Ronghua Refractory Technology Co., Ltd. focuses on the research and development and manufacturing of refractory materials and has cooperated with many high-temperature companies around the world for many years.
1, splash broken bits to protect furnace technology: After converter tapping, leave one part residue, add agent changing broken bits (magnesian ball or burn dolomite gently) , raise content of the MgO in broken bits, oxygen gun blows oxygen, make broken bits is splashed case, hang on bricky wall, every furnace, china is used completely almost. 2, concussion area is repaired makings (big
The carborundum that different union combines carborundum together to make different sort namely is fireproof material. Does common combinative form have: ? ?Si3N4) of of of rare ⒌ of Min of of word of of rare ⒛ of Min of technetium of of wholesale of two Min rare ⒀ combines punish, recrystallization (R-SiC) and silicon of reaction agglomeration ooze. Carbonization
Boiler is common problem one, the problem in exercise 1. Wear-resisting is pouring like expecting in the chamber of a stove or furnace close look area resembles Yu Lin, fall off, bare even pinhead, 105 Mm210 Mm of the largest area. Rising head of 2.U circumfluence a powerful person is put in a lot of Zhou Xiang crackle, the greatest flaw is 5mm about, u circumfluence a powerful person is exported
Raise furnace wall the technical measure of fireproof material life: 1, big crystallization magnesia: Tall purity, low SiO2, B2O3, tall CaO/SiO2, grain is more than 150m 2, high pure black lead: Phyletic, particle size distribution, purity 3, additive: Al, Si, Mg, alloy, boride (ZrB2,
The requirement that plants according to place steel-making goes to the purify of the quantity that contain carbon in cast iron formulary limits, make the content of other element decreases or the process that increases formulary scope. Say simply, it is opposite iron falls carbon, go the process of content of the sulfur phosphor, manganese that move silicon. This one process basically is
Prejudicial hearth tapping (EBT---Eccentric Bottom Tapping) ) 1, tapping mouth brick uses brick of high strenth magnesian carbon (C20 ％ ) , Al2O3 - SiC - C brick 2, tapping mouth drainage is arenaceous: A. Magnesian olivine B of carbon black of ＋ magnesia ＋ . Magnesian calcic iron sand is new-style tapping technology: 1, CBT (in
How much is the melting point of brick of Mo Laishi heat preservation? Of brick of Mo Laishi heat preservation fireproof degree very tall, highest and OK counteractive the high temperature of 1800 Celsius, but in 1600 to 1700 Celsius when heat preservation brick can begin bate, the melting point of brick of Mo Laishi heat preservation is to be in 1790 degrees or so, next
The function of magnesian calcic iron sand: Mineral photograph is characteristic of MgO, C2F, C4AF, C2S, C3S: C2F content is high, agglomeration is admirable, it is good to fight FeO aggressivity, fight broken bits qualitative thermal insulation of ability of osmotic strong position an asbestine board, diatomite pink is spread on, brick of heat insolation of flat build by laying bricks or stones is permanent on its the layer is burned
LF furnace (LADLE FURNACE) namely steel wraps finery, it is equipment of the fine outside the main furnace in steely production. LF furnace points to the finery in steely industry commonly, actual a kind of be electric arc furnace special form. LF lining mars an element: (1) chemical reaction and frit corrode; Broken bits and brick
Siliceous calcium is adiabatic board by hard silicon calcic stone hydrate is mixed enhance fiber to comprise, do not contain asbestos, highest heat-resisting temperature 650 spend or 1050 degrees, it is a kind of efficient energy-saving and adiabatic product. Product characteristic 1. Good wear, can bear the successive thermic load inside high temperature limit.
1, electric frit magnesia: MgO97.5% , caO/SiO22, big crystallization 2, scale black lead: Scale black lead 3, bond: Colophony of phenolic aldehyde of hot solid sex 4, additive: Al pink, Si pink, B4C, Al - Mg alloy 5, additive action mechanism: Precede over of A, additive carbon and oxygen reaction;
Main fine craft: 1, LF(Ladle Furnace Process) ; 2, AOD(Argon-oxygen Decaburizition Process) ; 3, VOD (Vacuum Oxygen Decrease Process) ; 4, RH (Ruhrstahl Heraeus Process) ; 5, CAS-OB(Composition Adjustments By Sealed Argon -o
