Product Description:

 

1.Structure of Calcined Bauxite Description

Bauxite (aluminous soil; Bauxite) is also called the alumina or bauxite, main ingredients are alumina, hydrated alumina containing impurities, is an earthy mineral. White or gray, brown and yellow or light red by iron.  From 4 to 3.9 g/cm3 density, hardness, 1 ~ 3 is not transparent, very brittle. 

 

2.Main Features of the Calcined Bauxite

Calcined bauxite is one of the principal ore of aluminum. Calcined bauxite contains hydrous aluminum oxides and aluminum

hydroxides, formed through the laterization of aluminous rocks in tropical and subtropical areas .

Q:What are the electrical fire protection materials?
Electrical fire protection materials are the following: 1, fire proof board It is the most commonly used materials in the market, which has the advantages of fire prevention, moisture, abrasion, oil, easiness to clean, and more varieties of colors. Installed in the building exit corridors, stairs and corridors, such as fire ceiling ceiling, it can ensure that people can be evacuated safely, and to protect people from the spread of the fire. 2, fire proof door, fire proof door is divided into wooden fire door, steel fire door and stainless steel fire door. Fire proof doors are usually used for the opening of the firewall, the entrance of the staircase, the evacuation of the aisle, the openings and other parts of the pipeline, the fire prevention, playing an important role in reducing the loss of fire. 3, fire shutter It can be set in the location where it is not convient to install a fire proof wall, fire shutter generally has functions such as good fire resistance, heat insulation, smoke, compression, anti aging, wear and corrosion. 4, fireproof and mothproof wood fire wood moth is made by putting ordinary wood into the solution containing calcium and aluminum, and then into the solution containing phosphate and silicate. In this way, two ion will be undergong chemical reaction in the wood, forming materials similar to the ceramic, and filling the gap of cells and tissues, so that allowing it to have fireproof and mothproof performance.
Q:What kind of materials are needed to make refractory bricks?
According to requirements, there are different materials, acid refractory material, such as silica bricks; neutral refractory material, such as high alumina brick; and basic refractory material such as magnesia brick.
Q:Can anyone tell me what is a high alumina refractory?
High alumina refractories: High-alumina refractory products have high refractoriness, compressive strength and refractoriness under load, which are used for building the high-temperature parts of various large blast furnaces, such steelmaking furnace, airheater, electric furnace, rotary kiln and other thermal equipment.
Q:The development prospect of fire-resistant material
Luweishi (Furnace guardian)--- the wings ofrefractory material (blast furnace for high pressure grouting and liningmaking)--- is the fortune of furnace repair companies. Nowadays the sales of refractorymaterial are very difficult, but furnace repairing is popular. It does not onlyearn money but also sell refractory material, and even establish long-term,stable and interdependent business relations provided the price is acceptable.Many forward-looking companies such as Beijing Rongda, Anshan Yongheng, WuahnKehong, Shandong Zhangqiu, Gongyi Huaxi, Hongda, Zibo Xinfu and Anyang Tecai,allowing for the steel mills which are rich and try to do things the easy way, turnrefractory plant into or include into building company, resulting in greatsuccess in the bid invitation among so many units. Junwei can provide quality and efficient blast furnace equipment for grouting and lininLuweishi--- Luweishi (Furnace guardian) and research, design and manufacture as required. QQ:76350883
Q:I want to know what is the slim in the refractory bricks
Where are you from, I can introduce to you
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:What are the technical requirements for refractories?
To put it simply, physical indicators are pores, volume density, pressure resistance, slag resistance, thermal shock resistance, foot expansion coefficient, thermal conductivity, oxidation resistance and so on. If it is castable, the indicators are mobility, water rate, setting time, and anti bending strength. If it is coating mix, the bonding strength should be checked. Chemical indicators are loss of ignition and the content of aluminum, magnesium, silicon, calcium, chromium, titanium and carbon.
Q:Why does refractory need to add coarse firstly and then add fine aggregate?
Oh, adding coarse aggregate first is to select good material to make aggregate, and the rest cna be made into fine aggregate. Because if it contains impurities, once being sintered, the appearance will be affected, but fine aggregate does not have this impact.
Q:What are the classifications of refractory? Which category does steel ladle castable belong to?
In addition, it can be divided into refractory, shapeless refractory material. And it can also be divided into acidic refractory, basic refractory and neutral refractory. If you want to know more, you can ask thme. In fact, every company has different refractory clasifications. There are more clasifications in Huaheng.
Q:What is the common inorganic fireproof and thermal inuslation matertial?
1. The thermal insulation material of level A combustion performance: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3 combustion performance is level B2 insulation material: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), sea capacity module and vitrified micro bead.
