Ultra-low carbon steel slab continuous casting special slag
Product description
With the development of modern industry, the international on low carbon steel to the requirement increasingly, this kind of steel [C] is the harmful elements, domestic and foreign production shows that: the process of continuous casting of ultra-low carbon steel is one of the main steps of the carbon, maximum limit reducing the carbon content of the protective slag, to avoid the carbon steel is extremely advantageous. I company production of ultra-low carbon steel CCM mold protect slag, using the latest research results, through the reasonable ingredient control and raw material, and in the very low carbon content slag, effectively control the protection of slag sintering characteristics, such as melting rate of melting performance, solved in ultra-low carbon cases protective slag stable melting process this a difficult technical problems, and satisfy the ultra-low carbon steel ?

- Q: What is the common inorganic fireproof and thermal inuslation matertial?
- inorganic materials of insulation materials 1, inorganic thermal insulation materials are mainly concentrated in the materials that have a certain insulation effect and can achieve level A fireproofing, such as aerogel blanket, glass wool, rock wool, expanded perlite and micro-nano thermal baffle. 2, rock wool production is harmful to human body, workers also do not want to occure the situation under the construction. The cycle of rock wool construction plate is long about 2 years from construction to production. The supply of the domestic wool market also cannot meet the requirements for use. 3, expanded perlite has great weight and high water absorption. 4, the insulation performance of micro-nano insulation panels is 3-5 times that of conventional insulation materials, commonly used in high temperature environment, but is more expensive. 5, aerogel blanket is level A1 inorganic fireproofing building materials, thermal conductivity at room temperature is 0.018W / (K · m), and absolutely waterproofing, its insulation performance is 3-8 times of traditional materials, which can replace the unenvironment-friendly froconventional flexible material with poor insulation properties, such as glass fiber products, asbestos insulation felt and silicate products.
- Q: The fire prevention board line is made of what material?
- Crural line: wooden, in the market, there are sjoiner woodblock, peach wood and artificial engraving. The second classification is stone and the most used one is the marble graved or ceramics well-made one is taken as the first choise. Its price is a little bit expensive than the wooden one, but also a suitable choise. Condole supports: It has various category. The general furniture choose plaster and anti-firing plate and the other also have a choice of steel. You can make a suitable choice according to the need. If it is contracting project, it depends on your project specific plan and funds plan. In a word, beauty and harmony should be given priority since it is the source of design.
- Q: whether the fire resistant level of aerated concrete building blocks can reach the grade one?
- the fire resistant level of aerated concrete building blocks can reach the grade one level. Aerated concrete strength grade shall be divided according to the concrete cubic compressive strength value. Use the symbol C and the cube compressive strength value (in N / mm2 or MPa gauge) to express. According to GB50010-2002 "concrete structure design specifications" provisions, ordinary concrete is divided into fourteen levels, namely: C15, C20, C25, C30, C35, C40, C45, C50, C55, C60, C65, C70, C75, C80 .
- Q: What are the fire resistance ratings of the glass partition?
- Hello, friend. The glass partition system is composed entirely of metal structures, glass, color plate and other materials which also has fire resistance capacity. When the inner structure of the system is steel structure, the fire resistance of which is 30 mins, 60mins or even longer.
- Q: Which fire-resistant materials have good viscidity?
- The viscidity of fire-resistant materials is also known as the binding performance of fire-resistant materials. It can be divided into chamotte and chemical binder. Both can work at normal or high temperature. The most commonly used chamotte are soft clay and aluminate cement. The commonly used chemical binders include sodium silicate, phosphoric acid, aluminum sulphate, aluminium phosphate, phenolic resin, etc. Fire resistant material is a complicated and overloaded system and we cannot know its materials and chemical components from the name alone. Both gunning mix and repair mix contain binder components. If they can used after adding water, then they may contain clay or fire resistan aluminum silicate cement.
- Q: What substitutes are available for high-end refractories in addition to zircon sand?
- If you want to use environmentally friendly products, please use recycled Mo powder.
- Q: What is the fire endurance of fireproof glass cotton?
- Good thermal insulation and thermal insulation. thermal insulation and thermal insulation depends on the heat conductivity coefficient of glass?silk λ=0.043W/m2K. good fireproof?performance, it's fire-resistant capacity is more than 1000 ℃.
- Q: What is high alumina refractory?
- It refers to inorganic non-metallic material with refractoriness of higher than 1580℃. Refractoriness refers to the celsius temperature that the cone-shaped refractory sample without load can resist, and under which the sample won't soften and melt down. Refractory material appears together with high temperature technology, and roughly dates from the Middle Bronze age. In the Eastern Han Dynasty (AD25~AD220) of China, fireclay refractories has been used as furnace refractories and saggers for making porcelains. In the early 20th century, refractory material develops toward the direction of high purity, high dense and ultra high temperature products, and meanwhile unshaped refractory and refractory fiber with no need of firing at all and with low energy consumption appear.
- Q: What can red stone refractory do?
- In severe cases, the resistance to high temperature without softening down the Celsius temperature. Refractory materials are widely used in metallurgy, chemical, petroleum, machinery manufacturing, silicate, power and other industrial fields, the largest amount of metallurgical industry, accounting for 50% ~ 60% of the total output. Chinese use less impurity clay in more than 4000 years ago, firing pottery, and have been able to cast bronze. In the Eastern Han Dynasty (AD 25 ~ 220) have been used to make clay refractory kiln firing porcelain material and sagger. At the beginning of twentieth Century, the development of refractories to high purity, high density and ultra high temperature products, while developing completely without firing, small consumption of unshaped refractory materials and high refractory fiber (160 for industrial furnace refractories above 0 DEG C). The former, such as alumina refractory concrete, is often used in large chemical plants, ammonia synthesis plant, two - stage reformer furnace wall, the effect is good. Since 50s, the rapid development of atomic energy and space technology, the development of new energy technology, requires the use of special refractory material of high temperature resistance, corrosion resistance, thermal shock resistance, erosion has excellent properties, such as melting point above 2000 DEG C, oxide refractory compounds and high temperature composite refractory materials.
- Q: Refractory inquiries
- Neutral refractory is refractory material which is difficult to react with acid or alkaline slag at high temperature, such as carbon refractory and chrome refractory. Some of the high alumina refractories are also attributed to this category.
