Product Description:

Ladle upper nozzle & collecter nozzle
With the characteristics of high strength, good thermal shock resistance, oxidation resistance, scouring resistance, erosion resistance, small reaming and long service life, etc.

Long nozzle
They have excellent properties of thermal shock resistance, abrasion and corrosion resistance, bake free and long life.
Breathable ring is composited inside nozzle bowl, achieves argon-blowing protection of nozzle end, and prevents secondary oxidation which satisfying requirements of high pure steel.

Submerged nozzle
They have excellent properties of abrasion resistance and oxidation to molten steel, thermal shock resistance, corrosion resistance to slag.
The nozzle outlets are special handled by materials with good abrasion resistance in order to guarantee stable outlet angle of molten steel, and satisfy requirements of molten steel flow field design of crystallizer and production, which ensure stable liquid level.

Q:What kind of refractory brick is used for industrial furnace?
High aluminum in cement plant. Mills use MgO-C, high aluminum ect; glass furnaces use Luo 8. different kiln and parts use different bricks.
Q:Can fly ash brick keep warm?
Sure, I do fire-resistant insulation bricks, we also use fly ash ah!
Q:What types of refractory bricks are divided into?
Chimney and flue are places that high temperature gas of sulfur gathers, it should use acid material. Refractory material is divided into three major parts: acid, neutral and alkaline.
Q:What is light brick and what are the characteristics of light brick?
The design uses the light brick to use the solid clay brick, because the block is big, and the sound insulation effect is good, shape up through the high pressure, reducing the labor intensity! Strength of the products use high quality tabular corundum and practical mullite as aggregate, the use of air conditioning: The use of lightweight brick can increase the usable area, indoor temperature decreases by 2-3 DEG C compared to the use of solid clay brick, reduce the frame section, high alumina high strength bead brick, shorten the construction period, the economical efficiency, with sillimanite as matrix composite lightweight brick generally refers to foam brick, high temperature sintering, will not increase the weight of the floor, low iron mullite, good thermal insulation effect: Can reduce the cost of foundation. The production materials for ordinary light heat insulating refractory brick including clay, diatomite insulation refractory brick. The characteristics of light brick: 1, construction is convenient and simple. 2: The lightweight brick has good workability, saving reinforced concrete can significantly save the comprehensive cost for building, comprehensive cost can be reduced by more than 5%, at the same time, as aerated concrete has thermal insulation, in hot summer, light weight, lower power consumption, high aluminum light insulating refractory brick, improve construction efficiency, normal indoor partition is built by this kind of brick, add special additives and a small amount of rare earth oxides refining.
Q:What raw materials are used for making refractory bricks
That is silicon aluminum refractory brick/, it can be divided into five types:thermal insulation refractory brick, alkaline series refractory brick, refractory brick containing zirconium, carbonaceous refractory brick/. Refractory bricks are divided according to the ingredient of refractory. Refractory bricks are generally made from refractory clay (kaolin) or other refractory materials.
Q:What's the difference between zirconium and zirconia? What are the fields in which applications?
Fused zirconia is mainly used for refractory materials, such as zirconia bricks, and used in crystal materials, such as making diamond, and making high-temperature resistant coatings, etc. ~!
Q:What is the difference between high alumina brick and clay brick?
There must be a difference. They vary in color from the amount of aluminum, the weight, the temperature, and the color. For example: 75 high aluminum and 43 clay bricks, 75 single weight 4.5kg or more. 43 3.65kg or so, the use of temperature 75, high aluminum in about 1520, 43 of brick 1430 or so, the color of 75 pan white, 43 of the Loess color. In short, the difference is great.
Q:What are the properties of corundum mullite
Heavy material has good compactness, high compressive strength, resistance to various corrosive gases, good thermal shock resistance, good thermal conductivity and wear resistance.
Q:Difference between low creep high alumina brick and ordinary high alumina brick
Low creep and high alumina brick is based on the theory of "three stones". The combination of bauxite and clay as the main raw material, adding kyanite, andalusite and sillimanite, commonly known as the "three stone" control, physicochemical index and size composition, using alumina mullite corundum + + raw materials such as technical scheme. In the production process, first to detect and control indexes of raw materials, crushing, grinding, sieving process, according to the distribution ratio of ingredients, the size and moisture control of mud mixing after to meet the requirements of forming and molding machine, the use of qualified abrasives, blow molding control number, size and flash at the same time, the detection efficiency of semi-finished products and meet the requirements. Production process: high temperature calcination of high-grade alumina, adding small creep rate of high temperature materials, by high-pressure molding and high temperature firing. It has the characteristics of high strength, low creep rate and high use temperature. Widely used in high temperature furnace, hot air furnace hearth lining, brick and so on.
Q:What's the price of lightweight refractory bricks?
Insulation bricks according to size, material, performance of different prices are not the same, the same products in different regions also vary slightly
