Bauxite is a natural, very hard mineral used predominantly in road systems for its high-friction and anti-skid properties. The majority of public sector systems will specify that Calcined Bauxite be used in their road and pedestrian crossing installations.

Its hardness is also beneficial in internal and external industrial flooring applications where a very hard and long lasting mineral is required to give high-friction, anti-slip performance.

Pigmented Bauxite, which is produced in-house and is available in the main safety colours, is used to give an element of high visibility to anti-slip and anti-skid decorative surfaces.

1.0 - 3.0mm particle size is shown for pigmented bauxite.

It is used extensively in warehouses, loading areas, high visibility pedestrian and vehicular safety areas.

Q:who knows the requirements of refractory for forge furnace?
Requirements are as follows: 1, it should have enough refractoriness and softening point under a fixed load. Because under the effect of electric arc, inner surface temperature in different parts of furnace lining can reach 1500 ~ 1800 ℃. 2, it should have strong slag resistance. Because slag and smoke at high temperature penetrate through furnace lining to its internal lining, causing the melting of refractory, organization stratification, and even peeling off. 3, it should have good thermal shock resistance. Because in the process of steelmaking, openning the oven door and lifting the furnace lid will make temperature of refractories in the furnace lining change rapidly, it might happen peeling off and cracking, causing the premature failure of furnace lining. 4, it should have sufficient strength, because the furnace lining will be shocked when being loaded, vibrated when being tilted, scoured by metals,molten slag and air flow when boiling. 5, smaller thermal conductivity, lower electrical conductivity. Commonly used refractories for electric furnace include magnesia bricks, dolomite brick, high alumina refractory brick, siliceous refractory brick and magnesite ramming material,etc. owing to the different work environment of each part of the furnace,refractory used by each part is also different.
Q:What's the organzational structure of refractory material?
Although hacing same chemical composition refractory material products also is mineral organizer. There are differences in the type of mineral phase, high refractoriness under load, quantity and crystalline state. The organizing minerals and microstructure are reflected by folding strength, high temperature pit definite density torsional strength, high-temperature torsional strength and product property. But, for example, wear or crack may cause damage. The performance index can reflect the internal structure of refractory: the nature of the thermal performance---linear expansion coeffcient. And the mineral composition of refractory material depends on the chemical composition and process conditions, the heat capacity and temperature conductivity. If the processing conditions are different, the influence of chemical action, and thermal conductivity: represents the nature of the mechanical properties - normal temperature, high temperature compression strength, high temperature creep performance and elastic modulus. Chemical compositions are the basic characteristics of refractory, representing the nature of the density---porosity, corrosion occurred refractory materials in high temperature use As a result, the composition and quantity directly determines the performance of refractory, true density: representing the forming of high temperature performance --- refractoriness, high temperature volume stability, so you can't analyze the effect on the product performance just from chemical composition. The performance of various refractory materials are different. It must be emphasized that macroscopic organization structure of refractory material is also an important factor that affects performance; reflecting complexity of penetration---air permeability, thermal shock resistance and slag resistance. The main component is the foundation of refractory characteristics.
Q:What are included in wall fireproofing material?
Wall fireproofing materials include dry wall and gypsum block. Dry wall is made into board material through process by using building plaster as main material, adding an appropriate amount of additive and fiber to make board core and using tailor-made board paper as protection surface. Dry wall ia characterized by light weight, sound insulation, heat insulation, strong processing performance and easy construction method. Gupsum block is lightweight building plaster product made by using building plaster as main raw material, adding water, stirring, moulding by casting and drying. Fiber reinforced material or lightweight aggregate are allowed to add during the production and foaming agent can also be added. It is soundproof, fireproof, convenient to construct and many other advantages. It is a kind of new wall material with low carbon, environmental protection, health and in line with the development requirements of the times.
Q:what kind of refractories is used to make the industrial silicon furnace mouth long life?
Fused zirconia corundum brick, the smelter of the glassworks is used this kind of lining, and you can contact by private letter.
Q:What types does soft fire prevention materials have?
Species: Finishing fire retardant paint, component fire retardant coating, fire-resistant coating for steel structure and othe kinds of fire retardant coating. Flame retardant plastics and its products, textiles, building materials, flame retardant fabric and exterior wall thermal insulation system products, floor materials, such as various types of fire prevention materials;Fire prevention board, fire doors, fire resistant window frame.
Q:What high-molecular polymers can be used as fire-resistant material binder?
Organic silicon
Q:Is it necessary for the frame of glass fireproof door to be crammed with fire-proof material?
Close the door , and check if the gap is normal, whether the hole and the door leaf are in the same plane, and whether the door leaf has tendency to fall down. Fire resistance steel door——means that use a cold rolled steel sheet as door frame, door plank and framework, and stuff a door leaf with incombustible material.
Q:What is the the best ratio of mortar in refractory cement?
The ratio of refractory cement are: M10 the ratio of cement and mortar: cement: Sand= 346kg: 1631kg M7.5 ratio of cement and mortar: cement: Sand =274kg: 1631kg M5 The mix proportion of cement and mortar: cement: Sand = 209kg: 1631kg M10 mix proportion of composite mortar: cement: Sand: Lime =306kg: 1600kg: 29kg M7.5 mix proportion of composite mortar: cement: Sand: Lime =216kg: 1600kg: 64kg M5 The mix proportion of composite mortar: cement: Sand: Lime =205kg: 1600kg: 100kg
Q:What are the fire resistance ratings of the glass partition?
When the inner structure of the system is steel structure, the fire resistance of which is 30 mins, 60mins or even longer. The partitions in the usual sense are walls that have a distance to the ceiling. The fixed partitions directly touches the ceiling are partition walls which should be required in accordance to the specifications of walls. If the partition is far from the ceiling, the fire protection requirements are relatively low. Partitions which combustion performances are no less than B1 level are safe enough, while partitions of places such as shopping malls have to reach A-level in terms of combustion performance.
Q:What material is used to make furnace pipe of refractory bricks?
Furnace pipe of refractory brick is an indispensable part of casting cupola. Furnace pipe is divided into upper and lower part. Radial direction and axial breathing. The upper furnace pipe adopts double layer steel structure and countercurrent air supply mode. The lower furnace pipe is made by processing integrated heat resistant steel in flange, fin and inner wall in wearing parts. The operation life is over 3000h. There is radiating rib of heating air on the edge of furnace pipe liner by using the heat of casting cupola to heat air in cupola. Hot air temperature is about 180-250℃, which contributes to improve trhe thermal efficiency of production equipment, decrease production cost and improve economic benefit of enterprises.
