In recent years, some steel casting companies in our country have adopted spinel-type furnace lining materials. Among them, some manufacturers purchase materials pre-prepared by foreign manufacturers. Although the use effect is very good, the production cost has increased a lot, and its characteristics are not good. Very understanding. This article mainly wants to introduce some …
During our visits to many steel companies around the world, we found that some of them focus too much on the service life of ladle slide gate plate and lower nozzle, some even ask for more than 10 heats, here are some of our opinions on this condition: 1.Longer service life slide gate plate and …

In the ladle, due to the complex physical and chemical environment at the slag line, the furnace lining is the most vulnerable to damage. The chemical attack of steel slag on magnesia-carbon bricks is mainly through the dissolution of magnesia and the oxidation of graphite in the fire brick body. Under the combined action of …
With the reform and improvement of continuous casting technology and functional refractories, the most commonly used in our country is the zirconium sizing nozzle. According to the content of zirconia in the sizing nozzle, the zirconium sizing nozzle can be divided into ordinary type sizing water and zirconia type sizing water are two categories, ordinary …
Ferroalloy electric furnace furnaces, especially cold stamped paste villages, when the knotting quality does not meet the required requirements, and the oven lining time and heating rate are not closely controlled during baking, the baking quality of the furnace village will not be achieved. To normal production requirements. According to the reasons for the damage …

Sliding plate is the core component of ladle sliding spout, which is the component that directly controls steel pouring and determines the function of sliding spout. If the sliding plate leaks steel in the process of steel pouring, it will cause the continuous casting to break pouring, or cause the vicious accident of burning out …

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 …

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 …
