Rotary ventilating brick, intermediate frequency furnace ventilating brick

opis proizvoda:

Breathable bricks are our company’s leading high-tech products. The material is chromium corundum or corundum-spinel, and the brick type is a directional slit type. After the product is formed, it is made by advanced technology such as special curing and high-temperature firing. It has the characteristics of high stability, high repeated blowing rate, long life, large air permeability, etc. It is the preferred structure for bottom blowing argon in ordinary ladle, LF, LF-VD, VOD, CAS-OB and other equipment, and is ideal for replacing imports. product.

The product has the characteristics of stable structure, large air permeability, high blowing rate, erosion resistance, erosion resistance, and long life. Conducive to purifying molten steel, uniform composition and temperature, suitable for refining furnaces for long-term treatment or special treatment of molten steel.

The breathable bricks produced by our company have always been of stable quality and complete varieties. It can be produced according to user requirements, and can provide matching supply of related refractory materials such as set bricks, seat bricks, and joint materials. At the same time, it can design and select breathable brick products for users to ensure the smooth implementation of the bottom argon process.

Glavna metoda oštećenja cigli propusnih za zrak je oštećenje toplinskim šokom. Uz kontinuirano povećanje temperature točenja, velika je razlika u temperaturi između radnog i isprekidanog rada na radnoj površini ventilacijske opeke, što zahtijeva da materijal ima visoku otpornost na toplinski udar. Spinel faza uvodi se u lijevano, a otpornost na toplinski udar cigle koja propušta zrak bit će poboljšana.

Oksid ili neoksid koji se dodaje u ventiliranu ciglu tvori fazu krute otopine s agregatom na visokoj temperaturi, povećava čvrstoću cigle na visokoj temperaturi, poboljšava propusnost opeke i odolijeva eroziji ventilirane opeke rastopljena troska u kutlači. Nakon visokotemperaturne toplinske obrade cigle koja propušta zrak, poboljšavaju se njezine performanse kako bi zadovoljila zahtjeve uporabe.

Our company develops and produces impermeable ladle bottom argon-blowing slit-type ventilating bricks. Because there is less cleaning or no cleaning during use, manual intervention is reduced, which can effectively reduce the abnormal melting loss of ventilating bricks caused by oxygen burning and purging. . Due to its scientific and reasonable formula, it can effectively reduce the loss of breathable bricks caused by thermal stress, mechanical abrasion and chemical erosion.
