The tundish is a container located between the ladle and the crystallizer in the continuous casting process. It is responsible for many tasks such as receiving and storing molten steel, smoothing the flow, purifying the molten steel, and diverting the molten steel into the crystallizer. As the last refractory container before the molten steel solidifies,

Refractory castable is composed of refractory aggregate and matrix powder, adding a certain amount of binding agent and additives together. At the time of construction, water is added for mixing to make it have good fluidity, and further after molding and maintenance to make it coagulate and harden. Because of its high construction efficiency, simple

In the process of refractory brick masonry, usually use refractory mud for masonry, and can not choose refractory cement for masonry, although both belong to the refractory material, but in the actual application of the process there is a big difference. Refractory mud, also known as fire clay or jointing material, is a jointing material

The design of the electric furnace and the configuration of the refractory material for the furnace lining affect the operating life of the converter. The following is a description of the design of the furnace roof, cylinder and hearth as well as the configuration of the refractory material for the lining of the furnace. 1.Furnace

The heating temperature of the electric furnace depends on the material and power of the heating element. Generally speaking, the heating temperature of the electric furnace can reach more than 1000℃, and if the high temperature alloy material is used to make the heating element, it can even reach a high temperature of more than

Classification of refractory materials 1.Refractory materials can be divided into 8 categories according to the chemical mineral composition: siliceous materials. Aluminum silicate material. Magnesium material. Dolomitic materials. Chromium material. Carbon materials. Zirconium Special refractories. 2.Refractory materials can be divided into 3 categories according to chemical properties: acid refractory materials. Neutral refractories Alkaline refractories. 3.Refractory materials

Electric arc furnace is a kind of electric furnace that utilizes electric arc energy to smelt metal. Industrial application of electric arc furnace can be divided into three categories: the first category is direct heating type, the arc occurs in the special electrode rod and be melted between the charge, the charge is directly subjected

With the development of new dry-process cement production technology, the corresponding refractory materials have also made great progress. In addition to the conventional refractory bricks have a breakthrough, the performance of refractory castables is also more and more perfect, and widely used in the kiln in the amorphous parts. As we all know, refractory castable

The traditional medium frequency furnace lining material has three kinds, one is acidic furnace lining, by quartz sand dry pounding molding, binder for borax or boric acid; another is magnesium sand dry pounding molding, binder is also borax or boric acid. The last one is neutral furnace lining, pounding molding by high alumina bauxite clinker.
