Ronghua Refractory Technology Co., Ltd. focuses on the research and development and manufacturing of refractory materials and has cooperated with many high-temperature companies around the world for many years.
Arc furnace ladle linings are essential components in steelmaking, safeguarding ladles from the extreme conditions of molten steel. These linings endure intense heat, chemical corrosion, and mechanical abrasion during steel transfer and treatment processes.
Practical experience has proven that rotary kiln or cement kiln incineration technology can handle industrial hazardous waste in solid, liquid, and gaseous states, making it one of the most widely used hazardous waste disposal technologies today. As of July 2019, there were 75 cement kiln co-processing projects (excluding Hong Kong, Macao, and Taiwan) in China that had obtained hazardous waste operation licenses, with an approved disposal capacity of 4.6252 million tons. Currently, cement kiln co-processing of hazardous waste mainly involves solid hazardous waste, liquid waste, and RDF (refuse-derived fuel) as alternative fuels, which are fed into the system through components such as the preheater, decomposition furnace, rear kiln inlet, and kiln hood. Compared with traditional landfill and incineration methods, cement kiln co-processing of waste offers significant advantages. However, due to its late start, the technology, operation, and supervision systems are not yet fully mature.
A glass furnace is a thermal equipment for glass melting constructed with refractory materials. The service efficiency and lifespan of a glass furnace largely depend on the types and quality of refractory materials. The development of glass production technology is significantly reliant on advancements in refractory material manufacturing technology. Therefore, the rational selection and use of refractory materials are crucial in the design of glass furnaces. To achieve this, two key points must be mastered: first, the characteristics and applicable parts of the selected refractory materials; second, the service conditions and corrosion mechanisms of each part of the glass furnace.
Silicon nitride bonded silicon carbide materials are used to replace traditional carbon materials on the side walls of electrolytic cells. They can also serve as thermocouple protection tubes for temperature measurement, lining materials for aluminum smelting furnaces, linings for aluminum ladles ("baozi"), crucibles, pumps and pipelines for conveying aluminum liquid, valves, aluminum casting molds, and riser tubes for forming automotive wheel hubs.
Electro - fused α-β corundum bricks are composed of approximately 50% α-Al₂O₃ and 50% β-Al₂O₃. The interlaced crystallization of these two phases forms an extremely dense organizational structure. These bricks exhibit excellent resistance to strong alkali corrosion.
The physical function of fireproof material is in to its high temperature environment is used mediumly crucial. It is the function of a few crucial physics of fireproof material below: 1. Fireproof degree (Refractoriness) definition: Fireproof spending is to show fireproof material can issue the ability that maintains its physics and chemical stability in high temperature, normally the melting point with material or softening point...
In the construction of kiln furnace, fireproof material expands seamed stuff stuff is very serious, they are used at absorbing material to expand in the heat below high temperature, prevent lining structure to suffer because of expanding be restricted and produce crackle or damage. It is below a few expand commonly usedly seam stuff stuff: 1. Blanket of fiber of pottery and porcelain: Blanket of fiber of pottery and porcelain is had good high temperature resistant function...
Splashing broken bits to protect furnace is one kind is used at lengthening converter of converter furnace life, protection the technique of fireproof material, especially the converter in process of steel of commonly used Yu Lian. Through using slag medium material is below the concussion of high-pressured gas splash arrives on furnace wall, form layer of a protection broken bits, be opposite in order to reduce melt molten steel and slag of fireproof material erode, from...
Fireproof burner brick basically is used at the combustion system of all sorts of high temperature furnace, mix in need high temperature especially safe flaming circumstance. It is the main application domain of fireproof burner brick below: 1. Metallurgy industry is in the metallurgy equipment such as blast furnace, cupola and electric arc furnace, fireproof burner brick burns the fuel such as gas, natural gas or oil with Yu Ran, in order to ensure...
Light qualitative adiabatic firebrick is one kind has the fireproof stuff of rate of low volume density, tall hole and good heat proof quality, basically use at the liner of industrial kiln furnace and equipment and thermal insulation. Its characteristic is to have favorable adiabatic effect, can hold stable structure and fireproof property below high temperature environment at the same time, apply extensively at of all kinds high temperature...
Raising steel to wrap liner to use a number is steely cost is reduced in production, raise high yield can one of crucial step. Steel bag liner bears below high temperature condition the concussion of molten steel, chemistry is eroded and thermal stress, accordingly its service life affects the success of steelmaking process directly. Include the use number of liner to raise steel, the following kinds of arrange...
Firebrick undertakes maintenance regularly in the use need in kiln furnace, the safety of kiln furnace, safety moves and prolong the service life of firebrick in order to ensure. The main reason that defends regularly and measure include: 1. Monitor the wear out condition that wears away to check firebrick regularly with attaint, hit area in high temperature and Gao Chong especially. Whether does observation have break...
