Element of each place damaged compares hearth of blast furnace crucible

Below reasonable liner construction, the choice of fireproof material is crucial. The research development that each place comes to in nearly 30 years with fireproof material obtained crucible hearth a lot of achievement. The BC-7S small Kong Tanzhuan that carbon pledges material is like Japanese NDK company, BC-SSR exceeds small Kong Tanzhuan

, charcoal of hot pressing of American NMA, NMD piece, french AM-101, AM-102, homebred brick of brick of charcoal of half black lead, small hole charcoal, tall heat conduction brick of charcoal of half black lead, exceed small Kong Tanzhuan to wait; Material of tall aluminous pottery and porcelain is like French MS4, MS4R, MONOCORAL, corundum of homebred corundum Mo Laishi, compound palm, grey corundum, tall aluminous firebrick; Mouth of blast tuyere, iron is like brick of silicon line stone, Molaishi with the brick the carborundum brick that brick of — carbonization silica brick, βSic—SiC, nitrogen changes silicon to be united in wedlock. These material are very good material, obtain initial effect on domestic and international large blast furnace. According to crucible hearth element of each place damaged is compared () laying a plan, fireproof material function compares Zhengzhou flourish to fill factitive Central Plains to be able to bear or endure material character, pay attention to the amplification of oneself dimensions not only, more important is to stand in long-term development point of view from beginning to end, ceaseless development gives new-style fireproof data, satisfy more firm market demand ceaselessly thereby, comply with the development of tendency of the day. Major of flourish Cheng Naicai produces all sorts of tall aluminous bricks, firebrick, argillaceous brick, pouring the product such as makings, welcome broad client to come to a factory make an on-the-spot investigation on the spot, establish long cooperative relationship.
