Product Description:

Converter Tap Hole Stopping-Slag Slide Plate

Pure zirconia plate is inlayed in the important region of converter tap hole stopping-slag slide plate. The matrix is made of stable medium and high temperature AZC materials,which has long service life, excellent effects of stopping-slag.

Medium or high temperature sintered Sialon bonded sliding gate at N2 atmosphere
Independent research and development of new sliding gate by importing special sialon additives, sintering at the medium our high temperature of N2  atmosphere. In the process of sintering create the sialon phase with good medium or high temperature performance, thus improved the high temperature compression strength and the breaking strength. The using effect on the large and medium-sized steel ladle and the tundish is good.

BOF taphole slag slide gate mechanism
Using the mechanism of BOF slag could recovery slag effectively in the furnace. And slag splashing protection technology could increase converter furnace which can solve the problem of irregular erosion in taphole. By the new process of slag controlled tapping , can improve the alloy yield, and can also greatly save the amount of aluminum addiction, the comprehensive cost reduction is considerable, and it also improved the economic efficiency and the competitiveness of the products in the market, it’s the first choice of equipment for smelting high quality steel.

Q:What's the difference between high alumina refractory bricks and high alumina refractory bricks?
High alumina refractory brick in all thermal shock properties except performance are better than clay refractory brick, masonry in furnace and thermal equipment, such as clay bricks can be competent the work environment is not high aluminum brick masonry.
Q:do the used refractory bricks pollute the environment?
the main pollution of refractory brick is coal gas pollution in the process of burning , it can be recycled to produce aggregate, waste brick has no pollution.
Q:What's the weight of the refractory bricks?
Fireclay refractory bricks: 3.4kg-3.8kg - according to the quality of raw materials, prices ranging from 1 yuan to 2.7 yuan, high alumina refractory brick: three, high aluminum in 3.9kg or so. Ordinary T-3 firebrick weight calculation method: 230*114*65*2.2/2.1.
Q:What are the main constituents of refractory bricks
Brick, refractory brick is containing more than SiO293%, is the main varieties of acid resistant brick. It is mainly used for coke oven building, also used in furnaces all kinds of glass, ceramic and carbon calciner, refractory brick arches and other load-bearing parts, is also used in high temperature bearing part of hot blast stove, but should not be used in thermal equipment below 600 DEG C and the temperature fluctuation in the.
Q:Process for producing magnesia chrome brick
The fine powder compacts after calcination produced by magnesia - chrome ore grinding method, brick with magnesia coarse particles, are effective measures to eliminate the effect of loose. Compared with the common magnesia chrome brick, the magnesia chrome brick made by this method has lower porosity, higher compressive strength, higher softening temperature and higher flexural strength. Compacts with chrome magnesite powder, magnesia chrome brick by synthetic magnesia chrome sand made of high-temperature calcination, slag resistance and high temperature strength are better than other magnesite chrome brick.
Q:What are needed to make refractory bricks with micro silica?
Micro silicon powder is used in mortar and concrete, the ore-smelting electric furnace produces a large amount of strongly volatile gases SiO2 and Si, bridges, seaports. It is ferroalloy. When smelt ferrosilicon and industrial silicon (metallic cilicon), micro silicon power is also called silica fume or condensed silica fume, dam, gas emissions and air condensate and deposit by rapid oxidation, water conservancy, airport runway, tunnel, high-rise buildings, subway, railway, highway and culvert. Application fields of silicon power are cement concrete pavement and mine roadway anchor reinforcement and etc.
Q:What is the maximum temperature range of high temperature resistant insulation materials?
High temperature insulation materials have many, the highest temperature range, specific material.For example, refractory bricks can withstand high temperatures between 1580 and 1770 degrees Celsius
Q:Refractory bricks in cement kilns are dangerous wastes
Magnesia chrome brick: Hang kiln, used for firing zone, the disadvantage is the poor thermal shock resistance, plus six Cr price is highly toxic, the production and use of the national magnesia chrome brick is gradually reduced, the brick production unit as soon as possible to find alternatives.
Q:Refractory bricks (mullite bricks) can be used on the walls of buildings?
Mullite refractory bricks can be used in construction, but their price is too high. We choose high alumina brick to meet the demand.
Q:What are the differences between sintered bricks and refractory bricks?
Sintered bricks belong to a type of refractory bricks.
