Description:
SIMAS65 is a kind of sintered spinel made of high purity alumina powder and high quality active
magnesia, sintered at super-high temperature. It has low creep rate, small thermal expansion
coefficient, the strong ability of anti-chemical corrosion.
Applications:
SIMAS65 is used for making high quality castables for ladle and for con-casting slide plates, SIMAS65 is also widely used for making blast furnace hearth, stove and ceramic kiln.

- Q: Who can tell me what is neutral refractory?
- It is a material that can resist acidic and basic slag, flux and chemical erosion form other refractories at high temperatures. The main components include carbon, silicon carbide, aluminum oxide, chromium oxide and other trivalent oxides, such as carbon refractories and chrome refractories, etc. Strictly speaking, neutral refractories refer only to the carbonaceous refractories, including carbon brick and graphite silicon carbide products, etc. Sometimes, high alumina refractories with high Al2O3 content also belong to this material, such as some materials that are acidic but tend to be basic refractories, like sillimanite, mullite bricks and corundum bricks. Recently developed aluminum carbon bricks, zirconium carbon bricks alumina - silicon carbide - carbon bricks, silicon nitride bonded silicon carbide brick and so on are also neutral refractories. This material can be used in the bottom of blast furnace, the lining of hearth and bosh, and the lining of aluminum electrolytic cell, calcium carbide furnace, ferroalloy furnace, molten steel ladle, plating tank, reaction tank, and autoclave and so on.
- Q: What are the applications of refractory in petroleum?
- It can be used in chemical filler. For general process, some insulation parts also need to use refractory.
- Q: What are the refractory materials above 1000℃
- It is a piece of cake to meet your requirement, anyway you can try unshaped castables like corundum and other refractory materials used in steelmaking which are above 1500℃ basically .
- Q: How to do environmental impact assessment for refractory Co., Ltd.
- The preparation of a report or statement. During the compilation process, any problems should be actively communicated with the construction side. For example, dust collector selection, environmental protection investment, total emission approval. (especially the total emission, you must let the construction side and communicate with the environmental protection bureau to get the total amount, otherwise you write the EIA does not make any sense.) Generally speaking, the preparation of the report is longer, about forty days; and the preparation of the report table is shorter, about fifteen days.
- Q: What refractories have good mechanical property resistance and heat expansion and cold contraction property?
- Aluminium oxide ceramics. I would like to know that what kinds of refractory materials can combine together and what kind of masonry way can be used for these materials so as to achieve the perfect combination.
- 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: What's the difference of fire-resistant material's density, specific gravity and bulk specific gravity?
- It usually used to test lightweight refractory. Density can be divided into apparent density (usually called as density) and true density: apparent density includes blow hole inside the sample; Unit weight is using quality to divide volume of sample and specific weight is used to represent liquid.
- Q: What are the new refractories?
- Sintering zirconite. I produce the refractory in Zibo.
- Q: I am a refractory material manufacturer, sold products, money is always not back, anxious to die, what is the way?
- Looking for refractory materials network, you can conduct online transactions, funds guaranteed
- Q: Are the rubber insulation materials are refractory materials?
- Compared with the fireproofing properties, the main thermal insulation properties of level B1 will be carbonized and drop when it is over 200 degree. <p class="answer-refer mt-10 f-light-gray" accuse="aRefer"> Reference: It is provided from technicians of Guangzhou Ou Fu construction materials: The answer that has been got:
