- Q: Does anyone know the characteristics of refractory for glass kiln?
- The characteristics of refractory for glass kiln: First, it can well resist the erosion of glass?fusant and gas actor, and has sufficiently high load softening temperature and thermal stability. Usually we hope the refractories of all parts of the furnace will has no partial early erosion phenomenon to ensure that the entire furnace has a sufficiently long service life. However, due to the different mechanical, physical and chemical conditions of different parts of glass furnace, the performance of refractories should adapt to the glass furnace thereto and at the same time has no adverse effect on the adjacent other kinds of brick materials. Besides, we should consider the price of brick material, we should try to consider using commonly used stereotypes bricks of standard sizes which is cheap and quickly supplied by the warehouse. The damage of glass melting furnace lining is mainly due to chemical erosion, assisted by thermal stress. The degree and speed of chemical erosion is closely related to the applied parts, furnace temperature and melting glass varieties, and of course, the quality of the lining itself is also crucial. The nature of refractories using in the glass furnace has a very significant impact on the operation of glass melting furnace and the quality of glass. The application of poor main beam refractories will not only cause frequent shutdown for maintenance, limiting melting temperature, lowering furnace output, but also shorten the life of the furnace, and make glass has a variety of defects (stripes, stones, etc.), lower the quality of the glass. Here are the description of the nature and purpose of commonly used refractory in glass furnace.
- Q: How many kinds of A-level fireproof and thermal insulation materials are there?
- Shenyang polystyrene board, extruded sheet, polystyrene particles, and polystyrene plastic plates...
- Q: Kinds of refractory mortar
- Refractory mortar can be divided into ordinary refractory material and special refractory material. Ordinary refractory materials can be divided into acidic, neutral and alkaline refractory materials chemical properties. Special refractory material can be divided into high temperature oxide, refractory compounds and high-temperature composite materials according to their components. Furthermore, according to refractoriness, it can be divided into general refractory products (1580 ~ 1770 ℃), high grade refractory products (1770 ~ 2000 ℃) and super refractory products (2000 ℃ above). It can be divided into bulks (standard bricks, special-shaped bricks, etc.), special shapes (crucible, sagger, pipe, etc.), fibrous (aluminum silicate, zirconia filter and boron carbide , etc.) and indefinite shape (refractory clay, pouring materials and ramming mass, etc.). According to the sintering process, it is divided into sintered products, fused cast products and melting jetting products.
- Q: Application of refractory materials in petroleum industry
- Our natural gas transportation, chemicals, equipment, packing, safety, insulation, and even building materials are available.
- Q: Does anyone know about the classification standards of B2-level fireproof and thermal insulation materials?
- 1.The insulation materials with A-level combustion performance: EPS Hairong module, rock wool, glass wool, foam glass, ceramic foam, foam cement, closed-cell perlite, etc. 2. The insulation materials with B1-level combustion performance: specially-treated extruded polystyrene boards(XPS)/ specially-treated Polyurethane(PU), Phenolics, Polystyrene rubber powder particles,etc. 3. The insulation materials with B2-level combustion performance: Expanded polystyrene sheets(EPS), Extruded polystyrene boards(XPS), Polyurethane(PU), Polyethylene(PE), etc. See the 2009 measures of building technology. The A-level insulation material is only fireproof, the insulation performance of it is worse than that of organic XPS \\\\ EPS material. Currently I think that the best insulation material should be Hairong EPS module, it not only achieves the requirement of insulation but also fulfills the goal of fireproofing, and the comprehensive unit price of it is not expensive. The insulation materials in the domestic market have their own disadvantages, you'd better take the building demands into consideration, and use the materials that are within the acceptable range.
- Q: Manganese steel belongs to refractories
- Material wear and other harsh working conditions, extrusion, there will be work-hardening phenomenon rapidly on the surface. The most important feature of manganese steel is that it is not refractory under a strong impact, and under extrusion conditions, part of it will be fractured. The main form of damage is wear and consumption: It is a kind of inorganic non-metallic material whose refractoriness is not lower than 1580 ℃, mainly used to endure impact. Manganese steel is a kind of high strength steel, which is free of deformation, so that it can remain austenite good toughness and ductility at heart while keeping good wear resistance at the same time on hardened layer. Refractories are

- Q: Firing high temperature kiln of refractory and internal temperature being as high as 1600 ℃, metal heat exchanger can't use, how to do?
- 1>3>。 When metal heat exchanger is in 700 ℃, it must process high temperature protection, mixed cold wind or cold blast to protect heat exchanger. So this will waste a lot of energy; The comparison of high temperature resistant ceramic heat exchanger using temperature is 1350 ℃ to 1450 ℃; metal heat exchanger using temperature 700 ℃; heat utilization comparison of ceramic heat exchanger can be placed in 1350 ℃ or higher (highest available to 1450 ℃); the oxidation resistance, a very short time will burn out;2 >, waste heat recovery rate is high. Replacing the metal heat exchanger in high temperature and corrosion environment; Comparative ceramic heat exchanger can be used under the condition of 1350 ℃ for a long time. Let's make a comparison, if it is a refractory material industry. <, ceramic heat exchanger is simply won't appear, under the condition of equal to ceramic heat exchanger using, energy saving effect is best, can exchange for the high temperature. <. Ceramic heat can be placed on the nearest of exchanger flue outlet . <, and metal heat exchanger put in place contrast to the ceramic heat exchanger. In the process of using metal heat exchanger, if this situation happens, you can consider the ceramic heat exchanger. Temperature difference is between 650 ℃ to 750 ℃. If the metal heat exchanger is placed in normal place where ceramic heat usually put;The service life comparison: since ceramic heat exchanger with high temperature resistance, this partly replace metal heat exchanger. What's more, energy-saving rate is also different. Metal heat exchanger can be placed in 700 ℃ or less;4 >, corrosion resistance, its application effect is very different. So the metal-heat-exchanger's heat-resistant temperature is high and the service life is the countless times of metal heat exchanger. The place with highest temperature does not need high temperature protection.

- Q: Fire insulation and fireproof insulation board materials What is the difference in performance?
- What is the difference between fireproof insulation board and fireproof materials in their performance? Fireproof Materials prevents burning through insulating while others by chemical reactions. The overall heat conductivity coefficient of Insulation materials are generally lowered by thermal conductivity of the material itself and the structure of the material. Inorganic active insulation material uses ordinary cement, insulation stone, calcium powder, platycodon grandiflorum as the main raw material, produced after numerous tests with advanced production technology and chemical technology. Products features fire retardant,anti-aging properties and stable performance, low deformation coefficient, environmentaly friendly, compatible with the wall base layer and plastering layer. It has good security and stability and is as durable as ordinary buildings. Strong fire resistance: Fire insulation board is made of inorganic materials (cement), fireproofing level reaching to A1. As it does not burn, it is fireproof.
