish. In order to keep the molten liquid from being oxidized and splattered when it flows from ladle to tundish, a shroud is needed to be installed underneath the ladle. One side is connected …
Monoblock stopper is formed by static pressing. The shape and size depend on the capacity of tundish, the height of steel surface, horn shape of tundish nozzle and aperture size. Monoblock stopper head is monoblock stopper hollow with argon blowing hole and air plug. The key point is fixing method. One type is fixed by …

As a refractory material for the lining of the refining furnace, the aluminum-magnesium carbon brick fully exerts the strong slag corrosion resistance of the magnesia, the low expansion of carbon and the high thermal conductivity, and makes up for the defect of the spalling resistance of the magnesia. The excellent performance of aluminum-magnesium carbon brick …
Refractory bricks thermal conductivity The thermal conductivity of fire bricks is represented by the thermal conductivity that has the ability to transfer heat. Thermal conductivity represents the amount of heat per in unit area, unit time and unit temperature gradient in the energy transfer process. At 1000 ℃The thermal conductivity of various refractory bricks rate …

The process flow of magnesia carbon brick production 1.Broken to pieces 2.Ingredients (weighing) 3.Preparation of mud (mixing, kneading) 4.Forming 5.Heat treatment The details of manufacturing magnesia carbon bricks are as …
Making high alumina brick as following: The most common way to manufacture high alumina brick is through the firing of bauxite, which naturally contains a blend of both aluminum oxide and something called “kaolinitic clay”, which is a clay composed of layered silica. Once this material is fired it creates a composition of alumina and mullite, …
Tundish nozzle plays a very important role in ladle steel making. This article introduces how to make tundish nozzle and the types of tundish nozzle clogging. On the other hand, it is also possible to understand the types and differences of refractory nozzles.Tundish nozzle manufacturing method, relates to a production method of a molten steel …
