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.
Magnesian iron brick and magnesian chromic brick are two kinds of common fireproof material, they differ somewhat on composition, function and utility. Magnesian iron brick 1. Comprise brick of composition magnesian iron: Bases is magnesian (MgO) and ferric oxide (Fe₂O₃) . Generally speaking, the magnesian content in magnesian iron brick is higher, and ferric oxide content is inferior. ...
The function index of fireproof material affects what its fall in high temperature environment to use the effect directly. The function index that is a few keys below reachs his to be opposite the influence of use effect: 1. Fireproof degree: Definition: Ability of infusible of action of high temperature of fireproof material resistance. Influence: Fireproof degree taller, stuff is better in the stability below high temperature environment, not easy...
The heat conduction rate of tall aluminous brick is a when its heat up function important facet, in applying actually, can control through coming with lower part law and optimize the heat conduction function of tall aluminous brick: 1. Raw material chooses and deserve to compare tall purity raw material: Use the aluminous alumina of tall purity and other and fireproof data, can reduce foreign matter, improve integral performance of the brick. Add light...
Intermediate canister (intermediate bag) it is the crucial equipment in steely smelt process, basically install the molten steel that pours out of from steel-making furnace with Yu Cheng, control molten steel to flow into the speed of casting machine and quality. The fireproof data that uses inside inter canister must have good adiabatic performance, heatproof shake gender and be able to bear or endure aggressivity. It is the heat insulation with intermediate commonly used canister below...
The reason that fireproof material is eroded in environment of high temperature work is varied, basically include the following fields: 1. Chemistry erodes soda acid: Fireproof material can produce chemical reaction with acidity or basic material, bring about the destruction of material composition. For example, acidity slag can erode alkalescent firebrick. Oxidation erodes: In high temperature annulus...
Adiabatic brick is a kind of fireproof data that basically is used at liner of high temperature equipment, its are main the characteristic is rate of low heat conduction, can reduce loss of quantity of heat effectively, promotion the sources of energy uses efficiency. It is the main function of adiabatic brick and application below: Function low heat conduction leads: The coefficient of thermal conductivity of adiabatic brick is inferior, can cut off effectively quantity of heat is conducted, hold heat...
Checker brick of checker brick low creep is a kind of high-powered fireproof data, basically use at the checker place of furnace of kiln of high temperature industry, in order to improve the thermal efficiency of kiln furnace and service life. Its produce a process to involve select material, burden, shape, dry, firing wait for many measure. It is detailed manufacturing technology introduction below: 1. Select material and burden former...
Fireproof material needs to answer high temperature, thermal stress and mechanical stress in nonferrous metal industry. It is a few main strategy below: Choose relevant data: Alumina (Al₂O₃ ) : Have high melting point and good heatproof shake sex, apply to high temperature application. Magnesia brick (MgO) : The smelt metal that applies to the nonferrous metal that contain magnesium...
The stomatic structure of fireproof material has distinct effect to its creep function. Creep is to show material is mixed in high temperature constant below stress action, the plasticity that arises gradually along with time is out of shape. Stomatic existence can change the mechanical function of fireproof material and creep behaviour, material effect is as follows: 1. Air hole is right the influence mechanism of creep 1.1. Porosity is enraged high...
The kiln heat that is used at fire pottery and porcelain has a few kinds of kinds, every kinds of type has his characteristic, the pottery and porcelain that suits different type works. It is the type of main kiln furnace that uses in pottery and porcelain below: 1. Electric kiln characteristic: By electric power drive, heating element is made by the material such as Kandaer or nickel chromic alloy. Ideal temperature is controlled and but process designing sex. Actor...
Of Mo Laishi firebrick form Molaishi firebrick is main by Mo Laishi photograph (3Al₂O₃ · 2SiO₂ ) composition, in addition the vitreous photograph that still contains certain amount and other a few impurity. Mo Laishi is by alumina (Al₂O₃ ) with 2 oxidation silicon (SiO₂ ) form by specific scale...
The mortar that when firebrick build by laying bricks or stones is built, uses is called normally fireproof mortar, it and common structure mortar are different, use technically at the build by laying bricks or stones below high temperature environment to build a project. The fireproof mortar with right choice is very important, in order to ensure the integral structure stability of body of build by laying bricks or stones is mixed high temperature resistant function. It is a few commonly used kinds of fireproof mortar when firebrick build by laying bricks or stones is built below kind...
