- Q: Can someone professionally introduce the classifications of refractories?
- Whatare the classifications of the refractory index levels? There are three categories of refractory index levels. Anyone familiar with the industry may already know that if you're new to the refractory and don't know much about it, the following information may be helpful to you. Refractory index level can be devided into three general categories of special refractories, advanced refractories and ordinary refractories. The first category, special refractories. Whose refractoriness is higher than 2000 ℃, spinel brick, pure oxide products, high purity directly bonded magnesia-chrome brick, cast products, non-oxide products belong to this grade. The second category, advanced refractories. Whose refractoriness is from 1770 to 2000 Celsius degrees, mullite bricks, high alumina brick, magnesia-alumina brick, ordinary magnesia products, olivine bricks, ordinary magnesia-chrome brick belong to this grade. The third category, ordinary refractories. Whose refractoriness is between 1580 and 1770 Celsius degrees, equivalent to Al2O315% ~ 45% refractory products in the binary system of SiO2-Al2O3. Kaolinite is the main mineral of raw materials.
- Q: What is unshaped refractory?
- Plastic. From the production method, the plastic is between the concrete and the castable. It is made of refractory material by refractory material plant, which is made of plastic clay. The ingredient is a retarder. It is packaged by plastic bag, and construction and heat treatment are carried out on the spot. But the biggest problem is the application of plastic on the knotted Jiecha easy peeling, retarder dosage improper or is vulnerable to bad caking plastic hardening.
- Q: What are the requirements of refractory temperature of refractory brick?
- Refractory brick, called refractory?brick for short, is refractory material made by firing refractory clay or other refractory raw materials. Faint?yellow or brownish, it is mainly used in building smelting furnace. It can resist 1,580 ℃ -1,770 ℃ high temperature.
- Q: What kind of material is refractory fiber?
- 1 Refractory fiber cloth can be divided into resistant to temperature of 600 degrees and 1000 degrees temperature resistant (short-term resistance to extreme temperature 1260 degrees). The thickness of two kinds of cloth is typically 1mm 1.5mm 2mm 3mm 4mm 5mm with the width of 25mm-- 1200mm. 2 Specially woven fiber is not easy to fall off, does not irritate the skin, has large tensile strength. It is white and inexpensive. After contacting with water, the tensile force will be reduced. The thickness of refractory fiber cloth whose resistance of temperature is 1260 degree is generally 2mm 3mm 5mm, and the width is 25mm - 1200mm. It has high temperature resistance, great tensile force, and it is non-toxic, white, resistant to fire and water. We can offer products with different specifications according to customer requirements. It has high temperature resistance, low heat conductivity coefficient, thermal shock resistance, and low thermal capacity; It has excellent high-temperature insulation performance and long service life; It has anti-melting and resistance to erosion of aluminum, zinc and other nonferrous metals; It has good strength under low temperatures and high temperatures; It is non-toxic, harmless, and environmental-friendly; It has convenient construction and installation; Specifications and models are 1.5mm - 6mm, with a general width of 1m, (nickel-chromium alloy wire reinforced, reinforced stainless steel wire, glass fiber reinforced, ceramic fiber coated fabrics, ceramics fiber slag cloth, sintered ceramic fiber cloth, ceramic fiber fumigation cloth). We can also provide other specifications according to customer requirements.

The mechanical properties of refractories include withstand voltage strength, tensile strength, anti bending strength, torsional strength, shear strength, impact strength, abrasion resistance, creep resistance, adhesive strength, and elasticity modulus. The usability of refractories include refractoriness, load softening temperature, linear?change?on?reheating, thermal shock resistant performance, slag resistance, acid resistance, alkali resistance, hydration resistance, corrosion resistance to CO, conductivity, and inoxidizability.
- Q: Who can tell somthing about how to choose fire resistant rating of fire resistance rolling shutter doors?
- According to the fire endurance, fireproof doors can be divided into A-grade, B-grade and C-grade, whose fire endurance should not be less 1.2h, 0.9h and 0.6h respectively. A-grade fireproof doors can be even applied to the material whose fire resistant rating is at secondary level. "Building Regulations" mention that fire resisting shutter can be used as partition of fire?compartment in those places where setting firewalls is not so easy. When using fire resisting shutter whose fire endurance includes unexposed surface temperature rise, its fire endurance should not be less than 3 hours. When using fire resisting shutter whose fire endurance doesn't include unexposed surface temperature rise, it should install closed independent automatic sprinkler system for protection on both sides, and the sprinkler sholud last at least 3 hours.
- Q: What are the requirements for fire?rating of construction suspended ceiling material ?
- In fireproof design of all parts in interior decoration, fireproof design of suspended ceiling is the most important. Because the flame is burning up in fire and the suspended ceiling is the first and most direct part to test fire; at the same time, it has a direct impact on the evacuation. Therefore, in indoor suspended ceiling decoration design, fireproof work should be considered fully. Code of fire prevention design of interior decoratio of buildings has detailed provisions for fireproof?performance of indoor suspended ceiling materiial of different civil buildings. Suspended ceiling (sprung roof) refers to the top decoration of a house. Suspended ceiling, an important sub-project in construction decoration project, and the hidden layer of electrical equipment, ventilation and air condition, communication and fireproof, alarm pipelines, etc. has the functions of thermal insulation, sound insulation and absorption. Suspended ceiling plays an important role on the entire house decoration. Proper decoration to the house top surface, can not only beautify indoor environment, but also create a colorful interior artistic image. When choosing decoration materials and design of suspended ceiling, you should follow the principle of saving material, being solid, safe, beautiful and practical.
