Specifications
refractory ladle lining brick
1) Good thermal shock resistance
2) High-temperature endurable
3) Good thermal insulation
Description:
1. Good acid stability
2. Good thermal performance
3. Good thermal shrinkage
4 Good resistance to abrasion and corrosion
Advantage:
Fire brick is refers to the Al2O3 content is 30% ~ 40% aluminum silicate.Clay brick is made of soft clay and 50% and 50% of hard clay grog, ingredients required by certain granularity, after forming, drying, burning under the high temperature of 1300 ~ 1400 ℃.Clay brick belongs to the weak acid refractory products, can resist acid slag and the erosion of acid gases, the alkali resistance ability is a bit poor. Clay brick has good thermal shrinkage.
- Q: What is fireproof concrete?
- Silicate fireproof heat-resistant concrete using temperature can reach 700 DEG ~800 DEG, the main mechanism of its heat is dehydrated calcium hydroxide silicate hydrates series of cement clinker under high temperature, the calcium oxide and slag and mixing activated silica material in the three and two aluminum oxide and the reaction of anhydrous calcium silicate and anhydrous aluminum acid calcium has strong heat resistance, the fire resistance of concrete is a certain. Such as the use of high alumina bauxite and broken bricks, magnesia brick and magnesia for fireproof heat-resistant concrete materials with the highest using temperature can reach 1100 DEG C.
- Q: In 2016, a few of the traditional refractory materials will be able to survive
- The other is in large enterprises and individual has the unique advantage of the small enterprises, with independent technology system, production equipment advanced, there are certain funds set up to deal with risk, timely reform, such enterprises compared to a few years ago the productivity and sales or have declined, but overall is still in the stage of production increased steadily.
- Q: What are the main components of high alumina bricks?
- Sweat is like water mineral alumina bauxite, aluminum ore, magnesite, waves of gibbsite. Anhydrous alumina raw material, such as corundum, alumina, fused corundum. High alumina brick Zhengzhou gold company specializing in the production of various specifications, you can directly ask their technical staff.
- Q: What are the grades of high alumina bricks?
- High alumina brick according to the aluminum content is generally divided into: super high alumina brick, a high aluminum brick, two high alumina brick, three high alumina brick
- Q: What is the content of free silica in the refractory bricks of high alumina bricks?
- In the meantime, the free silica content of silicon brick is as high as 90% above. Therefore, the most serious damage is silicon brick, followed by clay brick, high alumina brick, magnesia brick and so on.
- Q: How much is one ton / ton of high alumina refractory brick?
- The price of high alumina refractory bricks is not equal, according to the quality index of GB2988-2012
- Q: How high can aluminum bricks expand at 80O degrees of heat?
- When an object is heated, the particle moves faster and thus occupies additional space. This phenomenon is called dilation.
- Q: What kind of material is the general metal case?
- We usually discuss the electromagnetic radiation of computer enclosures, mainly RF radiation, followed by MF leakage.Switch signal of RF radiation from computer high-speed leakage, such as one of the energy radiation is CPU frequency, graphics, display output line, keyboard, is the source of the operating characteristics of the computer leaked out, is also the main part of computer security.For the absorption of radio frequency radiation, the best is the use of copper materials, the use of other metals can also, thickness enough on the line.The most vulgar description is that people can sit in the case is a good thing.
- Q: How to reduce the harm caused by two times mullite in high alumina refractory material
- Prolong the sintering time and adjust the aluminum content of the high alumina brick.
- Q: What is the high temperature limit of refractory bricks and refractory soil?
- Fire clay -- usually refers to folk point stove furnace set with a kind of soil, limit under atmospheric pressure of 1500 degrees fire clay soil 1, properties and uses: clay brick of weak acid refractory material, its thermal stability is good, suitable for hot blast furnace, boiler and flue, smoke chamber lining, etc..2, product specifications form: standard shape, general, special-shaped and special-shaped brick. Physical and chemical properties of fireclay bricks.
