Q:What do RH and DH stand for in refractories?: DH :For human intelligence (diameter, board of directors). )

Q:What's the fire?retardant material of roller shutter fire resistance door ?: I am happy to answer this question. Fire resistant rolling shutter door is generally filled with aluminum silicate fiber cotton inside. fire resistant rolling shutter doors are divided into special inorganic fireproof rolling shutter door and steel fire resistance rolling shutter door. The former has better fireproof?performance, but the later has certain wind load resistance and can be installed outdoors.

Q:Classification of porosities in refractories and their effects on properties: Effect of apparent porosity on properties:The porosity is high, the volume density is low, the structure become more loose, generally low strength, corrosion resistance worse (slag infiltration and erosion along the hole toward the inside), but to improve the thermal shock resistance (resistance to thermal shock and not damaged).

Q:What are the specifications of refractory kilns ?: Rotating equipment is widely used in mechanical, physical or chemical treatment of solid materials in building materials, metallurgy, chemical and environmental protection industry. Such equipment is called rotary kiln. The best materials are magnesia-chrome bricks, unfired magnesite-chrome bricks, silmo bricks, magnesia-alumina spinel bricks, magnesia calcium zirconate bricks, iron magnesia bricks and castables.

Q:Refractories for iron-making blast furnace?: This question is too professional - as far as I know, there are blast furnace noumenon bricklaying - trough slag runner fire-resistant model ~ main channel carbon rod ~ ramming mixes ~ ~ I do not know the specific details.

Q:What advantage and disadvantages it has compared to common fire insulation materials: Advantage and disadvantages of A-level heat perserving materials of equal effectiveness 1, the component materials of A level thermal insulation materials are inorganic materials, so it is high temperature resistant, non-combustible, fire-resistant; 2, good durability, aging resisitant, and having the same service life as buildings; 3, a level thermal insulation material can be well combined without using polymeride to bond, coat mortar, reinforced net, needing only few construction procedures. It is anti seepage with few quality problems; 4, absorb few water, and can bond firmly with the cement mortar, tile adhesive tile, safe and reliable; 5, a level thermal insulation material have the same service life as buildings, without the need to increase the cost on maintenance and renovation during its life span, and can maximize resource conservation.

Q:How to prolong the furnace age of Induction furnace by using fireproof materials?: magnesia solid materials have thermal endurance and erosion/ performance and its change of temperature is likely to cause cracks. properties of materials (aluminum) in such case have to be taken into consideration.

Q:Can I use ordinary cement with the addition of sand, clay, and salt as refractory material to paste the stove?: You can add some hair, sand, yellow mud and some salt, but don’t use cement, it would lead to a thermal explosion.

Q:What's the heat conductivity coefficient, specific heat capacity and density of the refractory material of magnesite-chrome brick and magnesia-alumina brick respectively?: It is suggested that you find some samples of well-known manufacturers, such as Ogilvy and Mather Group, and that will be more correct.

Q:hat kind of fire retardant materials are there: At present, there are mainly organic and inorganic flame retardant materials, halogen and non halogen. Organic flame retardant materials are represented by bromine, nitrogen and phosphorus and its compounds; Inorganic fire retardant materials include antimonous oxide, magnesium hydroxide, aluminum hydroxide, and silicon. Generally speaking, organic flame retardant materials have a good affinity, and can be added in the plastics. Brominated flame retardant agent occupy the absolute advantage among organic flame retardant system, though it’s “controversial” in terms of environmental protection, it has been difficult to have other flame retardant system replaced.
